Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical implants for restricting luminary organs, such as the urethra, often cause damage due to their design, which necessitates a less damaging restriction method.
Innovation Solution
A support element with integrated fluid conduits is used to house and protect hydraulic constriction elements, reducing the risk of damage by minimizing protrusions and providing a surrounding structure for the luminary organ, along with an electrode arrangement for muscle stimulation to enhance implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional restriction devices are used to constrict the luminary organ, then the constriction function is achieved, but the organ is damaged due to protruding portions and lack of protection
Solution Approach 1:
The hydraulic constriction element is nested within the support element, which provides a protective surrounding structure. The fluid conduit is integrated into the support element, creating a nested configuration where the constriction mechanism is housed within the protective structure, eliminating exposed protruding portions that could damage the organ.
Solution Approach 2:
The support element forms a flexible surrounding structure that protects the hydraulic constriction element while conforming to the luminary organ. This shell-like structure provides protection without rigid contact, reducing the risk of organ damage while maintaining the constriction function.
2Volume of moving object
If the hydraulic constriction element is exposed without integration, then the constriction function is accessible, but the space occupied is larger and protection is reduced
Solution Approach 1:
The fluid conduit is merged with the support element, integrating the fluid delivery system into the protective structure. This combination eliminates the need for separate conduit pathways, reducing the overall space occupied while providing continuous protection for the fluid entry to the hydraulic constriction element.
Solution Approach 2:
The fluid conduit is nested within the support element, with the conduit integrated into the wall structure of the support element. This nesting arrangement protects the fluid entry while minimizing the external dimensions of the device.
3Device complexity
If multiple separate components are used for support and fluid delivery, then the functions are distinct, but the device complexity increases and space is wasted
Solution Approach 1:
The support element and fluid conduit are merged into a single integrated component. The conduit is formed as part of the support element structure, reducing the number of separate parts while maintaining distinct functions of support and fluid delivery.
Solution Approach 2:
The support element serves multiple functions: providing structural support, protecting the hydraulic constriction element, and serving as the fluid conduit pathway. This multi-functional design reduces device complexity while maintaining ease of manufacture through a unified structure.
