Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional medical suction devices are used, then liquid removal function is reliable, but device size becomes large and complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated device. The compressible object serves as both the vacuum source (through its ability to create negative pressure when compressed) and the collection reservoir. The catheter is integrated within the compressible object, eliminating the need for separate connections. This merging of functions reduces device complexity while maintaining reliable liquid removal capability.
Solution Approach 2:
The compressible object performs multiple functions: it acts as a vacuum source when compressed, serves as a collection reservoir when expanded, and provides structural support for the catheter. This multi-functionality eliminates the need for separate vacuum pumps, collection containers, and structural frameworks, thereby reducing overall device complexity while ensuring reliable operation.
2Power
If conventional medical suction devices are used, then suction capability is sufficient, but portability is limited
Solution Approach 1:
The device is self-contained and self-operating. The compressible object generates its own vacuum capability through manual compression by the user, eliminating the need for external power sources or heavy vacuum pumps. The same compressible structure serves as both the power generation mechanism and the collection reservoir, reducing overall device weight and improving portability while maintaining sufficient suction capability for medical applications.
3Device complexity
If conventional medical suction devices are used, then multiple components are provided, but ease of operation is reduced
Solution Approach 1:
The patent merges the catheter placement and liquid collection functions into a single integrated structure. The catheter is positioned within the compressible object, and liquid is collected directly in the same compressible reservoir. This eliminates the need for separate collection containers and complex connection mechanisms, making the device easier to operate with fewer components.
Solution Approach 2:
The device can be segmented into two main parts: the compressible object (which serves as both vacuum source and reservoir) and the catheter. This simple segmentation allows for easy assembly and operation, where the user simply compresses the object to create vacuum and collect liquid, without needing to manage multiple separate components.
