Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the frame size of the display apparatus is reduced, then the antenna size is constrained, but the radar device cannot detect hand gestures effectively at a distance
Solution Approach 1:
The patent divides the display area into multiple subpixel regions and inter-subpixel regions, placing antennas specifically in the inter-subpixel regions. This segmentation allows the antenna system to utilize previously wasted space between pixels, enabling effective gesture detection without increasing the overall frame size.
Solution Approach 2:
The patent transitions from considering only the peripheral area for antenna placement to utilizing the two-dimensional inter-subpixel regions across the display area. By distributing multiple antennas throughout the inter-subpixel regions rather than concentrating them in one location, the system achieves better detection coverage and accuracy within the same frame boundaries.
2Measurement precision
If the antenna size is increased to improve gesture detection, then the frame size must be increased, but the display apparatus should maintain a compact form
Solution Approach 1:
Instead of using a single large antenna that would increase frame size, the patent segments the antenna system into multiple smaller antennas distributed across the inter-subpixel regions. Each antenna is small enough to fit within the inter-subpixel space, yet collectively they provide comprehensive gesture detection coverage.
Solution Approach 2:
The patent combines multiple small antennas into a unified antenna system that functions together for gesture detection. By merging the detection capabilities of multiple distributed antennas, the system achieves the sensitivity and accuracy of a larger antenna without the space requirements.
3Speed
If the radar device operates at high frequency to detect gestures at a distance, then detection range is improved, but power consumption increases
Solution Approach 1:
The patent uses multiple antennas operating at moderate power levels rather than a single antenna operating at maximum power. By distributing the detection function across multiple partial elements (antennas), each operating at lower power, the system achieves the same overall detection capability with reduced total power consumption.
