Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency modulation is applied to audio signals, then performance consistency across varying appliance components is improved, but device complexity increases
Solution Approach 1:
The patent applies frequency modulation to audio signals, dynamically changing the frequency parameter of the signal based on detected appliance characteristics. This allows the system to adapt to manufacturing variations in components like loudspeakers without requiring complex hardware modifications, thereby improving performance consistency while managing complexity through software-based parameter adjustment
2Duration of action of moving object
If larger batteries or rechargeable battery systems are used, then operation duration during power failures is extended, but device weight and volume increase
Solution Approach 1:
The system performs preliminary detection of power failure conditions and automatically switches to battery-powered operation before complete power loss occurs. The microprocessor monitors power supply status and pre-activates power management modes that extend operational duration during outages, reducing the need for excessively large batteries while ensuring continuous operation
3Measurement precision
If microprocessors are used for accurate timekeeping, then timekeeping accuracy is improved, but device complexity and power consumption increase
Solution Approach 1:
The microprocessor performs timekeeping functions through periodic synchronization with external time sources rather than continuous independent operation. The system periodically checks and adjusts the time display based on power supply status and external signals, maintaining accurate timekeeping while minimizing power consumption by avoiding constant high-precision operations during power failures
4Measurement precision
If unique identifiers are implemented for IoT device association, then device identification accuracy is improved, but device complexity increases
Solution Approach 1:
The system uses unique identifiers that can be copied and transmitted between devices through standard communication protocols. Rather than implementing complex cryptographic authentication systems, the patent employs straightforward identifier copying and matching mechanisms that achieve accurate device identification while keeping the communication system simple and易于实施
