Vehicle Message Display with Solar Power and Facial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices for vehicles, such as turn signals and brake lights, fail to effectively manage 'road rage' incidents due to drivers' erratic reactions, leading to safety concerns on crowded highways.
Innovation Solution
A message display apparatus that secures to a vehicle, featuring a communication unit, processor, display portion, and power managing unit, including a solar-powered thin-film panel for energy generation, allowing for the transmission of simple messages like emojis, animations, or text, and facial/gesture recognition to enhance driver communication and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simple intervehicular communication devices like turn signals and brake lights are used, then the device complexity is low, but the communication effectiveness and road safety improvement are insufficient due to drivers' erratic reactions
Solution Approach 1:
The patent introduces an intermediary communication system that displays messages on the rear windshield or through projection films, mediating between drivers to convey intentions and emotions without direct confrontation. This intermediary display layer reduces erratic reactions by providing a controlled communication channel, improving road safety while maintaining relatively simple device complexity.
2Reliability
If enhanced communication capabilities are added to improve driver psychological state, then the communication effectiveness improves, but the device complexity and distraction risk increase
Solution Approach 1:
The display apparatus is designed to perform multiple functions: displaying text messages, emojis, animations, and projection films; detecting driver facial expressions and gestures; and providing power management through solar panels. By consolidating these diverse communication and detection functions into a single multi-functional device, the patent improves communication effectiveness while managing device complexity through integration rather than proliferation of separate components.
3Use of energy by moving object
If solar-powered thin-film panels are added for energy generation, then the energy self-sufficiency improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs thin-film solar panels that can be integrated into the display apparatus structure. These flexible thin-film panels generate electrical energy from sunlight to power the display system, improving energy self-sufficiency. The thin-film technology allows for easier integration compared to rigid solar panels, though manufacturing complexity remains a consideration that is managed through modern thin-film fabrication techniques.
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 apparatus reduces road rage by enabling enhanced communication between drivers, improving psychological states and safety through the display of messages and recognition of drivers' moods, thereby reducing accidents and enhancing overall traffic safety without distracting the drivers.
Implementation Method 1
a power generating unit to be positioned to overlap with the displaying layer

AI summary
A display apparatus configured to receive a command, and convert the command to displayable information to an outside pedestrian or drivers in other vehicles may include a main body that includes a securing portion to secure the display apparatus to a vehicle; a communication unit to receive the command; a processor to convert the command to displayable information; a display portion having a displaying layer to display information; and a power managing unit to store and provide electrical energy for the display apparatus. In one embodiment, the power managing unit may include a power generating unit to be positioned to overlap with the displaying layer.
