Inflatable Member Customizing Footwear Width and Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footwear technologies lack an efficient method to customize the fit of articles of footwear, particularly in adjusting the width to accommodate individual foot shapes and sizes, which can lead to discomfort and poor fit.
Innovation Solution
An inflatable member with an adjustable portion and a fluid port, allowing for inflation and adjustment to fit various foot sizes, is integrated into the footwear, enabling customizable width adjustment and graphic application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional footwear manufacturing methods are used, then production is simple and cost-effective, but the fit cannot be customized to individual foot shapes and sizes
Solution Approach 1:
The patent introduces an inflatable member with an adjustable portion that can change size and shape dynamically. The inflatable member includes a chamber that can be inflated or deflated to adjust the width and volume of the footwear, allowing the same shoe to fit different foot shapes and sizes. This dynamic adjustment mechanism resolves the contradiction by enabling customization without requiring multiple separate shoe designs.
Solution Approach 2:
The patent changes the physical state and dimensions of the footwear by controlling the inflation of the inflatable member. By adjusting the volume and shape of the inflatable chamber, the effective size and fit of the footwear can be modified. This parameter change approach allows a single footwear design to adapt to various foot dimensions, improving adaptability while maintaining manufacturing simplicity.
2Adaptability or versatility
If multiple shoe sizes are produced to fit different foot shapes, then fit customization is achieved, but inventory complexity and cost increase
Solution Approach 1:
The patent makes a single footwear design universal by incorporating an inflatable member that can be adjusted to fit different foot shapes and sizes. Instead of manufacturing multiple shoe variants for different sizes, the same shoe can be inflated or deflated to accommodate various foot dimensions. This multi-functionality approach eliminates the need for extensive inventory while maintaining fit customization capabilities.
3Stability of the object's composition
If the footwear structure is made more rigid to maintain shape, then structural stability is improved, but adaptability to different foot shapes is reduced
Solution Approach 1:
The patent creates a dynamic structural system where the inflatable member can change its rigidity and shape based on inflation state. When inflated, the member provides structural support and maintains shape; when deflated, it allows for shape modification and adaptation to different foot contours. This dynamic structural approach resolves the contradiction between stability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inflatable member provides a customizable fit by expanding to accommodate different foot widths, enhancing comfort and reducing the need for multiple shoe sizes, while also allowing for graphic transfer on curved surfaces.
Implementation Method 1
filling an inflatable member with fluid, changing the position of an adjustable portion disposed inside the inflatable member
Implementation Method 2
heating the deformable membrane and transferring the graphic to the surface
