Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing screw adjusting cone crushers are too large to replace shim adjust cone crushers on smaller trailers, necessitating frequent replacement of both the crusher and conveyor systems.

Innovation Solution

A compact screw adjusting cone crusher with a tramp iron relief system positioned entirely on top, featuring internal threads on the lower section and external threads on the bonnet support, allowing for quick material output size adjustments and reduced footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a screw adjusting cone crusher is used, then quick material output size adjustment capability is improved, but the device footprint becomes too large to fit on smaller trailers

Engineering Contradiction:

Improvequick material output size adjustment capabilityVSAvoiddevice footprint

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The tramp iron relief system is repositioned from a side-mounted or bottom-mounted configuration to a top-mounted configuration on the bonnet. This dimensional relocation allows the relief mechanism to occupy vertical space rather than horizontal space, thereby reducing the crusher's footprint while maintaining quick adjustment capabilities through the screw mechanism

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a screw adjusting cone crusher is used, then material output size adjustment capability is improved, but the need to replace both crusher and conveyor system increases operational cost

Engineering Contradiction:

Improvematerial output size adjustment capabilityVSAvoidoperational cost for equipment replacement

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The compact screw adjusting cone crusher is designed with universal mounting capabilities that allow it to be installed on existing trailer and conveyor systems. The top-mounted tramp iron relief system and compact footprint enable the crusher to serve multiple operations and platforms, eliminating the need to replace entire conveyor systems when changing crusher types

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Area of stationary object

If a compact footprint is reduced, then the ability to replace shim adjust cone crusher on existing trailer is improved, but the tramp iron relief system space requirements become more constrained

Engineering Contradiction:

Improvefootprint sizeVSAvoidtramp iron relief system configuration

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The tramp iron relief system is merged with the bonnet structure, integrating the relief mechanism directly into the existing bonnet assembly. This consolidation eliminates the need for separate relief system components and mounting structures, thereby reducing overall footprint while managing system complexity through integration

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A screw adjust cone crusher with a top tramp iron relief system where the bonnet can be vertically adjusted by rotating the threaded bonnet support within the threaded lower section. The tramp iron system is disposed entirely above the bonnet, thereby creating a small footprint screw adjust cone crusher with overhead tramp iron release system.
