Through-type Lamp Slot-Protrusion Coupling Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Through-type vehicle lamps suffer from poor stability and uneven lighting due to traditional installation methods using multiple snaps, leading to granular sensations and bright spots.
Innovation Solution
A through-type lamp design featuring a housing with continuous slots and an outer cover with protrusions that increase contact area, coupled by fasteners or adhesive, along with a light guide structure and continuous light chamber for uniform lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multiple snaps installation method is used, then the housing and outer cover can be connected, but the contact area is small leading to poor stability and granular sensations
Solution Approach 1:
The patent transforms the connection interface from discrete point contacts (multiple snaps) to a continuous linear contact along the extension direction Y. The slot extending along the extension direction creates a dimensional transition from 0D point contacts to 1D line contact, significantly increasing the contact area and eliminating granular sensations while improving coupling stability.
Solution Approach 2:
The patent merges multiple discrete snap connection points into a single continuous slot-protrusion interface. By combining the functions of multiple snaps into one continuous connection structure, the design achieves both structural simplicity and enhanced stability through increased contact area along the extension direction.
2Illumination intensity
If traditional installation method is used, then assembly is simple, but lighting becomes uneven with bright spots and granular sensations
Solution Approach 1:
The continuous slot and protrusion design creates a uniform light distribution channel along the extension direction, transforming discrete light sources into a continuous lighting effect. This dimensional transition ensures even illumination without bright spots while maintaining structural simplicity suitable for through-type lamp applications.
3Reliability
If continuous slot and protrusion design is used, then contact area increases and stability improves, but manufacturing complexity increases
Solution Approach 1:
The patent segments the connection function into two distinct components: a slot in one component and a protrusion in the other. This segmentation allows each component to be manufactured independently using standard molding techniques, reducing overall manufacturing complexity while achieving the benefits of increased contact area and improved stability through their cooperative assembly.

AI summary
A penetrating lamp and a vehicle, the lamp comprising a housing (5) and an outer surface cover (6). The housing (5) is provided with a slot (51) extending along the extension direction Y of the housing (5). The outer surface cover (6) is provided with a protrusion (64) extending in the extension direction of the outer surface cover (6). The protrusion (64) is clamped to the slot (51), so that the housing (5) and the outer surface cover (6) form a light chamber. The vehicle comprises a penetrating lamp. By means of the cooperation between the linked protrusion (64) and the linked slot (51), the contact area between the housing (5) and the outer surface cover (6) is increased, and the stability of connection is improved.
