Nested Tempering Frame for Glass Pane Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tempering frames for thermal tempering of glass panes have a tall overall structure that limits the distance between blow boxes and the glass pane, resulting in reduced tempering efficiency and limited adjustability of the support frame to the pane curvature.
Innovation Solution
A tempering frame design where the support frame is arranged completely within the carrier frame, connected via connection elements that allow for precise adjustment of the support frame's shape, with recesses on the rear edge to enhance flexibility and air flow resistance reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the carrier frame and support frame are arranged one above another in conventional tempering frames, then the structure is simple and stable, but the overall height increases which limits the proximity of blow boxes to the glass pane, reducing tempering efficiency
Solution Approach 1:
The support frame is arranged completely within the carrier frame in plan view, with the carrier frame's outer perimeter enclosing the support frame's inner perimeter. This nesting arrangement allows the blow boxes to approach the glass pane much closer, eliminating the need for the tall overall structure of conventional frames while maintaining structural stability and enabling higher tempering efficiency.
2Productivity
If the carrier frame and support frame are locally offset to reduce overall height, then tempering efficiency improves, but the adjustability of the support frame to pane curvature decreases
Solution Approach 1:
The connection between the carrier frame and support frame is segmented into multiple discrete connection elements distributed along the perimeter. Each connection element can be independently adjusted, allowing the support frame to be precisely adapted to the specific curvature of different glass panes while maintaining the compact nested arrangement that enables high tempering efficiency.
3Adaptability or versatility
If the support frame is made more flexible to improve adjustability to pane curvature, then adaptability improves, but the structural stability and resistance to air flow decrease
Solution Approach 1:
The support frame exhibits local quality variations through its connection element design: the regions at the connection elements provide structural stability and rigidity to resist air flow, while the regions between connection elements maintain flexibility for adjustment to pane curvature. This localized differentiation of properties allows the frame to simultaneously achieve adaptability and structural integrity.
