Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing binding structures for wire routing materials in vehicles are costly and difficult to assemble due to the large size of guide members required for different wire routing materials, such as wire harnesses and flat wire routing materials.

Innovation Solution

A binding structure comprising a flexible wire routing material, a plate-shaped flat wire routing material, and an engaging member with a binding portion that encloses both materials in a short interval, using an engaging portion that protrudes from the flat wire routing material side for stability and assembly, allowing for a smaller engaging member that facilitates easier assembly into the vehicle body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a guide member with two recessed storage portions is used to bind wire harness and flat wire routing material separately, then both materials can be bound together, but the guide member becomes large in size and costly

Engineering Contradiction:

Improveability to bind different wire routing materialsVSAvoidsize of guide member

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The guide member is divided into two separate components: a first engaging member for the wire harness and a second engaging member for the flat wire routing material. This segmentation allows each component to be compact and optimized for its specific function, eliminating the need for a large integrated guide member with multiple recesses.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first and second engaging members are combined through engagement between them, creating a unified binding structure that secures both wire harness and flat wire routing material. This merging achieves the versatility of binding different materials while maintaining compact individual component sizes.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If a large guide member is used to accommodate different wire routing materials, then binding is achieved, but assembly into vehicle body becomes difficult

Engineering Contradiction:

Improvebinding capability for different materialsVSAvoidassembly workability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By segmenting the guide member into smaller first and second engaging members, each component becomes easier to handle and assemble individually. The smaller size and simpler structure of each engaging member improve assembly workability compared to a single large guide member.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The engaging members are designed with flexible binding portions that can adapt to different wire routing materials dynamically. This flexibility allows the components to be easily assembled and adjusted during installation while maintaining secure binding of various material types.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If flexible wire routing material is bound alone, then it can be secured, but it deforms and binding becomes unstable

Engineering Contradiction:

Improvebinding capabilityVSAvoidbinding stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The first engaging member (for wire harness) and second engaging member (for flat wire routing material) are merged together through their engagement interface. This combined structure provides mutual support and stabilization, preventing deformation of the flexible wire harness while maintaining secure binding.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The second engaging member acts as an intermediary that provides structural support to the flexible wire harness bound by the first engaging member. This intermediary component stabilizes the flexible material by distributing binding forces and preventing localized deformation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Provided is a binding structure of a wire routing material which can allow reduction of cost and also provides excellent workability for assembly into a vehicle body when wiring for wire routing materials having different shapes, such as a wire harness and a flat wire routing material, is performed in the vehicle body. A binding structure 1 is formed in which a flexible wire routing material 2 and a plate-shaped flat wire routing material 3 having higher rigidity than the flexible wire routing material 2 overlap each other, and the flexible wire routing material 2 and the flat wire routing material 3 are enclosed in an annular form, bound, and held by a binding portion 45 of an engaging member 4 including an engaging portion 40 for assembly into the vehicle body.
