Solution Overview

Problem

Current sorting installations require manual and complex adjustments for article ejection, relying on operator experience, with no reliable measurement for control or automatic error correction, leading to non-reproducible and time-consuming adjustments.

Innovation Solution

A sorting installation equipped with a detector and analyzer system that provides real-time feedback on article trajectories, allowing for automatic adjustment of conveyor operating parameters to ensure correct ejection trajectories, using sensors like cameras, infrared, or ultrasound, and a control system to modify ejection speed, triggering instant, or displacement speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment methods are used for article ejection, then operator experience can guide the adjustment process, but the adjustment is non-reproducible and time-consuming

Engineering Contradiction:
Improveadjustment processVSAvoidadjustment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical adjustment with an automated optical measurement and control system. A detector (camera) captures article trajectories, an analyzer processes the images to determine trajectory parameters, and a control system automatically adjusts conveyor speed and trigger timing, eliminating the need for manual mechanical adjustment while reducing time from minutes to seconds

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a closed-loop feedback system where the detector continuously monitors article trajectories, the analyzer processes trajectory data in real-time, and the control system adjusts ejection parameters based on the analyzed feedback. This automatic feedback loop replaces manual observation and adjustment, making the process both faster and reproducible

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If empirical adjustment methods are used for ejection positioning, then adjustments can be made based on operator feeling, but the adjustment is not reproducible across different installations

Engineering Contradiction:
Improveadjustment flexibilityVSAvoidadjustment reproducibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces subjective manual adjustment with objective automated measurement and control. The detector system objectively measures article positions and trajectories, the analyzer calculates precise trajectory parameters, and the control system reproduces optimal settings across different installations, eliminating operator-dependent variability while maintaining adaptability through automated parameter optimization

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent systematically varies and optimizes ejection parameters (conveyor speed, trigger timing offset) based on measured article characteristics and trajectory requirements. By using automated parameter adjustment based on real measurements rather than fixed empirical values, the system adapts to different article types and installation conditions while ensuring reproducible results

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If no real-time measurement system is used, then the installation can operate without additional sensors, but no reliable reference can be used for control or error detection

Engineering Contradiction:
Improvesystem configurationVSAvoidtrajectory measurement
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces the absence of measurement systems with an optical detection and analysis system. A detector (camera) captures article trajectories, and an analyzer processes images to determine precise trajectory parameters, providing reliable measurement data for control and error detection that was previously unavailable

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary measurement and analysis system between the ejection mechanism and the article trajectory. The detector and analyzer act as intermediaries that capture, process, and provide actionable information about article trajectories, enabling precise control and error detection without directly modifying the ejection mechanism itself

Inventive Principle:
Principle #24Intermediary (Mediator)
