Description

Technical Field

[0001] The invention belongs to the field of shoe manufacturing, and in particular relates to an adjustable measuring device for testing the fit of a shoe. Background Art

[0002] Comfort is one of the important requirements of consumers for shoe quality. Comfort is a personalized experience, which is a subjective evaluation of the stimulation of external things (i.e. the space inside the shoe) through the senses. For a long time, there has been no unified and clear definition of shoe comfort at home and abroad. In March 2011, the National Technical Committee for Shoemaking Standardization held a seminar on shoe comfort. Many domestic shoemaking companies and relevant experts and scholars participated in the discussion meeting and finally determined the definition of shoe comfort, that is, shoe comfort is a comprehensive evaluation of people's psychological and physiological feelings about shoes during wearing, which refers to the degree to which shoes meet the morphological structure of human feet and the requirements of wearing functions, mainly including: fit, functionality, shoe environment, etc.

[0003] Among them, the fit includes: the structural size of the shoe, the matching of the shoe and the foot, the pressure of the shoe on the foot (dorsum and sole), etc.; the functionality includes: stability, shock absorption, softness, anti-slip, lightweight; the environment inside the shoe includes: moisture absorption, breathability, hygiene, etc. The proposal of this definition provides a direction and evaluation index for the quantification and research of shoe comfort in the future.

[0004] Among all comfort indicators, foot fit is one of the most critical factors. Although the foot can be put into shoes of different sizes and shapes due to its large deformability, inappropriate shoes may cause a variety of foot problems and easily cause leg fatigue, thereby increasing the risk of slipping and falling. Studies have shown that indicators such as the height of the big toe, the height and length of the instep, and the width of the forefoot and heel are the most critical factors affecting the subjects' evaluation of shoe comfort. Individualization of these indicators can significantly increase comfort and improve the protective function of the shoe.

[0005] Although everyone can quickly judge whether a pair of shoes fits, the fit is a subjective and objective feeling based on personal foot shape and tightness preferences and habits, which depends on individual differences. It is very difficult to objectively determine whether a pair of shoes is comfortable. The factors that affect people's judgment of shoe comfort are numerous and complex.

[0006] China's light industry standard QB / T 4333-2012 "Footwear Fit Evaluation Method" provides a relatively comprehensive test and evaluation method. In the static fit inspection, it is stipulated that the evaluator should wear the test sample shoes and maintain a normal standing posture, with the weight evenly distributed on both feet and the body slightly leaning forward. The evaluator starts from the front upper and checks the fit of the front upper toe, metatarsophalange, tarsal circumference, waist dimple and heel of the test shoe in turn. When the tester asks the evaluator about the fit feeling, he must ensure that the fit feeling is correctly expressed, but no guiding language should be used to avoid deviations in the results. In summary, the conventional fit evaluation process takes a long time to operate, the process is relatively cumbersome, and the accuracy cannot be guaranteed. In addition, scientific literature points out that comfort is also closely related to the individual's wearing experience, foot shape, gender, and weight.

[0007] In theory, placing pressure sensors on the test subject's foot or in the test shoe can measure the objective pressure value between the foot and the shoe, and evaluate the pressure in key areas of the foot, thereby evaluating the comfort of different shoes. However, it is unlikely to find representative "test subjects" to conduct in-shoe pressure or comfort evaluations of different shoes. Therefore, setting up a device that can simulate the human foot shape to objectively measure the fit of shoes will be conducive to objectively evaluating the pressure distribution in the shoe and providing objective data on the fit of different parts of the shoe, thereby providing a testing method for accurately, effectively and quickly evaluating the fit of shoes for different shoe models. Summary of the invention

[0008] The purpose of the present invention is to provide an adjustable measuring device for testing the in-shoe fit, so as to solve the problems that the existing in-shoe fit evaluation process has a long operation time, a complicated process and cannot guarantee the accuracy.

[0009] To achieve the above-mentioned purpose, the specific technical scheme of the adjustable measuring device for testing the fit of a shoe of the present invention is as follows:

[0010] An adjustable measuring device for testing the fit of a shoe comprises a foot model and a pressure sensor arranged on the foot model, wherein the foot model comprises at least two groups of module components, each group of module components comprises at least one model of module body, and the module bodies in the module components can be spliced ​​together to form different types of foot models.

