Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single sensor is used to detect positional states, then the device complexity is reduced, but the reliability of sensor state management deteriorates due to unintended activation during positional changes
Solution Approach 1:
The patent divides the sensing function into multiple sensors positioned at different locations. Each sensor detects positional states from its specific viewpoint, and the system segments the detection task across multiple sensing elements to achieve more reliable state determination and prevent unintended activation.
Solution Approach 2:
The patent combines multiple sensor readings to determine the overall positional state. By merging the detection results from multiple sensors, the system achieves more reliable state management and reduces false activations that would occur with a single sensor.
2Measurement precision
If multiple sensors are used to improve detection accuracy, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by disabling sensors that are not needed for the current positional state. Before detecting positional changes, the system proactively disables irrelevant sensors, which simplifies the active sensor set and reduces management complexity while maintaining detection precision with only the necessary sensors active.
Solution Approach 2:
The patent implements dynamic sensor management where the active sensor set changes based on the detected positional state. Sensors are dynamically enabled or disabled according to the current configuration, allowing the system to maintain high measurement precision with a variable, optimized number of active sensors rather than a fixed complex array.
3Reliability
If sensors remain continuously enabled to ensure detection coverage, then the reliability of detection is improved, but the loss of energy increases
Solution Approach 1:
The patent implements periodic sensor activation based on positional state changes rather than continuous operation. Sensors are enabled periodically when positional changes are detected and disabled during static periods, maintaining detection reliability during transitions while reducing energy consumption during stable states.
Solution Approach 2:
The system performs preliminary action by disabling sensors in advance when the system enters a stable positional state. By proactively turning off sensors when no positional changes are expected, the system maintains detection reliability during critical transitions while minimizing energy loss during prolonged static periods.
