Solution Overview
Problem
Conventional air conditioners face challenges in providing intense, concentrated air flow in narrow regions and suffer from aesthetic and efficiency issues due to gaps between cover and body components, which affect air flow and user accessibility.
Innovation Solution
The design incorporates a unique airflow converter and discharge port configuration using the Coanda effect, with a truncated cone shape and strategically positioned discharge ports to enhance airflow concentration and user accessibility by minimizing gaps between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap between the cover and main body is increased to allow user hand access, then ease of operation is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The cover separation unit is divided into multiple segments including a first cover pusher, second cover pusher, and lever components. This segmentation allows the cover to be separated through a mechanical linkage system that requires minimal gap while maintaining aesthetic appearance when coupled.
Solution Approach 2:
A lever acts as an intermediary mechanical element between the user's hand and the cover separation mechanism. The lever translates user input into cover separation motion through a compact linkage, enabling operation with minimal gap between cover and main body.
2Shape
If the cover and main body are coupled without gap using magnetic force or hook, then aesthetic appearance is improved, but ease of operation deteriorates due to difficulty in separation
Solution Approach 1:
The coupling mechanism extracts the separation function from direct manual manipulation and implements it through a dedicated cover separation unit with pushers and levers. This allows tight coupling for aesthetics while providing an engineered separation mechanism for ease of operation.
Solution Approach 2:
The cover separation unit is designed to be self-actuating through the lever mechanism. When the lever is operated, it automatically activates the cover pushers to separate the cover, eliminating the need for complex external tools or mechanisms.
3Area of stationary object
If an axial fan is used to provide wide air flow coverage, then air flow distribution is improved, but air flow concentration in narrow region deteriorates
Solution Approach 1:
The air guide is designed with locally optimized geometry including curved surfaces and strategically positioned discharge ports. These local structural features concentrate air flow in specific narrow regions while the overall system maintains wide coverage through multiple discharge locations.
Solution Approach 2:
The air guide incorporates curved surfaces and rounded geometries to smoothly direct and concentrate air flow. The curved structure helps focus air streams in narrow regions while distributing coverage across wider areas through controlled flow paths.

AI summary
Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.
