Existing agricultural fixtures are limited in their versatility, requiring separate units for different operations and lacking self-loading and uniform spreading capabilities, with existing systems failing to ensure consistent material deposition thickness and efficient adaptation to tractor speed.

Innovation Solution

A polyvalent agricultural fixture equipped with a self-loading system, speed detecting system, and crushing system, allowing for multiple agricultural functions, including uniform spreading and self-filling, with a speed-regulated delivery mechanism and integrated crushing system for uniform material deposition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single agricultural fixture is used for multiple operations, then versatility is improved, but device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hopper is designed with multiple dispensing members for different types of agricultural materials (liquid manure/fertilizer, solid granular material, and maize), allowing a single fixture to perform multiple agricultural operations. The fixture can switch between different dispensing functions by activating appropriate members, eliminating the need for separate fixtures for each operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The dispensing system is divided into distinct segments: liquid dispensing members (orifices/injectors), solid material dispensing members (spreading disks/helical blades), and maize dispensing members. Each segment handles specific material types, enabling versatile functionality while maintaining manageable complexity through functional separation.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If conventional dispensing members are used for solid materials, then spreading capability is provided, but uniform deposit thickness cannot be guaranteed

Engineering Contradiction:
Improvespreading capabilityVSAvoiddeposit thickness uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

A sensor system detects the actual deposit thickness on the ground and provides feedback to the control unit. The control unit processes this information and automatically adjusts dispensing parameters (such as dispensing rate, rotor speed, or injector positioning) to maintain uniform deposit thickness, compensating for variations in tractor speed, ground conditions, or material properties.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The dispensing system incorporates dynamically adjustable components including variable speed rotors, adjustable injector positions, and controllable dispensing rates. These dynamic elements allow real-time adaptation to maintain uniform deposit thickness under varying operational conditions, transforming a static spreading system into an adaptive one.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the fixture lacks self-loading capability, then device complexity is reduced, but productivity decreases due to manual filling requirements

Engineering Contradiction:
Improvedevice complexityVSAvoidproductivity
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The fixture incorporates an automatic self-loading system with a loading hopper, conveyor belt, and sensor-activated dispensing mechanism. When the hopper level drops, sensors detect this and automatically trigger the loading mechanism to refill the hopper from the conveyor, eliminating manual intervention and enabling continuous operation without downtime for refilling.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The conveyor belt pre-transports agricultural material to the loading hopper before the dispensing operation begins. This preliminary positioning of material ensures that when dispensing is needed, the self-loading system can immediately refill the hopper without interruption to the agricultural operation, maintaining continuous productivity.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If the spreading system does not detect tractor speed, then device complexity is reduced, but spreading accuracy deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidspreading accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

A speed sensor mounted on the tractor or fixture detects the actual tractor speed during operation. This speed information is fed back to the control unit, which automatically adjusts dispensing parameters (such as rotor speed, dispensing rate, or injector timing) to maintain accurate and uniform material distribution regardless of variations in tractor speed, ensuring precise spreading at any operating velocity.

Inventive Principle:
Principle #23Feedback
