Computer desk

The patent applies the dynamics principle by implementing a turning device with rotary shafts and connecting rods that enables the display to dynamically change between upright and flat positions. The first rotary shaft allows the desktop supplementary board to rotate between a first position (in the accommodating gap) and a second position (below the desktop), while the second rotary shaft enables the display to rotate relative to the second rotary shaft. This dynamic mechanism resolves the contradiction by providing both operational comfort when flat and positional versatility when upright.

The patent applies the dimensionality change principle by moving the display from the horizontal desktop plane to a vertical or inclined plane when in upright position. The turning device enables the display to be positioned below the desktop surface or at an angle, effectively utilizing three-dimensional space rather than occupying valuable horizontal desktop area. This resolves the contradiction by providing flat touch operation capability when needed while maintaining a clutter-free desktop surface when the display is upright.

The patent applies the merging principle by integrating multiple functions into a unified turning device structure. The first rotary shaft, second rotary shaft, connecting rods, and rotating rings are combined into a single coordinated mechanism that simultaneously controls the position of both the desktop supplementary board and the display. This merging approach resolves the contradiction by achieving display position flexibility through an integrated system rather than separate mechanisms, reducing overall structural complexity while maintaining versatility.
