Engineering Contradiction Analysis
1Use of energy by moving object
If functional circuits are connected in series to the power source, then power consumption is reduced, but voltage levels vary across circuits due to voltage divider effects
Solution Approach 1:
A voltage conversion circuit is introduced as an intermediary between the first and second functional circuits. This converter receives signals from either circuit and adjusts voltage levels based on the respective power supply negative terminal signals, enabling proper signal level translation while maintaining the series power connection topology.
Solution Approach 2:
The voltage conversion circuit dynamically changes voltage parameters by converting signal voltage levels according to the potential differences between power supply terminals. This allows the system to adapt voltage levels to match the specific requirements of each functional circuit while operating from a series power source.
2Device complexity
If functional circuits are connected in series, then device complexity is reduced, but signal conversion between circuits becomes complicated
Solution Approach 1:
The voltage conversion circuit is designed to receive signals from either the first or second functional circuit and perform appropriate voltage conversion regardless of the source. This multi-functional capability simplifies the overall system by providing a universal signal translation mechanism that works bidirectionally between circuits operating at different voltage levels.
3Stability of the object's composition
If parallel power supply connection is used, then voltage levels are stable across circuits, but power consumption increases
Solution Approach 1:
The power supply system is segmented into series-connected power sources for different functional circuits, allowing each circuit to operate from its own power supply segment while collectively reducing total power consumption compared to a parallel configuration.

AI summary
An integrated circuitry includes a first circuit, a second circuit, and a voltage conversion circuit. A first power supply positive terminal of the first circuit is electrically coupled to a power source. The second circuit is electrically coupled in series with the first circuit and the power source. A second power supply positive terminal of the second circuit is electrically coupled to a first power supply negative terminal of the first circuit. The voltage conversion circuit is electrically coupled between the first circuit and the second circuit so as to receive a signal from the first circuit or the second circuit. The voltage conversion circuit converts a voltage value of the signal according to a first low potential signal of the first power supply negative terminal and a second low potential signal of a second power supply negative terminal.
