Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing decorative-panel mounting components in air-conditioning apparatuses require significant force to rotate the decorative-panel mounting screw, making the mounting process less efficient due to the need for elastic deformation of curved parts, which complicates the operation.
Innovation Solution
A decorative-panel mounting component design featuring first and second mounting plate parts with a movable mounting surface part, first and second protruding engagement parts, and recessed engagement parts that allow the component to deform and move closer when the decorative-panel mounting screw is fastened, facilitating easier screw insertion without requiring excessive force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the curved part is made elastically deformable to allow displacement of the mounting surface part, then the mounting component can be retained on the decorative panel, but a large force is required to rotate the screw, reducing ease of operation
Solution Approach 1:
The mounting component is divided into a rigid body portion and a separate elastic curved portion. The rigid body portion contains the screw locking hole and maintains structural stability, while the elastic curved portion provides the necessary deformation capability. This segmentation allows the rigid part to retain the mounting component securely while the elastic part accommodates screw insertion without requiring excessive force.
Solution Approach 2:
The elastic curved portion is extracted as a distinct functional element from the rigid body portion. This extraction allows the elastic portion to be optimized independently for deformation characteristics, while the rigid body portion is optimized for retention and structural integrity. The separation enables the screw insertion mechanism to utilize elastic deformation without compromising the overall stability of the mounting component.
2Ease of manufacture
If the mounting surface part is displaced toward the indoor-unit body through elastic deformation, then the decorative panel can be mounted, but the operation becomes complex and less efficient
Solution Approach 1:
The elastic curved portion is pre-formed with specific geometric characteristics that enable automatic deformation during screw insertion. The curvature and material properties are predetermined during manufacturing, so that when the screw is inserted, the elastic portion naturally deforms to the required extent without requiring complex manual manipulation or additional mechanisms.
Solution Approach 2:
The elastic curved portion utilizes changes in physical parameters (elastic deformation) to achieve the displacement of the mounting surface part. By selecting appropriate material properties and geometric parameters for the curved portion, the system transforms the mounting operation into a simple screw insertion process that automatically induces the necessary displacement through elastic deformation, rather than requiring complex mechanical mechanisms.

AI summary
Operation of fastening a decorative-panel mounting screw into a screw-fastening hole of an indoor-unit body is facilitated.A decorative panel includes a decorative-panel body, a decorative-panel mounting component, and a decorative-panel mounting screw. The decorative-panel mounting screw is used to, when the decorative-panel mounting screw is inserted through a second screw-insertion hole in the decorative-panel mounting component and a first screw-insertion hole in the decorative-panel body and fastened into a screw-fastening hole, cause a first mounting plate part and a second mounting plate part included in the decorative-panel mounting component to deform such that a mounting surface part included in the decorative-panel mounting component is displaced toward an indoor-unit body, and cause a first protruding engagement part and a second protruding engagement part included in the decorative-panel mounting component to move to be closer toward each other than before the decorative-panel mounting screw is fastened into the screw-fastening hole.
