Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex dismantling mechanism is used to ensure high holding force, then the holding reliability is improved, but the device complexity and bulkiness increase

Engineering Contradiction:
Improveholding reliabilityVSAvoiddismantling mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clip is divided into two toothed plates that can move independently relative to each other. The first plate remains stationary while the second plate can move away from the first during dismantling, allowing the holding function to be segmented and simplified without compromising reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection walls are designed with an inclination angle that allows the second plate to move dynamically away from the first plate when force is applied. This dynamic movement capability enables simple dismantling while maintaining strong holding force during normal operation

Inventive Principle:
Principle #15Dynamics

2Reliability

If a complex dismantling mechanism is used to ensure high holding force, then the holding reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveholding reliabilityVSAvoiddismantling ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The dismantling operation is simplified by segmenting the clip into movable and stationary parts. The second plate can be independently moved away from the first plate, allowing dismantling to be performed with simple manual force rather than complex mechanisms

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inclined connection walls create a dynamic mechanism where applying force to move the second plate away from the first automatically triggers the dismantling process, making operation effortless while maintaining high holding reliability

Inventive Principle:
Principle #15Dynamics

3Strength

If the clip structure is made rigid to maintain structural integrity, then the strength is improved, but the ease of operation deteriorates due to difficulty in separating plates

Engineering Contradiction:
Improvestructural integrityVSAvoidplate separation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The connection walls are designed with a specific inclination angle that creates a dynamic response: under normal conditions the structure maintains rigidity and strength, but when force is applied to separate the plates, the inclined walls allow controlled movement and separation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clip structure is segmented into plates connected by inclined walls, allowing the overall structure to maintain integrity while enabling localized movement during separation. The segmented design allows force to be applied efficiently to separate plates without compromising overall structural strength

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The clip achieves efficient and effortless removal with minimal effort, utilizing a simple force application to disengage the toothed plates from the threaded member, maintaining structural integrity during assembly and disassembly.

AI summary

This document relates to a clip, in particular for securing objects such as pipes or cables (11) to a support structure (5) by means of a threaded element (3) such as a threaded stud or a screw. The clip comprises a clip body (13) for mounting it onto the threaded element, which includes two parallel rigid walls (26) spaced apart by a distance corresponding to the diameter of the threaded object and provided on their opposite faces with teeth (29) that grip the threads of said element when it is engaged between the two walls. These teeth are connected to the body by retaining walls (31) adapted to allow the toothed walls to move elastically apart when the threaded element is engaged between these walls. The clip also includes a device for removing the clip from the threaded element.The clip is characterized in that the dismantling device is formed by means (35) for separating the toothed walls 26 into a position in which the teeth (29) no longer grip the threads of the threaded member (3), which are actuated from the outside. The invention is applicable for securing pipes or cables.
