Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If optical identification is implemented using a sensing position external to the support system, then the impact on preparation surface functionality is minimized and space requirements are reduced, but the system complexity increases due to the need for reflecting surfaces and optical path management
Solution Approach 1:
A reflecting surface is introduced as an intermediary element to redirect electromagnetic waves from the preparation disc to the external sensing position. This mediator enables the optical sensor to detect identification marks without being positioned directly over the preparation surface, thus minimizing interference with the preparation function while maintaining detection capability.
Solution Approach 2:
The sensing position is moved from a vertical position directly over the preparation disc to an external position adjacent to the support system. By changing the spatial dimension of the sensing location and using the reflecting surface to create an indirect optical path, the system achieves detection capability without occupying space directly over the preparation area.
2Adaptability or versatility
If multiple shelves with multiple preparation discs are supported, then the system becomes more compact and adaptable, but the difficulty of detecting and measuring identification marks increases due to varying positions and orientations
Solution Approach 1:
A single optical sensor is designed to perform multiple detection functions across different shelves. The sensor can detect identification marks on preparation discs located at various positions and orientations by receiving reflected electromagnetic waves, eliminating the need for separate sensors for each shelf and position.
Solution Approach 2:
The reflecting surface acts as a universal intermediary that captures electromagnetic waves reflected from identification marks at various positions and redirects them to the single sensing position. This mediator enables one sensor to effectively monitor multiple locations that would otherwise require multiple sensors.
3Productivity
If automated transfer unit is implemented based on identification output, then productivity and precision are improved, but the device complexity increases due to integration of control and transfer mechanisms
Solution Approach 1:
The control unit receives identification output from the optical sensor and uses this feedback information to automatically control the transfer unit. The feedback loop enables the system to identify the correct preparation disc and automatically transfer it to the mechanical processing unit without manual intervention, improving productivity and precision.
Solution Approach 2:
The control unit and transfer unit are integrated into a unified automated system. The control unit processes identification information and directly controls the transfer unit, merging the decision-making and execution functions into a coordinated automated sequence that reduces operational complexity despite the advanced capabilities.
4Adaptability or versatility
If preparation discs can be placed on any shelf rather than pre-allocated positions, then system flexibility and adaptability are improved, but the reliability of correct disc identification may be compromised without precise positioning
Solution Approach 1:
The reflecting surface serves as a mediator that captures electromagnetic waves from identification marks regardless of their position on any shelf. By redirecting these waves to the sensing position, the system maintains reliable identification capability even when preparation discs are placed flexibly on different shelves rather than at fixed positions.
Solution Approach 2:
The optical sensor and reflecting surface combination creates a universal detection system that can identify preparation discs on any shelf. This multi-functional capability allows the system to handle flexible shelf placement while maintaining accurate identification through the ability to detect marks at various positions and orientations.
