Cam Locking Assembly With Replaceable Wire Loop Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cam locking devices face difficulties in replacing the wire element, which is often made of textile material and has a shorter lifespan than the rest of the device, necessitating the entire device's replacement when the wire element is damaged or worn out, and the current methods for attaching the wire element to the head are complex and prone to durability issues.
Innovation Solution
A cam locking device design that allows for easy replacement of the wire element by detachable anchors and a tube system that facilitates separation of the head and stem assemblies, enabling the wire element to be easily attached and detached from the head, with a tube that prevents loop closure and ensures mechanical continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the wire element is permanently secured to the head using traditional methods (knots, splicing, crimping), then mechanical continuity is achieved, but replacement becomes difficult or impossible and the overall device complexity increases
Solution Approach 1:
The device is divided into separable components: the head assembly with anchor, the wire element with loop, and the stem assembly. This segmentation allows the wire element to be independently replaced without affecting the head or stem assemblies. The anchor and loop serve as interface elements that enable easy connection and disconnection.
Solution Approach 2:
The wire element is extracted as a separate, replaceable component from the traditional integrated design. By removing the wire element from permanent attachment to the head and stem, it becomes an independent serviceable part that can be replaced when worn, extending the overall device lifespan.
2Ease of operation
If the wire element is made of textile material to reduce weight and improve flexibility, then ease of operation is improved, but durability decreases and lifespan is shortened
Solution Approach 1:
The wire element is designed as a consumable component with有限 lifespan that can be discarded and replaced. The loop design allows the wire element to be easily removed and replaced without damaging other components, enabling recovery and reuse of the more durable head and stem assemblies.
3Reliability
If the wire element is permanently attached to ensure mechanical continuity, then reliability is improved, but ease of repair deteriorates as replacement requires disassembling the entire device
Solution Approach 1:
The anchor and loop serve as intermediary elements that provide mechanical continuity while enabling easy connection and disconnection. These intermediaries allow the wire element to be attached and detached without affecting the structural integrity of the head and stem assemblies during the attachment process.

AI summary
A cam-operated locking device comprising: a head subassembly (1) including a head (3) equipped with a cam (4) and a rod subassembly (2) having a rod (5) and at least one wire element (6). The wire element (6) passes through the rod (5). The rod (5) defines a through hole (8) for receiving a connector. The wire element (6) defines the through hole (8). The wire element (6) defines at least one loop (6a) that attaches to the head (3) to form mechanical continuity between the head (3) and the anchor point. At least one loop (6a) is traversed by a tube (7). The tube (7) and at least one loop (6a) are traversed by an anchor (9) fixed to the head (3) to form mechanical continuity between the head (3) and the anchor point.
