Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass mold cooling systems in section machines often rely on uncontrolled or overly complex methods, leading to irregularities in cooling output across production sections, which can result in suboptimal glass body production quality and increased costs.
Innovation Solution
A method for controlling the cooling of multiple glass molds using shared absolute cooling medium parameters, where a primary actuating device sets a cooling capability variable, and a secondary actuating device adjusts the cooling pressure to maintain desired cooling output, while filtering out external disturbances to ensure consistent cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a cooling medium stream is shared by all production sections and subjected to closed-loop or open-loop control, then the control system can be simplified, but irregularities in cooling output occur across different production sections
Solution Approach 1:
The patent divides the cooling control into two levels: a primary actuating device that sets the overall cooling capability variable for the shared cooling medium stream, and secondary actuating devices at each production section that independently adjust local cooling parameters. This segmentation allows the system to maintain simplicity while ensuring consistent cooling output across all sections by addressing local variations without requiring complex centralized control for each section.
2Reliability
If individual cooling control is implemented for each production section, then cooling output consistency is improved, but device complexity and costs increase
Solution Approach 1:
The patent merges the control functions by having secondary actuating devices at each production section that receive and respond to the primary cooling capability variable setting. This allows individual section control to be achieved while maintaining a unified control approach that doesn't require fully independent complex control systems for each section, thereby reducing overall device complexity while ensuring cooling consistency.
3Ease of operation
If cooling control is based on average measured variables for all production sections, then control effort is reduced, but individual section conditions are not adequately addressed
Solution Approach 1:
The patent implements local quality control by enabling each production section to have its own secondary actuating device that can adjust cooling parameters according to specific local conditions while still operating within the framework of the primary cooling capability variable. This ensures that individual section conditions are adequately addressed to maintain glass body production quality without requiring excessive control effort, as the system leverages the primary setting to guide local adjustments.
