Slidable Wire Routing Binding Structure for Vehicle Assembly

Solution Overview

Problem

Conventional engaging members face difficulties in attaching to flat wire routing materials due to their rigidity, leading to impaired assembly efficiency and potential misalignment, as they cannot absorb positional displacement like flexible wire harnesses can.

Innovation Solution

A binding structure for wire routing materials that includes a slidable engaging member with movement restricting portions, allowing it to be securely attached and limiting its movement range within a predetermined area, using binding members to enclose and bind the wire routing material, thereby facilitating assembly into vehicle body fixing holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a flat wire routing material with high rigidity is used, then the wire routing material can provide stable power supply, but the engaging member cannot absorb positional displacement and assembly efficiency is impaired

Engineering Contradiction:

Improvestability of power supplyVSAvoidassembly efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The engaging member is designed with movability relative to the wire routing material, allowing it to slide within a predetermined range. This dynamic capability enables the engaging member to absorb positional displacements during assembly while maintaining stable attachment, thereby resolving the contradiction between rigidity-based stability and assembly efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The binding member serves as an intermediary that secures the engaging member to the wire routing material while permitting controlled movement. This intermediary structure enables both the stability provided by rigid attachment and the flexibility needed for assembly tolerance adjustment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the engaging member is made movable relative to the wire routing material, then the engaging portion can be assuredly inserted into the fixing hole, but significant displacement occurs causing difficulty in assembly

Engineering Contradiction:

Improveease of insertion into fixing holeVSAvoidpositioning precision of engaging portion

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The engaging member is designed with movability relative to the wire routing material, allowing it to slide within a predetermined range. This dynamic capability enables the engaging member to absorb positional displacements during assembly while maintaining stable attachment, thereby resolving the contradiction between rigidity-based stability and assembly efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent defines specific parameters for the movement range of the engaging member, constraining it within predetermined limits. By controlling the extent of movement rather than eliminating it entirely, the system maintains ease of insertion while preventing excessive displacement that would compromise assembly precision.

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If the engaging member is strictly positioned on the wire routing material, then the engaging portion can be inserted into the fixing hole, but the attachment position needs strict management reducing work efficiency

Engineering Contradiction:

Improvepositioning precision of engaging memberVSAvoidwork efficiency of attaching engaging member

Core Design Contradiction:

Manufacturing precisionVSProductivity

AI summary

Elongated wire routing materials are bound by a first-side binding member on a first side in the longitudinal direction of the wire routing materials, and are bound by a second-side binding member on a second side opposite to the first side. An engaging member includes an engaging portion for assembly into a vehicle body, and an attachment portion serving as the part to which the wire routing materials are attached such that the attachment portion is slidable relative to the wire routing materials in the longitudinal direction. At least one of the engaging portion and the attachment portion comes into contact with the first-side binding member at the first side, and at least one of the engaging portion and the attachment portion comes into contact with the second-side binding member at the second side.
