Solution Overview

Problem

Existing vibrating screening systems have long constructive lengths, making transportation and space requirements complicated and expensive, and are sensitive to material loading, which affects conveying efficiency.

Innovation Solution

A vibrating screening system where all supports of the last screening machine are on the surface, with intermediate machines' discharge ends supported by the feed end of the next machine, allowing for reduced distance and weight, and adjustable configurations for different screening tasks and materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple screening machines are arranged in a row with independent supports on the supporting surface, then each machine operates independently with stable support, but the overall system length increases and transport becomes complicated and expensive

Engineering Contradiction:

Improveoperational stabilityVSAvoidsystem length

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent combines the support functions of multiple screening machines by having intermediate machines rest on the feed end of the next machine in the row. This merging of support structures reduces the number of independent supports needed and shortens the overall system length while maintaining operational stability through the interconnected configuration.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple screening machines are arranged in a row with independent supports, then each machine has sufficient support, but the space requirement at the location of use increases

Engineering Contradiction:

Improvesupport stabilityVSAvoidspace requirement

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

By having intermediate screening machines rest on the feed end of subsequent machines, the support footprint is consolidated. This merging approach reduces the overall area occupied by the screening system while maintaining adequate support stability for each machine through the interconnected arrangement.

Inventive Principle:

Principle #5Merging (Combining)

3Length of stationary object

If screening machines are positioned closer together to reduce system length, then transport and space requirements improve, but the machines become more sensitive to material loading

Engineering Contradiction:

Improvesystem lengthVSAvoidloading sensitivity

Core Design Contradiction:

Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The feed end of each subsequent machine serves dual functions: as the discharge end for the previous machine and as the support base for that previous machine. This multi-functionality allows closer positioning of machines while the combined weight distribution across the row reduces individual machine sensitivity to material loading.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If independent screening machines are used, then each machine can be optimized for its specific task, but the overall device complexity increases

Engineering Contradiction:

Improvetask optimizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

While each screening machine maintains its specific screening function and can be optimized for particular tasks, the standardized support arrangement where machines rest on each other creates a modular system. This reduces overall complexity by establishing a uniform structural pattern that simplifies installation, operation, and maintenance compared to fully independent machines with separate support systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A vibrating screening system, made up of at least two screening machines configured in a row and that can be set into vibration, each screening machine having a resiliently supported screening material feed end and a resiliently supported screening material discharge end. All supports of the last screening machine, in the screening material conveying direction, are supported directly on the supporting surface. The support provided respectively in the region of the screening material feed end of any earlier screening machine in the conveying direction is likewise supported directly on the supporting surface. In each case, the support provided in the region of the screening material discharge end of any such earlier screening machine in the conveying direction is supported in the region of the screening material feed end of the screening machine that is subsequent in the screening material conveying direction, on this subsequent machine.
