Solution Overview

Problem

Current slurry spreading devices face challenges in retracting nozzles to comply with maximum trailer dimensions during transport, leading to productivity constraints and potential accidents due to nozzle detachment and reattachment issues.

Innovation Solution

An articulation device with movable studs and a bracket system allowing the spreader to be raised and locked in different positions, enabling secure attachment and detachment without complete disengagement from the system, ensuring reliable operation and compliance with regulatory dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the spreading nozzle is completely detached from the system for cleaning or filling operations, then accessibility for maintenance is improved, but the risk of loss, theft, or accidents increases and productivity is reduced due to repeated attachment/detachment operations

Engineering Contradiction:
Improveaccessibility for cleaning and fillingVSAvoidrisk of nozzle loss or accident
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The coupling device is divided into two independent parts: a fixed coupling body attached to the tank and a movable coupling element attached to the nozzle. This segmentation allows the nozzle to be independently positioned (detached for cleaning, retracted for transport) while remaining part of the system, eliminating the risk of complete detachment and loss while maintaining operational accessibility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling device acts as an intermediary mechanism between the tank and the nozzle. It provides a controlled connection interface that allows the nozzle to be partially detached or retracted while maintaining system integrity, serving as a mediator that enables maintenance operations without complete separation and prevents accidental loss

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the spreading nozzle is extended beyond maximum permitted vehicle dimensions to increase tank capacity, then productivity is improved, but compliance with road regulations is violated

Engineering Contradiction:
Improvetank capacityVSAvoidcompliance with road regulations
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The coupling device enables dynamic positioning of the spreading nozzle, allowing it to be extended beyond the tank for spreading operations (increasing effective capacity) and retracted to within permitted dimensions for transport. This dynamic adjustment capability resolves the contradiction between productivity and regulatory compliance

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If a lever hinge mechanism is used to pivot the nozzle vertically, then the nozzle can be raised for cleaning or filling operations, but wear on the cleat device may lead to the nozzle falling to the ground

Engineering Contradiction:
Improveability to raise nozzleVSAvoidwear resistance of cleat device
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The coupling element is designed as a robust, easily replaceable component that can withstand wear from repeated positioning operations. While it may experience wear, the design ensures it remains securely connected to the tank through the coupling body, preventing complete detachment and nozzle loss even when wear occurs

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
