Door Wiring Module Assembly With Easy-Bending Connection Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing door wiring modules face challenges in assemblability, particularly when integrating outer and inner side regulation route portions, which require improved routing and fixation mechanisms to enhance assembly efficiency.
Innovation Solution
The proposed door wiring module incorporates an outer side regulation route portion between the outer and inner panels, an inner side regulation route portion closer to the vehicle interior, and a connection route portion with an easy-bending part to facilitate assembly. This design utilizes route regulation members and an adhesive layer to secure the wiring module to the door panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the outer side regulation route portion and inner side regulation route portion are modularized separately, then the routing organization is improved, but the assemblability deteriorates due to difficulty in assembling the outer side regulation route portion through the service hole
Solution Approach 1:
The wiring module is divided into three distinct portions: outer side regulation route portion, inner side regulation route portion, and connection route portion. This segmentation allows each portion to be optimized independently for its specific function while maintaining overall organizational stability.
Solution Approach 2:
The connection route portion is designed with different physical parameters compared to the regulation route portions. It lacks the rigid route regulation members and has greater flexibility, allowing it to be easily disposed of through the service hole during assembly while the regulation portions maintain their structured routing.
2Manufacturing precision
If the outer side regulation route portion is disposed between the outer panel and inner panel with route regulation, then the routing precision is improved, but the assembly complexity increases due to additional route regulation members
Solution Approach 1:
The wiring module is divided into three distinct portions: outer side regulation route portion, inner side regulation route portion, and connection route portion. This segmentation allows each portion to be optimized independently for its specific function while maintaining overall organizational stability.
Solution Approach 2:
Different portions of the wiring module have different local qualities: the regulation route portions have rigid structure with route regulation members for precision routing, while the connection route portion has flexible structure without regulation members for easy assembly. Each portion's structure is optimized for its specific functional requirements.

AI summary
A door wiring module includes a plurality of wiring members and an inner side route regulation member and an outer side route regulation member regulating routes of the plurality of wiring members. The plurality of wiring members include: an outer side regulation route portion disposed between the outer panel and the inner panel so that a route of the outer side regulation route portion is regulated by the outer side route regulation member; an inner side regulation route portion disposed closer to an inner side of a vehicle interior than the outer side regulation route portion so that a route of the inner side regulation route portion is regulated by the inner side route regulation member; and a connection route portion between the inner side regulation route portion and the outer side regulation route portion. The connection route portion includes an easy-bending part bended more easily than the outer side regulation route portion.
