Solution Overview

Problem

Traditional window air conditioning units require complex and risky user-installed setups, while ductless systems necessitate professional installation, which is expensive and time-consuming, and both lack user-friendly installation processes.

Innovation Solution

A method for installing a split-architecture air conditioning unit through a standard window opening using a bracket assembly that secures both indoor and outdoor units, allowing for safe, tool-free installation without modifying the building envelope, featuring a weight offset mechanism and guided pivot arm for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional window air conditioning units are installed by users, then installation cost is reduced, but installation safety deteriorates due to precarious balancing and risk of units falling

Engineering Contradiction:
Improveinstallation costVSAvoidinstallation safety
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces a bracket assembly as an intermediary device between the window sill and the air conditioning unit. This bracket provides a secure mounting structure that eliminates the need for users to precariously balance the unit, thereby maintaining low installation cost while significantly improving installation safety and reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The bracket assembly is pre-installed on the window sill before the air conditioning unit is placed. This preliminary action creates a secure foundation that guides and supports the unit during installation, preventing falls and accidents before they can occur

Inventive Principle:
Principle #10Preliminary action

2Use of energy by moving object

If ductless mini-split systems are installed, then operational efficiency is improved, but installation complexity increases requiring professional technicians

Engineering Contradiction:
Improveoperational efficiencyVSAvoidinstallation complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent divides the air conditioning system into separate indoor and outdoor units connected through a window opening. This segmentation allows each unit to be installed independently using simple bracket assemblies, eliminating the need for complex professional installation while maintaining the operational efficiency benefits of ductless systems

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket assembly is designed as a universal mounting device that can accommodate various air conditioning unit types and sizes. This multi-functional bracket simplifies installation across different scenarios, reducing complexity while preserving the efficiency advantages of modern AC systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-generated harmful factors

If ductless mini-split systems are installed, then operational quietness is improved, but installation time increases due to professional installation requirements

Engineering Contradiction:
Improvenoise levelVSAvoidinstallation time
Core Design Contradiction:
Object-generated harmful factorsVSLoss of time

Solution Approach 1:

The patent enables homeowners to perform the installation themselves using the simple bracket assembly system. This self-service approach eliminates the need to hire professional technicians, thereby reducing installation time and cost while maintaining the quiet operational characteristics of ductless mini-split systems

Inventive Principle:
Principle #25Self-service

4Stability of the object's composition

If traditional window units are secured with screws and brackets, then mounting stability is improved, but installation difficulty increases requiring multiple components

Engineering Contradiction:
Improvemounting stabilityVSAvoidinstallation difficulty
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent combines the mounting bracket, support structure, and securing mechanisms into a single integrated bracket assembly. This merging of components maintains mounting stability while simplifying the installation process, as users only need to install the pre-assembled bracket rather than coordinating multiple separate parts

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method of installing an air conditioning unit in an opening. The method includes securing a bracket to a sill of the opening between a first and second environment where the bracket has a pivot arm disposed and extending within the first environment. The method also includes positioning a first unit of the air conditioning unit on top of the bracket; moving the first unit on top of the bracket onto the pivot arm; and rotating the pivot arm and first unit downward so that the first unit is disposed in the first environment and extending downward below the sill of the opening.
