Rear View Mirror Indicator Structure for Concentrated Low-Glare Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear view mirror direction flash indicators emit flash signals that diverge excessively, leading to poor prompting effectiveness due to lack of concentration and potential glare.
Innovation Solution
A vehicle rear view mirror indicator featuring a mirror, light-emitting device, first and second light-shielding plates, and a grid-shaped transparent part, where the light-emitting device is aligned with the transparent part through the plates to concentrate and soften the light emission, preventing excessive divergence and glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the flash signal is directly emitted from the light-transmitting part, then the structure is simple, but the light diverges excessively and the prompting effect is poor
Solution Approach 1:
The patent introduces a light-reflecting plate as an intermediary component between the light-emitting device and the light-transmitting part. This reflective plate redirects the light path, causing light to first hit the reflective surface and then transmit through the transmitting part, thereby concentrating the light output and improving the prompting effect without significantly complicating the overall structure.
2Device complexity
If the flash signal is directly emitted from the light-transmitting part, then the structure is simple, but the light spreads around and is not concentrated enough
Solution Approach 1:
The light-reflecting plate serves as a mediator that controls light direction by reflecting light at specific angles. This allows the light to be directed more precisely through the light-transmitting part, improving manufacturability and light direction control while maintaining relatively simple construction.
3Device complexity
If the light is emitted without shielding plates, then the structure is simple, but the light causes excessive glare and discomfort
Solution Approach 1:
The light-reflecting plate acts as an intermediary that modifies the light path to reduce direct glare. By reflecting light at controlled angles rather than allowing direct emission, the plate softens the light output and reduces harmful glare effects on surrounding areas while maintaining the indicator's visibility function.
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 solution effectively concentrates light emission, enhancing the prompting effect for vehicles and pedestrians while minimizing discomfort from glare, ensuring the flash signal is clearly visible without excessive spread.
Implementation Method 1
a light-emitting device is arranged between the outer cover and the mirror. The mirror is in a position opposite to the light-emitting device. A light-transmitting part is provided, and the light-emitting device is used to emit alternating light and dark flash signals
Implementation Method 2
utilizes the cooperation of the first light-shielding plate, the second light-shielding plate, and the grid-shaped transparent part to help the light emitted by the light-emitting part concentrated but relatively soft, without causing excessive glare and discomfort
