Self-Aligning Mounting Component for Surgical Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for surgical procedural elements, such as reamers, face challenges in aligning components efficiently before transferring high torque and axial loading, particularly in orthopaedic surgery.
Innovation Solution
A self-aligning mounting component with a mount body featuring distinct surface profile sections and alignment elements, allowing for passive rotary alignment when connecting surgical procedural elements to force applicators or extension elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting systems are used to connect surgical procedural elements, then the connection can be established, but manual alignment effort and time are increased
Solution Approach 1:
The mounting system incorporates self-aligning features where the components automatically orient themselves during connection. The second surface profile section with alignment elements passively guides rotational alignment when the components are brought together, eliminating the need for manual alignment operations and reducing alignment time without requiring active control mechanisms
Solution Approach 2:
The alignment elements are pre-configured on the mount body surfaces before connection occurs. The second surface profile section is manufactured with specific geometric features that anticipate the alignment requirement, allowing the components to self-align during the connection process rather than requiring alignment adjustments after connection
2Manufacturing precision
If alignment elements are added to the mount body, then self-alignment capability is improved, but the mount body thickness increases
Solution Approach 1:
The alignment elements are localized to specific regions of the mount body surface rather than uniformly distributed throughout. The second surface profile section contains the alignment features in a concentrated area, providing precise alignment functionality while minimizing the overall thickness increase of the mount body structure
Solution Approach 2:
The alignment elements create an asymmetric second surface profile section that differs from the first surface profile section. This asymmetric geometry provides unique alignment characteristics that enable precise self-alignment while using minimal material thickness, as the alignment function is achieved through geometric configuration rather than adding substantial material
