Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing controller boards are used without sequencing capability, then the device structure is simple, but energy efficiency is poor and optimal output cannot be achieved
Solution Approach 1:
The controller board segments the power delivery into multiple independently controllable channels, each capable of being activated in a specific sequence. This allows different stainless steel plates to receive power at different times according to a programmed sequence, optimizing energy efficiency without requiring complete system redesign
Solution Approach 2:
The controller board includes a memory device that stores pre-programmed sequences of channel activations. These sequences are prepared in advance and can be automatically executed, allowing the system to optimize energy efficiency through pre-planned sequencing without requiring complex real-time decision-making circuitry
2Productivity
If sequencing of positive and negative DC voltage is implemented, then energy efficiency improves, but the controller board requires programming capability and additional components
Solution Approach 1:
The controller board is designed as a universal platform that can control multiple channels of positive and negative DC voltage outputs simultaneously. The same basic architecture with processing circuit, memory device, and MOSFET-based drive outputs can handle different sequencing patterns and applications, reducing overall system complexity through standardization
Solution Approach 2:
The processing circuit acts as an intermediary between the memory device storing sequences and the physical output channels. It translates stored sequence data into actual channel activation signals, coordinating the complex sequencing operation without requiring direct complex wiring between all components
3Loss of energy
If multiple channels are activated simultaneously, then power delivery is simple, but energy efficiency deteriorates due to lack of sequencing
Solution Approach 1:
The controller board dynamically activates and deactivates output channels based on the programmed sequence, rather than maintaining static simultaneous activation. The processing circuit continuously monitors and adjusts channel states according to the sequence stored in memory, enabling energy-efficient operation while maintaining ease of operation through automatic control
