Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing settling plate arrangements for cooling hollow glass articles lack individualized cooling capacity adjustments, leading to mechanical instability and potential damage due to varying temperatures, as they apply a uniform cooling effect to all items, which is inadequate for items with different temperature and mechanical properties.
Innovation Solution
The settling plate arrangement features dynamic pressure chambers in each field, with individually controllable valves and sensors, allowing for field-specific cooling air flow adjustments based on item-specific data, ensuring optimal cooling performance and mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform cooling capacity is applied to all hollow glass articles on the settling plate, then the cooling system is simple to operate, but articles with varying temperatures experience mechanical instability and potential damage
Solution Approach 1:
The settling plate is divided into multiple fields (first field, second field, etc.), each equipped with its own dynamic pressure chamber and cooling air supply system. This segmentation allows independent control of cooling capacity for each field, enabling adaptation to different article temperatures and types while maintaining operational simplicity through standardized field modules.
Solution Approach 2:
Each field is equipped with a dynamic pressure chamber whose pressure can be individually adjusted via control valves. This dynamic pressure control enables continuous adjustment of cooling air flow rates to match the specific temperature and mechanical stability requirements of different hollow glass articles, preventing both overheating and excessive cooling that could cause thermal stress cracks.
2Adaptability or versatility
If cooling capacity is adjusted for each individual article type, then article-specific cooling requirements are met, but the device complexity increases with multiple pressure chambers and control systems
Solution Approach 1:
Each field on the settling plate is equipped with cooling components (dynamic pressure chamber, valve, sensors) tailored to the specific cooling requirements of articles placed in that field. This local quality approach allows high adaptability to different article types while maintaining moderate overall complexity through modular replication of standardized field units across the settling plate surface.
Solution Approach 2:
The system controls cooling capacity by dynamically adjusting the pressure parameter in each field's dynamic pressure chamber. This single parameter control method simplifies the complexity of managing multiple cooling variables, as pressure adjustment simultaneously affects cooling air flow rate, cooling intensity, and article stability, enabling versatile adaptation through one primary control mechanism per field.
3Productivity
If frequent adjustments are made to cooling capacity for changing item types, then optimal cooling is achieved, but production time is lost and hot cracks may develop
Solution Approach 1:
The system measures the temperature of each hollow glass article before it is placed on the settling plate using temperature sensors. Based on this preliminary temperature measurement, the control system pre-adjusts the cooling capacity settings for the appropriate field before the article begins cooling. This eliminates the need for frequent manual adjustments during the cooling process, maintaining continuous production flow while ensuring optimal cooling parameters are applied from the start.
Solution Approach 2:
Temperature sensors continuously monitor the temperature of articles in each field, and this feedback information is used by the control system to automatically adjust the pressure and cooling air flow rates in real-time. This closed-loop feedback control ensures optimal cooling capacity is maintained for different article types without requiring manual intervention, preventing thermal stress cracks while maintaining high productivity through automated adaptation.
