Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medical devices are used in minimally invasive procedures, then access to target treatment sites is improved, but control and positioning difficulty increases
Solution Approach 1:
A handle assembly is introduced as an intermediary device between the user and the medical device. The handle assembly includes a control member that can be manually operated to translate into movement of the medical device's articulation mechanism, providing intuitive control without direct manipulation of the complex device components.
Solution Approach 2:
The patent replaces complex direct mechanical control systems with a simplified handle assembly that uses translation mechanisms. The control member's linear movement is converted through mechanical linkages into the desired positional changes of the medical device, making the control system more intuitive and easier to operate.
2Productivity
If complex procedures are performed, then treatment effectiveness is improved, but procedure duration increases
Solution Approach 1:
The handle assembly is pre-configured with the control member and articulation mechanism before the procedure begins. This preliminary setup allows for rapid deployment and immediate use during the procedure, eliminating setup time and reducing overall procedure duration while maintaining complex treatment capabilities.
3Measurement precision
If direct manipulation of medical devices is used, then positioning precision is improved, but risk of injury increases
Solution Approach 1:
The handle assembly serves as a protective intermediary that isolates the user from direct contact with the medical device's critical components. This intermediary structure reduces the risk of injury to both the user and the device while maintaining precise positioning control through the control member's articulated movements.
4Ease of operation
If intuitive control mechanisms are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distinct functional components: the handle assembly with the control member, the articulation mechanism, and the medical device body. This segmentation allows each component to be optimized independently - the handle assembly provides intuitive control while the articulation mechanism handles the complex transformation of movements, reducing overall device complexity.
