Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instrumentation mounts lack easy adjustability and mechanical enhancement for securely holding multiple devices, particularly in minimally invasive surgical procedures where smaller incisions are used, necessitating improved torque for secure mounting and positioning.
Innovation Solution
A torque enhancing apparatus with extendable moment arms and a pivotable ball mechanism between sockets, providing a mechanical advantage for adjusting and securing instrumentation, allowing for enhanced torque application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional mounting apparatuses are used, then the structure remains simple, but the torque application is insufficient for secure mounting
Solution Approach 1:
The mounting apparatus incorporates extendable moment arms that can dynamically adjust their length to provide variable mechanical advantage. The moment arms can be extended when high torque is needed for mounting operations, then retracted when not needed, allowing the system to adapt its mechanical properties rather than being fixed.
Solution Approach 2:
The invention adds a spatial dimension to the mounting apparatus by incorporating extendable moment arms that protrude outward from the socket assembly. This dimensional extension creates longer lever arms for torque application without increasing the base socket size, effectively solving the torque deficiency while maintaining structural compactness.
2Strength
If smaller access incisions are used in minimally invasive surgery, then patient trauma is minimized, but the capability to securely mount instrumentation is reduced
Solution Approach 1:
The moment arms are designed to be extendable only during mounting operations, providing enhanced torque capability when needed. During actual surgical procedures, the moment arms can be retracted, maintaining a compact profile that fits through small incisions. This dynamic adjustment allows the system to provide strong mounting capability without requiring permanently large access points.
Solution Approach 2:
The mounting apparatus is segmented into modular components including the socket assembly and detachable moment arms. This segmentation allows the moment arms to be extended for mounting operations and then collapsed or removed, enabling the system to fit through small surgical incisions while still providing robust mounting capability when deployed.
3Strength
If extendable moment arms are added to enhance torque, then mounting capability is improved, but device complexity increases
Solution Approach 1:
The moment arms incorporate a telescopic or extendable mechanism that allows them to be lengthened only when torque enhancement is needed. The extendable portion can be mechanically locked in place during high-torque operations, then retracted to a compact position during normal use, providing torque enhancement on-demand rather than as a permanent structural addition.
