Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple sets of PID algorithms are used to control the power of each heating wire separately, then the temperature control precision is improved, but the device complexity and system resource consumption increase
Solution Approach 1:
The patent merges multiple independent PID control algorithms into a single centralized control system. The controller integrates temperature detection from multiple sensors and coordinates power distribution to multiple heating wires through one unified algorithm, reducing computational redundancy and simplifying the control structure while maintaining precise temperature control across different zones.
Solution Approach 2:
The single control algorithm is designed to perform multiple functions: it detects temperatures from multiple sensors, calculates power requirements for different heating zones, adjusts power distribution dynamically, and prevents condensation by coordinating heating across all surfaces. This universal controller replaces multiple specialized control algorithms.
2Manufacturing precision
If multiple sets of PID algorithms are used to control heating wires, then the temperature control precision is improved, but the system resource consumption increases
Solution Approach 1:
By merging multiple PID algorithms into one centralized control system, the patent eliminates redundant computational operations. The single controller shares processing resources, memory, and calculation frameworks across all heating zones, significantly reducing CPU usage, memory consumption, and overall system resource requirements while maintaining precise temperature control.
3Device complexity
If thyristors are used to control the power of multiple heating wires on one path, then the device complexity is reduced, but the ability to separately control each heating wire is lost leading to condensation
Solution Approach 1:
The patent segments the control of each heating wire into independent controllable units while maintaining a unified control architecture. Each heating wire receives individual power control signals from the centralized controller, allowing separate adjustment of each heating element's power consumption. This enables precise local temperature management on different surfaces, preventing condensation by ensuring each zone maintains appropriate temperature independently.
