Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If handling machines are equipped with boom and tool-carrying frame to carry out various handling operations, then versatility is improved, but device complexity increases

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

Solution Approach 1:

The handling machine is designed with a universal tool-carrying frame that can accommodate multiple types of tools (buckets, forks, spreaders, etc.) through standardized mounting interfaces. This allows a single machine platform to perform diverse agricultural handling operations including material transport, loading, unloading, and distribution, thereby achieving versatility without proportionally increasing device complexity

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

Solution Approach 2:

The handling machine is divided into modular components: a base chassis, a pivotally mounted boom, and a separate tool-carrying frame that can be independently coupled to different tools. This segmentation allows the tool-carrying frame and attached tools to be swapped out as needed, providing versatility while keeping the core machine structure relatively simple and manageable

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If autonomous coupling module with spatial detection sensors is added to enable autonomous tool coupling, then extent of automation is improved, but device complexity increases

Engineering Contradiction:
ImproveautonomyVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The autonomous coupling module enables the handling machine to perform self-positioning and self-coupling operations without human intervention. The spatial detection sensors automatically detect tool positions and orientations, the control unit processes this information to calculate coupling parameters, and the steering member and motor automatically adjust the machine's position and orientation to achieve precise autonomous coupling with the tool

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical coupling operations with an automated control system that uses spatial detection sensors (optical/electronic) to detect tool positions, processes data through a control unit, and actuates the steering member and motor to achieve coupling. This substitution of manual mechanical operations with sensor-based detection and automated control reduces the need for complex manual intervention mechanisms while achieving high-level automation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
