Engineering Contradiction Analysis
1Ease of operation
If the microprocessor and radio frequency circuit are connected in parallel, then the device can operate with both components powered simultaneously, but the power consumption speed increases too fast causing insufficient energy supply for complete data packet transmission
Solution Approach 1:
The patent segments the power supply path by introducing a series connection between the microprocessor and radio frequency circuit, with the first unidirectional conduction component creating distinct power stages. This segmentation allows control over energy flow timing, enabling the system to manage power consumption in discrete phases rather than simultaneous consumption, thereby extending the energy maintenance time from 170 μs to sufficient for complete data packet transmission.
Solution Approach 2:
The patent implements dynamic power management through the series connection configuration and unidirectional conduction component, which enables the radio frequency circuit to be powered only when needed for transmission. This dynamic approach allows the system to switch between low-power microprocessor-only operation and full-power transmission mode, optimizing energy usage based on operational requirements rather than maintaining constant high power consumption.
2Productivity
If the microprocessor and radio frequency circuit are connected in parallel, then both components can be powered simultaneously, but the energy maintenance time is only 170 μs which is insufficient for complete data packet transmission
Solution Approach 1:
The patent applies preliminary action by having the microprocessor generate the data signal before the radio frequency circuit converts it to a wireless communication signal. The series connection ensures that energy is maintained throughout this sequential process, with the unidirectional conduction component preserving energy from the microprocessor's data signal generation through the radio frequency circuit's signal conversion and transmission, extending the energy maintenance time beyond the 170 μs limitation.
Solution Approach 2:
The series connection with unidirectional conduction component creates a continuous energy flow path from the micro-energy voltage through the radio frequency circuit to the microprocessor and back. This continuity ensures that energy is maintained throughout the entire data packet transmission process without interruption, allowing the useful action of data transmission to complete fully rather than being truncated after 170 μs.
3Ease of operation
If the microprocessor and radio frequency circuit are connected in parallel, then the system can function with both components active, but data transmission error rate increases due to insufficient energy supply
Solution Approach 1:
By segmenting the power supply into series-connected stages with unidirectional conduction, the patent ensures that each component receives adequate energy at the appropriate time. The microprocessor receives energy for data signal generation, and the radio frequency circuit receives energy for signal conversion and transmission, with the series connection preventing energy deficiency that would cause transmission errors while maintaining system functionality.
