Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple elevated bag system is used for irrigation, then the system structure is simple, but the bag must be positioned above the person to create pressure difference
Solution Approach 1:
The pump is pre-assembled and integrated into the irrigation system before use, eliminating the need for complex assembly operations at the time of use. The system is prepared in advance with all components connected, allowing the user to simply fill the reservoir and operate the pump without needing to assemble multiple parts or position components correctly.
Solution Approach 2:
The pump function is extracted from the reservoir and integrated as a separate operable component, allowing the irrigation system to generate pressure without requiring elevated positioning. This separates the pressure-generating function from the gravitational field requirement, enabling the bag to remain at any convenient height.
2Ease of operation
If a manual pump system with multiple components is used, then the pressure can be controlled manually, but the system becomes complex and requires many operations
Solution Approach 1:
The pump is permanently connected to the reservoir, merging two previously separate components into a single integrated unit. This eliminates the need for separate assembly of the pump and reservoir, reduces the number of connection points that could fail, and simplifies the overall system while maintaining manual pressure control capability.
Solution Approach 2:
The pump-reservoir connection is pre-established during manufacturing, so that at the time of use, the user receives a ready-to-assemble unit requiring only the attachment of the insertion member. This preliminary preparation eliminates complex assembly steps and reduces the operational burden on the user.
3Adaptability or versatility
If the system requires assembly by the user, then the system can be customized, but it increases the time spent and risk of assembly errors
Solution Approach 1:
The critical connections between the reservoir and pump are pre-assembled and permanently fixed during manufacturing. This preliminary action ensures that the core system is ready for immediate use, eliminating the need for users to perform complex assembly operations and reducing the risk of assembly errors while maintaining the ability to attach different insertion members as needed.
4Adaptability or versatility
If connectors are used to join components, then the system is flexible, but the connectors may be accidentally disconnected during use
Solution Approach 1:
The reservoir and pump are permanently connected through integrated attachment mechanisms rather than using separate removable connectors. This merging of components eliminates the connection interface that could accidentally disconnect, ensuring reliable fluid-tight sealing while maintaining the flexibility to attach and detach the insertion member as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system simplifies the irrigation process, reduces assembly errors, minimizes user dependency, and enhances independence by providing a ready-to-use, easy-to-operate solution that is compact and discreet, while preventing contamination and ensuring efficient liquid flow.
Implementation Method 1
a pump for pumping liquid contained in the reservoir out through an outlet of the insertion member and into the body cavity
Implementation Method 2
The system may further comprise a non-return valve arranged to prevent liquid from flowing upstream from the pump towards the reservoir
