Indoor Unit Suction Grill Assembly for Easy Removal and Air Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioner indoor units face difficulties in efficiently attaching and detaching suction grills, require extensive working time for assembly and disassembly, and have limited air suction capabilities, leading to inefficient air circulation.
Innovation Solution
The indoor unit design includes a detachable suction grill and filter assembly, where the suction grill is fixed to the front frame using an elastic connection, allowing for easy attachment and detachment, and air is sucked from multiple directions through a combination of front and rear suction holes, enhancing air circulation and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the suction grill is integrally formed with the suction panel, then the structural strength is improved, but the ease of attachment and detachment deteriorates
Solution Approach 1:
The suction grill is separated from the suction panel, allowing the grill to be detachably mounted while the panel remains fixed. This segmentation enables the grill to be easily removed for cleaning or replacement without damaging the panel structure, resolving the contradiction between structural integrity and ease of maintenance.
Solution Approach 2:
The suction grill is designed with dynamic mounting characteristics - firmly attached during operation to maintain structural strength, but easily detachable when needed for maintenance. The detachable mounting mechanism allows the system to transition between static (during operation) and dynamic (during maintenance) states.
2Ease of operation
If the suction grill is detachably mounted, then the ease of attachment and detachment is improved, but the structural strength deteriorates
Solution Approach 1:
By separating the suction grill from the suction panel into distinct components with a detachable connection mechanism, the design achieves both ease of attachment/detachment and adequate structural strength during operation. The segmentation allows for simple mounting while maintaining integrity when assembled.
3Device complexity
If air is sucked only from the front, then the device complexity is reduced, but the air circulation efficiency deteriorates
Solution Approach 1:
The air suction capability is extended from a single front direction to multiple dimensions by adding rear suction holes. This multi-directional suction approach improves air circulation efficiency and coverage without significantly increasing device complexity, as the additional holes are integrated into the existing grill structure.
4Ease of operation
If the filter is installed separately from the suction grill, then the ease of filter replacement is improved, but the assembly complexity deteriorates
Solution Approach 1:
The filter is coupled with the suction grill to form an integrated assembly, allowing both components to be attached or detached together as a single unit. This merging simplifies the overall assembly process while maintaining ease of filter replacement, as the filter moves with the grill during maintenance operations.
