Wiring Member Attachment Structure for Easy Clamp Detachment

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing clamp designs, such as those described in Patent Document 1, face difficulties in detaching the wiring member from the attaching target member due to the elastic deformation of the first locking part, making it hard to remove the wiring member during repairs.

Innovation Solution

The proposed attachment structure includes a convex-shaped part and a concave-shaped part with an elastic deformation part, allowing for easy insertion and detachment by elastically deforming the parts in a similar manner when force is applied in opposite directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the first locking part is designed to be elastically deformed in a spreading direction when force is applied to lock to the attaching hole, then the clamp is securely locked and hard to pull out, but the wiring member becomes hard to detach from the attaching target member

Engineering Contradiction:

Improvelocking reliabilityVSAvoiddetachability

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The patent applies the inversion principle by designing the elastic deformation part to deform in the same direction (narrowing direction) during both attachment and detachment operations. Conventionally, locking mechanisms deform in opposite directions for locking versus releasing, but this patent makes the deformation direction consistent, allowing the same elastic structure to facilitate both secure locking and easy detachment by pulling the wiring member in the same direction used for attachment

Inventive Principle:

Principle #13The other way round (Inversion)

2Strength

If the elastic deformation part deforms in the spreading direction during attachment, then the convex-shaped part fits securely into the concave-shaped part, but the same deformation mechanism prevents easy removal

Engineering Contradiction:

Improvefitting strengthVSAvoiddetachment ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent reverses the conventional approach by making the elastic deformation direction consistent for both attachment and detachment. The elastic deformation part narrows in the same direction during both operations, allowing the fitting strength to be maintained while enabling easy detachment through the same pulling motion used for attachment

Inventive Principle:

Principle #13The other way round (Inversion)

3Stability of the object's composition

If the clamp structure uses elastic deformation for secure locking, then the connection is strong and stable, but the wiring member cannot be easily removed for repairs

Engineering Contradiction:

Improveconnection stabilityVSAvoidwiring member removability

Core Design Contradiction:

Stability of the object's compositionVSEase of repair

Solution Approach 1:

The patent applies inversion by making the elastic deformation direction consistent for both attachment and detachment operations. The elastic deformation part narrows during both locking and releasing, allowing the connection to remain stable during normal operation while enabling easy removal for repairs by simply pulling the wiring member in the same direction used for attachment

Inventive Principle:

Principle #13The other way round (Inversion)

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

This solution enables easy detachment of the wiring member from the attaching target member, facilitating repairs while maintaining a secure attachment during normal operation.

Implementation Method 1

an elastic deformation part is formed in at least one of the convex-shaped part and the concave-shaped part, and when the convex-shaped part is inserted into the concave-shaped part upon receiving force toward a first direction, the elastic deformation part is elastically deformed by the force toward the first direction to fit the convex-shaped part to the concave-shaped part

Methodology Applied

Scientific EffectElastic deformation: Elasticity

Implementation Method 2

when the convex-shaped part is pulled from the concave-shaped part upon receiving force toward a second direction opposite to the first direction, the elastic deformation part is elastically deformed by the force toward the second direction in a direction similar to the case of receiving the force toward the first direction, and releases a fitting state of the convex-shaped part and the concave-shaped part

Methodology Applied

Scientific EffectElastic deformation: Elasticity

AI summary

A wiring member includes a base member, a wire-like transmission member fixed to the base member, and a plurality of attaching members provided to the base member to be attached to an attaching target member. One attaching member is provided to only one lateral side of the wire-like transmission member in a first position along an extension direction of the wire-like transmission member in the base member. Another attaching member is provided to only another lateral side of the wire-like transmission member in a second position along the extension direction of the wire-like transmission member.
