Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to FIG. 1 of the specification, in this embodiment, a method for optimizing the somatosensory parameters of a bathroom product adjustment switch is provided, and the method includes the following steps.

Step 101 : Acquire the values of evaluation-related indicators of a plurality of adjusting switch samples of sanitary products to be evaluated belonging to the same category. Wherein, the adjusting switch samples of sanitary products to be evaluated belonging to the same category are preferably standard products, and the adjusting switches of sanitary products may be adjusting switches of shower products, adjusting switches of toilet products, etc., which are not limited in the present invention. The adjustment switch can be one of a button, a knob or a push button, etc. The present invention does not limit the type of the adjustment switch for sanitary products.

In this step, the value of the evaluation-related index includes the value of the damping force index of the adjustment switch sample of the bathroom product to be evaluated and the value of the somatosensory parameter evaluation index, and the value of the somatosensory parameter evaluation index is the experiencer adjusting the bathroom The evaluation value of the somatosensory parameter of the product adjustment switch sample, the evaluation-related index may also be the force exerted by the experiencer when adjusting the bathroom product adjustment switch sample, the experience scene of the experiencer, the number of times experienced by the experiencer within a fixed time, etc. The evaluation-related index is a factor that affects the experiencer's evaluation of the somatosensory parameter of the adjustment switch of the bathroom product to be evaluated. The evaluation-related index includes but is not limited to the above-mentioned influencing factors, which are not limited in the present invention.

In this step, the value of the damping force index is calculated from the value of the subordinate sub-indices of the damping force index, and the values of the subordinate sub-indices of the damping force index include but are not limited to:

The ideal damping force of the adjustment switch sample of the bathroom product to be evaluated and the water pressure switching force increment of the adjustment switch sample of the bathroom product to be evaluated; the value of the damping force index is calculated by the following formula:

x _k =X _k +x _k,0

Wherein, x _k is the value of the damping force index of the k-th bathroom product adjustment switch sample to be evaluated, and X _k is the ideal damping force value of the k-th bathroom product adjustment switch sample to be evaluated. Or, when experiencing the same sample of the adjustment switch of the bathroom product to be evaluated, the value of X _k is fixed; x _k,0 is the value of the water pressure switching force increment of the kth sample of the adjustment switch of the bathroom product to be evaluated. ; The design and use of sanitary products are usually adapted to the waterway structure, so with the change of the pressure at the water supply end, the value of the damping force index will also change accordingly. In the present invention, x _k,0 is the adjustment switch of the sanitary product to be evaluated. The samples were used under the same water pressure.

Step 102, take the damping force index of the adjusting switch sample of the sanitary product to be evaluated as the variable x, take the evaluation index of the somatosensory parameter of the adjusting switch sample of the sanitary product to be evaluated as the relevant variable of the variable x, and calculate according to the least squares method Obtain the nth fitting curve f(x), where n≤10;

