Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed plathy top cover is used, then the structure is simple, but the appearance is stiff and unattractive
Solution Approach 1:
The top cover is transformed from a fixed static structure to a movable dynamic structure that can rotate and tilt, allowing it to change its orientation and position to achieve both aesthetic appeal and functional performance
Solution Approach 2:
The top cover adopts a dome-shaped curved structure instead of a flat planar design, creating a more attractive appearance while also facilitating better airflow discharge and reducing dew formation
2Device complexity
If air outlets are provided in sidewalls, then the structure is simple, but the appearance is stiff and unattractive
Solution Approach 1:
The air outlet is moved from a two-dimensional sidewall opening to a three-dimensional dome-shaped structure with rotational and tilting capabilities, adding spatial dimensions to achieve both aesthetic appeal and functional flexibility
3Device complexity
If the air outlet size is fixed, then the structure is simple, but the control process is complicated when independent door structure is added
Solution Approach 1:
The air outlet door function is merged with the top cover itself, eliminating the need for separate independent door structures. The top cover rotates to close the air outlet, simplifying both the structure and control process
4Ease of operation
If a grille is rotated to regulate air volume and direction, then the air flow can be controlled, but the structure becomes complicated
Solution Approach 1:
The air flow control function is merged with the top cover rotation mechanism. By rotating the top cover to different angles, both air volume and direction are controlled simultaneously, eliminating the need for separate grille structures
5Temperature
If temperature difference exists between air flow and external environment, then air conditioning function is achieved, but dew formation occurs around air outlets
Solution Approach 1:
A heating device is installed around the air outlet to preemptively heat the surrounding area before dew can form. This preliminary heating action prevents condensation by maintaining the temperature above the dew point
Solution Approach 2:
The dome-shaped top cover creates a curved surface that reduces the surface area in contact with cold air, minimizing the areas where dew can form compared to flat surfaces
