Solution Overview

Problem

Existing security solutions fail to effectively secure window-mounted air conditioners while allowing for adjustable installation and preventing tampering or unauthorized entry.

Innovation Solution

A cage with a rectangular parallelepiped shape, comprising two slidably coupled sections, is positioned around the air conditioner, with adjustable width and open sides, and equipped with fasteners that engage the window's vertical edges to prevent tampering or entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size security cage is used, then the security structure is simple, but it cannot adapt to different air conditioner sizes and window dimensions

Engineering Contradiction:
Improveadaptability to different air conditioner sizesVSAvoidcage structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cage is divided into a first section and a second section that can slide relative to each other. This segmentation allows the cage to be adjusted to different sizes while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cage incorporates slidable sections with fasteners that can be moved and locked at different positions. This dynamic adjustment mechanism enables the cage to adapt to various air conditioner dimensions without requiring multiple different cage sizes, balancing adaptability with structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If security bars are used to secure the air conditioner, then the air conditioner is restrained, but the security bars can be easily removed by applying force

Engineering Contradiction:
Improvesecurity against tamperingVSAvoiddifficulty of removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The security system uses multiple fasteners distributed at different locations (front, rear, and sides) rather than a single bar. This segmentation creates multiple independent security points, making the overall system more reliable and harder to compromise while maintaining reasonable ease of operation through systematic installation and removal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fasteners are designed to be installed in a specific sequence and engage with the window frame in advance before the air conditioner is fully secured. This preliminary action ensures that the security structure is already in place and properly engaged, making removal more difficult while maintaining ease of proper installation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the cage is made completely enclosed, then security is maximized, but access for maintenance and installation becomes difficult

Engineering Contradiction:
Improvesecurity protectionVSAvoidaccessibility for maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cage is designed with an open side rather than being completely enclosed, creating a segmented security structure. This allows maintenance personnel to access the air conditioner easily while still providing security protection through the remaining enclosed sections and multiple fastening points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cage configuration allows the open side to be positioned strategically during installation and maintenance, then secured in a protected position during normal operation. This dynamic positioning enables the cage to provide maximum security when needed while allowing easy access when required.

Inventive Principle:
Principle #15Dynamics

AI summary

A window security assembly includes a cage structured to have a rectangular parallelepiped shape. The cage is further structured to have first section slidably coupled to a second section so the cage has an adjustable width. The cage is further structured to have an open side. The cage is positioned in a window such that the open side receives an air conditioner mounted in the window to surround the air conditioner. Each of a plurality of fasteners extends through the cage and engages the window such that the cage prevents an individual from tampering with the air conditioner or entering through the window.
