Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the signal transmitting interval is short and the signal transmitting frequency is high, then the communication establishment speed is improved, but the battery energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the signal transmission frequency adjustable rather than fixed. The system dynamically switches between a first frequency (lower consumption) when communication is not needed and a second frequency (faster communication) when communication is required, allowing the transmission characteristics to adapt to different operational states and resolve the contradiction between speed and energy consumption
Solution Approach 2:
The patent changes the transmission frequency parameter based on operational requirements. By switching between two distinct frequency parameters (first frequency for power saving, second frequency for fast communication), the system optimizes the balance between communication establishment speed and battery energy consumption according to different usage scenarios
2Use of energy by moving object
If the signal transmitting interval is long, then the battery energy consumption is reduced, but the communication establishment time increases
Solution Approach 1:
The system dynamically adjusts transmission frequency based on whether communication is needed. When communication is not required, it uses the first (lower) frequency to conserve energy. When communication is needed, it switches to the second (higher) frequency to reduce establishment time, thus dynamically resolving the contradiction between energy conservation and time efficiency
Solution Approach 2:
The patent implements periodic action by using different transmission frequencies for different periods or states. The first frequency is used during idle periods for power saving, while the second frequency is activated when communication events occur, creating a periodic pattern of low-power and high-performance operation that balances energy consumption and communication speed
3Productivity
If the analyte detection device is in working state continuously, then the real-time communication capability is improved, but the service life of the device is reduced
Solution Approach 1:
The patent makes the device operational state dynamic rather than continuously active. The system transitions between dormant state (first frequency, lower power) and working state (second frequency, higher power) based on communication needs, allowing the device to maintain real-time communication capability when required while extending service life through periodic low-power operation
Solution Approach 2:
The device employs periodic action by alternating between dormant and working states. During dormant periods, it consumes minimal energy extending service life. When communication is needed, it activates at higher frequency for real-time data transmission, creating a periodic cycle that balances productivity and device longevity
