Solution Overview

Problem

Vibrating screens require different designs of side hold downs for various screening media, necessitating unique fixation means and positions, limiting the versatility and adaptability of screens for different types and sizes of media.

Innovation Solution

An adapter system comprising an insert with parallel grooves and an adapter with parallel ribs, allowing for adjustable positioning and inclination, enabling the same screen to accommodate different screening media without changing the sidewalls or screen design, using a universal insert and adapter system with a snap-lock mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different designs of side hold downs are used for various screening media, then the fixation can be adapted to specific media requirements, but the screen structure becomes complex and requires multiple fixation means at different positions and inclinations

Engineering Contradiction:

Improveadaptability to different screening mediaVSAvoidcomplexity of fixation system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The insert is designed with multiple parallel grooves that can accommodate different adapter configurations, allowing a single insert design to serve multiple fixation requirements for various screening media types, thereby achieving universality and multi-functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fixation system is divided into separate functional components: the insert with grooves and the adapter with ribs. This segmentation allows each component to be optimized independently while maintaining overall adaptability, reducing the complexity of the integrated system

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the screen is designed to accommodate different screening media types, then versatility is improved, but the screen design and sidewalls require multiple configurations

Engineering Contradiction:

Improveversatility for different screening mediaVSAvoidease of screen manufacturing

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The insert design provides a universal mounting solution that can accommodate different screening media types without requiring custom sidewall configurations. The same insert with multiple grooves serves various media requirements, simplifying screen manufacturing while maintaining versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The insert acts as an intermediary component between the fixed sidewall and the variable adapter/hold down assembly. This mediator allows the sidewall to remain simple and standardized while providing adaptability through the insert's multiple groove configurations

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present invention concerns an adapter system for fixing different screening media (14, 22) to a vibrating screen. By means of the adapter system different side hold downs (15, 23) used for different screening media may be fixed to a wall (11) of the vibrating screen without any modifications of the wall (11). The adapter system comprises an insert (1) to be placed in an opening of the wall (11). An adapter (2, 8, 9) is attached to the insert (1) at a desired height in relation to the insert (1). The insert (1) has a number of parallel grooves (4) co-operating with parallel ribs (5) on the adapter (2, 8, 9) in order to attached the adapter (2, 8, 9) to the insert (1).
