Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing amount of information in vehicles, particularly in off-road driving situations, requires a more effective way to display the instantaneous steering angle to enhance driver safety and awareness without distracting the driver from the road.
Innovation Solution
A method and display system that generates and displays graphic objects representing the steering wheel, axis, and steering angle in a realistic and adaptable manner, using a combination of detected steering angles, camera inputs, and programmable display areas to provide real-time and easily interpretable information about the steering angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a freely programmable screen is used to display information in the instrument cluster, then the adaptability of displayed information to driver needs is improved, but the clarity and immediate comprehensibility of critical information like steering angle may deteriorate
Solution Approach 1:
The display information is segmented into different types: critical operational parameters (steering angle) are displayed using dedicated graphic objects with specific visual conventions, while other information can be displayed using programmable formats. This segmentation allows critical information to maintain immediate comprehensibility while the overall system retains adaptability.
Solution Approach 2:
Different display formats are applied to different types of information within the same display system. Critical information like steering angle uses standardized graphic objects with consistent visual properties for immediate comprehension, while other information can use adapted formats, creating local quality variations that optimize both adaptability and comprehensibility.
2Adaptability or versatility
If digital displays replace mechanical gauges in the instrument cluster, then the adaptability and information capacity are improved, but the immediate readability and intuitive understanding of vehicle status may worsen
Solution Approach 1:
The patent creates graphic objects that copy the visual appearance and behavior of traditional mechanical gauges (needles, scales, circular displays) but implements them digitally. This allows the display to maintain the immediate readability of mechanical gauges while gaining the adaptability and information capacity of digital systems.
Solution Approach 2:
The system changes the parameter of display format from purely digital to a hybrid that incorporates visual metaphors from mechanical gauges. By adjusting parameters like display shape, needle animation, and scale markings, the system maintains immediate readability while enabling digital adaptability.
3Adaptability or versatility
If comprehensive information from multiple sensors and systems is displayed, then the usefulness to the driver is improved, but the distraction from the road and cognitive load may worsen
Solution Approach 1:
The patent extracts and separates critical information (steering angle) from the general stream of information and gives it a distinct visual representation through dedicated graphic objects. This extraction allows critical information to be processed intuitively without adding to cognitive load, while other information remains available but visually differentiated.
Solution Approach 2:
Instead of presenting all information in a uniform detailed format that requires cognitive processing, the patent inverts the approach by using simplified, intuitive visual metaphors for critical parameters. This inversion reduces cognitive load while maintaining usefulness by matching the visual representation to natural driver expectations.
