Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing methods are used for distribution pipes, then manufacturing flexibility is maintained, but manufacturing precision deteriorates due to varying temperatures requiring repeated processing
Solution Approach 1:
The patent applies preliminary action by pre-cooling the flow tube to a temperature below ambient temperature before machining the liquid dispensing holes. This temperature control is performed in advance of the machining operation, ensuring that the flow tube maintains dimensional stability during the precision machining process, thereby eliminating the need for repeated processing while maintaining high manufacturing efficiency
2Ease of manufacture
If traditional vacuum brazing furnaces are used for welding adapters, then welding capability is achieved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive vacuum brazing furnaces with a simpler, less costly heating device that performs the same welding function. The heating device heats the flow tube to a temperature suitable for adapter welding, achieving the required welding capability without the high cost of vacuum brazing equipment, thereby significantly reducing manufacturing costs
