Vehicle Display Integrating Time Dependency on Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle dashboard displays often require separate instruments to show the change in numerical values over time, increasing complexity and distracting drivers from the primary task of driving, as the relationship between the actual value and its change is unclear when displayed separately.
Innovation Solution
A device that integrates the display of a numerical value and its time dependency on the same scale, using a controller to show the time dependency as a pattern or progression adjacent to the numerical value, allowing drivers to view both clearly and coherently, with patterns indicating increases or decreases through graphical representations simulating wave movements or distortions.

Engineering Contradiction Analysis
1Loss of information
If separate pointer instruments or additional displays are used to show the change in numerical values over time, then the time dependency information is displayed, but the device complexity increases and driver distraction increases
Solution Approach 1:
The patent combines the display of actual numerical values and their time dependency (rate of change) into a single integrated pointer instrument. The pointer shows the actual value while an afterimage or trail effect visually represents the rate of change, merging two information streams into one coherent display that reduces complexity while maintaining full information content.
Solution Approach 2:
The patent adds a temporal dimension to the traditional pointer display by incorporating afterimage effects that persist for certain durations. This creates a visual trail that represents change over time, transforming a static value display into a dynamic representation that includes time dependency without requiring separate instruments.
2Loss of information
If separate pointer instruments are used to display the rate of change, then the time dependency is shown, but the driver has to look at the instrument cluster longer and is distracted from driving
Solution Approach 1:
By merging the rate of change information into the main pointer display through afterimage effects, the patent allows drivers to perceive both actual values and their changes in a single glance at the primary instrument, eliminating the need to shift attention between multiple displays and reducing overall viewing time.
Solution Approach 2:
The afterimage effect acts as an intermediary that visually encodes the rate of change within the pointer's movement path. This intermediary representation allows drivers to intuitively grasp changes over time without requiring separate displays or prolonged observation, as the afterimage naturally indicates the direction and magnitude of change.

AI summary
A device (100) for displaying the time dependency (116) of a numerical value (114) at a driver's seat of a vehicle is described. The device (100) comprises a display (110) that shows a scale (112) of the numerical value (114). The device (100) further comprises a control unit (120) that communicates with or can be made to communicate with the display (110) for controlling the display (110). The control unit (120) detects the numerical value (114) and the time dependency (116) of the numerical value and displays the numerical value (114) on the scale (112) of the display (110). For values (115) that are greater and/or less than the numerical value (114), the time dependency (116) of the numerical value (114) is also displayed.
