Solution Overview

Problem

Existing mobile mixing systems for concrete lack efficient and quick assembly and dismantling of portal units, which results in inadequate protection against weather and increased maintenance time.

Innovation Solution

A modular mixing system where transportable modules can be easily connected and disconnected from the portal unit using coupling devices, allowing for quick assembly and dismantling of a housing that protects the portal unit and its components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a complete enclosure with exterior walls and walkways is provided for the gantry unit, then protection against the elements and accessibility for maintenance are improved, but assembly and dismantling time increases significantly

Engineering Contradiction:
Improveprotection against elementsVSAvoidassembly and dismantling time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The enclosure is divided into multiple separate wall sections that can be independently assembled and disassembled. Each wall section functions as a modular unit that can be quickly attached to and removed from the gantry unit, eliminating the need to dismantle a complete integrated enclosure structure.

Inventive Principle:
Principle #1Segmentation

2Strength

If complex attachment structures are used for the enclosure, then structural stability and protection are improved, but assembly complexity and time increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidattachment complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The attachment system is segmented into simple connection points on the gantry unit that correspond to modular wall sections. Each wall section has simplified attachment mechanisms that engage with these connection points, reducing overall attachment complexity while maintaining structural integrity through the distributed modular design.

Inventive Principle:
Principle #1Segmentation

3Loss of time

If the enclosure is omitted to speed up assembly and dismantling, then assembly time is reduced, but protection against the elements is lost

Engineering Contradiction:
Improveassembly timeVSAvoidexposure to elements
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The enclosure system is segmented into modular wall sections that can be selectively assembled only when protection is needed. These sections can be quickly attached to provide immediate protection against elements, and just as quickly removed when assembly speed is the priority, offering flexibility to balance protection needs with assembly time requirements.

Inventive Principle:
Principle #1Segmentation
