Solution Overview
Problem
Agricultural spreaders face challenges in flexibility and complexity, leading to increased costs and operational complexity due to the need for multiple control devices, which can result in hydraulic and pneumatic fluid leaks and difficulty in coupling working units to the pressure supply device.
Innovation Solution
A distribution machine design where a single control unit is connected to the pressure supply device via both a primary control unit and a fan control unit, allowing for adjustable fluid flow and pressure to operate working units in different positions, reducing the need for multiple control devices and simplifying operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate control units are used for different working units, then each working unit can be operated in different positions independently, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple control functions into a single control unit that can independently control different working units. The control unit includes multiple control valves that can be independently actuated, allowing each working unit to be controlled separately while using a single integrated control device, thus reducing overall complexity while maintaining independent operation capability
Solution Approach 2:
The single control unit is designed with multi-functionality to handle multiple working units through different control valves. Each control valve can be independently actuated to control fluid flow to specific working units, enabling the control unit to perform multiple control functions simultaneously or sequentially
2Adaptability or versatility
If multiple separate control units are used for different working units, then each working unit can be operated in different positions independently, but the likelihood of fluid leaks increases
Solution Approach 1:
By merging multiple control functions into a single control unit with integrated fluid conduits, the patent reduces the number of connection points and potential leak sources. The single control unit uses a unified fluid supply system with internal routing, eliminating the need for multiple separate fluid connections that would increase leak risk
3Device complexity
If a single control unit is used for multiple working units, then the device complexity is reduced, but the ability to operate working units in different positions independently is limited
Solution Approach 1:
The control unit is segmented into multiple independent control valves, each capable of being actuated separately to control fluid flow to specific working units. This segmentation allows independent control of each working unit while maintaining a single integrated control device structure
Solution Approach 2:
The control unit incorporates dynamic control capabilities through multiple actuable control valves that can be independently activated or deactivated. This allows the system to dynamically adjust fluid flow distribution to different working units based on operational requirements, enabling independent position control
4Adaptability or versatility
If multiple control units are connected to the pressure supply device, then each working unit can be controlled independently, but the coupling complexity and difficulty increase
Solution Approach 1:
The patent merges multiple control unit connections into a single coupling interface with the pressure supply device. The single control unit includes internal fluid routing that distributes hydraulic fluid to multiple control valves, eliminating the need for multiple separate couplings and simplifying the manufacturing and assembly process
