Solution Overview
Problem
The existing easily openable and closable structure for the lid body covering the emergency operation switch in air-conditioning apparatuses is not suitable, as it allows users to easily manipulate the switch, which is not intended for normal conditions.
Innovation Solution
A ceiling-concealed air-conditioning apparatus design featuring a decorative panel with a suction grille and a side panel that includes an openable and closable cover with a protruding portion, where the cover can only be opened by pulling the protruding portion downward when the suction grille is open, preventing easy access to the emergency operation switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid body is made easily openable and closable to facilitate user operation, then the ease of operation is improved, but the emergency operation switch becomes easily accessible which is not intended under normal conditions
Solution Approach 1:
The lid body is divided into two separate lids: a first lid covering the operation start/stop switch and a second lid covering the emergency operation switch. This segmentation allows different access control mechanisms for normal and emergency operations, resolving the contradiction by enabling easy access to the first lid while maintaining restricted access to the second lid.
Solution Approach 2:
The second lid is configured to be movable between a closed position and an open position, adding a dimensional aspect to access control. The lid includes a through hole that is covered when closed and exposed when open, creating a spatial dimension for controlling access to the emergency switch while maintaining ease of operation when needed.
2Object-affected harmful factors
If the lid body covering the emergency operation switch is made difficult to open to prevent easy manipulation, then the security of the emergency switch is improved, but the ease of operation deteriorates
Solution Approach 1:
By separating the lid into two distinct lids with different access characteristics, the invention allows the first lid to be easily openable for normal operations while the second lid provides restricted access to the emergency switch, thus resolving the contradiction between security and ease of operation.
Solution Approach 2:
The through hole in the second lid acts as an intermediary element that can be covered or exposed based on the lid position. This intermediary structure allows the emergency switch to be protected when the lid is closed while still permitting access when the lid is intentionally opened, balancing security and operational accessibility.

AI summary
Provided is a ceiling-concealed air-conditioning apparatus, including: an air-conditioning apparatus main body having an air inlet formed in a lower portion thereof; an electrical component box arranged on a side of the air-conditioning apparatus main body, and includes a switch configured to operate the air-conditioning apparatus main body, and arranged on a lower portion of the electrical component box; and a decorative panel arranged below the air-conditioning apparatus main body and the electrical component box to serve as a decorative surface, the decorative panel including: a suction grille arranged so as to be openable and closable and configured to cover the air inlet; and a side panel arranged below the electrical component box, the side panel including an openable and closable cover arranged so as to be openable and closable and configured to cover the switch when the openable and closable cover is closed, the openable and closable cover including a protruding portion protruded on a side portion of the openable and closable cover on the suction grille side, in which the openable and closable cover is opened by pulling the protruding portion downward under a state in which the openable and closable cover is closed, and in which the protruding portion is covered by the suction grille when the suction grille is closed, and the protruding portion is exposed to an outside when the suction grille is opened.
