Reversible Implant Fastening via Segmented Protrusion and Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implant devices face challenges in securely and reversibly maintaining their position within the body without causing movement, especially when subjected to various bodily movements or adjustments.
Innovation Solution
A fastening device with a protruding part featuring a through channel for an implant device feed member, allowing for the secure locking and adjustment of the implant device by feeding hydraulic or pneumatic fluid, electrical energy, or electrical signals, with the inlet and outlet accessible externally, enabling reversible locking and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a band type fastening device with a protruding part is used to lock the implant in place, then the implant is securely fastened and does not move freely, but the fastening device becomes complex and difficult to reverse
Solution Approach 1:
The fastening device is divided into two separate sections: a first fastening section with a through hole and a second fastening section with a protruding part. This segmentation allows the device to be assembled and disassembled by separating the sections, simplifying the reversal process while maintaining secure fastening when assembled.
Solution Approach 2:
The fastening device transitions from a static locked state to a dynamic reversible state. The protruding part can be inserted through the through hole to lock the sections together, and later removed to detach the sections, enabling controlled dynamic behavior for both securing and reversing the fastening.
2Reliability
If the protruding part is made of flexible material with a ball shaped end to prevent separation, then the band ends remain locked during movement, but the device cannot be easily reversed or detached
Solution Approach 1:
By separating the fastening device into two detachable sections with a through hole and protruding part, the design enables both stable locking during operation and easy reversal when needed. The sections can be assembled for secure fastening and disassembled for removal, providing operational flexibility.
Solution Approach 2:
The through hole acts as an intermediary element that facilitates both the locking function (by receiving the protruding part) and the reversal function (by allowing removal of the protruding part). This intermediary structure enables the same component to serve dual purposes: maintaining stability during use and enabling easy detachment when required.
3Ease of operation
If the fastening device is designed to be reversible in two steps, then the implant can be securely fastened and later detached, but the device complexity increases with additional components
Solution Approach 1:
The fastening device is segmented into two main sections that can be assembled and disassembled. This segmentation provides a clear two-step reversal process: first removing the protruding part from the through hole, then separating the two sections. While this adds structural elements, the segmentation itself is a fundamental design principle that simplifies the overall system compared to more complex reversible mechanisms.
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 solution provides a fully reversible and secure method to keep the implant in place, minimizing movement and allowing for adjustable positioning, thereby enhancing the stability and usability of the implant device.
Implementation Method 1
the ball shaped end is elastically deformed when pushed through the hole and regains its shape when leaving the hole, thus keeping the band ends locked to each other
