Foot Positioning Device Using Heel Strap Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals, especially children or novice athletes, find it difficult to maintain proper foot placement in activities requiring specific foot positions, such as plantar flexion, due to lack of experience or muscle memory.
Innovation Solution
A foot positioning device comprising proximal, distal, and heel straps that apply a force to bias the foot into a plantar flexion position, which can be integrated into a sock, shoe, or worn separately, with optional electronic sensors to track performance and provide feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no device is used, then the individual can move freely without restriction, but the foot cannot be maintained in the preferred plantar flexion position
Solution Approach 1:
The foot positioning device acts as an intermediary between the individual's foot and the desired plantar flexion position. The device includes a proximal strap connecting to the ankle/lower leg, a distal strap connecting to the foot, and a heel strap that applies force to bias the foot into the preferred position. This intermediary mechanical system provides the necessary force to maintain foot positioning without requiring the individual to consciously control it.
2Reliability
If a foot positioning device is used, then the foot can be biased toward the preferred position, but the device structure becomes more complex
Solution Approach 1:
The foot positioning device is segmented into three distinct functional components: a proximal strap for anchoring to the ankle or lower leg, a distal strap for connecting to the foot, and a heel strap for applying the biasing force. This segmentation allows each component to perform its specific function independently while working together as a unified system, making the overall device more manageable and adjustable.
3Manufacturing precision
If the device applies strong force to maintain position, then the foot placement is more accurate, but comfort and ease of wear deteriorates
Solution Approach 1:
The foot positioning device employs dynamic, adjustable straps that can be customized to fit different individuals and activity requirements. The straps can be adjusted to provide the appropriate amount of force for maintaining foot position while allowing for comfort and adaptability. This dynamic adjustability enables the device to balance positioning accuracy with user comfort across different users and situations.
