Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control of stage lamp holders by lighting engineers is used, then flexibility in operation is maintained, but human resource costs increase and stage errors readily occur
Solution Approach 1:
The light tracking device autonomously performs tracking, positioning, and control functions without requiring manual intervention by lighting engineers. The system uses sensors to detect target positions and automatically adjusts lamp holder angles and positions, eliminating the need for human operators while maintaining high tracking accuracy and reliability.
Solution Approach 2:
The patent replaces manual mechanical control with an automated system combining sensors, processors, and motorized actuators. The system uses electronic signal processing and automated motor control to substitute human-operated mechanical adjustments, thereby improving reliability while reducing operational complexity.
2Productivity
If pre-set light tracking procedure by stage light console is used, then human resource costs are reduced, but stage errors readily occur and adaptability to different scenarios is limited
Solution Approach 1:
The system dynamically adjusts light tracking parameters in real-time based on sensor feedback and target position changes. Unlike fixed pre-set procedures, the automated system continuously adapts its control signals to lamp holder angles and positions, enabling flexible response to varying performance requirements while maintaining high operational efficiency.
Solution Approach 2:
The patent incorporates sensor feedback mechanisms that continuously monitor target positions and lamp holder states. This closed-loop feedback system enables real-time adjustments to tracking parameters, allowing the system to adapt to different scenarios and correct errors automatically, thereby enhancing both versatility and productivity.
3Extent of automation
If conventional stage lighting systems are modified for computer control, then human resource costs are saved, but proper modification is still needed for stages and device complexity increases
Solution Approach 1:
The patent designs a universal light tracking device that can be applied to various stage configurations and performance types without requiring extensive custom modifications. The system integrates multiple functions (tracking, positioning, dimming, focus control) into a single automated platform, reducing overall system complexity while achieving high automation levels.
Solution Approach 2:
The system divides the light tracking function into modular components: sensor modules for detection, processor modules for signal processing, and actuator modules for physical adjustment. This segmentation allows for easier integration and reduces complexity by enabling standardized interfaces and independent optimization of each functional module.
4Adaptability or versatility
If smart light tracking device is developed for automatic control, then manual intervention is eliminated and adaptability to smart applications is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple control functions (light tracking, focus adjustment, dimming control, position management) into a single integrated automated system. By merging these functions into one coordinated platform rather than separate systems, the device achieves high adaptability to smart applications while managing overall complexity through functional integration.
