Casement Window with Wide Spacer and Inclined Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window arrangements with closely spaced glass panes lack effective sound and heat insulation due to limited space between panes, restricting device placement and insulation efficiency.
Innovation Solution
A window design featuring a sash frame with two glass panes and a wider spacer between them, incorporating a casement element with inclined and potentially curved surfaces for enhanced light control, along with internal reinforcements and a desiccant, and adjustable cartridges for varying gases to improve insulation and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the distance between glass panes is increased, then sound and heat insulation is improved, but the space available for device placement increases complexity
Solution Approach 1:
The spacer bar is designed to perform multiple functions simultaneously: it maintains the increased distance between panes for insulation, provides structural reinforcement, incorporates a desiccant for moisture control, and includes integrated sealing elements. This multi-functionality resolves the contradiction by consolidating what would otherwise be separate devices into a single integrated component, improving insulation while managing complexity through functional integration.
2Adaptability or versatility
If the distance between glass panes is increased, then device placement options are improved, but manufacturing complexity increases
Solution Approach 1:
The spacer bar is pre-manufactured with all necessary components integrated before assembly, including the desiccant chamber, sealing elements, and reinforcement structures. This preliminary preparation of the spacer bar with built-in functionality allows for easier final assembly while maintaining the benefits of increased pane distance, thus resolving the contradiction between versatility and manufacturing ease.
3Reliability
If a desiccant is inserted into the wing element, then moisture removal is improved, but the wing element structure becomes more complex
Solution Approach 1:
The desiccant function is merged with the spacer bar structure by integrating a desiccant chamber or desiccant material directly into the spacer bar. This combines the moisture removal function with the existing structural component, improving reliability for moisture control while avoiding the need for a separate desiccant housing or additional structural elements that would increase complexity.

AI summary
The casement window has a gap (ZR) of more than 16.0 mm between the inner and outer panes and the outsides of the panes (3,4) and the casement element (1) are flush with one another. An adhesive layer (6,7) is placed between the outside of the casement element and the inside of the outer pane and is defined and covered by circumferential edge projections (1b, 1c) on the casement element. Heat insulating material is provided in the interspace between the panes and/or in the casement element and in the frame element (2). The surface (1a) of the casement in the interspace runs inclined or curved to the outside so that the light is deflected inside and/or outside of the interspace. An interchangeable gas-filled cartridge is connected to the interspace through a duct so that gas is automatically supplied and controlled in dependence on the gas pressure in the interspace.
