Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If moving elements are operated continuously between extreme positions, then productivity is maintained, but reliability deteriorates due to elements becoming stuck or limited in movement
Solution Approach 1:
The patent applies preliminary action by implementing a testing phase before normal operation begins. The method tests each moving element to verify it can reach both extreme positions and detect potential defects in advance, preventing stuck elements from affecting productivity during continuous operation.
Solution Approach 2:
The patent implements feedback by using an oscillator whose frequency changes based on the position of moving elements. The oscillator provides real-time feedback about element status, allowing the system to detect when elements are stuck or limited in their movement and take corrective action.
2Ease of operation
If standard controlling commands are used to move elements, then ease of operation is maintained, but reliability deteriorates when elements become stuck or limited in movement
Solution Approach 1:
The patent uses feedback from the oscillator frequency to monitor whether moving elements respond correctly to control commands. When an element becomes stuck or limited, the oscillator frequency changes, providing feedback that indicates the element is not responding as expected, allowing the system to detect reliability issues while maintaining simple control operations.
Solution Approach 2:
The patent implements self-service by having the moving elements themselves provide information about their status through the oscillator frequency changes. The elements essentially test themselves by their physical position affecting the oscillator, eliminating the need for separate complex monitoring systems.
3Reliability
If testing of moving elements is implemented, then reliability is improved through defect detection, but device complexity increases due to additional testing mechanisms
Solution Approach 1:
The patent applies universality by making the oscillator serve multiple functions: it acts as both a timing signal generator for the system and a sensing mechanism for detecting moving element positions and potential defects. This multi-functionality reduces the need for separate dedicated testing hardware.
Solution Approach 2:
The patent implements self-service by using the moving elements' own physical positions to modulate the oscillator frequency. The elements essentially test themselves through their impact on the oscillator, eliminating the need for separate complex monitoring systems and reducing overall device complexity.
4Measurement precision
If oscillator frequency measurement is used to determine element state, then measurement precision is improved, but device complexity increases due to electrical coupling requirements
Solution Approach 1:
The patent implements self-service by having the moving elements themselves affect the oscillator frequency through their physical positions changing the electrical coupling. The elements provide their own position information directly to the oscillator, eliminating the need for separate complex measurement systems.
Solution Approach 2:
The patent uses the oscillator as an intermediary that translates the physical position of moving elements into frequency changes. This intermediary approach allows precise position detection without requiring direct complex measurement systems, as the oscillator mediates between the mechanical position and the electrical measurement.
