Multi-Layered Glass Fitting With Airtight Gap-Sealing Sashes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-layered glass fittings face issues such as gaps allowing communication between interior and exterior, inability to open FIX panels, need for a cover member to close groove portions, and large dimensions in vertical direction due to perpendicular drive shafts, which affect watertightness, viewability, and compactness.
Innovation Solution
A fitting with a frame assembly and two sashes that can move in different directions, including airtight members and a drive unit, allowing the sashes to overlap and close gaps, ensuring viewability and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-layered glasses are aligned to form a fitting, then the fitting structure is formed, but gaps may be formed between adjacent glasses allowing communication between interior and exterior
Solution Approach 1:
Aitight members are introduced as intermediary sealing elements between adjacent multi-layered glasses and between sashes and frame assembly. These airtight members prevent gap formation and ensure watertightness and airtightness while allowing the glass panels to maintain their aligned structure.
2Ease of manufacture
If FIX panels are used in the ribbon window, then viewability is improved, but the panels cannot be opened
Solution Approach 1:
The patent transforms the static FIX panels into dynamic movable sashes that can slide within the frame assembly. The sashes are configured to be movable in the front-face direction, allowing them to open and close while maintaining the ribbon window aesthetic and viewability characteristics.
3Ease of operation
If a sash is moved within the frame assembly in the interior-exterior direction, then opening and closing is enabled, but a groove portion is formed in the frame assembly that needs to be closed
Solution Approach 1:
Aitight members are positioned in groove portions of the frame assembly to seal the spaces created when sashes move in the interior-exterior direction. This allows the sashes to be movable while the airtight members prevent formation of harmful gaps and maintain the sealing function.
4Ease of operation
If the drive shaft is driven in the vertical direction perpendicular to the longitudinal direction of the lower frame component, then the raising-lowering device functions, but the lower frame component tends to have a large dimension in the vertical direction
Solution Approach 1:
The patent reorients the drive shaft from a vertical arrangement to a horizontal arrangement that extends in the front-back direction. This dimensional change allows the raising-lowering function to be achieved while reducing the vertical dimension of the lower frame component, creating a more compact structure.
