Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate capillary tubes are used to connect multiple evaporators to the refrigeration circuit, then each evaporator can be individually controlled, but the device complexity and construction space increase significantly
Solution Approach 1:
The patent combines multiple separate capillary tubes and suction pipes into a single integrated multi-suction line assembly. This merging reduces the number of separate components and connections required, thereby reducing device complexity and construction space while maintaining the ability to individually control each evaporator through separate capillary tube connections.
2Adaptability or versatility
If multiple separate capillary tubes are used to connect multiple evaporators, then individual evaporator control is achieved, but the construction space within the refrigeration device is reduced
Solution Approach 1:
The patent merges multiple capillary tubes and suction pipes into a single multi-suction line assembly, consolidating what would otherwise be separate spatial requirements into one integrated component. This significantly reduces the construction space needed within the refrigeration device while preserving individual evaporator control capabilities.
Solution Approach 2:
The multi-suction line assembly serves multiple functions simultaneously: it acts as both the capillary tube connection and the suction pipe for multiple evaporators. This multi-functionality reduces the overall space requirement compared to having separate dedicated lines for each function.
3Adaptability or versatility
If multiple separate capillary tubes are used to connect multiple evaporators, then individual evaporator control is achieved, but the cost increases
Solution Approach 1:
The patent combines multiple capillary tubes and suction pipes into a single manufactured assembly, which reduces the number of separate manufacturing steps, connections, and assembly operations required. This consolidation lowers manufacturing costs while maintaining the ability to individually control each evaporator through the integrated design.
4Volume of stationary object
If a single suction pipe is used to connect multiple evaporators to the compressor, then the construction space is reduced, but the refrigerant flow control complexity increases
Solution Approach 1:
The patent combines multiple capillary tubes with the suction pipe into an integrated multi-suction line assembly where the capillary tubes are positioned along the suction pipe. This merging allows space reduction while maintaining simplified refrigerant flow control, as the separate capillary tube connections enable individual evaporator control without requiring complex flow management in the suction line.
