Solution Overview
Problem
Conventional vehicle taillights are bulky and inefficient due to the need for separate housing and space allocation for brake, reverse, and turn signal light emitting devices, which complicates internal space management.
Innovation Solution
A vehicle taillight design featuring a main light emitting device with a housing, light guide seat, reflective seat, semi-reflective light transmitting plate, and light adjusting structure, allowing for integrated functions like driving, brake, and reverse signal lighting without the need for multiple devices, optimizing space and reducing bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate light emitting devices are used for brake, reverse, and turn signal functions, then each function can be independently controlled, but the housing becomes bulky and internal space allocation becomes complex
Solution Approach 1:
The patent combines multiple light emitting devices (brake light, reverse light, turn signal) into a single integrated housing. The housing contains multiple light emitting units that can be independently controlled to perform different functions, thereby reducing overall housing volume while maintaining functional independence.
Solution Approach 2:
The single housing serves multiple functions by accommodating different light emitting devices that can operate independently. The housing structure is designed to support brake lighting, reverse lighting, and turn signal functions within a unified body, making it a multi-functional component.
2Adaptability or versatility
If separate light emitting devices are used for brake, reverse, and turn signal functions, then each function can be independently controlled, but internal space allocation becomes complex
Solution Approach 1:
The housing is segmented into multiple compartments or zones, each dedicated to a specific light emitting device function. This segmentation allows for organized spatial arrangement of different lighting functions (brake, reverse, turn signal) within the housing, simplifying internal space allocation while maintaining functional independence.
Solution Approach 2:
The patent employs a nested arrangement where light emitting devices are positioned within the housing structure in a space-efficient manner. Some light emitting units may be positioned within or adjacent to others, optimizing the use of internal housing space while maintaining independent control capability for each function.
3Illumination intensity
If conventional light emitting devices are used, then sufficient light intensity can be achieved, but the housing becomes bulky
Solution Approach 1:
The patent utilizes thin film light transmitting plates with semi-reflective properties to achieve efficient light transmission while maintaining a compact housing structure. These thin film elements allow sufficient light intensity to pass through without requiring bulky housing components, thereby reducing overall housing volume while maintaining illumination performance.
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 design enhances light variability and visual attention with controlled light intensity and shape, achieving efficient signal effects for driving, braking, and reversing while minimizing space usage and preventing light interference.
Implementation Method 1
The light transmitting plate is made of a semi-reflective material to allow a portion of light to pass therethrough and the other portion of the light to reflect onto the reflective plate 125
Implementation Method 2
From the reflective plate 125, the light is again reflected onto the light transmitting plate 127, thereby resulting in gradual change of light
Implementation Method 3
The light guide portion is configured to transmit a portion of the first color light rearwardly to the light cover and to guide the other portion of the first color light to reflect forwardly onto the reflective plate

AI summary
A vehicle tailight includes a housing seat and a light cover cooperatively defining an accommodation space, and a main light emitting device disposed in the accommodation space and including first and second light emitting members capable of emitting first and second color lights, respectively, a reflective plate, an isolation portion corresponding to the second light emitting members, and a light transmitting plate having a light guide portion for transmitting a portion of the first color light rearwardly to the light cover and to guide the other portion thereof to reflect forwardly onto the reflective plate, which in turn, reflects the first color light rearwardly. A light adjusting structure guides the second color light to project rearwardly.
