Engineering Contradiction Analysis
1Adaptability or versatility
If measurement devices use conventional two-dimensional display units to output measured results, then the display structure remains simple and easy to manufacture, but the device cannot effectively display high frequency signals with more than two parameters simultaneously
Solution Approach 1:
The patent applies dimensionality change by encoding multi-dimensional measurement data (amplitude, frequency, time) into a two-dimensional visual representation using image point density. The coding unit transforms 3D or 4D measurement tuples into 2D visual patterns where the density of pixels represents additional dimensions, allowing complex multi-parameter data to be displayed on conventional 2D screens without requiring advanced display hardware.
Solution Approach 2:
The invention changes the parameter representation by encoding signal amplitude into image point density rather than using traditional intensity or color scaling. This parameter transformation allows the display to represent multiple parameters (amplitude, frequency, time) simultaneously by varying the density of displayed pixels in different regions, thereby increasing display versatility while maintaining simple hardware.
2Loss of information
If the measurement apparatus encodes high frequency signal amplitude as image point density with adjustable pixel density, then the visualization of complex signal data is enhanced, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent segments the measurement data processing by dividing the display area into multiple regions, each representing different parameter ranges. The coding unit processes measurement tuples by segmenting them into discrete visual elements (pixels or image points) whose density varies according to the encoded parameters. This segmentation approach allows complex multi-dimensional data to be represented through simple density variations rather than requiring complex processing of continuous data streams.
3Ease of operation
If conventional measurement devices display only two parameters simultaneously on a two-dimensional screen, then the display operation remains simple, but the ability to analyze multi-dimensional signal data is limited
Solution Approach 1:
The patent introduces an intermediary coding unit that acts as a mediator between the multi-dimensional measurement data and the two-dimensional display. This coding unit transforms complex measurement tuples into visual patterns using image point density as an intermediate representation. The intermediary layer allows the simple 2D display to convey complex multi-parameter information by encoding additional dimensions into the density distribution of displayed pixels, thereby maintaining operational simplicity while preserving information completeness.
