Pivotable Window Bracket for Screen Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window blind headrail brackets require removal and screw disengagement from the window frame to allow inward movement of windows or screens for cleaning, leading to screw hole wear over time.
Innovation Solution
A pivotable bracket design that secures the headrail to the window frame without needing to remove screws, allowing for the window or screen to be moved inwardly without disassembling the bracket, featuring a U-shaped profile with pivotable members and resilient locking mechanisms to facilitate easy removal and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional brackets are used to secure headrails to window frames, then secure attachment is achieved, but screw holes wear over time due to repeated removal and reattachment
Solution Approach 1:
The bracket is divided into two separate members: a first member that remains permanently attached to the window frame, and a second member that is removably attached to the headrail. This segmentation allows the window screen to be removed without detaching the bracket from the frame, eliminating repeated screw removal and preventing screw hole wear while maintaining secure attachment when needed.
2Ease of operation
If brackets are removed to allow inward movement of windows or screens for cleaning, then ease of operation is improved, but device complexity increases due to repeated assembly and disassembly
Solution Approach 1:
By separating the bracket into a permanent first member and a removable second member, the system simplifies the operation: users only need to detach the second member from the headrail, not the entire bracket from the frame. This reduces the complexity of repeated assembly and disassembly while improving ease of operation for window screen removal.
Solution Approach 2:
The second member is designed with dynamic attachment characteristics, allowing it to be easily connected and disconnected from the headrail using simple fastening mechanisms. This dynamic design enables quick removal and reattachment without complex tools or procedures, improving ease of operation while keeping the overall system relatively simple.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the removal of windows or screens without disassembling the bracket, reducing wear on screw holes and simplifying the cleaning process while maintaining secure attachment to the window frame.
Implementation Method 1
A resilient locking member extends between the pair of knuckles of the second member

AI summary
A window system includes a window frame, a window screen, blinds, and a bracket operable to secure the blinds to the window frame. The bracket is selectively securable to an interior surface of the window frame. With the bracket secured to the window frame, the bracket is operable to couple with a headrail of the blinds to thereby secure the blinds to the window frame. In some versions of the bracket, the bracket may be collapsible between an open position and a closed position to thereby allow for removal of the window screen from the window frame with the bracket secured to the window frame. In other versions, the bracket may have a sufficiently low profile to thereby allow for removal of the window screen from the window frame with the bracket secured to the window frame.
