Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a plurality of LED light sources is arranged at various positions inside the curing chamber and the heating temperature is changed, then uniform curing can be achieved, but the configurations of the curing mechanism and circuit become complicated
Solution Approach 1:
The curing chamber is divided into multiple heating zones with independent temperature control. Each zone has its own heating element and temperature sensor, allowing separate control of temperature in different regions to achieve uniform curing across the entire chamber without requiring complex overall configuration
Solution Approach 2:
Different regions of the curing chamber are assigned different heating characteristics based on their specific curing requirements. The patent implements localized temperature adjustment by positioning heating elements and adjusting their power output according to the actual curing needs of different areas, achieving uniform curing through localized optimization rather than uniform complex configuration
2Manufacturing precision
If multiple LED light sources are placed at various positions to vary heating temperature, then curing uniformity improves, but the circuit configuration becomes complicated
Solution Approach 1:
Multiple independent temperature control circuits are merged into a unified control system. The patent integrates the control of multiple heating zones into a single controller that coordinates temperature adjustment across all zones, simplifying the overall circuit configuration while maintaining the ability to achieve uniform temperature distribution
Solution Approach 2:
The control circuit is designed with multi-functionality to handle various heating scenarios. A single control circuit can adjust and coordinate multiple heating zones, providing universal control capability that eliminates the need for separate complex circuits for each heating element, thereby simplifying the overall circuit configuration while maintaining temperature uniformity
