Cassette Air Conditioner Suction Grill Support Against Drooping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cassette type air conditioners with larger suction grills face issues where the outer ends tend to droop down due to inadequate support, leading to instability and potential air leakage.
Innovation Solution
The indoor unit incorporates a grill restriction member that couples the suction grill to the panel on both sides, preventing drooping by using fixing and switching members, along with a panel bracket and grill restriction member to maintain the grill's position and ensure proper airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction grill size is increased to improve airflow capacity, then the airflow performance is improved, but the grill becomes unstable and tends to droop down
Solution Approach 1:
The support structure is divided into multiple segments: fixing members at the front and rear ends, and grill restriction members at both sides. This segmentation allows each part to perform its specific function - the fixing members provide anchoring points while the grill restriction members prevent drooping, collectively stabilizing the larger suction grill without compromising airflow capacity
2Stability of the object's composition
If the suction grill is securely fixed to prevent drooping, then the stability is improved, but the maintenance and filter replacement become difficult
Solution Approach 1:
The switching member enables dynamic transformation of the grill's fixed state. When the switching member moves between its first and second positions, it releases the grill restriction members from the panel brackets, allowing the suction grill to be easily removed for maintenance while maintaining stability during normal operation
3Stability of the object's composition
If the grill restriction member is added to prevent drooping, then the stability is improved, but the device complexity increases
Solution Approach 1:
The grill restriction members serve multiple functions: they prevent drooping by restricting the outer ends of the suction grill, act as connection points for easy removal when combined with the switching member, and work cooperatively with the fixing members to provide comprehensive support. This multi-functionality reduces the need for additional separate components
