Solution Overview

Problem

Existing loading systems for glass tempering furnaces are inefficient and costly due to the need for manual loading, limited flexibility in accommodating glass panels of varying sizes, and the potential for damage from robotic loading systems, leading to suboptimal utilization of conveyor frames and increased energy consumption.

Innovation Solution

A loading system with a conveyor frame equipped with lifting units and individual control of conveying means, allowing for the automatic arrangement of plate-shaped objects of different sizes and orientations on the conveyor frame without altering the position of previously placed objects, using detachable lifting units and separate drive mechanisms for each conveyor section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual loading is used, then flexibility in loading different glass panel sizes is maintained, but labor costs increase and productivity decreases

Engineering Contradiction:
Improveflexibility in loading different glass panel sizesVSAvoidloading speed and efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system uses sensors to automatically detect glass panel dimensions and the control unit autonomously determines optimal positioning, eliminating the need for manual measurement and decision-making while maintaining adaptability to different panel sizes

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual loading operations are replaced by an automated system combining sensors, control units, and positioning mechanisms that can handle varying glass panel sizes without human intervention, thus improving both productivity and flexibility

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

2Productivity

If robotic loading systems are used, then productivity increases, but the risk of damaging glass panels increases

Engineering Contradiction:
Improveloading automation and speedVSAvoiddamage risk to glass panels
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

A sensor-based detection system acts as an intermediary between the control unit and the positioning mechanism, enabling precise, damage-free positioning by detecting panel edges and corners optically rather than through direct mechanical contact

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Direct mechanical manipulation by robots is replaced with a sensor-guided positioning system that uses optical fields and controlled mechanical movements to place glass panels safely, reducing contact forces that could cause damage

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

3Manufacturing precision

If glass panels are loaded one at a time, then precise positioning is achieved, but the conveyor frame utilization is suboptimal

Engineering Contradiction:
Improvepositioning accuracy of individual panelsVSAvoidconveyor frame utilization and throughput
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The control unit pre-calculates optimal positioning for multiple glass panels based on detected dimensions and conveyor frame capacity, arranging them in advance to maximize space utilization while maintaining precise positioning for each panel

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Sensors continuously detect the positions and dimensions of loaded panels, providing feedback to the control unit that adjusts subsequent positioning decisions to optimize conveyor frame utilization while maintaining precision

Inventive Principle:
Principle #23Feedback
