Solution Overview
Problem
Decorative panels with air supply grilles are prone to falling from their openings due to aged deterioration, which is not effectively addressed in existing technologies.
Innovation Solution
A decorative panel design featuring a frame portion with a contact portion that securely attaches the air supply grille to the grille opening, utilizing an upper surface of the frame to contact a lower surface of the contact portion, thereby preventing the grille from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an air supply grille is attached to a grille opening using conventional methods, then the grille can be installed and function, but the grille may fall from the opening due to aged deterioration
Solution Approach 1:
The attachment mechanism is divided into separate components: a contact portion protruding from the grille and a corresponding contact area on the frame portion. This segmentation allows for modular replacement and maintenance while improving overall attachment reliability through distributed contact points
Solution Approach 2:
The frame portion and contact portion are designed with predetermined geometric shapes and dimensions that ensure proper alignment and engagement before actual attachment occurs. The contact portion is pre-positioned to engage with the frame portion, preventing the grille from falling even after aging
2Ease of operation
If the air supply grille is detachably provided in the grille opening, then the grille can be removed and reinstalled, but the attachment stability may be compromised
Solution Approach 1:
The attachment system transitions from a static fixed connection to a dynamic detachable connection that maintains stability through controlled engagement. The contact portion can be easily inserted and removed, yet when engaged, the geometric fit between the contact portion and frame portion provides stable attachment
Solution Approach 2:
The contact portion acts as an intermediary element between the grille and the frame portion. This intermediate component facilitates easy detachment while maintaining stable attachment when engaged, as it provides a dedicated interface for the detachable connection

AI summary
A decorative panel includes a front surface, a rear surface, a grille opening, a frame portion, and an air supply grille. The grille opening is surrounded by the frame portion, and the air supply grille includes an air supply slit, an air supply slit opening, an outer air supply blowing unit, and a contact portion. The air supply grille is detachably provided in the grille opening, and air is supplied from a rear surface side to a front surface side through the air supply slit opening. The outer air supply blowing unit forms a passage of the air supplied from the air supply slit opening, and the air supply grille is attached to the grille opening by bringing an upper surface of the frame portion into contact with a lower surface of the contact portion.
