Indoor AC Panel Assembly With Guided Door and Split Front Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner indoor units face high production costs, inefficiencies, and reliability issues due to large, integrally formed front panels and unstable doors, which also limit ventilation options.
Innovation Solution
The design includes independently processed and molded first and second panels with a door mounting plate and guiding mechanism, allowing for reduced mold size and cost, improved production efficiency, and enhanced reliability, along with adjustable ventilation options through strategically arranged air outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the front panel is integrally formed using a large injection mold, then the structural integrity is improved, but the manufacturing cost increases and production efficiency decreases
Solution Approach 1:
The front panel is divided into multiple smaller panels that are independently molded and then assembled together. This segmentation allows each panel to be manufactured separately using smaller injection molds, reducing mold cost and production time while maintaining overall structural integrity through proper connection design between panels.

3Adaptability or versatility
If the door is made movable to enable opening and closing, then the ventilation control is improved, but the reliability decreases due to instability
Solution Approach 1:
A door mounting plate is introduced as an intermediary component between the door and the panel assembly. The door mounting plate provides stable mounting and positioning for the door, ensuring reliable operation while allowing the door to remain movable for ventilation control. This intermediary structure resolves the conflict between movability and stability.

AI summary
An air conditioner indoor unit includes a back plate assembly, a top cover assembly having a part connected to a top wall of the back plate assembly, and a panel assembly. The panel assembly includes a first panel connected to the back plate assembly and including a first air outlet and a second air outlet arranged below the first air outlet, a second panel disposed below the first panel, a door mounting plate disposed at rear of the first panel and including a guiding groove, a door coupled to the door mounting plate and movable relative to the door mounting plate to open or close the first air outlet, and a guiding post arranged at the door and configured to extend into and slide relative to the guiding groove. The back plate assembly, the top cover assembly, the first panel, and the second panel are connected one to another.
