Radar Signal Direction and Strength Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current police radar detectors do not efficiently and effectively convey all available information about detected radar signals to drivers, particularly regarding signal strength and direction, especially when traveling at high speeds.
Innovation Solution
A device with a radar signal detector that determines signal strength and direction, coupled with a display that provides a single visual region whose appearance varies based on both factors, allowing for concurrent visual indication of signal strength and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple separate display regions are used to show signal strength and direction, then each parameter can be displayed clearly, but the overall display complexity increases and information delivery speed decreases
Solution Approach 1:
The patent combines signal strength indication and direction indication into a single display region. The display shows both parameters simultaneously using integrated visual elements, eliminating the need for separate display areas and reducing overall display complexity while maintaining complete information delivery.
Solution Approach 2:
The single display region serves multiple functions by simultaneously indicating both signal strength and direction. The display elements are designed to convey multiple pieces of information through different visual characteristics (such as color, brightness, or pattern variations) within one unified region, improving information delivery efficiency.
2Reliability
If detailed information about radar signals is provided, then driver awareness is improved, but the time to process information increases
Solution Approach 1:
The patent utilizes color variations to encode multiple pieces of information about radar signals. Different colors or color intensities indicate different signal strengths and directions, allowing drivers to quickly interpret detailed information through immediate visual perception rather than sequential reading, thus reducing processing time while maintaining comprehensive awareness.
Solution Approach 2:
The display transitions from one-dimensional sequential information presentation to two-dimensional simultaneous visual indication. By using spatial arrangement and visual dimensionality within the single display region, the system presents multiple parameters at once, enabling drivers to process information faster while maintaining detailed awareness.
3Loss of information
If the display shows all available radar information, then completeness is improved, but the visual clutter increases making it harder to interpret
Solution Approach 1:
The single display region is segmented into distinct visual zones or elements that separately indicate signal strength and direction. This segmentation allows the display to present complete information while organizing it into interpretable sections, reducing visual clutter through structured arrangement and making it easier for drivers to quickly understand the radar signal characteristics.
Data Source
AI summary
A device includes a radar signal detector that can determine a signal strength of a police radar signal and a direction of a source of the police radar signal. Additionally, the device includes a display in communication with the radar signal detector that provides a single display region having a visual appearance which varies based on both the direction and on the signal strength.
