Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing through lamps for vehicles are heavy, requiring strong mounting to sheet metal members, limiting installation positions and posing higher harm in collisions due to their weight and structural strength needs.
Innovation Solution
A through lamp design featuring an exterior trim panel with a light-transmitting area, a mounting bracket, and a light-emitting assembly within a lamp chamber, allowing for flexible mounting and reduced weight, eliminating the need for high-strength connectors and minimizing harm in collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional through lamps are used with heavy construction, then structural strength is improved, but weight increases and mounting flexibility decreases
Solution Approach 1:
The through lamp is divided into separate functional modules: light-emitting assemblies, mounting brackets, and exterior trim panels. This segmentation allows each component to be optimized independently, reducing overall weight while maintaining structural integrity where needed.
Solution Approach 2:
The patent changes the physical parameters of the lamp structure by using lighter materials and optimizing the geometric parameters of mounting brackets and support structures, achieving reduced weight while maintaining adequate strength through parameter optimization rather than mass increase.
2Stability of the object's composition
If heavy through lamps are mounted to sheet metal members, then mounting stability is improved, but installation position flexibility decreases
Solution Approach 1:
Mounting brackets serve as intermediary components between the light-emitting assemblies and the vehicle body. These brackets provide stable mounting while being lightweight enough to allow installation at multiple positions, acting as a mediator that balances stability requirements with installation flexibility.
Solution Approach 2:
The mounting brackets are designed with multi-functionality, serving both as structural support elements and as flexible mounting interfaces that can accommodate different installation positions. This universal design allows the same component to provide stable mounting across various locations on the vehicle.
3Strength
If high-strength connectors are used for mounting, then structural integrity is improved, but harm to pedestrians in collisions increases
Solution Approach 1:
The patent employs mounting solutions that prioritize pedestrian safety over permanent structural integrity. The mounting components are designed to be sufficient for normal operation but capable of failing safely during collisions, protecting pedestrians by reducing rigid, high-strength connections that could cause injury.
Solution Approach 2:
The design converts the potential harm of strong mounting structures into a benefit by intentionally designing mounting systems that balance structural integrity with safety. The mounting strength is optimized to provide adequate support during normal use while allowing controlled failure modes during collisions, turning what would be a harmful rigid connection into a safety feature.

AI summary
A through lamp for a vehicle includes an exterior trim panel provided with a light-transmitting area; a mounting bracket arranged on an inner surface of the exterior trim panel, a lamp chamber being defined between the mounting bracket and the inner surface of the exterior trim panel; and a light-emitting assembly arranged in the lamp chamber. Light emitted by the light-emitting assembly is emitted outwards through the light-emitting area.