Step 103: Determine the variable value of the damping force index of the sanitary product corresponding to the target somatosensory parameter evaluation index of the adjustment switch of the same type of sanitary product according to the n-th fitting curve f(x), and specify the damping force of the sanitary product The variable value of the force index is the production value of the damping force index of the sanitary product, so as to optimize the somatosensory parameter of the sanitary product adjusting switch. In this step, the target somatosensory parameter evaluation index is a parameter determined after comprehensively considering factors such as user experience, market demand and resource allocation in production. According to the n-time fitting curve f(x), in the n-time In the fitting curve f(x), the variable value of the damping force index corresponding to the target somatosensory parameter evaluation index is determined, because the n-time fitting curve f(x) is the damping force index of the adjusting switch sample of the sanitary product to be evaluated. is the variable x, and the somatosensory parameter evaluation index of the adjustment switch sample of the bathroom product to be evaluated is the relevant variable of the variable x, and the fitting curve is calculated according to the least squares method, so the n-time fitting curve f( In x), determine the variable value of the damping force index corresponding to the evaluation index of the target somatosensory parameter, wherein the variable value of the damping force index is determined after considering the evaluation of the somatosensory parameter of the sanitary product adjustment switch by the bathroom product experiencer. The value of the damping force index corresponding to the target somatosensory parameter evaluation index is specified, and the variable value of the damping force index of the sanitary product is specified as the production value of the damping force index of the sanitary product, and the production value of the damping force index of the sanitary product The value is directly applied to the production process to guide production, avoiding the situation where the somatosensory parameters of sanitary products in the prior art are not clearly defined. Although the user's evaluation of the somatosensory parameters of the adjustment switch of sanitary products is an important reference for product design, However, the user's evaluation of the somatosensory parameters of the adjustment switch of the bathroom product cannot provide an effective reference for the product design process. The technical scheme of the present invention is simple to operate, combines the damping force of the adjustment switch of the bathroom product with the evaluation of the somatosensory parameter of the adjustment switch of the bathroom product by the user of the bathroom product experiencer, comprehensively considers the factors affecting the somatosensory parameter of the adjustment switch of the bathroom product, and is a bathroom product. The optimal design of adjusting switch somatosensory parameters provides an effective theoretical basis.

In one example, the n-order fitting curve f(x) is a quadratic fitting curve, and f(x)=a(x+b) ² +c; wherein a, b and c are all based on the minimum The value calculated by the quadratic method, the quadratic fitting curve can intuitively reflect the variable value of the damping force index corresponding to the target somatosensory parameter evaluation index, which is convenient to be directly applied to the production process to guide the production. Set the full score of the somatosensory parameter of the adjustment switch of the bathroom product to be evaluated as m ₀ , and specify c=m ₀ -m, then the quadratic fitting curve is f(x)=a(x+b) ² +m ₀ - m, where m is specified as the experience deviation amount caused by other conditions except the influence factors of the damping force of the adjustment switch of the sanitary product to be evaluated. For the adjustment switches of the sanitary products to be evaluated of the same type, the experience deviation m caused by other conditions other than the influence factors of the damping force of the adjustment switches of the sanitary products to be evaluated is a fixed value, and m can be used for arranging the experiencers and setting the experience environment. For reference, the arrangement of the experiencers may include the following factors: the gender of the experiencer, the age of the experiencer, the health condition of the experiencer, the frequency of the experiencer's use of bathroom products, and the experiencer's preference for the types of bathroom products, etc. The setting experience environment can include the following factors: the brightness of the environment, the temperature and humidity of the environment, and the diversity of styles of the bathroom products to be evaluated after excluding the influence factors of the adjustment switch. For example, when the same experiencer experiences different types of products to be evaluated in different environments When adjusting the switch of bathroom products, m can be used as a reference for rationally setting the experience environment. The specific methods are as follows: keep other factors in the experience environment unchanged, control the changes of fixed elements in the experience environment, and refer to m after the change of the fixed elements in the experience environment. The present invention may also include other methods for providing a setting reference for variables that affect the score of the somatosensory parameter, which is not limited in the present invention.

In one example, the value of each sub-indicator of the damping force index is specified by the actual value of the sub-indicator of the damping force index of each adjustment switch sample of the sanitary product to be evaluated. Test the size of the force required to adjust the adjustment switch of the bathroom product to be evaluated when the adjustment switch sample of the bathroom product to be evaluated is not connected to the water supply end and is connected to the water supply end, and the obtained force value is the bathroom product to be evaluated. Adjust the actual value of the dependent sub-indices of the damping force index of the switch sample.

