Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle user interfaces lack effective user-dependent differentiation and secure access control, allowing unauthorized users to access and control vehicle features without proper authentication or authorization.
Innovation Solution
A method utilizing a deformable touch-sensitive display device that acquires user input to determine user-related information, outputting an actuation signal to physically deform the display, providing user feedback and controlling access levels through adaptive 3D touchscreen technology, incorporating identification, authentication, and authorization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used as a user interface without additional authentication mechanisms, then the ease of operation is improved, but the security and access control are worsened
Solution Approach 1:
The patent introduces an intermediary authentication system that mediates between the user and the vehicle controls. This system uses biometric sensors (fingerprint, facial recognition, iris scanning) as intermediaries to verify user identity before granting access to vehicle functions, thereby maintaining ease of operation while significantly improving security.
Solution Approach 2:
The authentication system operates autonomously by automatically capturing biometric data, comparing it against stored profiles, and granting or denying access without requiring manual intervention. The system self-identifies the user and self-regulates access permissions, eliminating the need for traditional keys or passwords while maintaining security.
2Ease of operation
If the same vehicle controls are provided to all users regardless of identity, then the ease of operation is improved, but the adaptability to different user needs is worsened
Solution Approach 1:
The patent applies local quality by customizing specific vehicle functions and interfaces based on the identified user's profile. Different users receive tailored configurations for climate control, media preferences, driving modes, and navigation settings, allowing each user to interact with the vehicle according to their personal preferences while maintaining a consistent overall user experience.
Solution Approach 2:
The user interface dynamically adapts its configuration based on the authenticated user's identity. The system automatically reconfigures display settings, control availability, and vehicle parameters in real-time according to the user profile, enabling seamless transitions between different user modes without requiring manual reconfiguration.
3Loss of information
If physical deformation of the display device is used to indicate access levels, then the user feedback is improved, but the device complexity is worsened
Solution Approach 1:
The patent employs color changes in the display interface to visually indicate different access levels and authentication states. The display transitions between different colors or color intensities to communicate system status, permission levels, and interaction possibilities to the user, providing intuitive feedback without requiring complex physical mechanisms.
Solution Approach 2:
The patent introduces a third dimension of interaction by enabling the display surface to physically deform or change its topography in response to user input and authentication state. This dimensional change provides tactile feedback and visual depth variation to indicate different access levels, enhancing user feedback while maintaining a relatively simple overall device architecture.

AI summary
A method operates a user interface with a deformable touch sensitive display device for a vehicle. The method includes acquiring user input and determining user-related information based on the user input. The method also includes outputting, based on the user-related information, an actuation signal to conditionally drive an actuation device to physically deform the display device to transition from a first display state into a second display state that is different from the first display state.
