Rotating Masking Cover for Multi-Symbol Vehicle Garnish Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges in implementing numerous symbols within a limited area of the garnish without compromising aesthetics, which impairs user convenience due to the lack of effective methods for illuminating and displaying various program functions.
Innovation Solution
A lighting device for vehicles featuring a masking cover with variable pattern portions that rotate to selectively illuminate different shapes, a touch sensor to detect pressure, and a fixed lighting unit with a light guide, allowing multiple symbols to be displayed in one area by adjusting the masking cover's position, enabling users to easily select programs with minimal motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple symbols are illuminated in a limited area of the garnish, then user convenience is improved, but the aesthetic feature of the garnish is impaired
Solution Approach 1:
The masking cover is designed to be rotatable, allowing dynamic reconfiguration of symbol patterns. This enables multiple different symbol arrangements to be displayed in the same limited area, improving user convenience for selecting various programs while maintaining aesthetic appeal through rotational movement rather than expanding the static display area.
Solution Approach 2:
The invention adds the rotational dimension to the garnish display system. Instead of merely expanding the two-dimensional area to fit more symbols, the masking cover rotates to present different symbol patterns sequentially, effectively utilizing the third dimension (rotation) to accommodate multiple symbols without compromising the limited garnish area's aesthetics.
2Quantity of substance
If a masking cover with variable pattern portions is rotated to display multiple symbols, then the quantity of displayable symbols is improved, but the device complexity increases
Solution Approach 1:
The masking cover integrates multiple functions into a single component: it serves as both the display surface for symbols and the rotating mechanism for switching between different symbol patterns. The variable pattern portions are directly formed on the masking cover itself, eliminating the need for separate movable symbol elements and reducing overall device complexity while still enabling multiple symbols to be displayed.
3Adaptability or versatility
If the masking cover is disposed in different positions to illuminate symbols, then the versatility of the lighting device is improved, but the ease of operation is worsened
Solution Approach 1:
The masking cover is designed to rotate through predetermined positions (first, second, and third positions) to illuminate different symbols. This periodic rotational action allows the system to cycle through multiple symbol options, providing versatility for displaying various program functions. The touch sensor enables users to easily trigger these periodic rotations without requiring complex manual positioning operations.
