Solution Overview

Problem

Existing camming clamping devices do not allow for easy replacement of the wire element, which is often made of textile material and has a shorter lifespan than the head assembly, leading to the entire device needing replacement when the wire element is damaged or worn out.

Innovation Solution

The camming clamping device features a mechanical connection between the head and the annular end using a wire element that defines at least one loop, which is passed through by a tube and an anchorage fixed to the head, allowing for easy separation and replacement of the wire element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wire element is permanently fixed to the head assembly, then the structural integrity and reliability are improved, but the ease of repair deteriorates because the entire device must be replaced when the wire element is damaged

Engineering Contradiction:
Improvestructural integrityVSAvoidwire element replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The device is divided into separable components: the head assembly and the wire element. The wire element can be detached from the head assembly through a specific release mechanism, allowing the wire element to be replaced independently without replacing the entire device. This segmentation enables separate replacement of worn components while maintaining structural integrity during use.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the wire element is made from textile material, then the flexibility and ease of operation are improved, but the duration of action deteriorates because textile material ages much more quickly than metal components

Engineering Contradiction:
ImproveflexibilityVSAvoidwire element lifespan
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The wire element is designed as a consumable component that can be easily discarded and replaced. The head assembly incorporates a release mechanism that allows the wire element to be quickly removed and replaced without specialized tools or complex procedures. This enables users to replace aged textile wire elements before they fail, extending the overall device lifespan through component renewal.

Inventive Principle:
Principle #34Discarding and recovering

3Strength

If the wire element is permanently crimped or knotted to the head, then the strength of connection is improved, but the ease of manufacture and repair deteriorates due to the complexity of assembly and replacement procedures

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

An intermediary release mechanism is introduced between the wire element and the head assembly. This mechanism includes a release element that can selectively engage or disengage the wire element from the head. During normal use, the connection is strong and secure; when replacement is needed, the release element allows easy detachment without requiring cutting, untying, or complex disassembly procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A camming clamping device comprising: a head sub-assembly including a head provided with a cam and a rod sub-assembly having a rod and at least one wire element. The wire element passes through the rod. The rod delineates a through hole designed to receive a connector. The wire element delineates the through hole. The wire element defines at least one loop that is attached to head to constitute a mechanical continuity between the head and the attachment point. The at least one loop is passed through by a tube. The tube and the at least one loop are passed through by an anchorage fixed to the head to constitute the mechanical continuity between the head and the attachment point.