In one example, the step of acquiring the value of the somatosensory parameter evaluation index includes:

Step 201: Acquire the actual value of the somatosensory parameter evaluation index of each of the bathroom product adjustment switch samples to be evaluated; set the full score value of the experiencer's score on the somatosensory parameter of the bathroom product adjustment switch to be evaluated. The full score value of the score for evaluating the somatosensory parameters of the adjustment switch of the sanitary product can be equal to the full score value of the evaluation index of the somatosensory parameter of the adjustment switch of the sanitary product to be evaluated. The score of the somatosensory parameter of the adjusting switch of the sanitary product to be evaluated is the actual value of the somatosensory parameter evaluation index of the adjusting switch sample of the sanitary product to be evaluated. In the method of the present invention, the experiencers can be classified according to gender, and the scores of the experiencers of different genders on the somatosensory parameters of the adjustment switch of the bathroom product to be evaluated are processed separately.

Step 202: Preprocessing the actual value of the somatosensory parameter evaluation index to obtain a corrected value of the somatosensory parameter evaluation index of each of the bathroom product adjustment switch samples to be evaluated;

Step 203: Screen the corrected value of the somatosensory parameter evaluation index of each of the bathroom product adjustment switch samples to be evaluated, remove the corrected value of the somatosensory parameter evaluation index that exceeds a fixed range, and define that the corrected value of the somatosensory parameter evaluation index does not exceed the fixed range The corrected value of the somatosensory parameter evaluation index is the value of the somatosensory parameter evaluation index. The maximum value of the fixed range can be obtained by referring to the full score value of the experiencer's score on the somatosensory parameter of the adjustment switch of the bathroom product to be evaluated. The data processing of the situation requires setting a fixed range of maximum and minimum values. For example, when the experience environment of the experiencer has a positive or negative impact on all the experiencers, it may be considered to increase or decrease the maximum value of the fixed range according to the actual situation. Preferably, the maximum value of the fixed range is a full score value that does not exceed the score of the experiencer on the somatosensory parameter of the adjustment switch of the bathroom product to be evaluated.

In an example, the preprocessing of the actual value of the somatosensory parameter evaluation index includes:

对第j个志愿者体验第k个所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值进行预处理；According to the formula

Preprocessing the actual value of the somatosensory parameter evaluation index of the jth volunteer experiencing the kth bathroom product adjustment switch sample to be evaluated;

为第j个志愿者体验第k个所述待评估卫浴产品调节开关样品的体感参数评价指标的值，f_k,j为第j个志愿者体验第k个所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值，u_j为第j个志愿者体验所有所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值的平均值，u为所有志愿者体验所有所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值的平均值。公式

中，f_k,j保留了体验者体验不同所述待评估卫浴产品调节开关样品的体感参数评分的差异；所述公式中，减去u_j即为在第j个志愿者体验第k个所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值中减去第j个志愿者体验所有所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值的平均值，由于每个体验者对相同种类的所述待评估卫浴产品调节开关样品的体感参数的评分具有主观差异，某个体验者对该类待评估卫浴产品调节开关样品的体感参数评分可能明显高于另一个体验者对该类待评估卫浴产品调节开关样品的体感参数评分，故减去体验者自己体验所有所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值的平均值，有助于消除个体偏差对体验者体感参数的评分带来的影响。in,

is the value of the somatosensory parameter evaluation index for the jth volunteer to experience the kth bathroom product adjustment switch sample to be evaluated, f _k,j is the jth volunteer to experience the kth bathroom product adjustment switch sample to be evaluated The actual value of the somatosensory parameter evaluation index, u _j is the average value of the actual value of the somatosensory parameter evaluation index of the jth volunteer experiencing all the adjustment switch samples of the bathroom product to be evaluated, u is the experience of all the volunteers The average value of the actual value of the somatosensory parameter evaluation index for evaluating the adjustment switch samples of sanitary products. formula