[0011] Furthermore, the models of the module bodies in the module assembly include size models and softness and hardness models. Module bodies of different models in the module assembly are spliced ​​together to form foot models with different sizes and softness and hardness.

[0012] Furthermore, the foot model is made of silicone.

[0013] Furthermore, the foot model is a hollow structure.

[0014] Further, the pressure sensors are arranged at positions on the foot model corresponding to the locations of the bony protrusions and muscle protrusions of the foot.

[0015] Furthermore, the pressure sensor is a thin-film pressure sensor.

[0016] Further, the foot model includes a toe module, a forefoot module, a midfoot module, and a heel module which are connected in sequence.

[0017] Furthermore, a first pressure sensor is disposed at a position of an upper portion of the midfoot module close to the inner side, and a sixth pressure sensor is disposed at a position of a lower portion of the midfoot module close to the inner side.

[0018] Furthermore, a second pressure sensor is arranged on the upper part of the forefoot module corresponding to the position of the first metatarsophalangeal joint, a fourth pressure sensor is arranged on the side part corresponding to the position of the first metatarsophalangeal joint, a fifth pressure sensor is arranged on the lower part corresponding to the position of the first metatarsophalangeal joint, and a third pressure sensor is arranged on the side part of the forefoot module corresponding to the position of the fifth metatarsophalangeal joint.

[0019] Furthermore, a seventh pressure sensor is arranged at the lower part of the heel module corresponding to the position of the heel, and an eighth pressure sensor is arranged at the rear part of the heel module corresponding to the position of the heel.

Through a quantitative evaluation method, the matching degree between the foot and the shoe can be accurately and effectively evaluated, thereby providing data support for the development and scientific research of footwear products related to improving the fit.

[0026] In order to better understand the purpose, structure and function of the present invention, the adjustable measuring device for testing the fit of a shoe according to the present invention is further described in detail below with reference to the accompanying drawings.

[0027] The adjustable measuring device for testing the fit of a shoe of the present invention comprises a foot model and a pressure sensor arranged on the foot model, wherein the foot model comprises at least two groups of module components, each group of module components comprises at least one module body of a model, and the module bodies in the module components can be spliced ​​and arranged with each other to form different types of foot models. It should be noted that the number of module components is not specifically limited in the present invention. The more the number, the higher the accuracy of the test, but the more complicated the test process will be. In the following specific example, four groups of module components are arranged, which is only a preferred example and is not limited thereto.

[0028] Specifically, the model of the module body in the module assembly may include a size model and a hardness model. The module bodies of different models in the module assembly are spliced ​​together to form foot models of different sizes and hardnesses, so as to achieve the purpose of studying the fit of different foot types. It can be understood that size and hardness are two more obvious characteristics of the foot, so these two characteristics are used as model design parameters in the present invention. According to different design requirements, other characteristics of the foot can also be selected as model design parameters, and this is not specifically limited in the present invention.

[0029] The size model can be limited by the length, thickness and width of the module body. A module body of multiple sizes and models can be set in a module assembly. At the same time, preferably, the foot model in the present invention is made of silicone material, thereby adjusting the silicone density to match the same elastic modulus as the human muscle and bone structure to achieve the effect of reflecting the foot characteristics of different softness and hardness. It can be understood that the present invention does not specifically limit the number of module body models in each module assembly. The more the number, the more foot types can be tested. In addition, the material of the foot model can also be selected from other soft materials, not limited to silicone materials.

[0030] Furthermore, the pressure sensors on the foot model are respectively arranged on different module components. Preferably, the pressure sensors are arranged at positions on the foot model corresponding to the bony protrusions and muscle protrusions of the foot, so as to facilitate the testing of the pressure conditions at the positions, wherein the greater the pressure, the worse the comfort, and the more evenly the pressure distribution, the better the fit. Of course, it is understandable that, because different people have different thresholds of comfort-pressure, the number and arrangement of the pressure sensors should be flexibly adjusted according to the actual situation to meet different research needs, and this is not specifically limited in the present invention.

