Solution Overview

Problem

Existing door wiring modules require multiple part numbers to accommodate different door specifications, leading to increased costs due to the need for component changes.

Innovation Solution

A door wiring module with a service hole cover featuring a route indication part that allows the wiring member to pass through multiple routes of varying lengths, enabling the use of common components across different door specifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple part numbers are used to accommodate different door specifications, then the wiring module can be adapted to various door types, but the component cost increases

Engineering Contradiction:

Improveadaptability to different door specificationsVSAvoidcomponent cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The service hole cover is designed with multiple through-holes that can accommodate wiring members of different lengths and routing requirements. This universal design allows a single cover part to serve multiple door specifications without requiring different part numbers, thereby reducing component costs while maintaining adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cover body is segmented with multiple through-holes positioned at different locations, allowing the wiring member to be routed through different holes depending on the door specification. This segmentation enables a single component to accommodate multiple wiring routes and lengths, resolving the contradiction between adaptability and manufacturing cost.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If component changes are made for each part number, then the wiring module can precisely fit different door specifications, but the manufacturing complexity and cost increase

Engineering Contradiction:

Improvefit precision for different door specificationsVSAvoidcomponent variety

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The service hole cover is designed as a universal component with multiple through-holes that can accommodate wiring members for different door specifications. This eliminates the need for multiple specialized cover parts, reducing device complexity while maintaining the ability to precisely fit different door types by selecting appropriate through-holes for wiring routing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A door wiring module includes: a service hole cover including a cover body part and a route indication part provided to the cover body part; and a wiring member whose route is regulated so that the wiring member passes through a first position and a second position on the cover body part. The route indication part indicates a plurality of routes each having a route length different from each other as routes of the wiring member between the first position and the second position, and a route of the wiring member is regulated so that the wiring member passes through any route selected from the plurality of routes.
