Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heating methods are used for electrode group structures, then heating can be performed, but temperature variations between multiple electrode group structures occur and heating time is prolonged
Solution Approach 1:
A heat conduction plate is introduced as an intermediary between the heating source and the electrode group structures. The plate comes into contact with the current collectors of multiple electrode group structures, enabling uniform heat conduction to all structures simultaneously, thereby reducing temperature variations and heating time
Solution Approach 2:
The patent replaces conventional thermal radiation or convection heating methods with direct thermal conduction through the heat conduction plate. This substitution of heating mechanism enables more efficient and uniform heat transfer to the electrode group structures
2Productivity
If heating temperature is increased to shorten heating time, then heating efficiency improves, but temperature control stability deteriorates
Solution Approach 1:
A controller is implemented that receives temperature information from temperature sensors and adjusts the heating power accordingly. This feedback control mechanism maintains stable temperature control while achieving efficient heating by dynamically adjusting heating parameters based on actual temperature conditions
Solution Approach 2:
The system dynamically adjusts heating parameters (temperature, power) based on real-time temperature measurements. By changing operating parameters adaptively, the system achieves both high heating efficiency and stable temperature control
