Solution Overview

Problem

Conventional electric wire fixing devices and wire harnesses face difficulties in smooth routing and fixing due to misalignment of the fixing member with the fixing face, leading to inefficient wire routing work.

Innovation Solution

An electric wire fixing device with a protector that allows a fixing member to make sliding and rotational movements, featuring a movement restriction part to ensure proper alignment and attachment to a vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the fixing member is allowed to make sliding movement against the exterior protection tube to be disposed at a prescribed position, then the fixing member can be positioned correctly, but the posture or angle of the fixing member may not match the fixing face, causing fixing work to not be performed smoothly

Engineering Contradiction:
Improvepositioning accuracyVSAvoidfixing work smoothness
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The fixing member is designed to be rotatable relative to the exterior protection tube, allowing dynamic adjustment of its posture and angle. This rotational freedom enables the fixing member to adapt its orientation to match the fixing face, resolving the contradiction between precise positioning and operational smoothness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention adds a rotational degree of freedom (angular dimension) to the fixing member's movement capabilities. While sliding movement provides linear positioning adjustment, the added rotational capability allows the fixing member to adjust its posture in a different dimension, enabling it to match the fixing face orientation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the fixing member is constrained to a fixed position, then the structure is simple, but it cannot absorb dimensional tolerances and adapt to misalignments

Engineering Contradiction:
Improvestructure simplicityVSAvoidtolerance absorption capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The fixing member is designed with rotational freedom relative to the exterior protection tube, transforming it from a static fixed-position component to a dynamic adjustable component. This allows the structure to absorb dimensional tolerances and adapt to misalignments while maintaining relative structural simplicity through the use of a straightforward rotational mechanism.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the fixing member is allowed to rotate freely, then it can adapt to various angles, but the moving area is not restricted causing potential instability

Engineering Contradiction:
Improveangle adaptation capabilityVSAvoidfixing member stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The exterior protection tube is designed with a localized engagement structure that provides rotational freedom within a controlled range. This local quality change allows the fixing member to adapt to various angles while the engagement structure maintains stability by preventing excessive or uncontrolled rotation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention changes the rotational parameter from completely free rotation to controlled rotation within a specific range. The engagement structure between the fixing member and exterior protection tube defines acceptable angular parameters, allowing adaptability to various installation angles while maintaining stability through parameter constraints.

Inventive Principle:
Principle #35Parameter changes

AI summary

An electric wire fixing device includes: a protector attached to the outer periphery of a bending tube and a straight tube that house an electric wire; and a clamp configured to be fixed to a vehicle, the clamp being attached to the protector in a manner of being allowed to make a sliding movement in an extending direction of the electric wire and make a rotational movement about the extending direction. The protector includes a movement restriction part that restricts a moving area of the sliding movement of the clamp.
