Solution Overview

Problem

The discharge conveyor in material processing apparatuses impedes access to other parts, necessitating cumbersome removal procedures for maintenance or replacement of components like the transfer conveyor.

Innovation Solution

A conveyor system with a pivotable coupling mechanism and actuators allows the discharge conveyor to pivot and move linearly, enabling it to transition into an access state that does not obstruct the removal of other components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the discharge conveyor is fixed in position, then it provides stable material discharge function, but it obstructs access to other parts for maintenance or replacement

Engineering Contradiction:
Improveaccess to parts for maintenanceVSAvoidfixed position of discharge conveyor
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The discharge conveyor is made dynamically reconfigurable through a coupling mechanism that allows it to pivot between a working position (for stable material discharge) and an access position (for maintenance of other parts). This dynamic repositioning resolves the contradiction by allowing the conveyor to adapt its position based on operational needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling mechanism separates the discharge conveyor from the main apparatus body, creating an independent movable segment. This segmentation allows the conveyor to be repositioned without affecting the stability of the main apparatus, enabling access to other components while maintaining overall system stability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the discharge conveyor is removed for maintenance, then access to other parts is improved, but the procedure becomes awkward and time-consuming

Engineering Contradiction:
Improveaccess to parts for maintenanceVSAvoidtime for maintenance procedure
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

Instead of complete removal, the coupling mechanism enables quick repositioning of the discharge conveyor to an access position. This dynamic adjustment is significantly faster and less cumbersome than full removal and reinstallation, reducing maintenance time while providing adequate access.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling mechanism serves multiple functions: it enables both the working position for material discharge and the access position for maintenance. This multi-functionality eliminates the need for separate removal procedures, streamlining the maintenance process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the discharge conveyor is pivotable, then access to other parts is facilitated, but the coupling mechanism complexity increases

Engineering Contradiction:
Improveaccess to parts for maintenanceVSAvoidcoupling mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling mechanism is designed as a segmented, modular assembly with discrete components (pivot points, coupling elements, support structures). This segmentation makes the mechanism easier to manufacture, assemble, and maintain, offsetting the complexity introduced by the pivoting capability.

Inventive Principle:
Principle #1Segmentation

AI summary

A material processing apparatus ()10 has a discharge conveyor (30) that is coupled to the body of the apparatus so that it can pivot with respect to the body and be raised vertically with respect to the body. The coupling mechanism allows the pivoting and lifting of the conveyor to be performed by the same actuators (60). The discharge conveyor can be raised into an access state in which a transfer conveyor can be removed from the body.
