Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If traditional pressure vessels are used with frequent air replenishment to maintain pressure, then the required pressure for operation is maintained, but energy consumption increases significantly
Solution Approach 1:
Multiple cavities are merged into a single pressure vessel system, allowing pressure to be shared and maintained across all cavities collectively. When one cavity completes its operation, its pressure is transferred to other cavities that still require pressure, eliminating the need for frequent external air replenishment and significantly reducing energy consumption while maintaining reliable pressure levels.
Solution Approach 2:
The system maintains continuous pressure utilization by transferring pressure from cavities that have completed their cycles to cavities that are still operating. This continuous internal pressure redistribution ensures that pressure is always available when needed without requiring repeated energy-intensive replenishment cycles, achieving both energy efficiency and pressure reliability.
2Productivity
If large amounts of air are replenished frequently to maintain pressure, then the required pressure is maintained, but operational efficiency decreases
Solution Approach 1:
The pressure vessel system serves itself by automatically transferring pressure from cavities that have completed their operations to cavities that still require pressure. This self-service pressure redistribution mechanism eliminates the need for external intervention and frequent air replenishment, thereby improving operational efficiency while minimizing energy consumption.
Solution Approach 2:
Instead of discarding the pressure in cavities after operation completion, the system recovers and redistributes this pressure to other cavities that still require it. This recovery and reuse of pressure energy improves operational efficiency by reducing the frequency and volume of air replenishment needed, thereby lowering energy consumption.
3Loss of energy
If traditional pressure vessel structure is used, then simple design is maintained, but air must be replenished frequently leading to energy waste
Solution Approach 1:
Multiple cavities are combined within a single pressure vessel structure, sharing a common pressure environment. This merging approach requires only one pressurization system for the entire vessel, reducing energy waste from frequent replenishment while adding manageable complexity through the multi-cavity configuration that enables pressure transfer and reuse.
Solution Approach 2:
The pressure vessel structure serves multiple functions: it houses multiple cavities for simultaneous operations, enables internal pressure transfer between cavities, and eliminates the need for frequent external pressurization. This multi-functionality reduces energy waste while the added structural complexity is justified by the significant energy savings and operational improvements.

The solution effectively reduces energy consumption while maintaining the required pressure, improving operational efficiency and convenience in battery manufacturing by cyclically utilizing air and enhancing material handling processes.
Implementation Method 1
the control valve is connected between the at least two cavities; and when a standing operation under pressure has been completed in one of the cavities, the two cavities are controlled to maintain internal communication via the control valve, such that an internal pressure in the cavity in which the standing operation under pressure has been completed can be released to the other cavity
Implementation Method 2
the pressurization valve is configured to communicate with an air source. In this way, with use of the pressurization valve, a pressurization operation for the cavity can be effectively controlled
Implementation Method 3
the pressure relief valve is configured to communicate with the outside. In this way, with use of the pressure relief valve, the residual air pressure in the cavity can be released outside
