Insole Arch Support Design for Footwear Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insole design methods fail to adequately combine user comfort needs with the requirements of industrial production, particularly in safety footwear, where comfort and manufacturing compatibility are not adequately addressed.
Innovation Solution
A designing method that defines configuration parameters for a support for the plantar arch, such as initial and final portions, depth, and height, along with foot length and width, to categorize insoles into low, medium, and high types, allowing for industrial manufacturing while enhancing user comfort through specific dimensional and material distribution, including high-density and memory-effect polyurethane materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional insole design methods are used, then manufacturing simplicity is maintained, but user comfort needs are not adequately satisfied
Solution Approach 1:
The patent applies parameter changes by defining specific configuration parameters (initial portion, final portion, depth, height) that determine insole geometry. These parameters are adjusted based on statistical foot measurements to optimize comfort while maintaining industrial manufacturability through standardized design variables.
Solution Approach 2:
The patent implements local quality by creating differentiated insole regions with specific functional properties. The insole is divided into distinct zones (heel portion, arch support portion, forefoot portion) with varying depths, heights, and material densities to address local comfort needs while following a manufacturable design framework.
2Ease of operation
If customized insole design for individual foot shapes is implemented, then user comfort is improved, but production complexity increases
Solution Approach 1:
The patent uses copying by creating standardized insole designs that replicate the essential anatomical support features of custom-fitted insoles. Based on statistical analysis of foot measurements, the patent defines configuration parameters that copy the beneficial geometric characteristics of individual foot shapes into universally applicable standardized designs.
Solution Approach 2:
The patent achieves universality by designing insoles with configuration parameters that can accommodate variations in foot shapes across different users. The standardized design with adjustable parameters serves multiple foot types and comfort requirements, eliminating the need for individual customization while maintaining effectiveness.

AI summary
A designing method of a insole for a user is described, comprising the steps of: defining the following configuration parameters of supports for plantar arch (SZ): initial portion of support for plantar arch; final portion of support for plantar arch; depth of support for plantar arch; height of support for plantar arch AH. The method further comprises the following steps: defining a first plurality of dimensional parameters of a foot (200) including: a foot length; a foot width; defining, by means of said configuration parameters, three types of supports for plantar arch in accordance with the mathematical relationships expressed as a function of the first plurality of dimensional parameters of a foot and such as to identify: a support for low plantar arch, a support for middle plantar arch and a support for high plantar arch.
