Window AC Support Rod Assembly for Tool-Free Secure Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window Unit Air Conditioners (WUACs) are difficult to install due to their weight and size, often requiring multiple individuals, technical skills, and tools, and pose safety risks during installation, as they can fall from windows during the process.
Innovation Solution
A one-step installation method using a tension force-based support apparatus that is adjustable and tool-free, allowing the WUAC to be securely fitted into a window without external tools, utilizing U-shaped and vertical rods that engage with the window frame and the unit's spine to distribute weight and prevent falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional installation methods are used with tools and external mounts, then the WUAC can be securely installed, but the installation process becomes complex and requires technical skills and drilling
Solution Approach 1:
The invention extracts and eliminates the need for external mounting brackets and drilling operations by integrating the support function directly into the window sash mechanism. The support rod is attached to the movable sash itself, removing the complexity of separate mounting components and steps while maintaining secure installation.
Solution Approach 2:
The window sash is given multiple functions: it serves both as the window opening/closing mechanism and as the support structure for the air conditioner. The support rod utilizes the sash's movement and positioning capabilities to provide automatic support, eliminating the need for dedicated mounting hardware.
2Ease of operation
If the WUAC is supported by the window sill alone, then the installation is simple, but the sill may not support the gravitational weight and the unit may fall or shift
Solution Approach 1:
The support rod is pre-positioned to engage with the window sash before the air conditioner is fully installed. This preliminary action ensures that the support mechanism is in place and ready to bear the weight, preventing the unit from falling or shifting during installation and operation.
Solution Approach 2:
The support rod acts as an intermediary element between the window sash and the air conditioner. It transfers the load from the heavy AC unit to the movable sash, which can dynamically adjust to support the weight, thereby ensuring reliable support without requiring the static window sill to bear the full load.
3Shape
If the WUAC extends beyond the window sill, then the unit can be properly positioned, but the external tilt causes instability and requires external mounts
Solution Approach 1:
The support system is made dynamic by attaching the support rod to the movable window sash. As the sash moves up and down, it dynamically adjusts the support position and angle, automatically compensating for the overhang and maintaining stability without requiring fixed external mounts.

AI summary
An adjustable assembly for installing and supporting a window unit air conditioner (WUAC) allowing a one-step easy installation and removal. The apparatus has two U-shaped horizontal member and one U-shaped vertical member that utilize the window frame and the weight of the WUAC, to install and keep the WUAC in place. The assembly fits behind and unto the spine of the WUAC as well as across the width of the WUAC. When lifted in place, the assembly fits against the window frame using gravity to securely keep the WUAC in place. The assembly may be used alone or in combination with the horizontal support member and/or the vertical member depending on the weight of the WUAC. The second U-shaped member is placed around both sides and the rear of the installed WUAC with the flange supported against the inner window frame. Using tension force, this provides support for the extruding WUAC. The vertical U-shaped member extends from the sides of the horizontal member and traverses the bottom of the WUAC to give support.
