Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle interfaces are complex and unclear, making it difficult for occupants to understand their functions, especially in environments lacking ambient light or proper orientation, as existing methods rely on visual cues.
Innovation Solution
Incorporating an electromagnetic transmitter that modulates ultraviolet or infrared spectrum wavelengths to encode data for vehicle control interfaces, allowing tactile user input and providing interface information through a graphical user interface on a mobile device, synchronized with the rolling shutter rate of a CMOS sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual cues are used to display interface definitions and functionality, then occupants can understand interface functions, but the method fails in environments lacking ambient light or proper orientation
Solution Approach 1:
The patent replaces visual optical cues with electromagnetic communication signals. Instead of relying on ambient light and visual displays that fail in dark environments, the system uses electromagnetic transmitters (UV or infrared spectrum) to encode and transmit interface definition data to mobile device sensors, enabling operation independent of visible light conditions
Solution Approach 2:
The patent introduces mobile devices as intermediary components between vehicle interfaces and occupants. The mobile device acts as a mediator that receives electromagnetic signals from transmitters and processes/displayes interface definitions, bridging the gap between the interface and user in various environmental conditions
2Loss of information
If electromagnetic transmitters use visible light spectrum, then transmission can be detected by human eye, but transmission interferes with ambient light requirements and proper orientation needs
Solution Approach 1:
The patent changes the wavelength parameter of electromagnetic transmission from the visible light spectrum to ultraviolet or infrared spectra. This parameter change allows the transmission to occur outside the visible range, eliminating dependence on ambient visible light and proper orientation, while still enabling reliable data transmission through electromagnetic modulation detectable by mobile device sensors
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clear and intuitive operation of vehicle interfaces by transmitting encoded data via electromagnetic signals, accessible through a mobile device, even in low-light conditions, enhancing occupant interaction and reducing interface complexity.
Implementation Method 1
A controller is configured to modulate output having ultraviolet or infrared spectrum wavelength of an electromagnetic transmitter at a receiver capture rate to encode data into the output
Implementation Method 2
A method by a controller includes displaying, on a graphical user interface, information related to a control interface based on an identification of the control interface such that operation of the control interface is disclosed. The display is responsive to receiving an electromagnetic output being modulated according to a capture rate of a sensor having a wavelength within an ultraviolet or an infrared spectrum
