Solution Overview

Problem

Existing air conditioner indoor units are difficult to move and carry due to lack of application points on the sides, occupy unnecessary space, and have non-demountable side and top walls, making them hard to clean and update.

Innovation Solution

The air conditioner indoor unit features demountable side and top walls with convex parts that allow for easier handling and space utilization, and includes connecting plates for easy disassembly and cleaning, with reinforced ribs for enhanced strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the side walls are fixed and non-demountable, then the structural strength is maintained, but the cleaning and maintenance become difficult

Engineering Contradiction:
Improvecleaning easeVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The side walls are divided into demountable sections connected by connecting plates, allowing the walls to be separated for cleaning while maintaining structural integrity when assembled. The connecting plates with positioning holes and fastening mechanisms enable easy assembly and disassembly without compromising overall strength.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the side walls are made demountable for easy cleaning, then the maintenance becomes convenient, but the structural strength may be compromised

Engineering Contradiction:
Improvemaintenance easeVSAvoidstructural strength
Core Design Contradiction:
Ease of repairVSStrength

Solution Approach 1:

The connecting plates are pre-equipped with positioning holes and fastening structures that guide the assembly process. The side walls are designed with corresponding positioning features that align with these holes, ensuring proper positioning and strong connection before final fastening, thus maintaining structural strength while enabling easy disassembly for maintenance.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If convex parts are added to the side walls for better handling, then the hand-holding effect is improved, but the device complexity increases

Engineering Contradiction:
Improvehand-holding effectVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The convex parts are integrated directly into the side wall structures rather than being separate components. The first and second convex parts are formed as extensions of the side walls themselves, providing improved hand-holding effects without requiring additional separate parts or complex assembly mechanisms.

Inventive Principle:
Principle #5Merging (Combining)
