Solution Overview

Problem

Conventional air conditioning indoor units experience significant changes in product contour when transitioning between operational and non-operational states, leading to mounting restrictions and aesthetic issues, particularly when installed close to ceilings.

Innovation Solution

The design incorporates a front panel system with a first panel positioned lower than a second panel, allowing the first panel to shift forward and upward to open blow-in and blow-out ports while maintaining an integrated appearance, with the second panel being hidden by the first panel in a front view, and utilizing a simplified mechanism that does not require shifting two panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the front panel shifts to open the blow-in port, then the air conditioning unit can operate, but the product contour changes significantly in a front view

Engineering Contradiction:
Improvepanel opening functionVSAvoidproduct contour
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The front panel is divided into two separate panels: a first panel and a second panel. The first panel is responsible for opening the blow-in port, while the second panel remains stationary to maintain the product contour. This segmentation allows the opening function to be achieved without changing the overall shape of the air conditioning unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The opening function is extracted from the entire front panel and assigned specifically to the first panel. The second panel is retained as a fixed decorative element that preserves the product's external appearance. This extraction allows the functional requirement to be met while maintaining aesthetic consistency.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the first panel shifts forward to open the blow-in port, then air flow is enabled, but the mounting restriction increases due to size change

Engineering Contradiction:
Improveair flow capabilityVSAvoidmounting position flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

By segmenting the front panel into movable and stationary parts, the invention enables air flow functionality while keeping the overall unit dimensions consistent. This allows the air conditioner to be mounted in various positions including locations close to ceilings, as the product contour does not change during operation.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a single panel shifts to open both blow-in and blow-out ports, then the mechanism is simplified, but the panel design becomes complex

Engineering Contradiction:
Improvemechanism structureVSAvoidpanel configuration
Core Design Contradiction:
Device complexityVSShape

Solution Approach 1:

The front panel is segmented into two independent panels with distinct functions. The first panel handles blow-in port opening while the second panel remains fixed. This segmentation simplifies the mechanism by eliminating the need for complex multi-panel coordination, as each panel has a dedicated, simple function.

Inventive Principle:
Principle #1Segmentation

AI summary

It is an object of the invention to provide an air conditioning indoor unit having suppressed change in size in a front view between before and after panel motion as well as having simplified and excellent appearance. An air conditioning indoor unit (1) includes a first panel (111) positioned in a lower side and configured to shift to open a front end of a front blow-in port (4B). The first panel (111) and the second panel (112) are positioned inside a product contour in a front view, or are exposed slightly even when being exposed from the product contour. This configuration has less mounting restriction and achieves excellent appearance.
