Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid adhesive delivery system is used, then structural stability is maintained, but the ability to apply adhesive at multiple angles is limited
Solution Approach 1:
The adhesive delivery system is divided into multiple segments: a handle portion, a shaft portion, and a tip portion. Each segment can pivot relative to the others through ball-and-socket joints, allowing independent movement while maintaining overall structural integrity. This segmentation enables multi-angle adhesive application without requiring a completely flexible structure.
Solution Approach 2:
The system incorporates dynamic elements including a flexible conduit that can bend and flex, and ball-and-socket joints that allow pivotal movement between segments. These dynamic components enable the rigid structure to adapt to different angles and positions during adhesive application, resolving the contradiction between structural stability and angular versatility.
2Adaptability or versatility
If a flexible adhesive delivery system is used, then multi-angle application is enabled, but precision and control are reduced
Solution Approach 1:
By segmenting the delivery system into controlled portions (handle, shaft, tip) connected through defined pivot joints, the patent maintains precision control over each segment's movement while allowing overall flexibility. The ball-and-socket joints provide controlled degrees of freedom, ensuring precise adhesive placement despite system flexibility.
Solution Approach 2:
The flexible conduit acts as an intermediary element between the handle and tip portions, transmitting adhesive while accommodating angular movements. This intermediary component allows the system to maintain both flexibility for multi-angle application and precision through its controlled flexibility characteristics.
3Adaptability or versatility
If a simple adhesive delivery mechanism is used, then ease of operation is maintained, but versatility in surgical procedures is limited
Solution Approach 1:
The adhesive delivery system is designed with universal applicability across multiple surgical procedures including conventional, endoscopic, and robotic-assisted surgeries. The ball-and-socket joint configuration and flexible conduit enable the same device to function effectively in diverse surgical contexts, providing versatility without requiring multiple specialized tools.
Solution Approach 2:
The dynamic capabilities of the system, including pivotal movement and flexible conduit bending, are designed to be intuitively controllable, maintaining ease of operation while dramatically increasing versatility. The natural movement characteristics of the articulated joints allow surgeons to leverage familiar motor skills across different surgical applications.
