Steering Wheel Visual Indicators for Unobstructed Driver Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional dashboard display panel in vehicles is often obstructed by the steering wheel and driver's hand, making it inconvenient and potentially hazardous for the driver to view important indicators, leading to unnoticed warnings and unsafe driving conditions.
Innovation Solution
Mounting indicators directly onto, within, or adjacent to the steering wheel, using sensors to process and display vehicle operations-related information in a manner that remains visible to the driver, even during steering wheel rotation and hand position changes, ensuring unobstructed visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the dashboard display panel is placed behind the steering wheel, then the dashboard can be integrated into the steering column structure, but the view of the indicators gets obstructed by the steering wheel and driver's hand
Solution Approach 1:
The patent extracts the indicators from the traditional dashboard location behind the steering wheel and relocates them directly onto the steering wheel structure. This extraction resolves the visibility obstruction problem by placing indicators in a location that is always visible to the driver regardless of steering wheel position or hand placement.
Solution Approach 2:
The patent transitions the indicator display from a two-dimensional flat dashboard surface to a three-dimensional structure on the steering wheel itself, utilizing the radial and circumferential dimensions of the steering wheel to position indicators in optimally visible locations.
2Device complexity
If the dashboard display panel is placed behind the steering wheel, then the dashboard structure is compact, but important warnings may go unnoticed leading to safety problems
Solution Approach 1:
Critical warning indicators are extracted from the obscured dashboard area and placed directly on the steering wheel where they cannot be missed by the driver, ensuring that safety-critical information is always visible regardless of steering operations or hand position.
Solution Approach 2:
The patent utilizes color-coded indicators (red, yellow, green) to convey different levels of urgency and importance, with critical warnings displayed in prominent colors that immediately attract the driver's attention and cannot be overlooked.
3Ease of operation
If the driver must move head, steering wheel, hands or other obstruction to view indicators, then the dashboard can maintain traditional positioning, but it leads to inattentive or hazardous driving
Solution Approach 1:
The patent positions indicators at locations on the steering wheel that are within the driver's natural field of view without requiring any additional head movement or distraction from the road, creating an equipotential viewing condition where all critical information is accessible at the same visual level as the road ahead.
Data Source
AI summary
Visual indicators on a steering wheel of a vehicle provide information to a driver of the vehicle. In one embodiment an input stage is used to receive an input signal. The signal is processed to provide a signal for an indicator on the steering wheel. Conditions of the steering wheel can be sensed to provide modification of the indicator display. For example, the rotation or orientation of the steering wheel can be taken into account to modify the display for better viewing. The position or placement of a driver's hand on the steering wheel can be used to change the display of indicators so that the indicators are less obscured.
