Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glass breakage during processing and filling is a significant issue in the packaging industry, leading to costly product losses and production inefficiencies, primarily due to flaws introduced in the glass surface during handling and ion exchange processing.
Innovation Solution
The magazine apparatus uses wire coil ware keepers with a spacer coil and base frame design to minimize contact-induced flaws, featuring a low thermal mass and surface area to enhance ion exchange performance and reduce mechanical stress on glassware, thereby preventing breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional holding apparatuses are used during ion exchange processing, then glassware can be held and processed, but mechanical stress and thermal impact cause glass breakage and surface flaws
Solution Approach 1:
The patent employs a wire coil structure that acts as a flexible retention body, replacing rigid holding apparatuses. The wire coil can deform elastically to accommodate glassware during ion exchange processing, reducing mechanical stress concentrations that would otherwise cause breakage or surface flaws. The flexibility allows the structure to adapt to thermal expansion without imposing excessive forces on the glassware.
Solution Approach 2:
The retention body is segmented into multiple wire coils rather than being a solid continuous structure. This segmentation reduces the thermal mass and surface area in contact with the glassware, minimizing thermal impact. The spaced wire coils allow for uniform heat distribution and reduce localized thermal stress on the glassware surface during ion exchange processing.
2Stability of the object's composition
If rigid holding structures are used, then structural stability is maintained, but contact between glassware and equipment introduces surface flaws leading to breakage
Solution Approach 1:
The wire coil structure provides a flexible yet stable holding mechanism. The coils maintain structural stability through their geometric configuration while their flexibility prevents rigid contact that would create surface flaws. The wire material and coil design allow for compliant contact with the glassware, eliminating stress concentration points that lead to breakage.
3Strength
If high thermal mass holding apparatuses are used, then structural integrity is maintained, but thermal impact on glassware increases causing breakage
Solution Approach 1:
The retention body is divided into multiple discrete wire coils with spacing between them. This segmentation dramatically reduces the total surface area and thermal mass of the holding apparatus compared to a solid structure. The reduced thermal mass minimizes heat transfer to the glassware during ion exchange processing, preventing thermal shock and associated breakage while maintaining sufficient structural integrity through the distributed coil configuration.
