Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If field drying is used to prevent mold and spontaneous combustion, then crop safety is improved, but drying time increases and nutrient loss occurs
Solution Approach 1:
The patent combines the drying function with the harvesting machine by integrating a drying chamber and drying elements directly into the harvesting system. This allows the crop to be dried immediately after harvesting within the same machine, eliminating the need for separate field drying processes and reducing the time crops are exposed to environmental risks.
Solution Approach 2:
The drying process is performed preliminarily within the harvesting machine before the crop is deposited in the field. By drying the crop immediately after harvesting and before it is left in the field, the system prevents mold and spontaneous combustion from developing, while also reducing the time the crop is vulnerable to environmental factors.
2Adaptability or versatility
If multiple machines are used for harvesting, drying, and collection, then functional completeness is improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates multiple functions including harvesting, drying, and collection into a single machine system. The harvesting machine includes a drying chamber with drying elements, a collection mechanism, and control systems all combined in one unit, eliminating the need for separate machines for each function and reducing overall system complexity.
Solution Approach 2:
The harvesting machine is designed as a multi-functional system that can perform harvesting, drying, and collection operations. The machine includes adjustable drying elements, controllable drying chambers, and collection mechanisms that can adapt to different crop types and drying requirements, providing universal functionality across various agricultural applications.
3Reliability
If field drying is extended to ensure thorough drying, then moisture control is improved, but nutrient loss and crop quality degradation increase
Solution Approach 1:
The system controls drying parameters such as temperature, air flow, and drying duration within the drying chamber to achieve optimal moisture reduction while preserving nutrients. The control system adjusts these parameters dynamically to prevent excessive drying that would cause nutrient loss, maintaining a balance between moisture control and nutrient preservation.
Solution Approach 2:
The system incorporates sensors and control mechanisms that monitor the drying process in real-time, adjusting drying parameters based on feedback about crop moisture content and environmental conditions. This feedback control prevents over-drying and nutrient loss while ensuring adequate moisture removal to prevent mold and spontaneous combustion.
