Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for replacing wear plates in bulk material handling systems require entering the interior space, leading to risks of material falling and damage to fastening elements due to abrasive stress, making replacement difficult and unsafe.

Innovation Solution

A wall design with openings for wear plate fastening elements, allowing for external mounting and replacement without entering the chute, featuring slots and gaps that accommodate the wear plates and fastening bolts, enabling secure and efficient replacement from the outer side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wear plates are fastened from the interior space of the chute, then secure mounting is achieved, but personnel safety deteriorates due to risk of material falling and damage to fastening elements

Engineering Contradiction:

Improvemounting securityVSAvoidpersonnel safety risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional mounting approach by enabling fastening operations to be performed from the exterior side of the wall rather than from the interior chute space. The wall includes openings that allow fastening elements to be inserted and secured from outside, eliminating the need for personnel to enter the hazardous interior space while maintaining secure mounting of wear plates

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If wear plates are replaced by entering the chute interior, then direct access to fastening elements is achieved, but replacement time increases due to safety procedures and difficult access

Engineering Contradiction:

Improveaccess to fastening elementsVSAvoidreplacement time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The wall is segmented with specific openings positioned at convenient exterior locations that provide direct access to fastening elements. These openings allow operators to insert and manipulate fastening elements from outside the chute, eliminating the need to enter the interior space and significantly reducing replacement time while maintaining ease of operation

Inventive Principle:

Principle #1Segmentation

3Strength

If conventional mounting systems are used, then wear plates can be secured, but the structure becomes complex requiring interior access for maintenance

Engineering Contradiction:

Improvefastening capabilityVSAvoidmounting system complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The wall structure is designed with multi-functionality, serving both as the containing structure and as the mounting platform for wear plates. The openings in the wall serve dual purposes: maintaining structural integrity while enabling exterior access for fastening operations. This universal design simplifies the overall system by eliminating separate interior mounting mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wall (2), for receiving one or more wear plates (1), has openings for receiving at least some of the fastening elements (11, 12) of the wear plates (1). The wall has, furthermore, gaps (22), with dimensions corresponding to the width and thickness of the wear plates (1). Slots (23) extend from the gaps (22). The slots (23) correspond to the fastening elements (11, 12) of the wear plate (1). The fastening elements (11, 12) of the wear plates (1) can pass through the wall (2), through the slots (23).
