Vehicle Window Glass Fluorescent Message Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicles lack an effective means to transmit the driver's intention to the outside environment, limiting the ability to convey messages beyond conventional warning sounds or lights, which may not adequately communicate the driver's intentions to pedestrians or other vehicles.
Innovation Solution
A display device and message transmission method utilizing window glass that emits visible light through excitation radiation, allowing for the display of messages such as sentences, warnings, or vehicle conditions on the glass surface, using a light source and a multilayer window glass structure with a fluorescent material to convey information to the outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional warning sounds and lights are used to transmit information, then the transmission distance and clarity of driver's intention are limited, but the device complexity increases when adding more transmission means
Solution Approach 1:
The window glass is designed to serve multiple functions: it acts as both the vehicle's windows and as a display device for transmitting messages to the outside environment. By incorporating fluorescent material into the window glass interlayer, the same glass structure can display various messages (warnings, greetings, vehicle conditions) without requiring separate display devices, thus reducing overall system complexity while improving information transmission capability
Solution Approach 2:
The invention merges the window glass structure with the display function by integrating fluorescent material into the glass interlayer. This combination allows the window glass to emit visible light when irradiated with excitation light, creating a unified structure that eliminates the need for separate display devices and improves the clarity of driver's intention transmission
2Adaptability or versatility
If window glass with fluorescent material is used to display messages, then information transmission capability is improved, but the manufacturing complexity of the window glass increases
Solution Approach 1:
The window glass is constructed as a composite material structure with fluorescent material embedded in the interlayer between glass panes. This composite approach allows the window glass to gain message display capability through the fluorescent properties of the embedded material, while the overall manufacturing process remains integrated with conventional laminated glass production methods
Solution Approach 2:
The invention utilizes changes in the optical parameters of the window glass by incorporating fluorescent material that can be excited by specific wavelengths of light. The glass can transition between non-emissive and emissive states depending on the excitation light input, enabling message display without fundamentally altering the glass manufacturing process
3Productivity
If excitation light is used to make window glass emit visible light, then message transmission efficiency is improved, but the energy consumption increases
Solution Approach 1:
The invention replaces conventional electric display systems with a photoluminescence-based system. Instead of using electrically powered LEDs or screens, the window glass utilizes fluorescent material that converts excitation light into visible light emission. This substitution reduces energy consumption by leveraging optical conversion rather than electrical illumination, while maintaining high message transmission efficiency
