Solution Overview

Problem

Existing liquid manure spreaders require complex adjusting mechanisms to pivot and secure spreader arms, making it difficult to achieve a large processing width while ensuring easy folding and secure transport.

Innovation Solution

A liquid manure spreader with a central distributor arm and lateral arms that can be pivoted and adjusted in height using a transversely movable axis within an elongated hole, combined with hydraulic cylinders for easy pivoting and height adjustment, and receiving devices for secure holding during transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex adjusting mechanism is used to pivot and secure distribution arms, then the spreader arms can be securely held in position, but the device complexity increases

Engineering Contradiction:
Improvesecure holding of spreader armsVSAvoidadjusting mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the securing function from a complex adjusting mechanism by using simple receiving devices with holding elements that passively secure the spreader arms in position. The transverse axis is guided in an elongated hole, allowing movement without requiring complex active control systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spreader arms self-secure in the receiving devices through their own weight and geometry. The lateral distributor arms rest on the receiving devices with holding elements that automatically engage when the arms are in the transport position, eliminating the need for complex active securing mechanisms.

Inventive Principle:
Principle #25Self-service

2Length of moving object

If the spreader arms are made foldable to reduce width, then transportation compliance is improved, but the ease of operation decreases

Engineering Contradiction:
Improvespreader widthVSAvoidfolding and unfolding operation
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The patent implements dynamic positioning of the spreader arms through a simple transverse axis guided in an elongated hole, allowing the arms to move between transport and working positions. The receiving devices provide passive guidance and securing, making the dynamic operation simple and intuitive.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spreader system is segmented into a central distributor arm and lateral distributor arms that can independently pivot and fold. Each arm can be operated separately, allowing flexible configuration for transport and working positions without requiring complex coordinated control.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the transverse axis is fixed in position, then the structure is simpler, but the adaptability to different positions is reduced

Engineering Contradiction:
Improveaxis guidance structureVSAvoidadjustment of distribution area
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The transverse axis is made dynamically positionable within an elongated hole that extends vertically. This allows the axis to move between lower and upper positions, enabling adjustment of the distribution area width while maintaining a simple guided structure rather than a completely fixed or complex adjustable mechanism.

Inventive Principle:
Principle #15Dynamics
