Solution Overview

Problem

Conventional lateral-move irrigation systems face limitations in hose length, requiring multiple hydrants and manual hose manipulation, which is labor-intensive and prone to hose damage due to their weight and susceptibility to kinking.

Innovation Solution

A hose-fed lateral move irrigation system with a movable cart equipped with onboard winches that pull a hose assembly in an alternating fashion, allowing the cart to pull double the length of hose and enabling automated operation by connecting to a single hydrant, using a combination of flexible and rigid hoses with expansion-compression zones to facilitate movement without transferring force between hose sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If conventional hoses are used in lateral-move irrigation systems, then the system can be simple in structure, but the hose length is limited and requires multiple hydrants and manual manipulation

Engineering Contradiction:
Improvehose lengthVSAvoidsystem complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The hose assembly is divided into multiple sections that can be independently managed. The system uses a first hose and a second hose that can be selectively connected to hydrants, allowing the cart to service longer distances by segmenting the total hose length into manageable sections that are pulled and connected sequentially.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system pre-positions multiple hydrants along the cart path before irrigation begins. This allows the cart to connect to the next hydrant in advance before the current hose becomes fully extended, enabling seamless transitions and continuous operation without stopping the irrigation process.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If conventional manual hose manipulation is used, then the system structure can be simple, but labor intensity increases and hose damage occurs

Engineering Contradiction:
Improveease of hose handlingVSAvoidtime for hydrant changes
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The irrigation cart is equipped with automated mechanisms including winches and hose manipulation devices that perform hose pulling, connecting, and disconnecting operations automatically. The system self-manages the complex tasks of hose handling, reducing dependency on manual labor and enabling continuous automated operation throughout the irrigation process.

Inventive Principle:
Principle #25Self-service

3Strength

If heavier conventional hoses are used, then hose strength and durability improve, but hose weight increases making manual manipulation difficult

Engineering Contradiction:
Improvehose strengthVSAvoidhose weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The system replaces manual mechanical handling of heavy hoses with automated mechanical systems mounted on the cart, including winches and hose manipulation devices. These automated mechanisms provide the necessary force to handle heavy-duty hoses without requiring manual labor, enabling the use of stronger, more durable hoses that can withstand the demands of long-distance irrigation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Weight of moving object

If lighter-weight hoses are used to reduce weight, then ease of handling improves, but susceptibility to kinking and blockage increases

Engineering Contradiction:
Improvehose weightVSAvoidhose reliability
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The automated winch and hose manipulation systems on the cart provide controlled tension and positioning that prevents kinking and blockage in lighter-weight hoses. These mechanisms ensure that lighter hoses are handled properly throughout deployment and retrieval, maintaining their reliability despite reduced weight by eliminating the manual handling issues that cause kinking.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

5Length of moving object

If the cart stops frequently for hydrant changes, then hose length can be managed, but productivity decreases

Engineering Contradiction:
Improveeffective hose lengthVSAvoidirrigation speed
Core Design Contradiction:
Length of moving objectVSProductivity

Solution Approach 1:

Multiple hydrants are pre-positioned along the cart path, and the system is configured to connect to the next hydrant in advance before the current hose becomes fully extended. This allows seamless transitions between hydrants without stopping the cart or interrupting the irrigation process, maintaining continuous productivity while managing effective hose length.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The automated hose manipulation and hydrant change systems operate continuously without interrupting the irrigation process. The cart maintains constant forward motion while hoses are automatically pulled, connected, and disconnected, ensuring that the useful action of irrigating crops continues uninterrupted and maximizing productivity.

Inventive Principle:
Principle #20Continuity of useful action
