Solution Overview

Problem

Current mobile aggregate processing apparatuses face challenges in efficiently adjusting and repositioning conveyors, leading to inefficiencies in material transfer, increased risk of material spillages, and potential damage due to complex setup requirements and limited adjustability, which complicates the flow of aggregate material and increases downtime.

Innovation Solution

A mobile aggregate processing apparatus featuring a slider-crank linkage that connects the first and second conveyors, allowing the first conveyor to slide and the second conveyor to rotate, enabling tandem movement and easier positioning, thus improving the alignment and efficiency of the transfer point.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the first conveyor is fixed to the chassis to withstand receiving forces, then structural stability is improved, but the ability to adjust and reposition the conveyor is worsened

Engineering Contradiction:
Improvestructural stabilityVSAvoidadjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The first conveyor is made dynamically adjustable through a slider-crank linkage mechanism that allows it to move between fixed and repositioned states. The linkage includes a slider that moves along a guide way on the chassis, enabling the conveyor to adapt its position while maintaining structural integrity through the mechanical connection.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the first conveyor is made adjustable to improve positioning flexibility, then adaptability is improved, but device complexity and risk of damage are worsened

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidsetup complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slider-crank linkage mechanism enables the first conveyor to be repositioned through its own structural mechanics rather than requiring external equipment or complex assembly procedures. The slider moves along the guide way using the existing mechanical framework of the apparatus, making the adjustment process self-contained and reducing overall system complexity.

Inventive Principle:
Principle #25Self-service

3Productivity

If the conveyors are carefully positioned to prevent material spillages, then material transfer efficiency is improved, but setup time and operational complexity are worsened

Engineering Contradiction:
Improvematerial transfer efficiencyVSAvoidsetup time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The slider-crank linkage allows the first conveyor to be dynamically repositioned along the guide way to achieve optimal alignment with the second conveyor. This dynamic adjustment capability enables quick repositioning without complex setup procedures, reducing setup time while maintaining efficient material transfer alignment.

Inventive Principle:
Principle #15Dynamics
