Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual assembly and disassembly of atomizing sheets is used to adjust lighting effects, then lighting effect adjustment is possible, but it is time-consuming and laborious
Solution Approach 1:
The patent replaces the mechanical system of manual atomizing sheet assembly/disassembly with an electronic control system. The control circuit receives control signals and adjusts the lighting effects electronically, eliminating the need for physical manipulation of atomizing sheets and enabling instant adjustment without time loss.
Solution Approach 2:
The patent introduces dynamic control capabilities through the control circuit that can adjust lighting parameters in real-time based on control signals. This allows the lighting effects to be dynamically changed without the static, time-consuming process of manual atomizing sheet changes.
2Adaptability or versatility
If atomizing sheets are added to change lighting effects, then lighting effect can be adjusted, but heat energy cannot be effectively discharged
Solution Approach 1:
The patent replaces the use of physical atomizing sheets with an electronic control system that adjusts lighting effects through electrical signals. This eliminates the heat-blocking effect of atomizing sheets while maintaining lighting effect variability, allowing proper heat dissipation from the light source.
Solution Approach 2:
The patent changes the method of controlling lighting effects from physical modification (atomizing sheets) to electrical parameter adjustment (control signals). This allows lighting effects to be varied while maintaining thermal performance, as the electronic control system does not impede heat dissipation.
3Illumination intensity
If conventional control methods are used to adjust brightness, then light softness is improved, but application scenarios are limited
Solution Approach 1:
The patent creates a universal control system that can handle multiple lighting control functions through a single interface. The control circuit responds to various control signals to adjust different lighting parameters (brightness, color temperature, timing), enabling the stage light to adapt to diverse application scenarios while maintaining light softness control.
Solution Approach 2:
The patent introduces dynamic, programmable control capabilities that allow the lighting system to adapt to different application scenarios. The control circuit can process various control signals to create different lighting effects and sequences, providing versatility across multiple application contexts while maintaining the ability to control light softness.
