Vehicle Wiring Module Layout for Flexible Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for increased design flexibility in arranging devices between a vehicle body panel and an interior member, such as the ceiling and roof liner, to accommodate changes in device position, specification, and number.
Innovation Solution
A wiring module is introduced, comprising devices, transmission members, and a rigid member with panel and device fixing portions, allowing for flexible attachment and support to a vehicle body panel, enabling changes in device position, specification, and number, while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are disposed in an arrangement space between a vehicle body panel and an interior member, then design flexibility is improved, but device stability and support are worsened due to limited space and lack of secure mounting structure
Solution Approach 1:
The rigid member is divided into multiple device fixing portions, each capable of independently securing a device. This segmentation allows flexible arrangement of devices while maintaining stable mounting through multiple discrete attachment points on the same rigid structure.
Solution Approach 2:
The transmission member is held by the rigid member, creating a nested structure where the transmission member is contained within the structure provided by the rigid member. This nesting provides stable support for the transmission member while allowing design flexibility in routing and positioning.
2Adaptability or versatility
If multiple devices are mounted on a rigid member with multiple device fixing portions, then adaptability is improved, but structural complexity is worsened
Solution Approach 1:
The rigid member serves multiple functions: it provides structural support, contains multiple device fixing portions for mounting various devices, and holds the transmission member. This multi-functionality increases adaptability while avoiding the need for separate components for each function, thereby limiting the increase in overall structural complexity.
3Reliability
If the wiring module is fixed to the vehicle body panel via the panel fixing portion, then mounting stability is improved, but ease of installation is worsened due to rigid structure
Solution Approach 1:
The rigid member is segmented with distinct panel fixing portion and device fixing portions, allowing the panel mounting function to be separated from device mounting functions. This segmentation enables stable fixed mounting to the vehicle body panel while maintaining ease of installation for the devices themselves through the separate device fixing portions.

AI summary
A wiring module disposed in a vehicle in an arrangement space between a vehicle body panel and an interior member includes at least one device; a transmission member extending from each one of the at least one device; and a rigid member including a panel fixing portion and a plurality of device fixing portions. Each one of the at least one device is fixed to a device fixing portion selected from the plurality of device fixing portions, and a portion of the transmission member extending out from each one of the at least one device is held by the rigid member. The wiring module is fixed to the vehicle body panel via the panel fixing portion.
