Solution Overview

Problem

Conventional dispersion and supply apparatuses face challenges in achieving uniform conveyance of articles to multiple positions due to uneven article distribution, leading to unstable and non-uniform supply, as the dispersion table's inclination affects conveyance amounts and distribution patterns.

Innovation Solution

A dispersion and supply apparatus equipped with a dispersion table, a driving unit, an acquisition unit for load measurement, a calculation unit for load deviation analysis, and a control unit that adjusts the conveying direction based on load deviations, maintaining a consistent inclination and ensuring uniform distribution across multiple positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the dispersion table is tilted downward to increase conveyance amount at low-distribution portions, then article distribution uniformity is improved, but conveyance amount becomes unstable and non-uniform supply occurs

Engineering Contradiction:
Improvearticle distribution uniformityVSAvoidconveyance amount stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies dynamics by making the conveying direction changeable while keeping the inclination angle fixed. The control unit dynamically adjusts the conveying direction based on real-time load amount detection, allowing the system to adapt to distribution variations without changing the physical inclination, thus maintaining both uniformity and stability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter being controlled from inclination angle to conveying direction. Instead of varying the inclination angle to adjust conveyance, the system varies the conveying direction parameter based on load distribution, achieving uniform supply while maintaining constant inclination and stable conveyance characteristics

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the dispersion table inclination angle is increased to improve article dispersion, then distribution uniformity is improved, but articles are removed from the dispersion table and continuous supply is disrupted

Engineering Contradiction:
Improvearticle distribution uniformityVSAvoidcontinuous supply capability
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system dynamically changes the conveying direction based on detected load distribution rather than using fixed high inclination. This dynamic adjustment allows articles to be redirected to under-supplied areas without removing them from the dispersion table, maintaining continuous supply while achieving uniform distribution

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using detection means to monitor load amounts at different positions and using this information to adjust the conveying direction. This closed-loop control ensures uniform distribution is achieved through real-time adjustments rather than aggressive inclination changes that would disrupt continuous supply

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If the dispersion table is tilted to redirect articles to low-distribution areas, then distribution uniformity is improved, but conveyance amount at opposite positions decreases

Engineering Contradiction:
Improvearticle distribution uniformityVSAvoidconveyance amount at all positions
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent changes the control parameter from inclination angle to conveying direction. By adjusting the direction parameter dynamically, the system can redirect articles to under-supplied areas without creating excessive conveyance at those positions, thereby maintaining balanced distribution across all positions while preserving overall conveyance quantity

Inventive Principle:
Principle #35Parameter changes
