Vehicle Tail Lamp Depth Reduction via LED Board Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tail lamp structures for vehicles face challenges in miniaturization, particularly in reducing depth to accommodate rear wheels effectively, and they often require additional components and complex designs, leading to increased part counts and reduced flexibility in design.
Innovation Solution
The proposed solution involves arranging the control element board either upwardly or downwardly of the light-emitting diode board within a housing, with a lens covering the housing, and using a mud guard cover to conceal the control element board, while extending the harness from the side of the housing to reduce depth and secure space for the rear wheel, incorporating an inner lens and light-shielding panel for improved visibility and design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control element board is arranged separately from the light-emitting diode board, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The control element board is integrated with the light-emitting diode board into a single unified board structure. The control elements are mounted on the same substrate as the light-emitting diodes, eliminating the need for separate control boards and reducing the overall number of components while maintaining full functionality.
2Object-affected harmful factors
If the tail lamp structure includes separate tail cover for covering upper portions, then the protection is improved, but the number of parts increases
Solution Approach 1:
The housing structure is designed to integrate the functions previously requiring separate tail covers. The housing itself is configured to protect the upper portions of the tail lamp assembly, eliminating the need for additional tail cover components while maintaining protective functionality.
3Ease of manufacture
If the control element board is arranged in the conventional position, then the assembly is straightforward, but the depth of the tail lamp increases
Solution Approach 1:
The control element board is arranged in the same plane as the light-emitting diode board rather than being positioned in a separate depth layer. This two-dimensional layout optimization allows all components to be mounted on the front surface of the housing, minimizing the depth of the tail lamp assembly.
