Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED modules are divided into multiple segments with switch control, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The LED lighting apparatus is divided into multiple independently controllable segments, where each segment can be selectively switched on or off. This segmentation allows flexible configuration of lighting patterns and optical parameters without requiring complete system redesign, resolving the contradiction by enabling adaptability through modular division while keeping each module relatively simple.
Solution Approach 2:
The patent implements dynamic control of LED segments through switch circuits that can adjust which segments are active based on lighting requirements. This dynamic reconfiguration capability allows the system to adapt to different applications while maintaining manageable complexity through standardized switching mechanisms.
2Ease of operation
If multiple switches and switch control units are added for adjusting optical parameters, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The switch control system is designed to be user-operable without requiring external control devices or complex programming. Users can directly manipulate the switches to achieve desired lighting configurations, improving ease of operation while avoiding the complexity of automated control systems.
3Adaptability or versatility
If LED modules are segmented for selective connection, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the LED lighting apparatus into modular segments that can be manufactured using standardized processes and then assembled through simple connections. This segmentation enables economies of scale in manufacturing individual modules while providing configuration flexibility through their modular assembly, resolving the contradiction between adaptability and manufacturing cost.
