Agricultural Attachment Device Dual Coupling Receptacles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural attachments are limited in their ability to be easily connected to agricultural vehicles in different variants, as they are either designed for direct coupling to three-point coupling devices or quick-coupling frames, but not both, restricting flexibility and optimal positioning.
Innovation Solution
The attachment device features first receptacles for direct coupling to three-point coupling devices and second receptacles for indirect coupling via a quick-coupling frame, allowing for connection in both configurations with minimal positional difference, ensuring optimal alignment and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an attachment is designed for direct coupling to the three-point coupling device, then the connection is simple and direct, but the attachment cannot be connected to a quick-coupling frame
Solution Approach 1:
The attachment device is designed with both first receptacles for direct coupling to three-point coupling device links and second receptacles for indirect coupling via quick-coupling frame, enabling a single attachment to function with multiple coupling systems. This multi-functional design resolves the contradiction by making the attachment universally compatible without requiring separate attachment devices for different coupling types.
Solution Approach 2:
The attachment device is segmented into distinct first receptacles and second receptacles, each optimized for specific coupling methods. The first receptacles engage directly with coupling links while the second receptacles interface with quick-coupling frames. This segmentation allows each component to be specialized for its function while working together to achieve overall versatility.
2Ease of operation
If different attachment types are used for direct and indirect coupling, then each coupling method has optimized positioning, but the relative position of the attachment to the vehicle varies significantly
Solution Approach 1:
The first and second receptacles are designed with specific geometric parameters and spacing relationships that compensate for the different coupling paths. By carefully controlling the dimensions, angles, and relative positions of the receptacles, the design ensures that both direct and indirect coupling methods result in the attachment being positioned within acceptable tolerances (150 mm longitudinal, 100 mm vertical) relative to the vehicle.
3Adaptability or versatility
If a single attachment device is designed to accommodate both direct and indirect coupling, then versatility is improved, but the device complexity increases
Solution Approach 1:
The first receptacles and second receptacles are merged into a single integrated attachment device structure. This consolidation allows the attachment to access both direct and indirect coupling methods without requiring separate devices, thereby achieving versatility while managing complexity through unified design rather than multiple independent systems.
