Anterior Tibialis Exercise Device With Adjustable Foot Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices fail to effectively target anterior tibialis muscles due to lack of adjustable feet engagement means for users with varying foot sizes.
Innovation Solution
An exercise device comprising a weight engagement element, a sliding element, and a locking element, which includes a dorsum bar, a heel bar, and a locking mechanism to securely position weights for performing alternating dorsiflexion and plantarflexion movements, accommodating various foot sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed feet engagement means is used in exercise devices, then device structure is simple, but it cannot accommodate users with varying foot sizes
Solution Approach 1:
The patent applies the dynamics principle by making the feet engagement means adjustable rather than fixed. The barbell features movable collars that can be positioned at different locations along the bar, allowing the engagement means to adapt to various foot sizes and positions. This dynamic adjustment capability resolves the contradiction by enabling versatility without requiring multiple fixed structures.
Solution Approach 2:
The feet engagement means is segmented into separate adjustable components (collars that can be independently positioned) rather than a single fixed structure. This segmentation allows each component to be optimized for different user requirements, providing adaptability while maintaining relatively simple individual component designs.
2Reliability
If weights are not securely retained on the weight bar, then device operation is simple, but weight movement during use compromises safety
Solution Approach 1:
The locking mechanism is engaged before the exercise begins, securing the weights in place prior to use. This preliminary action ensures that weights are retained safely throughout the exercise motion, preventing movement during use while maintaining a relatively simple overall device structure.
Solution Approach 2:
The collar acts as an intermediary element between the weight bar and the weights, providing the locking function without requiring complex integration into the barbell structure itself. This intermediary component simplifies the overall design while ensuring reliable weight retention.

AI summary
An exercise device targeting anterior tibialis muscles which specifically targets anterior tibialis muscles includes weight engagement, sliding, and locking elements. The weight engagement element comprises a dorsum bar, which is attached to and which extends bidirectionally from a first end of a weight bar. The sliding element comprises a heel bar, which is attached to and which extends bidirectionally from a first terminus of an extension bar. A second terminus of the extension bar is slidable along and releasably securable to the weight bar so that the dorsum bar and the heel bar can be fit to feet of a user. The weight bar is insertable through the central hole of one or more weights so that the one or more weights abut the extension bar. The locking element is slidable along and releasably securable to the weight bar to retain the one or more weights in position.
