Vehicle Interior Illumination Device Dynamic Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle interior illumination devices primarily use monochromatic lights, resulting in a low decoration effect and failing to dynamically adjust lighting based on external scenes, interior temperatures, and vehicle speeds, which limits their ability to create an immersive and informative atmosphere.
Innovation Solution
A vehicle interior illumination device with multiple illumination parts and a control system that selects themes based on external images, interior temperatures, and vehicle speeds, using color-changing, intensity-adjusting, and flashing capabilities to create a dynamic lighting environment, including the use of optical parts to ensure lights are visible only when active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monochromatic lights are used for vehicle interior illumination, then the device structure is simple, but the decoration effect is low
Solution Approach 1:
The patent applies color-changing LEDs as the light source that can emit different colors (red, green, blue, yellow, purple, etc.) to create various decorative effects. The control unit enables these LEDs to change colors dynamically based on different modes (ambient mode, sport mode, comfort mode, etc.), thereby improving the decoration effect without significantly increasing device complexity.
Solution Approach 2:
The illumination device transitions from static monochromatic lighting to dynamic multi-color lighting that can change intensity, color, and pattern. The control unit enables dynamic adjustment of illumination parameters including color temperature (2000K-10000K), intensity (0-100%), and lighting patterns (steady, pulsing, fading), creating a dynamic and adaptable decoration system.
2Adaptability or versatility
If multiple illumination colors and dynamic control are added, then the decoration effect is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls color selection, intensity adjustment, lighting patterns, and coordinates with vehicle sensors (door sensors, speed sensors, temperature sensors). The same control unit manages both decorative lighting and functional warning signals, consolidating multiple functions into a single device to minimize overall system complexity.
Solution Approach 2:
The illumination device automatically adjusts its behavior based on vehicle conditions without requiring manual user input for each adjustment. The system self-regulates lighting parameters based on detected conditions (e.g., automatic warning flash when door is not locked, automatic color change based on vehicle speed), reducing the need for complex user interfaces and manual control mechanisms.
3Device complexity
If the light emitting part is always visible, then the structure is simple, but the impressive feeling is reduced when lights are on
Solution Approach 1:
The cover featuring the through-hole is designed to rotate periodically, creating alternating visibility of the light emitting part. During rotation, the hole periodically aligns with the LED to allow light transmission, creating a pulsing or flashing effect that enhances visual impact. This periodic motion transforms a static structure into a dynamic visual display without requiring complex additional components.
