Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional remote control techniques (infrared, radio, Bluetooth) are used, then reliable device control is achieved, but transmitter and receiver must be paired and decoding schemes are required, increasing device complexity
Solution Approach 1:
The patent extracts and eliminates the complex decoding scheme and pairing mechanism from conventional remote control systems. By using a counter unit that sequentially activates output terminals based on the number of initiation signals, the system removes the need for programmed control units and decoding algorithms, thereby reducing device complexity while maintaining control reliability
Solution Approach 2:
The patent changes the control parameter from coded signals requiring decoding to pulse count-based control. The counter unit counts initiation signals and converts the count into specific control voltages through the diode/transistor switching network, eliminating the need for complex signal decoding while preserving reliable device control
2Measurement precision
If decoding schemes and programmed control units are implemented, then accurate signal interpretation is achieved, but the overall circuit design becomes complicated
Solution Approach 1:
The counter unit performs self-counting of initiation signals and automatically converts the count into corresponding control voltages through the diode or transistor switching network. This self-service mechanism eliminates the need for external decoding schemes and programmed control units, achieving accurate signal interpretation through simple counting logic rather than complex decoding circuits
Solution Approach 2:
The patent introduces a counter unit as an intermediary between the initiation signal receiver and the control voltage output. This intermediary component translates the number of initiation signals into specific control voltages through sequential activation of diodes or transistors, providing accurate signal interpretation without requiring complex decoding schemes
3Adaptability or versatility
If dedicated remote controllers are designed for different electrical devices, then device-specific control requirements are met, but the number of remote controllers increases
Solution Approach 1:
The patent creates a universal control system where a single remote controller can control multiple different electrical devices. The counter unit generates different control voltages based on the number of initiation signals received, allowing one remote controller to adapt to various devices by simply varying the signal count, thereby eliminating the need for multiple dedicated remote controllers

AI summary
The driver circuit according to the invention includes a receiver module, a counter unit, isolation units and a voltage regulation unit. The receiver module receives an initiation signal and performs filtering using a low-pass filter to convert the initiation signal into a driving signal which is transmitted to the counter unit. Upon receiving the driving signal, the output terminals of the counter unit are sequentially activated to output a control signal. The isolation units may be diodes or transistors adapted to output an isolated control signal. The voltage regulation unit includes a plurality of resistors and is adapted to output a control voltage corresponding to one of the resistors according to the isolated control signal. The control voltage is useful in shifting the operation of an electrical device from one operation state to another.
