Ceiling-Embedded Air Outlet Layout for Wide-Range Room Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-embedded air conditioners have difficulty uniformly air-conditioning a room due to fixed air blowing openings, which restrict airflow direction and range.
Innovation Solution
A ceiling-embedded air conditioner design featuring a decorative panel with a raised elliptical portion containing a fixed air blowing portion and rotatable truncated cone-shaped movable air blowing portions, allowing conditioned air to be blown out in multiple directions for wider coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed air blowing opening is used, then the device structure is simple, but the air blowing range is limited and uniform air-conditioning of the room is difficult
Solution Approach 1:
The patent applies the dynamics principle by making the air blowing openings movable rather than fixed. The decorative panel includes multiple air blowing openings that can change their opening directions independently, allowing the air conditioner to adapt to different air conditioning needs and blow air in multiple directions to achieve uniform room conditioning.
Solution Approach 2:
The patent segments the air blowing function by providing multiple separate air blowing openings (first air blowing opening, second air blowing opening, third air blowing opening) instead of a single fixed opening. Each opening can be independently controlled to change its direction, enabling comprehensive coverage of the room space.
2Adaptability or versatility
If airflow direction vanes are moved in a fixed air blowing opening, then airflow direction can be adjusted, but the air blowing range remains limited to one direction
Solution Approach 1:
Instead of using movable vanes within a fixed opening, the patent employs multiple openings that can dynamically change their opening directions. This approach provides a broader air blowing range while maintaining ease of operation through automated control of the opening directions.
Solution Approach 2:
The patent transitions from adjusting airflow in a single fixed direction to providing airflow control in multiple spatial dimensions. By having openings at different locations (front, side surfaces) that can independently change directions, the system achieves three-dimensional air distribution coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables uniform air-conditioning of a room by allowing conditioned air to be blown horizontally over a wide range, improving airflow distribution and maintaining an aesthetically pleasing appearance.
Implementation Method 1
The air sucked from the suction opening can exchange heat with the refrigerant in the heat exchanger
Implementation Method 2
an air blower and a heat exchanger... an air blowing opening provided on the decorative panel... conditioned air is blown out from the air blowing opening

AI summary
An air conditioning indoor unit includes a central fixed air blowing portion in a raised portion having an elliptical shape in a plan view in which a part of a decorative panel is raised toward an air conditioning room. Movable air blowing portions are included on both left and right sides of the indoor unit. Each movable air blowing portion includes a truncated cone-shaped rotation unit rotatable about an axis orthogonal to the decorative panel or the ceiling of the room. Semi-circular portions are formed at both ends of the raised portion by a part of the rotation units, and an air blowing opening is formed on each side surface of the fixed air blowing portion and the movable air blowing portion, so that the conditioned air is blown out from the air blowing opening over a wide range as the movable air blowing portion rotates.
