Window Jack Scaffold Interior Installation Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window jacks are limited in their application as they cannot be installed from within a building and are unsuitable for use in recessed areas below windows, requiring external installation.
Innovation Solution
A window jack scaffold with internal vertical members and a platform that can be assembled and installed from inside a building, using brackets and support structures to extend through a window or door opening, allowing for interior mounting and providing access to the exterior with a safety rail assembly for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the window jack is installed from the exterior with the bracket resting against the exterior wall, then the window jack can be supported by the wall, but it cannot be used in recessed areas and requires external installation
Solution Approach 1:
The patent inverts the traditional installation approach by moving the bracket from the exterior wall to the interior wall. The bracket is now attached to the interior surface and extends through the window opening to support the platform from inside the building, enabling installation from the interior rather than exterior
Solution Approach 2:
The redesigned window jack system achieves multi-functionality by being adaptable to both flush and recessed window applications. The bracket can be installed on interior surfaces regardless of whether the window area is recessed or flush, and the platform can be positioned at various heights to accommodate different installation scenarios
2Adaptability or versatility
If the platform rests on the window sill, then the window jack is supported, but it cannot be used for window installation
Solution Approach 1:
The patent extracts the platform support function from the window sill and relocates it to the bracket system attached to the interior wall. The bracket extends through the window opening and directly supports the platform, eliminating the dependency on the window sill for structural support
Solution Approach 2:
The bracket serves as an intermediary element that transfers the load from the platform through the window opening to the interior wall. This intermediary structure enables the platform to be supported independently of the window sill, allowing window installation applications
3Reliability
If the window jack is installed from the exterior, then the bracket can be secured to the wall, but the installation process is more complex and time-consuming
Solution Approach 1:
The patent inverts the installation sequence by attaching the bracket to the interior wall surface first, then extending it through the window opening to support the platform. This reverses the traditional exterior-to-interior installation process, enabling faster and more accessible installation from the interior side

AI summary
A method and apparatus for providing access to the exterior of a building in proximity to an opening, such as a window or door opening, in a wall of the building. Access is provided by a platform that is supported by brackets from vertical members fastened to the interior of the building. The platform may be passed from the interior of a building to the exterior of the building through an opening in the building. The apparatus may be assembled in, and installed from, the interior of a building.
