Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a control system uses a central processing unit with multiple sensors to detect individual component conditions, then measurement precision is improved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines multiple sensor functions into a single sensor that detects overall cooling system performance parameters. Instead of using separate sensors for each component (compressor, condenser, evaporator, etc.), the invention uses one sensor to monitor the cooling output, thereby simplifying the control architecture while maintaining adequate measurement capability for system-wide optimization.
Solution Approach 2:
The single sensor in the invention serves multiple functions by detecting cooling system performance that reflects the combined state of all components. This universal measurement approach allows the control system to optimize all components simultaneously based on overall system performance rather than individual component readings.
2Reliability
If a control system uses multiple sensors to monitor each cooling system component, then reliability of component monitoring is improved, but manufacturing cost increases
Solution Approach 1:
The invention merges multiple monitoring functions into a single sensor placement, reducing the number of assembly steps and connections required. Instead of installing and wiring multiple sensors throughout the system, the single sensor approach simplifies manufacturing assembly while maintaining reliable monitoring of cooling system performance.
3Ease of operation
If control is performed on a local and individual basis for each component, then ease of control implementation is improved, but energy consumption increases
Solution Approach 1:
The invention merges individual component control into integrated system-wide control. By using a single sensor to detect overall cooling performance and controlling all components based on this unified feedback, the system optimizes energy consumption across all components simultaneously rather than having each component operate independently, thereby reducing total energy usage.
4Stability of the object's composition
If the cooling system operates continuously to maintain temperature, then temperature stability is improved, but energy consumption increases
Solution Approach 1:
The invention implements feedback control based on actual cooling system performance detected by the sensor. The control system continuously monitors the cooling output and adjusts component operation accordingly, allowing the system to maintain temperature stability while consuming less energy by operating components only when and as much as needed rather than continuous operation.
