Solution Overview

Problem

The existing ceiling-embedded indoor air conditioner units require the removal of multiple components, including the fan, drain pan, and guide member, for maintenance, which complicates the process and can lead to inefficiencies and noise due to air accumulation.

Innovation Solution

The air conditioner design allows for the fan to be detached without removing the guide member, with a heat exchanger positioned radially to perform heat exchange and a guide member integrated with the drain pan to direct air efficiently, reducing noise and improving maintenance by preventing air accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the guide member and drain pan are constructed as separate removable components, then the air flow guidance function is improved, but the maintenance complexity increases as the fan must be removed after these components

Engineering Contradiction:
Improveair flow guidanceVSAvoidmaintenance procedure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide member is integrated with the drain pan to form a single unified component. This merging eliminates the need to separately remove the drain pan and guide member during fan maintenance, allowing the fan to be directly accessed and removed without disassembling these components individually, thus simplifying the maintenance procedure while maintaining the air flow guidance function.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of repair

If multiple components are made removable for maintenance access, then the maintainability is improved, but the number of parts increases and assembly complexity worsens

Engineering Contradiction:
Improvefan maintenance accessVSAvoidnumber of components
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

By combining the guide member and drain pan into one integrated component, the patent reduces the total number of separate parts in the system. This integration maintains easy access to the fan for maintenance purposes while avoiding the complexity of having multiple separate removable components, thus improving ease of repair without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If the fan is positioned close to the heat exchanger for compact design, then the device size is reduced, but air accumulation and noise increase

Engineering Contradiction:
Improveindoor unit sizeVSAvoidair accumulation and noise
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The integrated guide member-drain pan assembly is designed with a specific structure that segments and directs the air flow path between the fan and heat exchanger. The guide member portion creates defined flow channels that prevent air accumulation in unwanted areas, while the drain pan integrates beneath this structure. This segmentation allows compact positioning of components while maintaining proper air flow and reducing noise through controlled air movement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide member acts as an intermediary structure between the fan and heat exchanger, mediating the air flow in the narrow space between these components. It directs air flow smoothly from the fan toward the heat exchanger, preventing turbulence and air accumulation that would cause noise, while allowing the components to be positioned close together for compact design.

Inventive Principle:
Principle #24Intermediary (Mediator)
