Solution Overview
Problem
Existing agricultural attachment connecting structures for tractors are complex and specialized, limiting their universal applicability and efficiency in combining multiple attachments during a single tractor trip.
Innovation Solution
A supporting structure with a frame, cross members, and side supports that includes coupling units and a coupling device for attaching multiple agricultural attachments, featuring adjustable height and non-standard mechanical connections to ensure secure, road-traffic-approved combinations of tractor, supporting structure, and attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing specialized connecting structures are used for each agricultural attachment, then the connection is secure and stable, but the device complexity increases and universal applicability decreases
Solution Approach 1:
The patent applies universality by designing a single supporting structure with standardized coupling units that can connect multiple different agricultural attachments to a tractor three-point linkage. The structure includes universal coupling units (lower coupling units 9, upper coupling unit 12) that can accommodate various attachments through standardized interfaces, eliminating the need for specialized connecting structures for each attachment type while maintaining secure connections
Solution Approach 2:
The patent applies segmentation by dividing the connecting structure into modular components: a frame (20), multiple lower coupling units (9), an upper coupling unit (12), and a drawbar (30). Each component can be independently manufactured, adjusted, and replaced. The lower coupling units can be positioned at different heights and locations, allowing flexible configuration for different attachment combinations while simplifying the overall system design
2Productivity
If multiple agricultural attachments are combined on a single tractor, then productivity increases, but the ease of operation and adjustment decreases
Solution Approach 1:
The patent applies dynamics by making the lower coupling units height-adjustable along the side supports (4) and allowing the drawbar (30) to be positioned at different locations on the frame (20). This dynamic adjustability enables operators to optimize the configuration for different attachment combinations and operational conditions, maintaining ease of operation while combining multiple attachments for increased productivity
Solution Approach 2:
The patent applies preliminary action by providing a pre-configured supporting structure with all necessary coupling units and adjustment mechanisms in place before attachments are mounted. The structure is designed to accommodate various attachment types and configurations, allowing operators to simply attach the desired attachments without complex setup or modification, thereby maintaining ease of operation while enabling multiple attachments
3Ease of operation
If standardized coupling units are used for three-point connection, then ease of operation improves, but adaptability to different attachment types decreases
Solution Approach 1:
The patent applies local quality by providing multiple lower coupling units (9) at different heights and positions on the frame (20), with each coupling unit capable of being independently adjusted and configured. The side supports (4) allow vertical adjustment of coupling units, while the cross members (2, 3) provide horizontal positioning options. This localized variability within a standardized structure enables adaptation to different attachment types while maintaining ease of operation through standardized coupling mechanisms
