Solution Overview

Problem

Existing bristle bundle separating devices have imprecise notch volumes, leading to inconsistent bristle filament counts and necessitating time-consuming reworking or remanufacturing of separating discs due to factors like filament structure, material properties, and environmental conditions.

Innovation Solution

A separating device with an adjustment mechanism that allows for precise adjustment of the effective notch volume of separating notches, enabling individual control over the number of bristle filaments per bundle by using movable adjustment means and displacement mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the effective notch volume of the separating notches is fixed during manufacturing, then the separating device structure is simple, but the number of bristle filaments per bundle cannot be precisely controlled and varies due to material properties and environmental conditions

Engineering Contradiction:
Improvenumber of bristle filaments per bundleVSAvoidseparating device structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the separating notches adjustable rather than fixed. The adjustment device allows the effective notch volume to be changed dynamically during operation, enabling precise control of bristle filament count per bundle while adapting to variations in material properties and environmental conditions without requiring device remanufacturing

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing modification of the effective notch volume parameter through the adjustment device. This enables control over the number of bristle filaments per bundle by changing the geometric parameters of the separating notches, directly addressing the manufacturing precision issue while maintaining a relatively simple device structure

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the separating disc is remanufactured to meet tolerance specifications, then the bristle bundle quality improves, but production time and costs increase

Engineering Contradiction:
Improvebristle bundle qualityVSAvoidproduction time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The adjustment device enables dynamic modification of the separating notches during operation, allowing quality adjustments without stopping production for disc remanufacturing. This eliminates time loss while maintaining or improving bristle bundle quality through real-time parameter optimization

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By enabling parameter changes of the effective notch volume during operation, the system can meet tolerance specifications through adjustment rather than remanufacturing, significantly reducing production time and avoiding quality-related downtime

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If the effective notch volume is increased to accommodate more bristle filaments, then the bristle bundle density increases, but the number of filaments per bundle exceeds tolerance specifications

Engineering Contradiction:
Improvenumber of bristle filaments per bundleVSAvoidfilament count tolerance
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The adjustment device provides dynamic control over the effective notch volume, allowing precise tuning of the number of bristle filaments per bundle within tolerance specifications. This enables optimization of filament quantity without exceeding limits, maintaining manufacturing precision while maximizing bundle content

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables precise parameter adjustment of the effective notch volume to control the number of bristle filaments per bundle within specified tolerances, allowing optimization of filament quantity while maintaining quality standards through controlled parameter variation

Inventive Principle:
Principle #35Parameter changes
