Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If mechanical transmission system is used to drive agricultural platform elements, then the system is robust and simple, but the automation level and individual control capability are limited
Solution Approach 1:
The patent replaces the traditional mechanical transmission system with an electrical drive system consisting of independent electric motors for each platform element (cutting system, side conveyor belts, central conveyor belt, and auger). This substitution enables individual speed control and direction reversal of each element through electronic control, significantly increasing automation level while maintaining system robustness through the simplicity of electric motor control architecture.
2Adaptability or versatility
If mechanical transmission from combine harvester is used, then the structure is simple, but the individual speed adjustment capability of each platform element is lost
Solution Approach 1:
The patent segments the drive system by assigning independent electric motors to each functional element of the agricultural platform (cutting system, side conveyor belts, central conveyor belt, and auger). This segmentation allows each element to be controlled independently with adjustable speed and direction, enabling adaptation to different crop types and harvesting conditions, while the modular structure keeps the overall system manageable.
Solution Approach 2:
The patent implements dynamic control capability by enabling independent speed adjustment and direction reversal of each platform element through electronic control of electric motors. This dynamic adaptability allows the system to optimize performance for different crop types, moisture conditions, and harvesting requirements, transforming a static mechanical transmission system into a dynamically adjustable electrical drive system.
3Ease of operation
If electrical drive system with multiple independent motors is implemented, then individual control of each element is achieved, but the system complexity increases
Solution Approach 1:
The patent employs a universal control module that manages all electric motors driving the platform elements (cutting system, side conveyor belts, central conveyor belt, and auger). This single control module provides multi-functional capability by enabling independent speed control, direction reversal, and coordinated operation of all motors, thereby achieving high operational flexibility without proportionally increasing control system complexity.
