Solution Overview

Problem

Agricultural tillage implements face challenges in managing the transition between operating and transport modes, particularly with interference issues in the track system of the hitch components, which complicates the movement and increases the risk of dirt and debris accumulation, leading to potential binding or breakage.

Innovation Solution

A shielded carrier track system integrated into the pull hitch assembly, featuring a tunnel and guide channel that protects and guides the hose carrier track, allowing it to move smoothly and preventing dirt and debris accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a telescoping hitch arrangement is used to convert the implement between transport mode and operational mode, then the implement can be transformed between modes, but the track system experiences interference in movement

Engineering Contradiction:

Improvemode conversion capabilityVSAvoidtrack system movement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

A guide channel is introduced as an intermediary component between the hose carrier track and the tube members. The guide channel receives and guides the hose carrier track, ensuring smooth movement during telescoping operations while preventing interference between the track and other hitch components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the hose carrier track is exposed during telescoping movement, then the track can move freely, but dirt and debris accumulate leading to binding or breakage

Engineering Contradiction:

Improvetrack movement freedomVSAvoidtrack durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A tunnel with flexible or rigid walls is used to enclose and protect the hose carrier track from external contaminants. The tunnel allows the track to move freely within the enclosed space while preventing dirt and debris from entering and causing binding or breakage of the track system.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If the implement width is increased to provide more functions, then the implement capability is improved, but the transport size becomes difficult to manage

Engineering Contradiction:

Improveimplement functionalityVSAvoidtransport width

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The hose carrier track and tunnel are integrated into the telescoping hitch assembly, with the track nested within the tunnel and both moving within the first and second tube members. This nested arrangement allows the implement to maintain a compact transport width while providing the necessary functionality through the telescoping mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A pull hitch assembly for an agricultural implement having a tool bar coupled with and extending transverse to the pull hitch assembly. The pull hitch assembly includes first and second tube members, a hose carrier track and a tunnel. The second tube member is partially slidingly disposed within the first tube member. The hose carrier track is operatively coupled to both the first tube member and the tube second member. The tunnel is coupled to the first tube member. At least part of the hose carrier track is movable within the tunnel as the first tube member and the second tube member are moved relative to each other.
