A standardized light source module with a frame having a stepwise structure and detachable light emitting portions connected via elastic connections to an electrode pattern, allowing for universal installation and easy maintenance by replacing faulty units without discarding the entire module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual mold patterns are designed and manufactured for each vehicle model, then the light source module can be precisely fitted to specific lamp designs, but the manufacturing cost increases and maintenance becomes more difficult
Solution Approach 1:
The light source module is divided into a standardized frame structure and detachable light emitting portions. The frame serves as a universal base that can accommodate different light emitting portions, while each portion can be independently replaced. This segmentation allows the same frame to be used across multiple vehicle models without requiring custom molds for each model, thereby reducing manufacturing costs while maintaining adaptability to specific lamp designs through selective light emitting portion installation.
Solution Approach 2:
The frame structure is designed as a universal component that can serve multiple vehicle models. The standardized base portion with integrated electrode patterns and connection structures enables the same frame to support different light emitting portions configured for various lamp designs. This universality eliminates the need to manufacture separate molds for each vehicle model, directly reducing manufacturing costs while preserving the ability to fit specific lamp design requirements through interchangeable light emitting portions.
2Adaptability or versatility
If individual mold patterns are designed for each vehicle model, then the light source module fits the lamp design, but maintenance becomes more complex requiring specific molds for each model
Solution Approach 1:
By segmenting the light source module into a permanent standardized frame and replaceable light emitting portions, the patent enables easy maintenance. When a light emitting portion fails, only that specific portion needs to be replaced rather than the entire module. The standardized connection structures (protrusions and recesses) ensure that any light emitting portion can be easily attached to or removed from the frame without requiring specialized molds or tools, significantly simplifying maintenance procedures while maintaining the ability to fit various lamp designs.
3Ease of manufacture
If a standardized light emitting unit structure is implemented, then maintenance is facilitated and manufacturing costs reduce, but the complexity of connections increases
Solution Approach 1:
The patent merges multiple functions into the connection structure between the light emitting portion and frame. The elastic connections simultaneously provide mechanical attachment (through protrusions and recesses), electrical connection (through electrode patterns), and structural support. By combining these functions into a single integrated connection mechanism rather than separate components, the patent reduces overall device complexity while achieving standardized manufacturing. The elastic material properties enable the connection to be both simple in design and robust in function, eliminating the need for multiple separate fastening and electrical connection components.

Function Achieved in This Case
The standardized module reduces manufacturing costs and facilitates maintenance by allowing interchangeable light emitting portions, eliminating the need for multiple molds and enabling efficient assembly across various vehicle models.
Implementation Method 1
The bent portion may be configured to elastically deform in response to external force that is applied to the bent portion, to generate repellent force

AI summary
A light source module includes a frame comprising base portions disposed on different levels, respectively, and an electrode pattern disposed on the base portions. The light source module further includes light emitting portions detachably disposed on the respective base portions, and connections having elasticity, disposed between the respective light emitting portions and the frame, and configured to supply power to the light emitting portions through the electrode pattern.
