Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera on the portable communications terminal is used to determine distance, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that includes image capture components, image processing algorithms, and coordinate system transformation mechanisms. This intermediary layer translates complex image data into accurate distance measurements, resolving the contradiction by adding controlled complexity to achieve precision without requiring the entire system to become unnecessarily complex.
Solution Approach 2:
The patent replaces traditional mechanical or sensor-based distance measurement systems with an optical imaging system. By using camera-based image analysis and computational methods to determine distance, the system achieves high measurement precision while avoiding the complexity of multiple mechanical sensors or sophisticated hardware configurations.
2Reliability
If distance determination is continuously monitored, then reliability is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic distance monitoring through the camera system, capturing images at defined intervals or triggered by specific events during maneuvering operations. This periodic action maintains reliable safety monitoring by continuously checking distance thresholds while consuming energy only when necessary, rather than operating continuously.
Solution Approach 2:
The system incorporates feedback mechanisms where distance measurement results trigger appropriate responses. When the vehicle is detected outside the defined distance threshold, the system provides feedback to interrupt or alert the user, maintaining high reliability for safety-critical conditions while optimizing energy usage by activating full monitoring only when needed.
