Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile terminal is mechanically connected to a safety-related basic-control apparatus, then secure and unique assignment can be achieved, but device complexity increases due to additional position sensors and verification mechanisms
Solution Approach 1:
The patent replaces complex mechanical coupling verification mechanisms with a sensor-based detection system. Position sensors (accelerometers, gyroscopes, magnetometers) detect the mechanical connection state by monitoring characteristic movement patterns and spatial relationships, substituting direct mechanical verification with field-based sensing that reduces mechanical complexity while maintaining reliability
Solution Approach 2:
The patent uses position sensors to create a digital copy or representation of the mechanical connection state. By monitoring positional data and movement correlations between the mobile terminal and basic-control apparatus, the system creates a virtual model of the mechanical coupling that verifies assignment without requiring complex physical verification mechanisms
2Reliability
If position sensors are added to verify mechanical coupling, then unauthorized control is prevented, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent utilizes existing position sensors in mobile terminals (accelerometers, gyroscopes, magnetometers commonly found in smartphones and tablets) for the dual purpose of device orientation control and mechanical coupling verification. This multi-functional use of existing sensors prevents unauthorized control without adding dedicated verification sensors, thereby avoiding increased device complexity and manufacturing costs
Solution Approach 2:
The system uses the mobile terminal's own existing position sensors to verify the mechanical connection. The terminal's built-in sensors automatically detect whether they are properly coupled to the basic-control apparatus through characteristic movement pattern recognition, eliminating the need for separate verification sensors and reducing overall system complexity
