Rotating Display Unit Reduces Following Vehicle Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle-mounted electronic devices are difficult to see due to sunlight and do not account for illumination from following vehicles, leading to prolonged visibility issues at night.
Innovation Solution
A vehicle-mounted electronic device with a main body case attached to a vehicle's ceiling, a display unit that opens and closes, and a control unit connected to a sensor that detects illumination from following vehicles, allowing the display unit to rotate and reduce glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit is attached to the ceiling surface to be openable downward, then the device structure is simplified and ease of operation is improved, but the display unit becomes extremely difficult to see due to illumination from following vehicles at night
Solution Approach 1:
The display unit is made rotatable about the vertical axis rather than being fixed in a single downward-facing position. This dynamic adjustment allows the display orientation to change based on external lighting conditions, specifically rotating away from following vehicle illumination at night while maintaining optimal viewing角度 during daytime
Solution Approach 2:
The system changes the orientation parameter of the display unit based on detection of illumination conditions. When a following vehicle's illumination is detected, the display rotates to a different angular position, thereby changing how the light interacts with the display surface and reducing glare for viewers
2Object-affected harmful factors
If the display unit is fixed in a downward position, then the device structure is simpler, but the display becomes difficult to see due to sunlight during daytime
Solution Approach 1:
The display unit serves multiple functions: it can be positioned to face downward for general use, rotated away from following vehicles at night, and potentially adjusted to face forward or sideways during daytime to avoid sunlight. This multi-position capability allows a single display unit to handle various lighting conditions and viewing scenarios
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces the impact of illumination from following vehicles, enhancing the viewing environment by minimizing glare and improving visibility for passengers.
Implementation Method 1
the display unit extremely easily receives the influence by the illumination of a following vehicle

AI summary
A vehicle-mounted electronic device according to the present invention is provided with a sensor 15 that detects illumination 17 from a following vehicle 16, in at least one of a display unit 9 and a main body case 7, and is configured such that a control unit 11 rotates the display unit 9 by means of a drive unit 10 when the sensor 15 detects the illumination 17 from the following vehicle 16. Thereby, the illumination 17 from the following vehicle 16 does not reflect on the display unit 9 toward a viewer, as a result of which, the influence by illumination from the following vehicle 16 can be reduced.
