Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If replacement reservoirs are installed underneath the countertop for engagement with the dispensing system, then the dispensing system can provide liquid and air simultaneously, but the coupling of replacement reservoirs to the dispensing system becomes difficult and cumbersome
Solution Approach 1:
The pump assembly is divided into a stationary pump body and a replaceable cartridge that contains the piston-forming element and seals. This segmentation allows the cartridge to be easily removed and replaced without dealing with complex coupling mechanisms, resolving the contradiction between adaptability and ease of operation.
Solution Approach 2:
The piston-forming element and seals are extracted from the main pump body and placed in a separate replaceable cartridge. This extraction simplifies the replacement process by allowing users to simply swap cartridges rather than manually repositioning multiple components, thereby improving ease of operation while maintaining adaptability.
2Adaptability or versatility
If a piston pump assembly is used to simultaneously dispense liquid and air, then dispensing functionality is improved, but the complexity of the dispensing system increases
Solution Approach 1:
The liquid pump and air pump functions are merged into a single piston pump assembly where one piston-forming element simultaneously performs both liquid pumping and air pumping actions. This merging maintains adaptability for simultaneous dispensing while reducing overall system complexity compared to using two separate pump mechanisms.
Solution Approach 2:
The piston-forming element is designed with multi-functionality to serve both as a liquid pump component and an air pump component. This universal design allows a single component to perform multiple functions, thereby maintaining dispensing versatility while minimizing the number of parts and reducing system complexity.
3Device complexity
If the discharge outlet is fixed relative to the piston chamber-forming body, then the pump structure is simplified, but the ability to adapt to different mounting configurations is reduced
Solution Approach 1:
While the discharge outlet is fixed relative to the piston chamber-forming body for structural simplicity, the entire pump assembly is designed to be dynamically positionable within the dispensing system. The cartridge can be oriented and mounted in different configurations, providing adaptability without requiring a complex adjustable discharge outlet mechanism.
