Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex support system with multiple components (frame, ball joint, frame mounting arm, sliding joint, connecting arm, connector) is used to support medical instruments, then the medical instrument can be positioned and oriented, but the structure becomes complex and difficult to adjust
Solution Approach 1:
The support system is segmented into a modular structure consisting of a support base, support arm, and support rod that can be independently assembled and adjusted. This segmentation allows each component to perform a specific function while maintaining overall system simplicity and ease of adjustment.
Solution Approach 2:
The support arm is designed with universal adaptability to accommodate different medical instruments through standardized connection interfaces. The ball joint and locking mechanism provide multi-functional capabilities for positioning and securing various types of medical devices, reducing the need for multiple specialized components.
2Device complexity
If a simple support structure is used, then the device complexity is reduced, but the ability to properly position and orient medical instruments is compromised
Solution Approach 1:
The support arm incorporates a ball joint with a locking mechanism that enables dynamic positioning. The arm can be freely adjusted to various angles and positions, then locked securely in place. This dynamic capability allows a simple structural design to achieve versatile positioning and orientation of medical instruments.
Solution Approach 2:
The ball joint acts as an intermediary element between the support arm and the medical instrument, providing a universal connection interface that enables proper positioning and orientation. This intermediary component allows the simple support structure to adapt to various medical instruments without requiring complex customization.
