Solution Overview

Problem

Existing K processing plants require complex and costly mechanisms for adjusting and transporting material fractions from screen decks, including additional transfer belts and hydraulic systems, which increase mechanical complexity and construction volume.

Innovation Solution

A mechanical adjusting device with a pivoting mechanism and four-bar linkage system allows for height and directional adjustment of the transport device, eliminating the need for additional transfer belts and simplifying the design by enabling direct discharge of material fractions onto the transport device, which can then pile them up next to the machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an additional transfer belt is used to transport material from the upper screen deck, then the rock material can be conveyed away from the discharge area, but the number of parts and assembly costs increase significantly

Engineering Contradiction:
Improvematerial discharge capabilityVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transport device is designed to perform multiple functions: it serves as both the discharge conveyor for the upper screen deck and the receiving conveyor for both screen decks. By merging the function of the additional transfer belt into the adjustable transport device, the patent eliminates the need for separate transfer belts while maintaining the capability to discharge material from either or both screen decks.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transport device is made adjustable between different positions to dynamically adapt to different operating modes. It can be positioned to receive material from the upper screen deck only, from both screen decks, or configured to discharge material laterally. This dynamic adjustability replaces the need for fixed additional transfer belts.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If an additional transfer belt is installed to handle material from the upper screen deck, then material transport flexibility is improved, but the overall size of the rock processing plant increases

Engineering Contradiction:
Improvematerial transport flexibilityVSAvoidplant footprint
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The transport device is designed as a universal conveyor that can serve multiple purposes: transporting material from the upper screen deck, from the lower screen deck, or from both decks simultaneously. This multi-functionality eliminates the need for dedicated separate transfer belts, thereby reducing the overall plant footprint while maintaining transport flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the entire screening unit is adjusted vertically to reposition screen decks, then both screen decks can be moved to different positions, but the mechanical complexity and feed unit modifications increase

Engineering Contradiction:
Improvescreen deck positioningVSAvoidadjusting mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of moving the entire screening unit as one complex assembly, the patent segments the adjustment function and applies it only to the transport device. The transport device can be independently adjusted to different positions to receive material from different screen decks, while the screening unit itself remains stationary. This segmentation significantly reduces mechanical complexity.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If a hydraulic cylinder and articulated arm mechanism is used to adjust the transport device, then the transport device can be repositioned, but the mechanical complexity increases

Engineering Contradiction:
Improvetransport device adjustabilityVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transport device incorporates adjustable elements that allow it to dynamically change its position and configuration. The device can be adjusted to different heights and angles to optimize material reception from different screen decks, providing versatility without requiring complex hydraulic systems for the entire screening unit.

Inventive Principle:
Principle #15Dynamics
