Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems face challenges in providing effective driving assistance using visual information, as they often require larger display devices or more complex information processing to ensure safe and efficient driving.
Innovation Solution
An information processing device and method that superimposes visual assistance information within a driver's visual field or on surrounding images, utilizing sensing results, external information, and onboard data to enhance driving assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual information for driving assistance is displayed using traditional display devices, then the driver can receive assistance information, but the display device occupies significant space and reduces the driver's visual field
Solution Approach 1:
The patent transitions from traditional 2D display surfaces to 3D spatial projection by superimposing visual information within the driver's visual field through the windshield or dashboard. This dimensional change allows assistance information to be presented without occupying physical display space, resolving the contradiction between information delivery and display device area.
Solution Approach 2:
The windshield or dashboard serves as an intermediary medium that allows visual information to be projected and displayed. Instead of using a traditional display device that occupies space, the patent utilizes the existing windshield or dashboard as a transparent or semi-transparent display surface, enabling information presentation without adding significant display device area.
2Ease of operation
If driving assistance information is displayed within the driver's visual field, then the driver can focus on the road, but the visual information may reduce the driver's awareness of surrounding environments
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics for different regions. The visual information is superimposed in specific areas of the driver's visual field (such as the lower portion or periphery) rather than uniformly across the entire field of view. This localized approach maintains driver focus on the road while preserving awareness of surrounding environments in other visual regions.
Solution Approach 2:
By projecting visual information in three-dimensional space within the driver's visual field rather than on a two-dimensional display surface, the patent creates depth perception that allows the driver to maintain spatial awareness. The 3D projection enables information to be presented at different depths and positions, preserving the driver's natural perception of surrounding environments while delivering assistance information.
3Loss of information
If larger-sized display devices are equipped to provide comprehensive driving assistance, then more information can be displayed, but the device complexity and space requirements increase
Solution Approach 1:
The patent makes the windshield or dashboard a multi-functional component that serves both as a structural element of the vehicle and as a display surface for driving assistance information. This universal approach eliminates the need for separate dedicated display devices, reducing overall system complexity while enabling comprehensive information presentation through the existing vehicle structure.
Solution Approach 2:
The windshield or dashboard acts as an intermediary that integrates multiple functions: it remains a structural component of the vehicle while simultaneously serving as a display medium. This intermediary approach allows comprehensive driving assistance information to be presented without requiring additional dedicated display devices, thereby reducing device complexity and space requirements.
