Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple temperature sensors and complex algorithms are used to determine drying completion, then measurement precision may be improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and utilizes only the essential parameter (intake air temperature) from the complex multi-sensor system. By focusing on a single temperature measurement point at the air inlet, the system eliminates unnecessary sensors and complex algorithms while maintaining drying determination accuracy through the specific temperature change rate threshold method.
Solution Approach 2:
The patent replaces expensive, complex multi-sensor systems with a simple, low-cost single temperature sensor solution. The inexpensive sensor combined with straightforward temperature change rate calculation provides adequate drying determination without the high cost and complexity of multiple sensors and sophisticated algorithms.
2Measurement precision
If multiple temperature sensors are used to improve drying determination accuracy, then measurement precision improves, but manufacturing cost increases
Solution Approach 1:
The patent employs a single inexpensive temperature sensor instead of multiple expensive sensors, significantly reducing manufacturing cost. The simple temperature change rate measurement approach maintains adequate drying determination accuracy while making the system economically viable for mass production.
Solution Approach 2:
The patent extracts only the critical temperature measurement from the air inlet, eliminating the need for multiple expensive sensors. This focused measurement approach reduces manufacturing costs while preserving the essential function of drying determination through intelligent analysis of the single temperature data point.
3Measurement precision
If multiple temperature sensors and complex algorithms are employed, then drying determination accuracy may improve, but the number of factors affecting determination increases leading to more errors
Solution Approach 1:
The patent extracts and monitors only the critical intake air temperature parameter, eliminating numerous other temperature measurement points and associated algorithms. This reduction to a single measurement factor minimizes the sources of potential errors and increases the reliability of drying determination, as fewer components mean fewer failure points.
Solution Approach 2:
Instead of using multiple sensors to cross-validate measurements, the patent inverts the approach by using a single sensor with intelligent analysis of temperature change rate over time. This inversion reduces system complexity and potential error sources while maintaining determination accuracy through the temporal dimension of measurement.
