Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to control different processes of the harvest machine, then the control precision and functionality are improved, but the assembly and maintenance effort increases
Solution Approach 1:
The NIR sensor device is designed to perform multiple measurement functions simultaneously - it determines both the moisture content and starch content of the harvest material, and this information is used to control multiple different processes including the chopper drum speed and the silage agent injection system. This multi-functional approach allows one sensor to replace what would traditionally require multiple separate sensors and measurement systems.
Solution Approach 2:
The patent combines the NIR sensor device with the online data processing device into an integrated control system. The sensor device and data processing device work as a unified system to simultaneously measure multiple parameters and control multiple processes, reducing the need for separate sensor systems for each control function.
2Adaptability or versatility
If multiple sensors are installed to monitor harvest parameters, then the measurement capability is improved, but the cost and complexity of the system increases
Solution Approach 1:
The NIR sensor device serves multiple measurement purposes by determining different ingredients and properties of the harvest material simultaneously. It can measure moisture content, starch content, and other parameters, providing versatile measurement capability through a single multi-functional sensor system rather than requiring separate sensors for each parameter.
Solution Approach 2:
The system utilizes the NIR sensor's ability to detect changes in different physical and chemical parameters of the harvest material (moisture, starch, etc.) and translates these measurements into control signals for adjusting harvest parameters. This allows a single sensor to monitor multiple parameters by detecting changes in light absorption and reflection properties.
