Solution Overview

Problem

The existing design of air-conditioning indoor units restricts the shape design due to the pivot path of top panels, particularly when a remote-control communication unit is located at a lower position, limiting its placement outside the pivot path region.

Innovation Solution

The top panel is configured to detach downward from the back casing around a pivot axis, allowing the remote-control communication unit to be positioned outside the pivot path, thereby eliminating design restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the top panel is detached by opening upward around the upper back end portion, then the top panel can be easily removed for replacement, but the remote-control communication unit at a lower position must be disposed outside the pivot path region, restricting shape design

Solution Approach 1:

The patent inverts the traditional upward-opening detachment mechanism by implementing a downward-opening mechanism. The top panel is configured to pivot downward from the front end around a pivot axis at the upper back end portion, causing the panel to open in the opposite direction. This inversion allows the remote-control communication unit to be positioned in the lower portion of the top panel without interfering with the pivot path, thereby resolving the spatial conflict and enabling flexible shape design while maintaining ease of operation

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the spatial dimension of the pivot path by moving the pivot axis to the upper back end portion and configuring the panel to open downward. This dimensional reconfiguration creates a pivot path that extends downward and backward, effectively separating the pivot region from the lower front portion where the remote-control communication unit is located. This dimensional change eliminates the restriction on placing the communication unit in the lower portion while preserving the detachment function

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
