Through-Type Vehicle Lamp Continuous Coupling for Uniform Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Through-type vehicle lamps face stability issues due to traditional installation methods using multiple snaps, leading to poor coupling stability and visible bright spots during lighting.
Innovation Solution
A through-type lamp design featuring a housing with a continuous slot and an outer cover with a continuous protrusion that clamps together, enhancing coupling stability through increased contact area and using fasteners or structural adhesives, along with a light guide structure and decorative frames to improve lighting uniformity and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multiple snaps are used for installation, then the installation method is simple, but the coupling stability is poor
Solution Approach 1:
The patent merges multiple discrete snap fasteners into a single continuous slot-protrusion coupling structure. The slot extends along the housing and the protrusion extends along the outer cover, creating a continuous mechanical interlock that replaces multiple separate connection points, thereby improving coupling stability while simplifying the overall structure.
Solution Approach 2:
The patent transitions from point-based snap connections to a line-based continuous slot-protrusion interface. By extending the coupling structure along the length of the lamp housing and outer cover, the connection is distributed across a continuous dimension rather than concentrated at discrete points, enhancing stability.
2Illumination intensity
If traditional installation methods are used, then the manufacturing process is simple, but visible bright spots appear during lighting
Solution Approach 1:
The continuous slot and protrusion design merges multiple discrete installation points into a unified structure, eliminating the gaps and discontinuities that cause bright spots. This creates a seamless interface between housing and outer cover, ensuring uniform light distribution across the lamp surface.
3Area of stationary object
If multiple snaps are used for coupling, then the structure is easy to manufacture, but the contact area is insufficient
Solution Approach 1:
The patent extends the coupling interface from zero-dimensional point contacts (snaps) to one-dimensional continuous lines (slot and protrusion). This dimensional transformation dramatically increases the contact area between housing and outer cover, distributing mechanical stress across a larger surface while maintaining structural integrity.

AI summary
A lamp includes a housing, an outer surface cover, and a light guide structure. The housing and the outer surface cover define a light chamber. The light guide structure further includes a light source, an inner cover and a reflector, the reflector is coupled to the housing and configured to reflect the light emitted from the light source to the inner cover, and emit the light through the inner cover and the thick wall in sequence.
