Ceiling AC Decorative Panel Recess Layout for Hidden Suction Grill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing decorative panels for ceiling-mounted air conditioning units have a suction grill with rectangular suction holes that make the space behind them visible from a distance, impairing the aesthetic appeal of the indoor space, and existing solutions require additional coloring steps to address this issue, increasing manufacturing complexity.
Innovation Solution
A decorative panel with a suction grill featuring a grid-shaped grill body and recesses in its lower surface, where the recesses are arranged to surround the grill body and have a decreasing opening area, creating a shadow that obscures the boundary between the grill and its surrounding area, thereby improving the design without adding manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If rectangular suction holes are used in the suction grill, then the suction port appears dark and the space behind is visible from a distance, but this impairs the aesthetic appeal of the indoor space
Solution Approach 1:
The invention transitions from a flat two-dimensional suction grill design to a three-dimensional structure by adding recesses that extend downward from the front surface. These recesses create depth and shadow effects that obscure the dark interior space behind the grill, improving aesthetics without requiring additional coloring steps or complex assemblies.
Solution Approach 2:
The recesses in the decorative panel create optical effects by capturing and diffusing light, making the suction port area appear lighter and less dark. This achieves a visual effect similar to coloring but through structural design alone, avoiding additional manufacturing steps.
2Illumination intensity
If the lower surface of the decorative panel is colored to gradually lighten outward from the center portion, then the boundary between the dark suction port and surrounding portion is obscured, but this requires an additional coloring step that increases the number of manufacturing process steps
Solution Approach 1:
Instead of changing the color parameter through additional coating steps, the invention changes the geometric parameter by introducing recesses with varying depths. The recesses have different opening areas that create a gradual brightness transition effect, achieving the desired visual gradient through structural variation rather than color application.
3Shape
If the suction grill is designed with a grid shape and recesses surrounding the grill body, then the boundary between the grill and surrounding area is obscured and aesthetic appeal is improved, but this increases the complexity of the suction grill structure
Solution Approach 1:
The invention merges the decorative function with the structural function of the suction grill. The recesses are integrated into the grill body as a unified structure rather than being added as separate decorative elements. This combination achieves aesthetic improvement while minimizing the increase in structural complexity.
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 solution effectively enhances the aesthetic appeal of the indoor space by making the suction grill appear lighter and integrated, while maintaining airflow efficiency and avoiding increased manufacturing complexity.
Implementation Method 1
a shadow cast by those recesses (81) arranged along the grill body (61) obscures the boundary between the dark grill body (61) and a portion surrounding the grill body (61)

AI summary
Disclosed herein is a decorative panel for a ceiling-mounted indoor unit of an air conditioning device, and the panel is configured to improve the design of a suction grill without increasing the number of manufacturing process steps. The decorative panel includes: a panel body having a suction port; and a suction grill attached to the suction port of the panel body. The suction grill has a grill body which is formed in the shape of a grid to have a large number of suction holes and is positioned over the suction port. A large number of recesses are formed in a lower surface of the decorative panel so as to be arranged along, and to surround, the grill body.
