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 portion containing a fixed air blowing portion and rotatable movable air blowing portions on both sides, allowing conditioned air to be blown out over a wide area along the panel surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed air blowing opening is used in the decorative panel, then the structure is simple and easy to manufacture, but the air blowing range is limited and the room cannot be uniformly air-conditioned
Solution Approach 1:
The air blowing function is segmented into a fixed air blowing portion and multiple movable air blowing portions. Each movable air blowing portion can independently rotate to change the air blowing direction, allowing the system to cover a wider area while maintaining a relatively simple overall structure.
Solution Approach 2:
The movable air blowing portions are designed to rotate about an axis orthogonal to the panel surface, transforming the static air blowing opening into a dynamic system that can adjust its blowing direction to cover different areas of the room, thereby improving adaptability without significantly complicating the structure.
2Adaptability or versatility
If movable air blowing portions are added to expand air blowing range, then the air conditioning coverage is improved, but the device complexity increases
Solution Approach 1:
The system divides the air blowing function into separate fixed and movable portions. The movable portions are positioned on both sides of the fixed portion and can rotate independently, allowing expanded coverage while keeping each component relatively simple and modular.
Solution Approach 2:
The movable air blowing portions serve multiple functions: they can rotate to different angles to cover different areas, and when positioned at specific angles, they work in conjunction with the fixed air blowing portion to provide comprehensive room coverage. This multi-functionality is achieved without requiring entirely separate systems.
3Ease of operation
If airflow direction vanes are provided at the air blowing opening, then the airflow direction control is improved, but the air blowing range remains limited to one direction
Solution Approach 1:
Instead of using fixed or limited-range airflow direction vanes, the movable air blowing portions rotate about an axis orthogonal to the panel surface, enabling them to change the primary blowing direction. This dynamic adjustment allows the air blowing range to expand from a single direction to multiple directions, effectively solving the limitation of traditional vanes.
Solution Approach 2:
The rotation axis of the movable air blowing portions is positioned orthogonal to the panel surface, adding a new dimension of control. This allows the air blowing direction to be adjusted in a manner that expands coverage across the room, complementing the traditional up/down and left/right vane control for comprehensive airflow management.
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 out in multiple directions, improving airflow coverage and efficiency.
Implementation Method 1
a U-shaped heat exchanger in the main unit... the air sucked from the suction opening can exchange heat with the refrigerant in the heat exchanger
Implementation Method 2
a blowing fan formed of a sirocco fan surrounded by a fan casing in the center of the heat exchanger... the air sucked from the suction opening can be blown out in one direction from the blowing opening

AI summary
In order to quickly condition a room by blowing conditioned air from an air blowing opening over a wide range, a fixed air blowing portion 75 is disposed at a central portion in a raised portion 740 in which a part of a decorative panel 70 is raised toward the air conditioning room. Movable air blowing portions 77 are disposed on both sides thereof. The movable air blowing portion 77 is rotatable within a predetermined angle range around an axis orthogonal to the panel surface of the decorative panel 70 or to the ceiling surface, while air blowing openings 754 and 783 are formed on each side surface of the fixed air blowing portion 75 and the movable air blowing portion 77. As a result, the conditioned air is blown out in a wide range in the horizontal direction from the air blowing opening 783 as the movable air blowing portion 77 rotates.
