Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital side-view mirror systems struggle with accurately conveying spatial depth and size of vehicle surroundings, making it difficult to perceive the speed of following vehicles, detect obstacles in blind spots, and recognize distance to vehicles during lane changes, and they cause discomfort glare and visual disturbances during night driving.
Innovation Solution
A vehicle side-view mirror system incorporating a side-view camera, a display assembly with a lamp module and a display module, and an input mechanism, which uses LED strips to indicate distances and display guide lines, along with a blind-spot collision warning image, and an infrared camera to adjust display brightness based on driver gaze, providing real-time visual cues and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 2D display is used to show surrounding vehicles, then the display can be implemented with simple hardware, but the driver cannot accurately perceive spatial depth and distance
Solution Approach 1:
The patent transitions from 2D display to 3D holographic display, adding the depth dimension to enable accurate spatial perception. The holographic display unit generates three-dimensional images that preserve depth information, allowing drivers to perceive actual distances and sizes of surrounding vehicles without increasing horizontal or vertical display dimensions.
Solution Approach 2:
The patent introduces a light field converter as an intermediary component between the display and the driver's eye. This converter transforms conventional light into light fields that carry depth and spatial information, enabling the display of three-dimensional images that accurately represent the spatial relationships of surrounding vehicles.
2Illumination intensity
If the display brightness is increased to improve visibility, then the driver can see better in low light conditions, but glare and visual disturbance occur during night driving
Solution Approach 1:
The patent applies different brightness characteristics to different parts of the display system. The holographic display unit provides high brightness for the three-dimensional image to ensure visibility, while the ambient light sensor and controller adjust local brightness levels based on environmental conditions, preventing excessive glare during night driving.
Solution Approach 2:
The patent implements a feedback mechanism using an ambient light sensor that continuously monitors environmental light conditions and adjusts display brightness accordingly. During night driving, the sensor detects low ambient light and reduces display brightness to appropriate levels, preventing glare while maintaining sufficient visibility.
3Ease of operation
If the BCW image is displayed on a small display, then the system structure remains compact, but the driver cannot easily recognize the warning image
Solution Approach 1:
The patent uses three-dimensional holographic imaging to display BCW warnings. The 3D nature of the holographic display allows warning images to be projected into space, making them more prominent and easier to recognize without requiring a larger physical display area. The depth dimension enhances the visibility and attention-grabbing capability of warning signals.
