Adjustable Window AC Bracket for Secure Gap-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window air conditioners are not securely mounted in window frames due to size mismatches, often requiring shims or permanent adjustments, which can lead to air gaps and reduced cooling efficiency, and existing solutions necessitate tools and structural damage.
Innovation Solution
A bracket with adjustable support legs and arms that can be slidably extended and locked in place without tools, allowing secure fitting of air conditioners of various sizes without damaging the building, using telescoping parts and a flexible end face for uneven surfaces, and securing mechanisms to prevent shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size bracket is used to mount the air conditioner, then the installation is simple, but it cannot adapt to air conditioners of various sizes and creates air gaps
Solution Approach 1:
The bracket incorporates adjustable arms with multiple positioning holes that allow the bracket width to be dynamically changed to match different air conditioner sizes. The support legs can also be adjusted in length and angled to fit various window configurations, transforming a static bracket into a dynamic, adaptable mounting system.
Solution Approach 2:
The bracket is divided into separate adjustable components including multiple arms, support legs, and positioning mechanisms. Each segment can be independently adjusted to achieve the proper fit, allowing the overall bracket structure to adapt to various air conditioner dimensions without requiring a completely different bracket for each size.
2Manufacturing precision
If shims or adjustment devices are used to fit the air conditioner, then the size mismatch is compensated, but the installation becomes complex and air gaps may still form
Solution Approach 1:
Instead of using static shims, the bracket employs adjustable arms with multiple positioning holes that allow precise positioning of the air conditioner within the bracket. This dynamic adjustment system enables the bracket to conform precisely to the air conditioner dimensions while maintaining structural integrity and eliminating air gaps.
Solution Approach 2:
The bracket allows changing of key geometric parameters including arm length, arm angle, and support leg position through the adjustable holes and positioning mechanisms. By varying these parameters, the bracket can achieve precise fit for different air conditioner sizes and shapes without requiring complex shimming procedures.
3Reliability
If screws, bolts, or permanent affixing methods are used to secure the bracket, then the mounting is secure, but the building structure is damaged and tools are required
Solution Approach 1:
The bracket is designed to be self-supporting through its adjustable support legs that rest against the window sill and side jambs. The friction and geometric interlocking provided by the adjustable positioning holes and support structures enable the bracket to hold the air conditioner securely without requiring permanent affixing to the building structure, thus avoiding damage and eliminating the need for tools during installation.
Solution Approach 2:
The adjustable arms and support legs act as intermediaries between the air conditioner and the window frame. These components transfer and distribute the load of the air conditioner to the window structure through multiple contact points created by the adjustable positioning system, providing secure mounting without the need for direct fastening that would damage the building.
4Adaptability or versatility
If the bracket is designed to fit all window sizes, then the versatility is improved, but the device complexity and adjustment mechanisms increase
Solution Approach 1:
The bracket uses adjustable arms and support legs with multiple positioning holes that can be configured to match various window dimensions. This dynamic adjustability allows a single bracket design to serve multiple window sizes while maintaining ease of installation through a standardized adjustment procedure rather than requiring different brackets for each window size.
Solution Approach 2:
The bracket is designed as a universal mounting system where the same basic structure with adjustable components can accommodate different air conditioner sizes and various window configurations. The adjustable arms, support legs, and positioning mechanisms provide multi-functionality, allowing the single bracket design to perform the mounting function across a range of applications without increasing operational complexity.

AI summary
A bracket for mounting an air conditioning unit in a window has a base plate having a front edge and a rear edge and a pair of support legs connected to the base plate and extending from the rear edge, each support leg having an end face that faces in a same direction as the front edge and a support trough connected to the front edge. There are adjustable arms connected to the support trough. These arms are slidable in opposite directions to increase the width of the bracket and fit it exactly to the width of the window frame. When the bracket is positioned in a window frame of a structure, the support trough fits within the window frame and the end faces of the each support leg rest against an exterior of the structure.
