Solution Overview

Problem

Existing wire covers do not allow for visual confirmation of the depth of insertion of a corrugate tube, leading to potential misalignment and insufficient holding force, as they lack features for clear visual inspection and fluid drainage.

Innovation Solution

A wire cover design with through holes in the tube holder for visual confirmation of tube alignment and fluid drainage, featuring fitting projections and recesses that engage with the corrugate tube's ribs and grooves, ensuring proper engagement and preventing fluid accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the wire cover is designed without through holes, then the structure remains simple and intact, but visual confirmation of tube insertion depth becomes impossible and fluid accumulates inside

Engineering Contradiction:
Improvevisual confirmation of tube insertion depthVSAvoidstructure of wire cover
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The wire cover incorporates through holes in the tube holder, transforming it from a solid structure to a porous one. These holes enable visual confirmation of tube insertion depth by allowing operators to see through the tube holder to the corrugate tube, while also providing fluid drainage pathways to prevent water accumulation inside the wire cover.

Inventive Principle:
Principle #31Porous materials

2Object-generated harmful factors

If the wire cover lacks fluid drainage pathways, then the structure remains sealed and intact, but fluid accumulates inside causing potential damage

Engineering Contradiction:
Improvefluid accumulation inside wire coverVSAvoidstructure of wire cover
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The through holes create a porous structure in the tube holder that serves dual purposes: enabling visual inspection and providing fluid drainage. The holes allow water to pass through from the interior to the exterior, eliminating fluid accumulation hazards without requiring separate drainage components.

Inventive Principle:
Principle #31Porous materials

3Manufacturing precision

If the corrugate tube is held without visual confirmation, then the assembly process is faster, but misalignment and insufficient holding force occur

Engineering Contradiction:
Improvealignment of corrugate tubeVSAvoidassembly speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The through holes provide visual feedback during the assembly process. Operators can see through the tube holder to monitor the insertion depth and alignment of the corrugate tube in real-time, allowing for immediate detection and correction of misalignment issues without requiring disassembly or additional measurement tools.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The invention utilizes visual transparency (an optical property) to provide feedback. The through holes allow light to pass through, enabling operators to visually detect the position and alignment of the corrugate tube relative to the tube holder, ensuring precise assembly.

Inventive Principle:
Principle #32Color changes

AI summary

A wire cover is provided for enabling a held state of a corrugate tube to be confirmed visually. Since tube holders (19) into which a front end portion of the corrugate tube (30) is fitted are formed with through holes (23A, 23B) and (23C) penetrating from the outer circumferential surface to the inner circumferential surface, a held state of the corrugate tube (30) fitted in the tube holders (19) of the wire cover (10) can be confirmed by the eyes through the through holes (23A, 23B) and (23C). Further, since water inside the wire cover (10) is drained out through the through holes (23A, 23B) and (23C), water is unlikely to stay inside the wire cover (10).
