Solution Overview

Problem

The existing air duct assembly of indoor air conditioner units is inconvenient to disassemble and assemble, making maintenance, cleaning, and replacement complex and costly.

Innovation Solution

An indoor air conditioner unit design featuring a movably mounted air duct assembly with a mounting bracket that can be easily pulled out and reinserted through a downward opening in the housing, allowing for simplified maintenance and improved installation stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the air duct assembly is fixedly installed in the housing, then the installation stability is improved, but the ease of disassembly and assembly for cleaning deteriorates

Engineering Contradiction:
Improveinstallation stabilityVSAvoidease of disassembly and assembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting bracket is designed with movable connection structures including sliding slots and locking latches that allow the air duct assembly to be dynamically adjusted between fixed and movable states. The sliding slots guide the movement of inserting members while locking latches provide secure fixation when engaged, enabling easy removal when disengaged.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The air duct assembly is segmented from the housing through the use of a separate mounting bracket that can be independently removed. This segmentation allows the air duct assembly to be detached as a complete unit without damaging either the bracket or the housing, facilitating maintenance and cleaning operations.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the air duct assembly is made detachable for easy cleaning, then the ease of operation is improved, but the installation stability deteriorates

Engineering Contradiction:
Improveease of cleaningVSAvoidinstallation stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mounting bracket incorporates locking latches that can be engaged to secure the air duct assembly firmly in place during operation, or disengaged to allow easy removal for cleaning. This dynamic locking mechanism ensures stability when installed while maintaining ease of removal when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sliding slots are designed with curved trajectories that guide the inserting members along a predetermined path during insertion and removal. This curved guidance ensures proper alignment and seating of the air duct assembly, maintaining installation stability while enabling easy removal.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If complex disassembly procedures are required to access the air duct assembly, then the installation stability is improved, but the device complexity increases

Engineering Contradiction:
Improveinstallation stabilityVSAvoiddisassembly procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting bracket is designed as a self-contained assembly that can be removed as a single unit from the housing. The bracket integrates all necessary connection elements (sliding slots, locking latches, inserting members) into one component, eliminating the need to disassemble multiple separate parts to access the air duct assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting bracket combines multiple functions into a single component: it provides structural support for the air duct assembly, guides its insertion and removal through sliding slots, and secures it in place through locking latches. This merging of functions reduces the overall number of parts and simplifies the disassembly procedure.

Inventive Principle:
Principle #5Merging (Combining)
