Vehicle Door Handle Display for Personalized Greeting and Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door handles lack the ability to provide comprehensive individualization options for customers, as they are limited in their display capabilities and cannot adapt to user preferences or detect approaching individuals to provide personalized greetings.
Innovation Solution
A vehicle door handle with a display element comprising a plurality of individually controllable pixels, controlled via a user interface, allowing for high-resolution visualization of graphical patterns, texts, and colors, which can be customized based on user preferences, including time, location, and weather-dependent variables, and detected via sensors or a mobile terminal application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If discrete display elements (e.g., three LEDs) are used to indicate door handle status, then the device complexity is low and ease of manufacture is high, but the resolution and visualization capability are insufficient for comprehensive individualization
Solution Approach 1:
The display element is segmented into multiple individually controllable pixels arranged in a matrix, allowing each pixel to be controlled independently to achieve high-resolution visualization of graphical patterns, texts, and colors on the door handle surface
Solution Approach 2:
The display element is seamlessly integrated into the two-dimensional surface of the door handle, creating a flat panel display that maintains the exterior surface continuity while adding visualization capability without protruding elements
2Adaptability or versatility
If a display element with multiple controllable pixels is integrated into the door handle surface, then the individualization options and visualization capability are significantly improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The display element serves multiple functions: it can display various colors, graphical patterns, texts, and color gradients, and can be controlled through different user interfaces including sensors that detect approach and mobile terminal applications, making it a universal communication interface for the vehicle
Solution Approach 2:
The display element can reproduce various visual patterns including chrome trim appearances, wood grain patterns matching the vehicle interior, carbon fiber patterns, and other decorative designs, allowing the door handle to visually match different interior themes
3Adaptability or versatility
If sensors and user interfaces are added to detect approaching users and provide personalized greetings, then the adaptability and user experience are enhanced, but the device complexity and energy consumption increase
Solution Approach 1:
The display element operates periodically based on detected user approach rather than continuously, activating only when sensors detect a user approaching the vehicle, thereby reducing overall energy consumption while maintaining personalized greeting functionality
Solution Approach 2:
The system uses sensors to detect user approach and provides feedback through the display element by showing personalized greetings and information, creating a closed-loop interaction that enhances adaptability while optimizing energy use through event-driven operation
