Sit-up Board Heel Block and Strap Foot Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment for sit-ups often requires manual assistance to hold the feet in place, which is inefficient and not practical for solo practice or official testing scenarios.
Innovation Solution
A sit-up board with a non-slip backboard, heel block, and adjustable foot strap that securely holds the user's feet in place, allowing for unassisted sit-ups on any solid surface, and optionally features a cushioning pad and foldable legs for adjustable incline or decline positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assistance is used to hold feet in place during sit-ups, then foot stabilization is achieved, but efficiency and practicality for solo practice deteriorate
Solution Approach 1:
The device allows users to perform sit-ups independently by securing their own feet using the foot strap and heel block mechanism, eliminating the need for manual assistance from another person. The user can adjust and secure the foot strap themselves, enabling solo practice sessions.
Solution Approach 2:
The foot strap acts as an intermediary between the user's feet and the heel block, providing a mechanical means to secure the feet in place without requiring another person's hands. The heel block serves as a fixed reference point that works together with the adjustable strap to achieve stable foot positioning.
2Manufacturing precision
If a fixed foot holding device is used, then foot positioning consistency is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional components: a foot strap for securing, a heel block for positioning reference, and a non-slip backboard for stability. This segmentation allows each component to perform its specific function while keeping the overall device simple and easy to manufacture.
Solution Approach 2:
The foot strap is designed to be adjustable and dynamic, allowing users to customize the fit for different foot sizes and preferences. This dynamic element provides consistent foot positioning across different users without requiring a complex array of fixed-size holders.
3Adaptability or versatility
If additional features like cushioning pads and foldable legs are added, then user comfort and versatility are improved, but device weight and storage complexity increase
Solution Approach 1:
The legs are designed to be foldable and movable, allowing the device to transition between different configurations (inclined, declined, or flat positions) and a compact storage state. This dynamic design provides versatility without requiring permanent fixed structures.
Solution Approach 2:
The same leg mechanism serves multiple functions: providing structural support when unfolded, enabling position adjustment (incline/decline), and allowing compact storage when folded. The cushioning pad similarly provides both comfort during exercise and a non-slip surface during storage.
