Vehicle Seat Touchscreen Haptics With 3D Posture Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle seat adjustment methods rely on physical buttons or mechanical switches, which are not user-friendly and do not provide intuitive feedback, making it difficult for users to adjust seats safely and rationally during driving.
Innovation Solution
A haptic feedback control method and device that uses a display screen with a touch module and vibration sensor to display a 3D model of the vehicle seat, allowing users to adjust the seat's posture through touch instructions, with haptic feedback simulating the adjustments, including speed variations based on touch position, to enhance user interaction and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical buttons or mechanical switches are used for seat adjustment, then the adjustment function is reliable, but the user interaction is not intuitive and lacks feedback
Solution Approach 1:
The patent replaces physical mechanical buttons and switches with a touchscreen display interface. The display screen shows a 3D model of the seat and adjustment options, allowing users to interact through touch gestures rather than physical button presses. This substitution provides intuitive visual feedback and easier operation while maintaining adjustment reliability through the touchscreen control system.
Solution Approach 2:
The patent implements feedback by displaying a 3D model of the seat on the screen that visually represents the current seat position and adjustment options. When users touch the screen to adjust the seat, the 3D model updates to show the new position, providing immediate visual feedback. The system also provides tactile feedback through vibration or resistance when touching the screen, enhancing the interaction experience while maintaining reliable control.
2Measurement precision
If physical buttons are used for seat adjustment, then the control is simple, but the adjustment precision and user control are insufficient
Solution Approach 1:
The patent segments the seat adjustment control into multiple independent adjustment options displayed on the touchscreen. Each adjustment parameter (seat position, backrest angle, cushion angle, etc.) is represented as a separate controllable element on the 3D model or as distinct buttons. This segmentation allows precise control of each parameter independently while keeping the interface organized and manageable, avoiding overwhelming complexity.
Solution Approach 2:
The patent adds a visual dimension to the control interface by displaying a 3D model of the seat on the touchscreen. This 3D visualization provides spatial context and allows users to understand seat position and adjustment options in three dimensions rather than through abstract button labels. The 3D model can be rotated and viewed from different angles, enhancing precision while the touchscreen maintains simplicity through touch gestures.
3Ease of operation
If touchscreen control is implemented, then the user interaction becomes intuitive, but the device complexity increases
Solution Approach 1:
The patent makes the display screen serve multiple functions: it displays vehicle information, shows the 3D seat model, provides adjustment controls, and delivers tactile feedback. By making the touchscreen a universal interface that combines visualization, control, and feedback functions, the system reduces the need for separate physical controls while managing complexity through multi-functionality. The same hardware component (touchscreen) performs multiple roles, simplifying the overall device architecture despite the increased sophistication of each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method enables intuitive and rational adjustment of vehicle seats through visual and haptic feedback, improving user interaction and ensuring safe driving by replacing physical buttons with virtual controls and providing authentic tactile feedback.
Implementation Method 1
controlling the vibration sensor to perform haptics at a position of the touch adjustment button
Implementation Method 2
the display screen is provided with piezoelectric devices, and after the receiving a touch instruction, on the touch adjustment button, from a user, the method further includes: controlling the piezoelectric device to perform haptics at a position of the displayed touch adjustment button

AI summary
Provided are a haptic feedback control method, a haptic feedback control device, and a storage medium. The haptic feedback control method includes: controlling a display screen to display an adjustment information page having a touch adjustment button and a three-dimensional (3D) model of a vehicle seat upon receiving an instruction to display the page on the display screen, where the display screen has a vibration sensor; and receiving a touch instruction, on the touch adjustment button, from a user, adjusting a posture of the vehicle seat through the touch adjustment button, controlling the vibration sensor to perform haptics at a position of the touch adjustment button, and controlling the display screen to synchronously display a posture of the 3D model of the vehicle seat that is the same as that of the vehicle seat.
