Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the bezel is fixed in position, then the device structure is simple, but the heat dissipation efficiency is insufficient
Solution Approach 1:
The bezel is designed to be movable rather than fixed, allowing it to rotate between different positions. This dynamic configuration enables the bezel to adjust the airflow path according to different operational states, improving heat dissipation efficiency without requiring a completely complex reconfigurable system. The movable bezel connects to both the cover plate and base, creating a controlled dynamic element that optimizes thermal management.
2Temperature
If the bezel rotates to face the opening portion, then the heat dissipation efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The bezel serves multiple functions: it acts as a structural frame, an airflow control element, and a heat dissipation management component. By making the bezel movable and connecting it to both the cover plate and base, the same component performs both structural support and thermal management functions, reducing the need for additional dedicated heat dissipation structures.
3Temperature
If airflow passes through the opening portion, then heat dissipation is enhanced, but airflow reversal may occur reducing effectiveness
Solution Approach 1:
The movable bezel acts as an intermediary element that controls and directs the airflow path. By rotating to different positions, the bezel mediates between the internal heat-generating components and the external environment, guiding hot air outward through the opening portion and preventing it from reversing back into the device, thus improving heat exchange effectiveness.

AI summary
An electronic device is provided, and the electronic device includes a base, a cover plate, and a bezel. The base has a sidewall where an opening portion is formed. An airflow selectively passes through the opening portion. The cover plate is pivotally connected to the base. The bezel is movably connected to the cover plate, wherein the bezel is rotated facing the opening portion selectively. The arrangement of the bezel may reduce the gap between the bezel and the down edge of the opening portion of the base, reducing the airflow flowing downward back to the heat-dissipation mechanism in the base. Therefore, the heat-dissipation efficiency of the electronic device is enhanced.
