Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projection device is placed close to the desktop for vertical projection, then the device structure is simplified and convenience is improved, but the air inlet and outlet are blocked by the desktop, affecting heat dissipation performance
Solution Approach 1:
The air outlet is divided into multiple independent outlets (first air outlet and second air outlet) located at different positions on the casing. This segmentation allows the device to discharge hot air through different paths, ensuring that at least one outlet remains unobstructed regardless of placement position, thus maintaining heat dissipation performance while enabling close placement to the desktop.
Solution Approach 2:
The air outlets are distributed in three-dimensional space at different locations on the casing rather than concentrated at a single position. This spatial distribution across multiple dimensions ensures that obstacles like desktops cannot block all air outlets simultaneously, allowing the device to maintain effective heat dissipation in various placement orientations including vertical projection close to the desktop.
2Reliability
If an external mounting part is added to increase distance from the desktop, then heat dissipation performance is maintained, but the device complexity increases and placement flexibility is reduced
Solution Approach 1:
The air outlet function is extracted from a single location and distributed across multiple outlets at different positions on the casing. This extraction eliminates the need for external mounting parts to maintain distance from obstacles, as the distributed outlet configuration inherently provides obstruction resistance. The solution achieves heat dissipation reliability through the casing structure itself without adding external mounting components.
Solution Approach 2:
The multi-outlet air outlet structure serves multiple functions: it provides heat dissipation capability, ensures obstruction resistance in various placement positions, and eliminates the need for external mounting parts. This universal design allows the device to maintain heat dissipation performance while achieving placement flexibility and structural simplicity simultaneously.
3Device complexity
If the air outlet is positioned close to the desktop, then the device structure is simplified, but hot air circulation is blocked, causing continuous heating of elements
Solution Approach 1:
The air outlet is segmented into multiple independent outlets positioned at different locations on the casing. This segmentation ensures that even when the device is placed close to the desktop, at least one outlet remains unobstructed, allowing hot air to escape and preventing continuous circulation blockage that would cause element overheating.
Solution Approach 2:
The baffle structure acts as an intermediary component that guides and directs airflow from the first area to the second area, facilitating hot air discharge through the distributed outlets. The baffle ensures proper airflow paths are maintained even in close proximity to obstacles, preventing temperature buildup while maintaining structural simplicity.
