Steering Wheel Lighting Assembly With Integrated Bezel and Wire Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices for steering wheels have complex assembly processes and a large number of components, leading to reduced mass productivity due to their intricate structures.
Innovation Solution
A simplified assembly structure for a lighting device on a steering wheel, featuring a grip body with a body groove, a bezel with a light transmission hole, and a light emitting body assembled between the bezel and grip body, along with a wire groove for easy wire insertion, and a wheel cover for improved gripping sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional lighting device structure is used, then the indicator function can be performed, but the number of components is large and the assembly process is complicated, reducing mass productivity
Solution Approach 1:
The patent merges multiple components into a unified assembly structure. The bezel is integrated with the grip body through the body groove portion, and the light emitting body is assembled into the bezel's light transmission hole, creating a compact integrated unit that reduces the number of separate components and simplifies the assembly process while maintaining the indicator function
Solution Approach 2:
The lighting device is segmented into distinct functional modules: the grip body with body groove portion, the bezel with light transmission hole, and the light emitting body. This modular segmentation allows for simplified assembly where each module can be independently manufactured and then easily combined, improving mass productivity while maintaining functionality
2Reliability
If multiple components are used to ensure light transmission and structural integrity, then the indicator function is reliable, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The bezel is pre-formed with a light transmission hole and assembly groove, and the grip body is pre-formed with a body groove portion. These preliminary structural preparations allow the light emitting body to be quickly assembled into the predetermined position without requiring complex assembly steps, thereby reducing assembly time while ensuring reliable light transmission and structural integrity
