Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional securing means for space access devices fail to securely engage internal spaces or openings for extended periods, do not self-adjust to the shape of the space, lack means for adjusting the applied force, and prevent fluid flow.
Innovation Solution
A securing mechanism with outwardly projecting members that self-conform to the internal space, adjust the applied force, and allow fluid flow, using materials like silicone and polyurethane, with pressure ranges optimized to ensure secure and comfortable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional securing means (securing rings, compliant outer surfaces) are used, then the device can be inserted in internal spaces, but the device does not securely engage for extended periods and is easily dislodged
Solution Approach 1:
The securing mechanism employs adjustable outwardly projecting members that can dynamically adapt their position and configuration. The members are movable relative to the device housing, allowing them to adjust to the contours of the internal space and maintain secure engagement over extended periods, resolving the contradiction between secure engagement and engagement duration.
Solution Approach 2:
The securing mechanism changes physical parameters by adjusting the extent to which outwardly projecting members engage with the internal space surface. This adjustability allows optimization of engagement force and contact area, enabling secure long-term engagement without excessive pressure, thus resolving the contradiction between secure engagement and duration.
2Ease of manufacture
If preset circular shape securing means are used, then the device can be manufactured easily, but it does not self-conform to the shape of the internal space or opening
Solution Approach 1:
The securing mechanism is segmented into multiple outwardly projecting members that can independently adjust their position. This segmentation allows each member to conform to different portions of the internal space surface, achieving self-conformation while maintaining ease of manufacture through modular design and standardized components.
Solution Approach 2:
The outwardly projecting members are designed to be movable and adaptable rather than fixed in a preset circular configuration. This dynamic capability enables the securing mechanism to self-conform to various internal space shapes while still being manufactured using standard processes, resolving the contradiction between ease of manufacture and adaptability.
3Device complexity
If conventional securing means are used, then the device structure is simple, but there is no means for fluid flow through the device or between the device and the internal space
Solution Approach 1:
The outwardly projecting members serve multiple functions: they provide securing engagement with the internal space surface and simultaneously create fluid flow pathways. By integrating these two functions into a single structural element, the mechanism achieves fluid flow capability without significantly increasing overall device complexity, resolving the contradiction between structural simplicity and functional versatility.
4Force
If conventional securing means are used, then the device applies a predetermined narrow range of force, but there is no means for adjusting the force applied to the surface
Solution Approach 1:
The securing mechanism employs outwardly projecting members that are movable and adjustable, allowing the applied force to be dynamically modified. This adjustability enables optimization of securing force for different internal space surfaces and user comfort requirements, resolving the contradiction between force application and force adjustability.
Solution Approach 2:
The mechanism enables change in the physical parameter of applied force through adjustable engagement of the outwardly projecting members. By modifying the extent and manner of contact with the internal space surface, the force can be adjusted within a broader range, resolving the contradiction between predetermined force and force adjustability.
