Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioner stops operation when a temperature sensor fails, then the system reliability is maintained, but the productivity and user convenience deteriorate
Solution Approach 1:
The patent applies the copying principle by using sensor parameters from other indoor units as substitutes when the current unit's sensor fails. The control device obtains sensor parameters from peer indoor units operating in the same mode, creating a functional copy of the missing data to maintain continuous operation without compromising system reliability
Solution Approach 2:
The system implements beforehand cushioning by establishing a backup mechanism where sensor parameters from other indoor units are ready to be used when a sensor failure occurs. This preparatory arrangement ensures that the system can transition to using alternative data sources without interruption, maintaining both reliability and productivity
2Measurement precision
If the air conditioner stops operation when a temperature sensor fails, then the measurement precision is maintained, but the duration of action deteriorates
Solution Approach 1:
When the temperature sensor fails, the system copies sensor parameters from other indoor units operating in the same mode. This allows the control device to obtain replacement temperature data, maintaining measurement precision while extending the duration of action by enabling continued operation instead of shutdown
Solution Approach 2:
The system prepares alternative data sources in advance by having access to sensor parameters from other indoor units. This cushioning mechanism ensures that when a sensor failure occurs, the system can immediately switch to using alternative measurements, preserving both measurement precision and operational continuity
3Device complexity
If the air conditioner stops operation when a temperature sensor fails, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system uses copying to obtain sensor parameters from other indoor units, allowing the failed unit to continue operation with substituted data. This maintains ease of operation by avoiding shutdown and requiring no user intervention, while the automated nature of the copying process prevents significant increase in device complexity
Solution Approach 2:
The control device performs self-service by automatically detecting sensor failures and obtaining replacement parameters from other indoor units without requiring user intervention or complex external diagnostic systems. This maintains ease of operation while managing device complexity through automated self-correction
