Cassette Air Conditioner Indoor Unit With Sliding Suction Grill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cassette type air conditioner indoor units face challenges in easily opening and closing the suction grill due to its shape and coupling structure, which can interfere with the panel, making it difficult to mount and maintain.
Innovation Solution
The indoor unit design features a suction grill with concave parts matching the inner line of discharge holes, a round groove connecting discharge holes and vanes, and a connection member that slides and rotates to open or close without interference, allowing for easy access and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction grill is rotatably coupled to the panel using a hinge, then the suction grill can be opened or closed, but the suction grill may interfere with the panel edges or protruding parts, making it difficult to mount and operate
Solution Approach 1:
The suction grill is divided into multiple sections that can move independently, allowing each segment to navigate around panel edges and protruding parts during opening and closing operations, thus avoiding interference while maintaining functionality
Solution Approach 2:
The suction grill transitions from a simple rotational movement in one dimension to a combined sliding and rotating motion in multiple dimensions, enabling it to clear obstacles on the panel surface during operation
2Shape
If the suction grill covers the entire panel surface, then the exterior appearance is improved, but the suction grill becomes difficult to open and close due to interference with panel features
Solution Approach 1:
The suction grill employs a dynamic coupling mechanism that allows it to adapt its movement path during opening and closing, transitioning between different motion modes to avoid static interference with panel features while maintaining full surface coverage when closed
3Device complexity
If the suction grill is designed with a simple coupling structure, then the device complexity is reduced, but the suction grill may interfere with panel edges, making it difficult to mount and maintain
Solution Approach 1:
A connection member is introduced as an intermediary component between the suction grill and panel, facilitating easy attachment and detachment while preventing interference with panel edges, thus improving both mounting ease and maintainability without adding significant complexity
