Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile variable sloped vibrating screens operate over a range of 10 to 20 degrees of inclination, then they maintain structural stability and ease of operation, but they cannot function as horizontal screen plants, limiting their adaptability

Engineering Contradiction:

Improveoperating angle rangeVSAvoidsupport mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic support mechanism that allows the screen to transition between horizontal (0 degrees) and variable sloped positions. The support system includes adjustable legs with locking mechanisms that enable the screen to be positioned at different angles, transforming a static structure into a dynamic one that adapts to various operating conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The screen plant is designed to perform multiple functions by operating at different angles. The same equipment can function as a horizontal screen plant (0 degrees) for certain applications and as a variable sloped screen (10-20 degrees) for other applications, eliminating the need for separate equipment for different screening needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the screen is designed for horizontal operation (0 degrees), then it expands application versatility, but it requires a more complex support mechanism to achieve and maintain variable angles

Engineering Contradiction:

Improvehorizontal operation capabilityVSAvoidangle adjustment operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support mechanism incorporates self-adjusting features where the screen can be positioned and locked at desired angles through simple operational inputs. The system includes automatic level detection and adjustment capabilities that reduce the manual effort required to achieve precise horizontal or angled positions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces intermediary components such as adjustable support legs with intermediate positioning stops and locking mechanisms that facilitate easy angle changes. These intermediaries act as mediators between the screen body and the ground, simplifying the operation of angle adjustment while maintaining precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If mobile variable sloped vibrating screens are limited to 10 to 20 degrees inclination, then the support structure remains simple, but multiple screen plants are needed to cover horizontal screening applications

Engineering Contradiction:

Improvesupport structure simplicityVSAvoidapplication coverage

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The support structure is segmented into modular components that can be independently adjusted. This segmentation allows the screen to be divided into adjustable sections, enabling it to achieve both horizontal and angled positions while maintaining structural integrity and simplicity in each segment.

Inventive Principle:

Principle #1Segmentation
