Solution Overview

Problem

Existing methods struggle with the accumulation of clump-shaped processing target materials, particularly clump-shaped wire scraps, during sieving processes, leading to clogging and reduced efficiency in separation systems.

Innovation Solution

A sieving method using a vibrating sieve with specific screen configurations, including a combination of plate-shaped and comb-tooth-shaped portions, where the length of the flat portion exceeds twice the diameter of the openings and the gap between the comb-tooth-shaped and flat portions is within a certain range, effectively preventing clump-shaped materials from getting caught.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional sieving methods are used to separate processing target materials, then separation of materials is achieved, but clump-shaped wire scraps accumulate and clog the sieve, reducing productivity

Engineering Contradiction:

Improveseparation efficiencyVSAvoidsieve clogging

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies dynamic vibration to the sieve structure, transforming it from a static to a dynamic system. The vibration causes clump-shaped wire scraps to separate and fall through the sieve openings rather than accumulating and clogging, thereby maintaining continuous operation and productivity while preventing reliability issues from clogging

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent specifically employs mechanical vibration as the core mechanism to address sieve clogging. The vibratory motion applied to the sieve surface prevents clump-shaped materials from adhering or blocking the openings, enabling continuous separation operation without interruptions for cleaning or maintenance

Inventive Principle:

Principle #18Mechanical vibration

2Measurement precision

If sieve openings are made smaller to improve separation precision, then material separation accuracy improves, but clump-shaped materials are more likely to get caught and accumulate

Engineering Contradiction:

Improveseparation accuracyVSAvoidaccumulation rate

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

By introducing dynamic vibration to the sieve system, the patent enables the use of smaller sieve openings for improved separation accuracy while preventing the productivity-reducing accumulation of clump-shaped materials. The vibration keeps the sieve surface active, preventing material buildup even with finer mesh sizes

Inventive Principle:

Principle #15Dynamics

3Productivity

If the sieve operates continuously to maximize productivity, then output increases, but clump-shaped materials accumulate and cause interruptions

Engineering Contradiction:

ImproveoutputVSAvoidinterruption time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by continuously vibrating the sieve throughout operation, preventing clump-shaped material accumulation before it can occur. This proactive approach eliminates the need for periodic interruptions to clear clogs, enabling truly continuous operation and maximizing productivity without time losses

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The vibratory action is maintained continuously throughout the sieving process, ensuring that the separation function operates without interruption. This continuous dynamic action prevents material accumulation that would otherwise force periodic stoppages, maintaining uninterrupted productivity

Inventive Principle:

Principle #20Continuity of useful action
