Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coupling mechanisms for crop conveyors are difficult and time-consuming to couple and decouple from carrier arms, especially due to the need for manual alignment and the weight of the units, which hinders efficient operation and fuel consumption.
Innovation Solution
A self-guiding coupling mechanism using engageable complementary gendered elements, such as a tapered A-frame configuration, that automatically aligns and locks into place with the assistance of gravity and fastening means, allowing for quick attachment and detachment without additional weight on the carrier arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional coupling mechanisms are used for crop conveyors, then the conveyor can be attached to the carrier arm, but the coupling and decoupling process becomes difficult and time-consuming due to manual alignment requirements
Solution Approach 1:
The coupling mechanism features self-aligning gendered elements where the male element automatically guides itself into the female element during attachment. The tapered geometry enables the elements to self-align and engage without requiring manual positioning or complex alignment procedures, making the system easy to operate and quick to assemble
Solution Approach 2:
The coupling elements utilize tapered (converging) geometry where the male element has a tapered end and the female element has a corresponding tapered opening. This curved/tapered shape enables automatic alignment and smooth engagement as the elements are brought together, eliminating the need for precise manual alignment and reducing assembly time
2Reliability
If the crop conveyor is permanently attached to the carrier arm, then structural stability is maintained, but fuel consumption increases and ground compaction worsens when the conveyor is not needed
Solution Approach 1:
The coupling mechanism divides the attachment system into separable male and female elements that can be quickly engaged and disengaged. This segmentation allows the crop conveyor to be permanently attachable when needed for structural stability, yet easily removable when not needed to reduce weight, fuel consumption, and ground compaction
Solution Approach 2:
The coupling system transitions from a static permanent attachment to a dynamic removable attachment. The quick-coupling mechanism enables the system to adapt its configuration based on operational needs, allowing the conveyor to be attached during crop processing operations and detached during transport or when spreading is required
3Manufacturing precision
If manual alignment methods are used for coupling elements, then alignment precision can be achieved, but the coupling process becomes more complex and requires additional操作步骤
Solution Approach 1:
The tapered geometry of the male and female coupling elements enables automatic self-alignment during the attachment process. The converging shapes guide the elements into proper alignment without requiring manual positioning or complex alignment procedures, achieving precise engagement while keeping the mechanism simple
Solution Approach 2:
The tapered (converging) shape of the coupling elements provides geometric guidance that automatically aligns the male and female elements as they are brought together. This curved geometry ensures precise alignment through the natural convergence of the tapered surfaces, eliminating the need for complex alignment mechanisms

AI summary
A coupling mechanism for coupling a crop conveyor unit 15, for creating a swath behind an agricultural machine, to a mounting structure 10 attached to an agricultural operating unit, e.g. a mower 21. The coupling mechanism consists of gendered elements 65/66, at least one of which is tapered, such that the connection is self-guiding into the engaged configuration. A quick coupling method is described where the conveyor unit 15 is rolled on wheels to locate the male element 11 underneath the female element 12. The mounting structure is raised such that the male element engages the female element and optional locking pins secure the engaged parts together. Quick de-coupling is performed by reversal of the coupling method.
