Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single transformer is used to supply voltage to the heater, then the device structure is simple, but the heating efficiency and user experience cannot be optimized under different conditions
Solution Approach 1:
The patent divides the voltage supply system into multiple transformers, each capable of providing different voltage levels. This segmentation allows the system to select appropriate voltage levels based on heating conditions, thereby improving heating efficiency without requiring complete redesign of the entire system.
Solution Approach 2:
The patent implements dynamic voltage selection by controlling different transformers based on real-time temperature feedback and elapsed time. The system transitions from static single-voltage supply to dynamic multi-voltage supply, optimizing heating efficiency at different stages of the heating process.
2Speed
If high voltage is continuously applied to the heater, then heating speed is fast, but energy waste increases and user experience deteriorates due to overheating
Solution Approach 1:
The patent implements periodic voltage adjustment by switching between different transformers based on elapsed time intervals and temperature thresholds. High voltage is applied only during necessary periods, followed by lower voltage or idle states, preventing continuous energy waste while maintaining adequate heating speed.
Solution Approach 2:
The patent changes the voltage parameter dynamically based on heating conditions. By adjusting voltage levels according to temperature feedback and time elapsed, the system achieves fast heating when needed while reducing energy consumption during maintenance phases, resolving the contradiction between heating speed and energy efficiency.
3Reliability
If voltage is not adjusted based on elapsed time, then the control system is simple, but chain smoking cannot be detected and user experience is compromised
Solution Approach 1:
The patent implements feedback control by monitoring elapsed time since the last heating cycle and using this information to determine appropriate voltage levels. This feedback mechanism enables chain smoking detection (when elapsed time is too short) and adjusts voltage accordingly, improving reliability without requiring complex additional sensors.
Solution Approach 2:
The patent performs preliminary assessment of elapsed time before applying voltage to determine the appropriate transformer selection. This preliminary action prevents inappropriate high-voltage application in chain smoking scenarios, ensuring user safety and experience while maintaining relatively simple control logic.
4Ease of operation
If multiple transformers are controlled based on multiple parameters, then user experience is optimized, but the control complexity and computational load increase
Solution Approach 1:
The patent applies different control strategies to different transformers based on their specific voltage output characteristics. Each transformer is associated with specific heating conditions, allowing localized optimization without requiring complex global control algorithms. This local quality approach simplifies the overall control system while maintaining optimized user experience.
