Solution Overview

Problem

Conventional screen panels for vibratory machines face challenges in balancing strength and longevity while maintaining a sufficient open area for material separation, often requiring additional support structures that occupy valuable space and increase weight.

Innovation Solution

The design incorporates a reinforcing structure with intersecting bridge elements covered by a resilient polymer layer, which enhances strength and stiffness, allowing for a higher open area and reduced weight by integrating the polymer layer to define screening apertures and protect the structure from wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If additional support structures are added to increase strength and stiffness, then the structural integrity is improved, but the open area for material separation decreases and weight increases

Engineering Contradiction:

Improvestrength and stiffnessVSAvoidopen area

Core Design Contradiction:

StrengthVSArea of stationary object

Solution Approach 1:

The screen panel uses a composite structure combining a polymer layer with a reinforcing structure consisting of bridge elements. This composite design provides the necessary strength and stiffness while maintaining high open area, as the reinforcing bridge elements are strategically positioned to provide structural support without blocking material flow paths.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The reinforcing structure is segmented into multiple discrete bridge elements rather than using continuous support structures. This segmentation allows the bridge elements to be strategically positioned to provide maximum structural support with minimal interference to the open area, enabling material separation across larger portions of the screen panel surface.

Inventive Principle:

Principle #1Segmentation

2Strength

If additional support structures are added to increase strength and stiffness, then the structural integrity is improved, but the weight increases

Engineering Contradiction:

Improvestrength and stiffnessVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of stationary object

Solution Approach 1:

The composite structure of a polymer layer combined with a reinforcing structure of bridge elements provides high strength-to-weight ratio. The polymer layer provides baseline strength while the strategically positioned bridge elements add stiffness and structural integrity, achieving enhanced mechanical properties without proportionally increasing weight.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The reinforcing bridge elements are positioned locally at critical areas where strength and stiffness are most needed, rather than uniformly distributing support structures across the entire screen panel. This localized reinforcement approach maximizes structural integrity while minimizing added weight.

Inventive Principle:

Principle #3Local quality

3Productivity

If the open area is increased to improve material separation capacity, then the throughput is improved, but the strength and stiffness decrease

Engineering Contradiction:

Solution Approach 1:

The composite structure enables high open area design for improved throughput while the reinforcing bridge elements compensate for the reduced material, maintaining necessary strength and stiffness. The polymer layer and bridge elements work together to distribute stresses across the high-open-area structure.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The bridge elements are segmented and positioned to provide structural support at critical locations while maximizing open area in material flow regions. This segmentation allows the screen panel to achieve high throughput through large open areas while maintaining structural integrity through strategically placed support elements.
