Solution Overview
Problem
Current bodily implants with fluid systems and inflatable members face challenges in reliable coupling and filtration, which can lead to inefficiencies and potential debris entry, affecting their performance and longevity.
Innovation Solution
The design incorporates a coupling member with various configurations, including spring biased clips and overlapping wires, to securely connect tubular members to pump assemblies, and integrates filters within the coupling members to prevent debris from entering the fluid system, ensuring reliable fluid transfer and implant functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coupling member is used to connect tubular members to pump assemblies, then the reliability of fluid transfer is improved, but the device complexity increases
Solution Approach 1:
The coupling member is disposed within the lumen of the tubular member, creating a nested configuration where the coupling member is inserted through and secured within the tubular member's lumen. This nesting approach provides reliable connection while maintaining a compact structure without requiring additional external components.
Solution Approach 2:
The coupling member acts as an intermediary component between the tubular member and the pump assembly, facilitating secure connection and proper fluid transfer. This intermediate element ensures reliable coupling while isolating the complexity to a single replaceable component rather than the entire system.
2Object-affected harmful factors
If filters are integrated within coupling members, then debris entry is prevented, but the manufacturing complexity increases
Solution Approach 1:
The filter is integrated within the coupling member, merging two functions (coupling and filtration) into a single component. This combination prevents debris entry while eliminating the need for separate filter assemblies, ultimately simplifying the overall manufacturing process despite the increased complexity of the coupling member itself.
Solution Approach 2:
The filter is disposed within the lumen of the coupling member, creating a nested structure where the filter is contained inside the coupling member. This nested configuration allows the filter to be manufactured as part of the coupling member or pre-installed within it, providing debris protection while maintaining a compact integrated design.
3Strength
If spring biased clips or overlapping wire members are used for coupling, then the secure connection is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The spring-biased clip utilizes elastic deformation and spring force to create a secure, self-adjusting connection. The dynamic nature of the spring allows it to compensate for minor variations in manufacturing tolerances while maintaining strong connection force, reducing the stringency of precision requirements.
Solution Approach 2:
The spring-biased clip and overlapping wire member with screw mechanism are designed to self-adjust and self-secure during assembly. The spring force automatically applies appropriate clamping pressure, and the screw mechanism allows for self-adjustment of tension, reducing the need for highly precise pre-manufacturing of connection interfaces.