In the formula, f _{k ,j} retains the difference in the somatosensory parameter scores of different samples of the bathroom product adjustment switch to be evaluated by the experiencer; The actual value of the somatosensory parameter evaluation index of the adjustment switch samples of the sanitary product to be evaluated is subtracted from the average value of the actual value of the somatosensory parameter evaluation index of all the adjustment switch samples of the sanitary product to be evaluated by the jth volunteer. There are subjective differences in the scores of the somatosensory parameters of the same type of the adjustment switch samples of the bathroom product to be evaluated, and the somatosensory parameter score of a certain experiencer of the adjustment switch samples of the bathroom product to be evaluated may be significantly higher than that of another experiencer The somatosensory parameter scores of the adjustment switch samples of the sanitary products to be evaluated, so subtracting the average value of the actual values of the somatosensory parameter evaluation indexes of all the adjustment switch samples of the sanitary products to be evaluated by the experiencer himself is helpful to eliminate individual deviations The impact on the scores of the experiencer's somatosensory parameters.

In one embodiment, the actual value of the somatosensory parameter evaluation index of the sanitary product adjustment switch sample to be evaluated includes the scores of the experiencer on the somatosensory parameter of the sanitary product adjustment switch to be evaluated in the same time period. To experience a class of samples within the same time period, the experiencer can repeatedly experience a limited number of objects of a class of samples, so as to accurately feel the difference in the evaluation of somatosensory parameters between different samples. Because the psychological feeling of the experiencer has short-term memory (the experiencer remembers the feeling of evaluating the somatosensory parameters of a certain sample, but cannot accurately describe the degree of the somatosensory parameters of the sample); and for different experiencers, If the time period is not limited and a single sample is taken to experience it in sequence, it may cause misjudgment to a large extent, and the somatosensory parameter evaluation given in the absence of comparison is often unable to accurately define its true "somatosensory parameter evaluation" due to lack of reference. Good or bad", so the experiencer's score on the somatosensory parameters of the adjustment switch of the bathroom product to be evaluated in the same time period is more true and accurate. The present invention can also experience different kinds of samples in the same time period to obtain the scores of the somatosensory parameters of the different kinds of samples, thus, the scores of the somatosensory parameters of the different kinds of samples obtained by the experiencer are more accurate, and the scores of the somatosensory parameters of the different kinds of samples are more accurate. It is also more objective and accurate.

对第j个志愿者体验第k个所述待评估卫浴产品调节开关样品的体感参数评价指标的实际值进行预处理中，所述志愿者为同一生理性别。在一示例中，体验者为青壮年男性和女性(年龄为20-40岁)，男性体验者和女性体验者均为10人，体验对象分别为调节开关为按键、旋钮和推纽的待评估卫浴产品的调节开关，上述样品的数目分别为5把、3把和3把，上述样品的阻尼力指标分别通过推力计或扭力计测得。男性体验者和女性体验者在同一时间段内根据按键、旋钮和推扭分类进行体验，针对每个样品分别有10组女性体验者的数据和10组男性体验者的数据，上述样品的阻尼力指标的值见表1。In one embodiment, the formula is

In preprocessing the actual value of the somatosensory parameter evaluation index of the jth volunteer experiencing the kth bathroom product adjustment switch sample to be evaluated, the volunteers are of the same biological sex. In an example, the experiencers are young and middle-aged men and women (aged 20-40 years old), there are 10 male and female experiencers, and the experience objects are buttons, knobs and push buttons to be evaluated. For the adjustment switch of sanitary products, the number of the above samples is 5, 3 and 3 respectively, and the damping force index of the above samples is measured by thrust meter or torsion meter respectively. Male experiencers and female experiencers experience according to the classification of buttons, knobs and push-torques in the same time period. For each sample, there are 10 groups of female experiencers and 10 groups of male experiencers. The damping force of the above samples The values of the indicators are shown in Table 1.

As shown in Figure 5, when the bathroom product adjustment switch is a button and the experiencer is a woman,

f(x)=0.0660(x-14.2803) ² +10-2.4858;

As shown in Figure 6, when the bathroom product adjustment switch is a button and the experiencer is a male,

f(x)=-0.0779(x-14.9743) ² +10-2.0374;