[0031] like Figures 1 to 5As shown, it is a specific example of the adjustable measuring device for testing the fit of a shoe according to the present invention. In this embodiment, the foot model includes four sets of module components, namely, a toe module 10, a forefoot module 20, a midfoot module 30 and a heel module 40 connected in sequence. Among them, according to different foot shape characteristics, the toe module 10, the forefoot module 20, the midfoot module 30 and the heel module 40 are respectively provided with multiple models, and the purpose of forming foot shapes of different sizes can be achieved by splicing and combining the above four modules of different models.

[0032] Furthermore, the toe module 10, the forefoot module 20, the midfoot module 30 and the heel module 40 in this embodiment are all silicone models, and can be directly spliced ​​with each other by pasting, plugging, snapping or other similar fixing methods, as long as they are convenient for disassembly and assembly. In addition, preferably, the toe module 10, the forefoot module 20, the midfoot module 30 and the heel module 40 in this embodiment are hollow structures, which are not only convenient for splicing, but also the data transmission lines of each pressure sensor can be set in the hollow structure, which is convenient for installation and use, wherein the sensor data can be connected to a computer or transmitted to a mobile phone or other tablet device through a Bluetooth transmitter, so as to facilitate intuitive reading of the pressure values ​​of the sensors on each module.

[0033] Further, if Figure 1 and Figure 3 As shown, in this embodiment, the forefoot module 20 is provided with a second pressure sensor 2, a third pressure sensor 3, a fourth pressure sensor 4 and a fifth pressure sensor 5. Specifically, the second pressure sensor 2 is provided at the upper part of the forefoot module 20 corresponding to the position of the first metatarsophalangeal joint; the fourth pressure sensor 4 is provided at the side of the forefoot module 20 corresponding to the position of the first metatarsophalangeal joint; the fifth pressure sensor 5 is provided at the lower part of the forefoot module 20 corresponding to the position of the first metatarsophalangeal joint; the third pressure sensor 3 is provided at the side of the forefoot module 20 corresponding to the position of the fifth metatarsophalangeal joint. Among them, the second pressure sensor 2, the third pressure sensor 3, the fourth pressure sensor 4 and the fifth pressure sensor 5 can be used to study the fit of the upper bending part.

[0034] Further, if Figure 1 and Figure 3 As shown, in this embodiment, the midfoot module 30 is provided with a first pressure sensor 1 and a sixth pressure sensor 6. Specifically, the first pressure sensor 1 is provided at a position close to the inner side of the upper part of the midfoot module 30, and the sixth pressure sensor 6 is provided at a position close to the inner side of the lower part of the midfoot module 30. The first pressure sensor 1 and the sixth pressure sensor 6 can be used to study the fit of the foot and the arch.

[0035] Further, if Figure 3 and Figure 5As shown, in this embodiment, the heel module 40 is provided with a seventh pressure sensor 7 and an eighth pressure sensor 8. Specifically, the seventh pressure sensor 7 is provided at the lower part of the heel module 40 corresponding to the position of the heel, and the eighth pressure sensor 8 is provided at the rear part of the heel module 40 corresponding to the position of the heel. The seventh pressure sensor 7 and the eighth pressure sensor 8 can be used to study the fit of the heel.

[0036] The above-mentioned areas where pressure sensors are set are all key areas corresponding to bony protrusions and muscle bulges, and are also key parts that greatly affect the fit of the foot. Of course, it can be understood that the above are only preferred examples, and the present invention is not limited to only these pressure sensors. According to actual conditions, more pressure sensors can be set and arranged in various areas of the foot model to ensure the purpose of different studies. Among them, preferably, the pressure sensor in the present invention can select a flexible pressure sensor or other forms of thin-film pressure sensor, and the sensor distribution density on the sensor can be freely set according to experimental needs.

[0037] The adjustable measuring device for testing the in-shoe fit of the present invention will greatly assist shoe last makers and R&D personnel in their research on different types of shoes and shoe lasts, and can quantify the effects of different shoe lasts and shoe bodies on the foot fit, thereby providing a data basis and technical support for ensuring the matching of the foot and the shoe and the optimal design of the last.

[0038] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
