Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED modules are randomly mixed and arranged with different address codings, then controllable random flashing function is achieved, but device complexity increases
Solution Approach 1:
The system segments LED modules into different address coding groups (first coding, second coding, third coding) that can be randomly distributed. Each segment responds to specific address signals, enabling random flashing patterns without requiring complex centralized control logic.
Solution Approach 2:
The power line edge signal generator is designed to generate multiple types of address signals (first, second, and third address signals) that can control different address coding groups. This multi-functional signal generator handles both synchronous color effects and random flashing functions through a single device.
2Productivity
If multiple LED driver address codings are used for random arrangement, then production efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
Each LED module is assigned a specific address coding (first, second, or third coding) that defines its local control characteristics. This allows modules to be manufactured with fixed address codings and then randomly arranged in the final product, improving production efficiency while maintaining control precision through the address signal matching mechanism.
3Stability of the object's composition
If all LED modules respond to the same control signal, then synchronous color effect is achieved, but adaptability for random flashing is reduced
Solution Approach 1:
The system dynamically switches between different control modes by generating different types of address signals. When first address signals are generated, all modules respond synchronously for color effects. When second or third address signals are generated, specific address coding groups respond for random flashing, enabling dynamic adaptation between different lighting modes.
