Solution Overview

Problem

Window-mounted air conditioners suffer from noise and vibration transmission to indoor spaces, damage from hitting the window frame, water ingress, and unconditioned air leakage through gaps, which degrade user comfort and appearance.

Innovation Solution

An installation kit is designed to support the air conditioner, minimizing noise and vibration transmission by using a matching material and color with the case, sealing gaps with gaskets, and providing a secure fit to the window frame, thereby enhancing appearance and reducing production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the air conditioner is mounted directly between the window frame and window, then the installation is simple, but noise and vibration are transmitted to the indoor space

Engineering Contradiction:
ImproveInstallation simplicityVSAvoidNoise and vibration transmission
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a mounting bracket as an intermediary component between the air conditioner and the window frame. This bracket serves as a mediator that isolates the air conditioner from direct contact with the window frame, thereby reducing noise and vibration transmission while maintaining installation simplicity. The bracket acts as a buffer zone that absorbs harmful vibrations and prevents their direct transmission to the indoor space.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the air conditioner is mounted directly between the window frame and window, then the structure is simple, but the case may be damaged from continuous contact with the window frame

Engineering Contradiction:
ImproveStructure simplicityVSAvoidCase durability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The mounting bracket serves as a protective intermediary between the air conditioner case and the window frame. It prevents direct continuous contact that would cause damage to the case, while adding minimal structural complexity. The bracket absorbs mechanical stresses and prevents the case from being damaged by repeated contact with the rigid window frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the air conditioner is mounted directly between the window frame and window, then the installation is straightforward, but water and rain may flow into the room

Engineering Contradiction:
ImproveInstallation straightforwardnessVSAvoidWater ingress
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The mounting bracket creates an intermediary space between the air conditioner and the window frame that can be sealed with waterproof materials. This intermediate structure allows for effective water and rain sealing without complicating the installation process significantly. The bracket provides a surface for attaching waterproof membranes or sealants that direct water away from the indoor space.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If the air conditioner is mounted directly between the window frame and window, then the installation is simple, but unconditioned air and foreign matter may enter through gaps

Engineering Contradiction:
ImproveInstallation simplicityVSAvoidAir leakage and foreign matter accumulation
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The mounting bracket creates an intermediary sealing surface between the air conditioner case and the window frame. This intermediate structure allows for effective sealing using gaskets or foam tapes, preventing unconditioned air and foreign matter from entering through gaps. The bracket provides a stable surface for applying sealants that block air leakage while maintaining installation simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An installation kit includes: a front panel disposed to cover an indoor side of a space in which an air conditioner is disposed between a window frame and a window, the front panel having an opening through which the air conditioner is inserted; a first side frame coupled to the front panel, and disposed to face the window; and a second side frame coupled to the front panel, and disposed to face the window frame, thereby stably installing the air conditioner in the window.
