E-ink Smart Ring for Driver Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle console displays are large and require drivers to gaze at the console, which can be hazardous, especially in conditions like congested traffic or inclement weather. Additionally, using cellular devices for information while driving is illegal in some regions and can be distracting.
Innovation Solution
A smart ring device with an e-ink display that can be worn by a driver, allowing for the presentation of various driving conditions and biometric information without requiring the driver to take their hands off the wheel or look away from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional vehicle console displays are used to provide driving information, then drivers can access information about driving conditions, but drivers must gaze at the console which creates safety hazards and distraction
Solution Approach 1:
The patent moves the display interface from the traditional 2D console plane to the driver's finger via a smart ring wearable device. This dimensional shift allows information to be presented in the driver's peripheral vision or tactile field without requiring gaze diversion from the road, effectively adding a spatial dimension to information delivery that eliminates the distraction problem while maintaining information accessibility.
2Loss of information
If cellular devices are used to display driving information, then drivers can access comprehensive information, but this is illegal in some regions and causes distraction
Solution Approach 1:
The patent extracts the essential information display function from the driver's hands and separates it from prohibited devices like cell phones. By placing a minimal display interface on the smart ring worn on the finger, the system provides necessary driving information without requiring the driver to hold or interact with a cellular device, thus maintaining legal compliance while ensuring safety.
3Loss of information
If large console displays are used to present driving information, then information is visible to drivers, but the displays require drivers to shift their gaze from the road
Solution Approach 1:
The patent applies local quality by placing a small, focused display interface directly on the driver's finger rather than using a large console display. This localized approach delivers information precisely where the driver can perceive it through peripheral vision or tactile sensation without requiring attention shifts, making the information presentation adapted to the driver's natural focus zone.
4Loss of information
If traditional display technologies are used in smart ring devices, then information can be displayed, but power consumption would be excessive for a wearable device
Solution Approach 1:
The patent changes the display technology parameter from traditional high-power displays (LCD, OLED) to e-ink display technology. E-ink displays consume power only when updating the display content, not during static display periods, dramatically reducing average power consumption while maintaining readable information display capability suitable for a battery-constrained wearable device like a smart ring.
Data Source
AI summary
A system for displaying information via a smart ring device can include a smart ring device. The smart ring device also can include a processor disposed within a ring band. The processor can be configured to collect data to identify one or more conditions. The one or more conditions can include one or more of a biometric of a user of the smart ring device, a state of the user of the smart ring device, or a condition of an environment of the user of the smart ring device. The smart ring device further can include a display at a surface of the ring band. The processor can be configured to cause the display to present the information indicative of the one or more conditions. The processor also can be configured to determine whether a termination condition has been met for the one or more conditions.
