Window AC Security Bracket Assembly to Prevent Unauthorized Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window air conditioners lack effective security measures to prevent the window from being opened, posing risks of unauthorized entry or accidental falls, especially when installed in homes with children.
Innovation Solution
An AC window security device comprising a sill plate bracket, U-brackets, and J-brackets, which are secured to the window sill and frame to prevent the window from being opened, using elongated strips and hooks to create a stable barrier around the air conditioner unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a window AC unit is installed in a partially open window, then cooling function is provided, but the window cannot be securely prevented from being opened
Solution Approach 1:
The security device is divided into separate functional components: sill plate brackets that attach to the window sill, vertical brackets that provide structural support, and cross bars that span across the top of the AC unit. This segmentation allows each component to perform its specific function while collectively providing secure window protection.
Solution Approach 2:
The sill plate brackets are installed and secured to the window sill before the AC unit is placed in the window. This preliminary action establishes a secure foundation that prevents the window from being opened, upon which the rest of the security device can be built.
2Reliability
If a security device is added to prevent window opening, then security is improved, but installation and maintenance become more difficult
Solution Approach 1:
The security device incorporates removable cross bars that can be easily detached and reattached, allowing for seasonal adjustments, maintenance access, or relocation. This dynamic design maintains security while providing operational flexibility.
Solution Approach 2:
The sill plate brackets serve multiple functions: they anchor the security device to the window sill, provide structural support for the vertical brackets, and create a secure base that prevents window opening. This multi-functionality reduces the number of separate components needed.
3Object-affected harmful factors
If the window is kept partially open for AC installation, then cooling is provided, but unauthorized entry or accidental falls become possible
Solution Approach 1:
The security device extends the barrier concept from a simple horizontal blockage to a three-dimensional structure with vertical brackets reaching from the sill to above the AC unit, and cross bars spanning across the top. This multi-dimensional approach provides comprehensive protection against both horizontal and vertical access attempts.
Solution Approach 2:
The security device acts as an intermediary structure between the window sill and the space above the AC unit, creating a physical barrier that prevents direct access through the window opening while allowing the AC unit to remain installed and functional.

AI summary
An AC window security device is provided, comprising: a sill plate bracket, a cross-bar, a pair of U-brackets, and a pair of J-brackets. The sill plate bracket is configured to be secured to a window sill under a window AC unit in an at least partially open window. The lower end of each U-bracket hooks into an opening in one end of the sill plate bracket and extend vertically along a side of the AC unit. The upper end of each J-bracket fits over an upper frame of the at least partially open window. The upper end of each U-bracket is removably secured to the lower end of a corresponding J-bracket. The cross-bar is configured to be positioned along a top surface of the AC unit and removably secured to both U-brackets, wherein the at least partially open window is prevented from being opened.
