Solution Overview
Problem
Current vehicle keys do not effectively connect with relevant vehicle information, lacking intuitive and efficient means to provide users with data such as vehicle position, status, and functionalities.
Innovation Solution
An augmented reality device is linked to a vehicle's key, enabling communication and display of vehicle information, including position, range, status, and functionalities through Bluetooth or other technologies, allowing interaction and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vehicle keys are made simple with minimal features, then device complexity is reduced and ease of manufacture is improved, but information provision capability and user interaction functionality deteriorate
Solution Approach 1:
The patent introduces an intermediary system consisting of a mobile device and augmented reality interface that mediates between the simple key and the vehicle. The key itself remains simple, but when brought near the vehicle, it triggers information display through the mobile device's camera and AR overlay, providing comprehensive information without complicating the key's structure
Solution Approach 2:
The patent transitions information display from the traditional two-dimensional key surface to the three-dimensional spatial environment around the user. By using the mobile device camera to capture the real-world view and overlay virtual information elements in augmented reality, the system provides information in an additional dimensional space without adding physical complexity to the key
2Adaptability or versatility
If vehicle keys integrate multiple communication technologies and features, then functionality and user interaction are improved, but device complexity increases
Solution Approach 1:
The patent makes the mobile device universal by leveraging its existing multi-functional capabilities (camera, display, processor, communication modules) to perform multiple functions: detecting the key, rendering augmented reality information, providing user interface interactions, and communicating with the vehicle. This avoids adding dedicated specialized devices for each function
Solution Approach 2:
The system enables the mobile device to self-serve by using its own built-in resources (camera for detection, display for information presentation, processor for rendering) to provide the augmented reality interface functionality, rather than requiring separate dedicated components in the key or vehicle
3Ease of operation
If vehicle information is displayed through traditional interfaces, then device complexity is minimized, but user experience and information accessibility deteriorate
Solution Approach 1:
The patent enhances user experience by moving information display from flat 2D screens to immersive 3D augmented reality space. Information elements are overlaid on the real-world view captured by the camera, allowing users to interact with vehicle information in their natural field of vision rather than requiring them to look at and interpret traditional screen interfaces
Solution Approach 2:
The patent uses visual differentiation through color and appearance variations in the augmented reality information elements to improve usability. Different vehicle components or status states are represented with distinct visual characteristics, allowing users to quickly identify and understand information without complex text or icons
