Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional window devices have a significant 'seen mass' of joinery, which affects aesthetic homogeneity and technical performance, and there is a need for a solution that minimizes this mass while maintaining good insulation and sealing properties.
Innovation Solution
A window device with zero 'seen mass' from the outside and inside, utilizing triple glazing with staggered edges for sealing, and profiles with insulating foam and seals to ensure thermal and acoustic insulation, applicable to various types of openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional joinery with frames is used, then structural strength and sealing are ensured, but the visible carpentry mass increases significantly affecting aesthetics
Solution Approach 1:
The invention extracts and removes the traditional frame structure from the visible exterior and interior surfaces. By eliminating the frame from the aesthetic view while maintaining its structural function through the staggered glass edge configuration, the solution reduces visible carpentry mass without compromising structural integrity.
Solution Approach 2:
The invention shifts the structural support function from a two-dimensional frame to a three-dimensional configuration using staggered glass edges at different depths. The glass panes are positioned at different distances from the exterior, creating a layered structure that provides structural strength without visible frames.
2Shape
If frame width is reduced to minimize visible mass, then aesthetic homogeneity improves, but thermal insulation performance deteriorates
Solution Approach 1:
The invention introduces an intermediary thermal insulation layer between the interior and exterior environments. This insulation layer is positioned within the staggered glass configuration, providing thermal protection while maintaining the aesthetic homogeneity of the glass surface from both interior and exterior views.
Solution Approach 2:
The invention creates a nested structure where multiple glass panes are positioned at different depths, with insulation layers nested between them. This layered configuration provides thermal insulation functionality while maintaining a sleek, frameless appearance from both interior and exterior perspectives.
3Shape
If frame width is reduced to minimize visible mass, then aesthetic homogeneity improves, but sealing performance deteriorates
Solution Approach 1:
The invention segments the sealing function across multiple interfaces between the staggered glass panes and the building structure. By distributing sealing requirements across several contact points and layers rather than relying on a single wide frame, the solution maintains air and water tightness while minimizing visible carpentry mass.
