Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple displays are arranged in parallel to output three-dimensional images, then depth perception and spatial impression are improved, but device complexity increases
Solution Approach 1:
The display system is segmented into multiple independent display units (first display and second display) arranged in parallel. Each display can independently output graphic objects, allowing the system to create three-dimensional effects through coordinated operation of separate segments rather than requiring a single complex display unit.
Solution Approach 2:
The patent transitions from traditional single-plane two-dimensional display to a multi-plane three-dimensional display configuration. By arranging displays in parallel along a spatial dimension and controlling graphic objects to appear at different depths, the system adds a depth dimension to the display output, enabling true three-dimensional image perception.
2Measurement precision
If graphic objects are alternately output between displays to create three-dimensional effect, then spatial impression is improved, but image output stability deteriorates
Solution Approach 1:
The controller implements periodic alternation in outputting graphic objects between the first and second displays. This rhythmic, alternating display pattern creates a stroboscopic effect that the human visual system integrates into a stable three-dimensional perception, maintaining image stability while achieving spatial depth.
Solution Approach 2:
The system incorporates timing control and coordination mechanisms that monitor and adjust the alternating output between displays. By synchronizing the periodic action with human visual perception characteristics and maintaining consistent alternation patterns, the system ensures stable three-dimensional image output without flicker or instability.
3Measurement precision
If displays are arranged with predetermined distance for three-dimensional output, then depth effect is improved, but area occupied increases
Solution Approach 1:
Instead of expanding the display area horizontally or vertically in a single plane, the patent utilizes the depth dimension by arranging displays along the optical axis. This vertical stacking in the depth direction creates three-dimensional effects while maintaining a compact horizontal and vertical footprint, effectively trading depth for area in a space-efficient manner.
Solution Approach 2:
The patent employs thin, flat display units arranged in parallel layers. These thin-film display structures minimize the lateral area occupied while maintaining the necessary separation distance for three-dimensional effects. The thin-profile design allows compact integration without sacrificing the depth spacing required for spatial perception.
