Leg Training Device Foot Fixing with Magnetic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leg training devices fail to provide a convenient and stable fixation of weights to the user's foot, compromising comfort, security, and the ability to quickly adjust the weight while ensuring proper limb movement.
Innovation Solution
A leg training device with a support frame connected to foot fixings using elongated profiles and a resistance mechanism featuring a magnetic system, adjustable pulley block system, and tie-rod system, allowing for quick and precise assembly and adjustment of weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weights are fixed securely to the foot using traditional methods, then stability and security are improved, but comfort and ease of adjustment deteriorate
Solution Approach 1:
The foot fixing device is divided into multiple independent components: a heel rest, a toe rest, adjustable straps with buckles, and padding elements. Each component can be independently adjusted or removed, allowing secure weight fixation while maintaining comfort and ease of adjustment. The segmentation enables the user to customize the fit and quickly adjust or remove weights without affecting the entire system.
2Ease of operation
If weights are made easily adjustable for quick changes, then ease of operation is improved, but stability and secure hold deteriorate
Solution Approach 1:
The foot fixing system incorporates dynamic adjustment mechanisms including movable straps with buckles that can be quickly fastened and unfastened, and padding elements that can be repositioned. These dynamic components allow for rapid weight adjustment while maintaining secure hold through the progressive tightening capability of the strap system and the adaptive nature of the padding that conforms to the foot shape.
3Device complexity
If traditional foot fixing methods are used, then device simplicity is maintained, but comfort and secure weight hold deteriorate
Solution Approach 1:
The invention merges multiple functions into an integrated foot fixing assembly: the heel rest and toe rest are combined with adjustable straps, padding, and buckle mechanisms into a single coordinated system. This merging provides enhanced comfort and secure weight hold through the synergistic interaction of components, while maintaining relative simplicity as a unified assembly that attaches to the training device as one unit.
