Rotatable Vehicle Light Projector for Multi-Model Light Bar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light assemblies require a different manufacturing setup for each vehicle make and model to accommodate varying projector orientations relative to the end cap of the light bar, leading to inefficiencies and increased costs.
Innovation Solution
A vehicle light assembly design that includes a rotatable projector connected to a light bar, allowing the projector to be axially movable between two positions, with the ability to rotate relative to the end cap when in the second position, and a wiring system that accommodates this movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a different light assembly is manufactured for each different vehicle make and model to control the orientation of the projector relative to the end cap of the light bar, then the projector orientation can be precisely controlled for each vehicle, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The projector is made rotatable relative to the end cap of the light bar, allowing dynamic adjustment of the projector's orientation after assembly. This enables a single light assembly design to be adapted to different vehicle makes and models without requiring different manufacturing setups, thus resolving the contradiction between manufacturing precision and device complexity.
2Manufacturing precision
If a different light assembly is manufactured for each different vehicle make and model, then the specific orientation requirements for each vehicle can be met, but the manufacturing cost and time increase
Solution Approach 1:
The light bar assembly is designed as a universal component that can be installed on various vehicle makes and models. The projector's rotatable connection to the end cap allows a single universal light bar assembly to serve multiple vehicle applications, eliminating the need for different manufacturing setups for each vehicle type and thereby improving manufacturing efficiency.
3Ease of manufacture
If the projector is fixed relative to the end cap of the light bar, then the manufacturing process is simpler, but the light assembly cannot be adapted to different vehicle makes and models
Solution Approach 1:
The projector is connected to the end cap through a rotatable joint rather than a fixed connection. This dynamic connection allows the projector to be oriented at different angles after assembly, enabling the same light bar assembly to be adapted to different vehicle makes and models while maintaining a simple and consistent manufacturing process.
