Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light-emitting assembly is made visible to enhance interior atmosphere, then the ambiance enhancement effect is improved, but the assembly becomes noticeable when not in use, failing to maintain a discreet appearance
Solution Approach 1:
The pattern layer is divided into multiple micro-patterns (0.025-0.26mm radial size) arranged at intervals, creating a discrete structure that can be selectively illuminated. When off, the segmented micro-patterns blend into the background; when on, they create visible light patterns for ambiance enhancement.
Solution Approach 2:
The pattern layer utilizes photoluminescent micro-patterns that change from invisible/blend-in state to visible luminous state when activated. The micro-patterns emit light when excited, transforming the appearance from discreet to visually prominent, solving the contradiction between visibility when needed and discretion when not needed.
2Shape
If the pattern layer is made thick enough to be visible when off, then the aesthetic appearance is improved, but the light transmission and emission efficiency deteriorates
Solution Approach 1:
Different regions of the light-transmitting member have different properties: the pattern layer contains photoluminescent micro-patterns with specific optical characteristics, while the surrounding areas maintain high light transmission. This local differentiation allows the pattern layer to be visible when needed without compromising overall light transmission efficiency.
Solution Approach 2:
The optical parameters of the pattern layer are optimized by controlling micro-pattern size (0.025-0.26mm radial dimension) and spacing (0.2-1.5mm interval). These parameter adjustments enable the pattern layer to achieve sufficient visibility while maintaining adequate light transmission and emission efficiency.
3Illumination intensity
If micro-patterns are made large enough to be visible, then the pattern visibility is improved, but the resolution and detail of the pattern deteriorates
Solution Approach 1:
The visibility of the micro-patterns is dynamically controlled through light activation. When off, the micro-patterns remain invisible regardless of their small size. When activated, the photoluminescent properties cause the micro-patterns to emit light, making them visible without requiring large dimensions that would compromise resolution.
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 light-emitting assembly enhances the vehicle interior atmosphere by providing a visible luminous pattern layer when powered on, while maintaining a hidden appearance when off, thus addressing issues of visibility, aesthetics, and coordination with other interior lighting.
Implementation Method 1
The multiple micro-patterns are self-luminous, and the pattern layer is visible during photoluminescence of the multiple micro-patterns

AI summary
A light-emitting assembly and a vehicle are provided in the disclosure. The light-emitting assembly includes a light-transmitting member and a pattern layer. The pattern layer is attached to a surface of the light-transmitting member and includes multiple micro-patterns arranged at intervals. Each of the multiple micro-patterns has a radial size ranging from 0.025 mm to 0.26 mm, and a distance between each two adjacent micro-patterns ranges from 0.2 mm to 1.5 mm. When the light-emitting assembly is powered on, the multiple micro-patterns are configured to emit light to enable the pattern layer to be visible. The light-emitting assembly provided in the disclosure can enhance the vehicle interior atmosphere.
