Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wall-mounted air conditioners are limited by their stripe-shaped design, which restricts airflow and temperature adjustment, failing to meet modern aesthetic and performance requirements.
Innovation Solution
A wall-mounted air conditioner with a circular or approximately circular indoor unit design featuring an arc surface, an inclined air outlet, and a unique flow air apparatus that includes sequentially arranged airduct bodies and a centrifugal fan, allowing for efficient air direction and temperature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional stripe-shaped design is used, then the structure is simple and easy to manufacture, but the airflow capability and temperature adjustment are limited
Solution Approach 1:
The patent applies spheroidality by designing the indoor unit with a circular or approximately circular orthographic projection instead of the traditional stripe shape. The front housing features an arc surface where the upper and lower portions contract backwards while the middle portion protrudes forwards, creating a curved, three-dimensional structure that improves airflow capability while maintaining aesthetic appeal
2Productivity
If the air outlet is positioned at the front, then the structure is traditional and simple, but the air flow capability and temperature adjustment are restricted
Solution Approach 1:
The patent applies inversion by positioning the air outlet at the lower portion of the front housing instead of the traditional front center position. The air outlet is configured with an inclined direction where the upper portion is forward and the lower portion is backward at an angle of 4°-45°, enabling improved temperature adjustment and airflow distribution while maintaining installation flexibility
3Volume of moving object
If the housing size is minimized, then the installation space is reduced, but the space for internal components and airflow paths is limited
Solution Approach 1:
The patent applies nesting by arranging the rear housing within the limiting area of the front housing, with the outer profile curve of the rear housing located inside the outer profile curve of the front housing. This nested configuration minimizes the overall housing volume while providing sufficient space for heat exchangers, flow air apparatus, and airflow paths, achieving both compact installation and efficient airflow
