Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual mechanical adjustment of detent positions is used, then the system structure remains simple, but the positioning precision and flexibility are limited
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated control system comprising position-ascertaining devices (sensors), control units, and braking devices. This substitution eliminates the need for manual detent adjustment while achieving precise positioning through automated feedback control, directly resolving the contradiction between positioning precision and system complexity.
Solution Approach 2:
The system enables self-positioning through automated detection and adjustment. The position-ascertaining device continuously monitors component positions, and the control unit automatically activates braking devices to maintain optimal positioning without requiring manual intervention, thereby improving precision while keeping operational complexity low.
2Ease of operation
If manual adjustment of detent positions is required, then the device structure is simpler, but the ease of operation deteriorates
Solution Approach 1:
Manual mechanical adjustment is replaced with an automated system that uses position sensors and control units to detect and adjust component positions automatically. This eliminates the need for operators to manually adjust detents, significantly improving ease of operation despite the increased electronic system complexity.
Solution Approach 2:
The system incorporates position-ascertaining devices that provide continuous feedback to the control unit about component positions. The control unit processes this feedback and automatically activates braking devices to maintain optimal positioning, creating a closed-loop control system that simplifies operation while achieving precise positioning automatically.
3Adaptability or versatility
If fixed detent positions are used, then the device structure is simpler, but the adaptability for different examinations deteriorates
Solution Approach 1:
The system transitions from fixed detent positions to dynamic, programmable stop positions. The control unit can be programmed with different stop positions for various examination types, allowing the system to adapt to different medical procedures. This dynamic positioning capability significantly improves versatility while the programmable nature keeps the system manageable despite increased complexity.
Solution Approach 2:
The automated positioning system serves multiple examination types through programmable stop positions. A single system can be configured for different examination requirements by loading appropriate position parameters into the control unit, eliminating the need for multiple dedicated systems and thereby improving adaptability without proportionally increasing physical complexity.
4Speed
If automated positioning with sensors and braking devices is implemented, then positioning precision and speed improve, but mechanical wear increases
Solution Approach 1:
The system replaces continuous mechanical adjustment mechanisms with an automated system that uses electronic sensing and controlled braking. Positioning is achieved through precise electronic control rather than continuous mechanical engagement, significantly reducing mechanical wear while enabling rapid positioning through automated actuation of braking devices.
Solution Approach 2:
The braking devices are activated periodically or intermittently only when positioning adjustments are needed, rather than maintaining continuous mechanical engagement. This periodic activation reduces cumulative mechanical wear while still achieving rapid positioning when required, balancing speed improvement with wear reduction.
