Extendable Window Sash Creates Balcony Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window systems do not allow building occupants to safely and comfortably access or occupy space beyond the exterior facade, limiting the use of additional outdoor space in densely populated urban areas where building codes restrict the creation of balconies or permanent structures.
Innovation Solution
The development of window systems that extend beyond the building's facade, such as awning, casement, hopper, and extending embodiments, which provide enclosed and shielded spaces by rotating, swinging, or translating outward to create usable areas for occupants, incorporating mechanisms like pivot rods and collapsible materials for safe and comfortable outdoor access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional window systems are used, then the building facade remains simple and compact, but occupants cannot access or occupy space beyond the exterior facade
Solution Approach 1:
The window system incorporates movable components including a sash that can swing outward and extend beyond the facade, transforming the static window into a dynamic structure that creates usable exterior space when opened. The sash pivots on a pivot rod and can be positioned at various angles to form a balcony-like structure.
Solution Approach 2:
The window system extends from the two-dimensional plane of the facade into the third dimension by allowing the sash to project outward from the building. This creates a spatial volume beyond the facade that occupants can occupy, effectively adding exterior space without increasing the building's footprint.
2Area of stationary object
If window systems extend beyond the facade to create usable space, then occupants gain access to additional outdoor space, but the structural complexity and safety requirements increase
Solution Approach 1:
The window system performs multiple functions: it provides natural light and air ventilation when opened, creates usable exterior space for occupants, and can be integrated with building facade elements. The sash serves both as a window component and as a structural element forming the balcony-like extension.
Solution Approach 2:
The window system merges the window sash with balcony-like structural elements, combining functions that were traditionally separate. The sash, pivot rod, and supporting brackets work together as an integrated system that simultaneously provides window operation and exterior space creation.
3Reliability
If permanent balcony structures are created, then occupants gain stable exterior access, but building codes in densely populated areas restrict such structures
Solution Approach 1:
The system uses a movable sash that can be positioned and locked at various angles, providing stable exterior access when needed while allowing the window to return to its closed position. The pivot rod and bracket system enable reliable operation while maintaining the ability to adapt to different usage requirements.

AI summary
A window with multiple elements which are suitable for installation in a building exterior wall as part of designing and/or retrofitting building facades is disclosed. The building structure comprises one or more movable members movably attached to a frame member where the frame member is secured in a wall opening. The building structure may further comprise a sash member attached to the one or more movable members. The connection of these members may be such that an enclosure is created when the building structure is in an extended or open position.
