Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple vacuum sources are used, then the vacuum reliability is improved, but the system cost and complexity increase
Solution Approach 1:
The patent connects multiple vacuum sources to a common container, merging their output into a single enclosed volume. This allows a single pressure sensor to monitor all sources simultaneously, reducing the number of sensors needed while maintaining the ability to detect leaks from any individual source, thus resolving the contradiction between reliability and complexity.
Solution Approach 2:
The common container serves multiple functions: it encloses the volume for pressure measurement, connects multiple vacuum sources, and provides a centralized monitoring point. This multi-functional design reduces overall system complexity while maintaining vacuum reliability across all sources.
2Measurement precision
If a pressure sensor is added for each vacuum source, then the leak detection precision is improved, but the system cost increases
Solution Approach 1:
Multiple vacuum sources are merged into a common container, allowing a single pressure sensor to monitor the combined volume. The sensor can detect pressure changes indicating leaks from any source, achieving adequate measurement precision without requiring one sensor per vacuum source, thus reducing system cost and complexity.
3Productivity
If multiple vacuum sources are used, then the productivity is improved, but the system cost increases
Solution Approach 1:
Multiple vacuum sources are combined and connected to a common container with a single pressure sensor. This configuration enables monitoring of multiple suction cups simultaneously, improving productivity by allowing parallel operation while controlling system cost through reduced sensor requirements.
