Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple dedicated transmitters are used for various sensors, then each sensor can be processed accurately, but the cost of the monitoring system increases exponentially
Solution Approach 1:
The patent implements a universal transmitter that can process multiple types of sensor signals through software configuration rather than requiring dedicated hardware for each sensor type. The transmitter uses a single amplification circuit and A/D converter that can be dynamically configured via control parameters to handle different sensor signals, achieving multi-functionality without increasing hardware complexity
Solution Approach 2:
The transmitter employs dynamic switching of amplification factors and signal processing parameters based on the type of sensor connected. The control parameters can be adjusted in real-time to match different sensor characteristics, allowing the same hardware to adapt to various measurement requirements without physical reconfiguration
2Measurement precision
If dedicated transmitters are used for each sensor type, then signal processing is optimized, but the production cost and price of transmitters increase
Solution Approach 1:
The transmitter is designed as a universal platform that can serve multiple sensor types through software control. By using a single amplification circuit, A/D converter, and processing unit that can be configured via control parameters, the system achieves the functionality of multiple dedicated transmitters while enabling mass production of a standardized device
Solution Approach 2:
The transmitter uses adjustable control parameters including amplification factors, sampling rates, and signal processing settings that can be modified to suit different sensor types. This parameter-based configuration allows the same hardware to be optimized for different applications without requiring physical changes or re manufacturing
3Productivity
If transmitters operate continuously to process sensor data, then data collection is maintained, but electricity waste occurs and system life shortens
Solution Approach 1:
The transmitter implements periodic sampling and processing of sensor signals rather than continuous operation. The system can be configured to activate at specific intervals or trigger events, allowing the amplification and A/D conversion circuits to remain in low-power states between measurements, significantly reducing energy consumption while maintaining data collection capability
Solution Approach 2:
The transmitter includes preliminary signal conditioning and filtering stages that can operate with minimal power consumption to prepare signals for later processing. This allows the main processing circuits to remain dormant until actually needed, extending system life by reducing wear and energy consumption

AI summary
A method for controlling a transmitter, comprising: awaking and initiating the transmitter by a trigger signal generated by a timer; detecting whether the transmitter receives an input control parameter from outside of the transmitter, and if yes, updating an input control parameter stored in the transmitter by using the received input control parameter; reading the input control parameter currently stored in the transmitter; performing operations based on the read input control parameter so as to control the transmitter to select one sensor signal from a plurality of sensor signals, amplify the selected sensor signal with a gain within a first gain range, and output the amplified sensor signal; and after determining that the transmitter has accomplished a task specified by the read input control parameter, resetting the timer, and entering into a sleeping state until the timer generates the trigger signal.
