Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering or connectors are used to connect LED modules, then reliable electrical connection is achieved, but manufacturing cost and processing complexity increase
Solution Approach 1:
The patent extracts the connection function from dedicated connectors and soldering processes, integrating it directly into the mounting surface through conductive lines. This eliminates the need for separate connector components and complex soldering operations, reducing both device complexity and manufacturing cost while maintaining reliable electrical connection.
Solution Approach 2:
The patent merges the mounting surface and electrical connection function into a single integrated structure. The conductive lines are directly formed on the mounting surface, combining the mechanical mounting function and electrical connection function into one unified system, thereby eliminating the need for separate connectors and reducing overall complexity.
2Reliability
If dedicated connectors are used for LED module connection, then stable electrical connection is achieved, but investment and processing costs increase
Solution Approach 1:
The patent replaces expensive dedicated connectors with simple, inexpensive conductive lines directly formed on the mounting surface. These conductive lines are integrated into the mounting structure itself, eliminating the need for costly separate connector components while maintaining adequate connection stability for the application.
Solution Approach 2:
The mounting surface is designed to serve multiple functions simultaneously: mechanical mounting of LED modules and electrical connection through integrated conductive lines. This multi-functional design eliminates the need for dedicated connectors, reducing investment and processing costs while maintaining connection stability.
3Productivity
If automated assembly process is implemented with traditional connectors, then production efficiency is improved, but processing costs and complexity increase
Solution Approach 1:
The patent removes the connector component from the automated assembly process, replacing it with conductive lines directly integrated into the mounting surface. This simplification enables more straightforward automated assembly operations, improving productivity while reducing the complexity of the connection system.
4Ease of manufacture
If fixed-width modules are used, then manufacturing is simplified, but installation flexibility is reduced
Solution Approach 1:
The patent introduces flexibility through the conductive lines on the mounting surface, which can be configured in various patterns and lengths to accommodate different module arrangements. This dynamic configuration capability allows the system to adapt to different installation requirements while maintaining simple module manufacturing processes.
