Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The flat glass industry faces challenges with wear and high energy consumption due to the frequent rearrangement and movement of glass sheets and insulating glass panes, particularly during cutting, grinding, and tempering processes, where high speeds and accelerations lead to increased friction, wear, and energy use, despite the need for efficient logistics to maintain productivity.
Innovation Solution
The implementation of a system utilizing fuzzy logic in combination with predictive analysis and sensor data to optimize the kinematic parameters of shuttles and storage modules, allowing for adaptive speed and acceleration adjustments to reduce wear and energy consumption, while ensuring efficient movement and rearrangement of glass elements between workstations.

Engineering Contradiction Analysis
1Productivity
If high speeds and accelerations are used to move glass sheets and insulating glass panes between workstations, then productivity is improved, but wear on mechanical components and energy consumption increase
Solution Approach 1:
The system dynamically adjusts the speed and acceleration parameters of shuttles based on real-time conditions. The control unit receives data from sensors monitoring the state of glass elements and workstations, then optimizes kinematic parameters to balance productivity with energy efficiency and wear reduction, rather than operating at constant high speeds
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor the position, state, and conditions of glass elements and workstations. This data is fed to the control unit which adjusts shuttle speeds and accelerations in real-time, creating a closed-loop control system that optimizes energy consumption while maintaining productivity
2Productivity
If high speeds and accelerations are used to move glass sheets and insulating glass panes between workstations, then productivity is improved, but wear on mechanical components increases
Solution Approach 1:
The system dynamically adjusts the speed and acceleration parameters of shuttles based on real-time conditions. The control unit receives data from sensors monitoring the state of glass elements and workstations, then optimizes kinematic parameters to balance productivity with wear reduction, rather than operating at constant high speeds
Solution Approach 2:
The system prepares and optimizes movement parameters in advance to prevent excessive wear. By predicting required movements and pre-calculating optimal speed profiles, the system avoids sudden accelerations and decelerations that would increase mechanical stress and wear on components
3Adaptability or versatility
If manual rearrangement using racks is used, then flexibility in handling different glass formats is improved, but labor intensity and time consumption increase
Solution Approach 1:
The automated system performs rearrangement operations autonomously without manual intervention. The shuttles automatically transport glass elements between workstations and storage zones, and the control unit autonomously manages the logistics coordination, eliminating the need for manual rack-based rearrangement while maintaining flexibility in handling various formats
Solution Approach 2:
The system replaces manual mechanical rack-based rearrangement with an automated shuttle-based transport system. The mechanical system uses motorized shuttles moving along rails to transport glass elements, substituting human labor with automated mechanical systems that are both faster and equally flexible in handling different formats
