Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel side apparatuses face issues with irregular deformation of wiring due to bending when the vehicle wheel is rotated with steering, leading to potential interference with surrounding components and reduced lifespan.
Innovation Solution
A vehicle wheel side apparatus with a configuration that includes a plurality of connection parts to keep wire-like transmission members straight, routed as close as possible to the steering rotation central axis, and supported by a support member to minimize deformation during steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wirings are bended and guided to the side of the in-wheel motor, then the wirings can be connected to the connector portion, but irregular deformation occurs in the wiring when the vehicle wheel is rotated with steering
Solution Approach 1:
The connector portion is positioned at the center of the in-wheel motor in the vehicle width direction, and multiple connector portions are arranged in the vehicle front-back direction. This spatial reconfiguration allows wirings to extend straight from the vehicle body along the vehicle front-back direction without bending, eliminating the deformation issue while maintaining connection functionality.
2Adaptability or versatility
If multiple connector portions are arranged along the vehicle width direction, then all connectors can be accessed, but excess portion occurs in the electrical wire and irregular deformation occurs
Solution Approach 1:
Instead of arranging multiple connector portions along the vehicle width direction, the invention positions connector portions at the center in the vehicle width direction and arranges them along the vehicle front-back direction. This dimensional change allows wirings to extend straight without excess portions or irregular deformations, while still providing multiple connection points for adaptability.
3Reliability
If wirings are routed straight from the vehicle body, then irregular deformation is reduced, but the wiring may not reach the connector portion at the side of the in-wheel motor
Solution Approach 1:
The invention positions connector portions at the center of the in-wheel motor in the vehicle width direction and arranges them along the vehicle front-back direction. This configuration allows wirings to extend straight from the vehicle body along the front-back direction, achieving both straight routing for reliability and adequate length to reach the connectors without bending.
