Door Wiring Module With Deformable Protective Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The position of a grommet attached to a door panel can vary by vehicle model and grade, requiring redesign of the wiring member extending from the grommet, which limits the versatility of the wiring module.
Innovation Solution
A wiring module with a grommet that includes a base portion fixed to the door panel and a wiring member with a first section covered by a protective portion capable of bending or stretching deformation, allowing the module to accommodate changes in grommet position without redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the grommet position is changed to accommodate different vehicle models and grades, then the versatility of the wiring module is improved, but the wiring member structure must be redesigned which increases device complexity
Solution Approach 1:
The protective portion is designed with dynamic characteristics, being capable of bending deformation and stretching deformation. This allows the wiring member to adapt to different grommet positions without requiring rigid structural redesigns for each vehicle configuration, thus improving versatility while maintaining structural simplicity
Solution Approach 2:
The protective portion's physical parameters (shape, length) can change through bending and stretching deformations. This parameter variability enables the same wiring member structure to accommodate different grommet positions across various vehicle models and grades without redesign
2Reliability
If the wiring member is made rigid to maintain structural stability, then the reliability is improved, but the ability to accommodate position changes is reduced
Solution Approach 1:
The wiring member exhibits local quality differentiation: the protective portion has flexible properties (capable of bending and stretching) while other portions maintain rigidity. This localized flexibility allows the structure to adapt to position changes without compromising overall structural stability and reliability
Solution Approach 2:
The wiring member is segmented into different functional portions with distinct properties. The protective portion is separated as a distinct segment with deformation capabilities, while other segments maintain structural integrity. This segmentation allows simultaneous achievement of reliability and adaptability

AI summary
One object is to provide a technology that can increase the versatility of a wiring module in which a grommet is provided in a wiring member. The wiring module includes a wiring member connecting a vehicle body and a door panel, and a grommet attached to the wiring member. The grommet includes a base portion fixed at a certain position with respect to the door panel. The wiring member includes a first section and a second section that is located on the vehicle body side relative to the first section and is covered by the base portion. The first section of the wiring member is covered by a protective portion capable of at least one of bending deformation and stretching deformation.
