Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional stripe-shaped indoor unit is used, then the structure is simple and easy to manufacture, but the airflow capability and temperature adjustment performance 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, aerodynamic form that enhances airflow capability while maintaining manufacturing feasibility
Solution Approach 2:
The patent segments the air delivery system into multiple functional components: a centrifugal fan for air generation, a volute for air collection and direction, and an air delivery apparatus with multiple air-duct bodies arranged sequentially. This segmentation allows each component to be optimized for its specific function, improving overall airflow performance while maintaining modular manufacturability
2Ease of operation
If the air outlet is positioned in the lower portion with inclined direction, then the air flow direction is improved for better indoor air adjustment, but the housing design becomes more complex
Solution Approach 1:
The patent applies asymmetry by positioning the air outlet in the lower portion of the front housing with a specific inclined direction (4°-45°) where the upper portion is forward and the lower portion is backward. This asymmetric outlet configuration optimizes air flow direction for better temperature distribution in the room, while the housing design uses symmetric circular projection to balance the complexity
Solution Approach 2:
The patent utilizes dimensional changes by creating a three-dimensional arc surface on the front housing where the upper and lower portions contract backwards and the middle portion protrudes forwards. This dimensional manipulation allows the air outlet to be positioned in the lower portion with optimal inclination while maintaining a compact overall housing structure that meets installation space requirements
3Shape
If a circular or approximately circular design is adopted, then the appearance is unique and aesthetic demands are met, but the installment position limitations and space requirements increase
Solution Approach 1:
The patent employs spheroidality by designing the indoor unit with a circular or approximately circular orthographic projection, providing a unique and aesthetically pleasing appearance that meets modern design requirements. The arc surface configuration with upper and lower portions contracting backwards and the middle portion protruding forwards creates a compact form factor that optimizes space utilization for wall mounting installations
