Segmented Orthotic Arch Support with Dynamic Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arch support devices either lack flexibility and fail to provide continuous support during active phases of the gait cycle or are too flexible to offer sufficient plantar and arch support.
Innovation Solution
An orthotic device comprising a base member, an arch support portion with multiple arch members surrounded by a covering, allowing for continuous contact with the plantar surface through adjustable positioning and flexibility during the gait cycle, utilizing a base member with a recessed region and arch members with openings for optimal support and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid and uniform arch support devices are used, then stationary support is improved, but support during active gait phases deteriorates
Solution Approach 1:
The arch support device is divided into multiple discrete arch members (first arch member, second arch member, third arch member, fourth arch member) that are spaced apart from each other. These segmented members can independently move and adapt to different foot positions during the gait cycle, providing continuous support while maintaining flexibility. Each arch member can be positioned at different heights relative to the base member, allowing the device to accommodate both stationary and active phases of walking.
2Adaptability or versatility
If flexible insole devices are used, then foot flexibility is improved, but plantar and arch support deteriorates
Solution Approach 1:
The device employs different structural characteristics at different locations. The arch members are positioned at specific heights above the base member to provide targeted support at critical arch regions, while the spaces between arch members and the recessed region allow flexibility in other areas. This localized differentiation enables the device to provide strong support where needed while maintaining overall foot flexibility.
Solution Approach 2:
The arch members are designed to be movable relative to the base member, allowing the device to dynamically adapt to changing foot positions during the gait cycle. The arch members can shift position to maintain contact with the plantar surface during weight-bearing phases while allowing flexibility during non-weight-bearing phases. This dynamic capability resolves the contradiction between providing strong support and maintaining flexibility.
3Strength
If rigid arch support devices are used, then arch support is improved, but continuous contact during gait cycle deteriorates
Solution Approach 1:
The arch members are designed with the capability to move relative to the base member, enabling them to maintain continuous contact with the plantar surface throughout the entire gait cycle. During weight-bearing phases, the arch members can shift to provide support, and during non-weight-bearing phases, they can return to their original positions. This dynamic movement ensures continuous contact and support duration without requiring the device to be rigid throughout.
