Rotating Wire Guide Cover for Exercise Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise equipment designs face challenges in ensuring smooth wire movement and preventing foreign substance infiltration through wire outlets, as well as minimizing the risk of wire entanglement, which affects durability and user experience.
Innovation Solution
The exercise equipment incorporates a wire guide system with a rotating cover body and pulleys to guide the wire, a limiter to prevent excessive rotation, and a restoring force mechanism to maintain the cover body's initial position, ensuring smooth wire movement and minimizing foreign substance infiltration and entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wire outlet is provided for wire entry and exit, then wire movement is enabled, but foreign substances may be introduced through the outlet
Solution Approach 1:
A flexible cover body is provided that can rotate to cover the wire outlet. The cover body acts as a flexible barrier that prevents foreign substances from entering through the outlet while still allowing the wire to pass through. The cover body includes a through-hole that guides the wire, and its rotational movement enables it to open when the wire needs to move and close when not in use, thus blocking foreign substances.
2Ease of operation
If the wire outlet is open for wire movement, then wire accessibility is improved, but the risk of wire entanglement increases
Solution Approach 1:
The cover body is designed to be rotatable about an axis, transitioning between open and closed positions. When the wire needs to be accessed or moved, the cover body rotates to an open position, allowing full accessibility. When not in use, the cover body rotates to a closed position that guides the wire through a designated path, preventing random movement and entanglement. This dynamic positioning resolves the contradiction between accessibility and entanglement prevention.
3Object-affected harmful factors
If a cover body is added to protect the wire outlet, then foreign substance infiltration is reduced, but device complexity increases
Solution Approach 1:
The cover body serves multiple functions simultaneously: (1) It acts as a protective barrier to prevent foreign substances from entering through the wire outlet; (2) It provides a guide path for the wire through its through-hole; (3) It can rotate to open/close the outlet as needed; (4) It structurally integrates with the body housing. By combining these multiple functions into a single component, the design reduces overall complexity compared to having separate protective covers, guides, and locking mechanisms.
