Solution Overview

Problem

Conventional air conditioners face inefficiencies in installing the bottom housing assembly due to easy deviation from the preset position, requiring frequent adjustments, making the process inconvenient and time-consuming.

Innovation Solution

A guide structure comprising a guide slot and guide rail is introduced between the bottom housing assembly and the base, allowing for precise alignment and easy installation by sliding mechanisms, anti-falling protrusions, and thread connections to secure the assembly in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bottom housing assembly is detachably connected to the housing without a guide structure, then it is convenient to disassemble and wash the air conditioner, but the installation position easily deviates from preset position requiring frequent adjustments

Engineering Contradiction:
Improveconvenience of disassembly and washingVSAvoidinstallation position accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

A guide structure comprising a guide slot and guide rail is introduced as an intermediary element between the bottom housing assembly and the housing. The guide rail on the bottom housing assembly slides along the guide slot on the housing, ensuring the bottom housing assembly remains aligned with the preset position during installation while still allowing detachable connection for convenient disassembly and washing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the bottom housing assembly is detachably connected without guide structure, then it allows easy disassembly for maintenance, but installation efficiency is reduced due to frequent position adjustments

Engineering Contradiction:
Improveease of disassembly for maintenanceVSAvoidinstallation efficiency
Core Design Contradiction:
Ease of repairVSProductivity

Solution Approach 1:

The guide structure acts as a mediator that facilitates both easy disassembly for maintenance and efficient installation. The guide slot and guide rail enable quick alignment during installation, reducing the need for frequent adjustments, while the detachable connection maintained through this guide structure allows straightforward disassembly for maintenance purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional detachable connection is used, then the bottom housing can be removed for washing, but the installation position deviates requiring multiple adjustments

Engineering Contradiction:
Improvedetachability for washingVSAvoidtime for position adjustments
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The guide structure serves as an intermediary mechanism that preserves the detachability feature for washing while eliminating time loss from position adjustments. The guide rail sliding along the guide slot ensures automatic alignment during installation, so the bottom housing assembly connects quickly without requiring multiple position adjustments, thus maintaining adaptability while reducing time loss.

Inventive Principle:
Principle #24Intermediary (Mediator)
