Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window frames have aesthetic drawbacks and unsatisfactory heat insulation, with large overall dimensions and low heat efficiency, necessitating a solution that enhances appearance and thermal performance while being simple, affordable, and easy to use.
Innovation Solution
A window frame design featuring a polygon-shaped double glazing with a mobile casing housed within the glazing, made of pultruded materials, and profiled elements that are completely or partially embedded in the wall, providing structural and thermal efficiency, and featuring sealing gaskets for improved insulation and a clean appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional fixed and mobile casings are used to frame the double glazing, then structural support is provided, but the overall dimensions become large and aesthetic quality deteriorates
Solution Approach 1:
The mobile casing is extracted from the traditional external framing position and placed inside the double glazing unit. Only profiled elements remain visible on the external surface, while the mobile casing performs its structural function hidden within the glass panes, resolving the conflict between structural support and aesthetic quality.
Solution Approach 2:
The mobile casing is nested within the double glazing unit, with profiled elements positioned between the glass panes. This nesting arrangement allows the structural components to be contained within the aesthetic envelope of the glass, eliminating the need for large external casings.
2Strength
If traditional fixed and mobile casings are used, then structural integrity is maintained, but heat insulation performance is insufficient
Solution Approach 1:
The frame structure uses composite construction with pultruded materials having thermal break properties. The profiled elements are designed as composite structures that maintain structural integrity while incorporating thermal insulation layers, reducing heat transfer through the frame.
Solution Approach 2:
The profiled elements are positioned in the third dimension within the double glazing unit rather than on the external surface. This spatial repositioning allows for thermal insulation layers to be integrated within the frame structure without increasing external dimensions, improving heat insulation while maintaining structural integrity.
3Reliability
If large dimensional fixed and mobile casings are used, then the double glazing is properly supported, but the window frame appears bulky and less appealing
Solution Approach 1:
The mobile casing is extracted from the external visible framework and repositioned inside the double glazing unit. This extraction removes the bulky appearance from the external view while the mobile casing continues to provide proper support function within the glass panes.
Solution Approach 2:
The support structure is moved from the two-dimensional external surface to the three-dimensional space within the double glazing unit. The profiled elements are positioned between the glass panes, providing structural support in the internal dimension while maintaining a clean external appearance.
4Ease of manufacture
If conventional frame designs are used, then manufacturing experience is available, but product differentiation from competition is limited
Solution Approach 1:
The frame is segmented into distinct functional components: fixed casing, profiled elements, mobile casing, and sealing gaskets. This segmentation allows each component to be manufactured independently using conventional processes while enabling novel assembly configurations that differentiate the product from traditional competitive offerings.
Solution Approach 2:
Instead of placing the mobile casing outside the glass as in conventional designs, this invention inverts the arrangement by positioning it inside the double glazing unit. This inverted configuration creates a distinctive product appearance and performance characteristics that differentiate it from competitive products while relying on conventional manufacturing processes for each component.
