Adjustable Foot Support Device for Secure Shoe Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot support devices, such as shoe inserts, do not securely fit within shoes and require customization or multiple purchases to accommodate different shoe sizes, leading to discomfort and inconvenience.
Innovation Solution
A foot support device featuring a sock member with an integrated, longitudinally adjustable impact reduction member made from foam or gel, secured within the sock using durable techniques like stitching, to provide consistent comfort and impact reduction across various foot sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional shoe inserts are used, then impact reduction is provided, but the inserts do not securely fit within shoes and require customization or multiple purchases to accommodate different shoe sizes
Solution Approach 1:
The impact reduction member is made longitudinally adjustable to dynamically adapt to different foot lengths. The member can be extended or repositioned along the longitudinal axis to accommodate various shoe sizes, eliminating the need for multiple inserts or customization while ensuring a secure fit in each shoe pair.
Solution Approach 2:
The foot support device is designed as a universal solution that can be used across multiple shoe pairs and foot sizes. The adjustable impact reduction member allows a single insert to serve multiple functions and fit various shoe types, replacing the need for multiple specialized inserts.
2Reliability
If conventional shoe inserts are used, then impact reduction is provided, but the inserts are not secured within the shoe and move within the interior causing discomfort
Solution Approach 1:
The sock member and impact reduction member are merged into an integrated assembly where the impact reduction member is secured within the sock member. This combination ensures that the insert remains stationary and secure within the shoe, eliminating movement and discomfort while maintaining impact reduction functionality.
3Adaptability or versatility
If the impact reduction member is made adjustable, then accommodation of various foot sizes is achieved, but the device complexity increases
Solution Approach 1:
The impact reduction member is segmented into adjustable sections or components that can be independently positioned or extended. This segmentation allows for simple longitudinal adjustment mechanisms that accommodate various foot sizes without requiring complex systems, maintaining ease of use while achieving adaptability.

AI summary
A foot support device configured to be donned by a user and subsequently inserted into a shoe that is operable to provide impact reduction for a user. The foot support device includes a body having a first portion and a second portion contiguously formed. The body includes a cavity configured to receive a human foot therein. A bottom portion is secured to the second portion of the body and extends the length thereof. A void is present intermediate the bottom portion and the second portion of the body. Disposed within the void is an impact reduction member. The impact reduction member includes a first portion, a second portion and an expansion member. The expansion member is intermediate the first portion and second portion of the impact reduction member and is operable to allow the longitudinal extension of the impact reduction member.
