Solution Overview

Problem

The existing soil cultivating machines have complex and costly articulated connections between the central frame and the side support frames, which complicate the transmission of load-bearing forces and require additional components for joint elements.

Innovation Solution

The gear housing of the intermediate gear forms a joint strap, simplifying the structure by eliminating the need for separate joint strap components and using the transmission housing itself as joint elements, thereby reducing complexity and component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate joint strap components are used to connect the central frame and side support frames, then the transmission of load-bearing forces is reliable, but the device complexity and component count increase

Engineering Contradiction:
Improvetransmission of load-bearing forcesVSAvoidarticulated connections structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gear housing is merged with the joint strap function, where the gear housing itself serves as one of the joint straps (specifically the front joint bracket) of the swivel joint. This integration eliminates the need for separate joint strap components while maintaining the load-bearing force transmission capability between the central frame and side support frames.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gear housing is designed to perform multiple functions: it houses the intermediate gear mechanism for power transmission and simultaneously serves as a structural joint element (joint strap) for mechanical connection. This multi-functionality reduces the overall component count while ensuring reliable force transmission through the articulated connections.

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

2Stability of the object's composition

If additional joint elements are provided for the swivel joints, then the structural integrity is maintained, but the manufacturing cost and assembly complexity increase

Engineering Contradiction:
Improvestructural integrity of central frameVSAvoidassembly of joint elements
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The gear housing is combined with the joint element function, where the gear housing itself forms the front joint bracket of the swivel joint. This eliminates the need for additional separate joint elements on the central frame side, simplifying both manufacturing and assembly processes while maintaining structural integrity through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the gear housing forms the joint strap, then the component count is reduced, but the load-bearing capacity requirements for the gear housing increase

Engineering Contradiction:
Improvenumber of componentsVSAvoidload-bearing capacity of gear housing
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The gear housing is designed to fulfill dual roles: transmitting rotational motion through the intermediate gear mechanism and simultaneously bearing loads as a structural joint element. The housing is reinforced and dimensioned to handle both torsional loads from gear operation and tensile/compressive loads from the swivel joint function, ensuring adequate strength for both purposes.

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

AI summary

The machine has a transmission housing that comprises two intermediate shafts arranged on a center frame spaced apart from a central drive shaft. A spur gear is arranged between the central drive shaft and the intermediate shafts in the housing. The rotational axes of the intermediate shafts are coincided with the pivot axes of a pivot joint. The center frame is connected with a side supporting frame through multiple hinge elements provided at the pivot joint of the center frame.
