Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fastening windows or doors in wall openings require significant skill and effort, are costly due to complex assembly processes, and often involve large openings or precise tolerances, making them difficult and expensive to install.
Innovation Solution
A device with a wall bracket and component bracket that feature a slot-shaped connection opening, allowing for a plug-like connection with a threaded bolt and locking elements, enabling easy assembly and adjustment without requiring extensive installation effort, and allowing for pre-assembly during production to simplify installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screw connections and adjustment steps are used to fasten the window, then the fastening reliability is improved, but the assembly complexity and installation time increase significantly
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated bracket system. The bracket incorporates both the mounting function to the wall and the window attachment function in one component, eliminating the need for separate wall brackets, component brackets, and multiple adjustment operations. This merging reduces assembly complexity while maintaining fastening reliability through the unified structural design.
Solution Approach 2:
The bracket is pre-assembled with the window frame during manufacturing, with threaded bolts and fixing elements already in place. This preliminary action eliminates the need for on-site assembly adjustments and reduces installation time. The pre-configuration ensures proper alignment and tolerance compensation without requiring complex adjustment procedures during installation.
2Ease of operation
If a sleeve is inserted into the window frame to accommodate the threaded bolt, then the assembly process is simplified, but a large opening must be prefabricated in the window frame increasing production effort and cost
Solution Approach 1:
The patent extracts the sleeve component from the window frame assembly. Instead of inserting a sleeve into a large opening in the window frame, the threaded bolt is directly attached to the bracket which is then mounted to the wall. This eliminates the need for prefabricating large openings in the window frame, reducing production effort and cost while maintaining assembly simplicity.
3Ease of operation
If the connection opening is designed as a slot open in the direction of the window plane, then the threaded bolt can be inserted, but the window must first be inserted with lateral offset and then adjusted within the building opening making assembly more difficult
Solution Approach 1:
The patent inverts the traditional assembly sequence. Instead of inserting the window first and then attaching the bracket, the bracket with the slot-shaped connection opening is pre-mounted to the wall. The window is then directly attached to the pre-positioned bracket, eliminating the need for lateral offset insertion and subsequent adjustment within the building opening. This inversion simplifies the assembly procedure while maintaining ease of bolt insertion.
