Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle touch devices lack adaptive haptic and force touch adjustments based on road conditions, leading to suboptimal user experience due to inconsistent feedback and interaction requirements.
Innovation Solution
A system that automatically adjusts haptic feedback intensity and force touch parameters, such as minimum force requirement and touch time duration, based on real-time road condition data obtained from vehicle sensors and external sources, using a touch device management unit to enhance user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic feedback and force touch parameters are kept fixed, then device complexity is reduced, but user experience deteriorates under varying road conditions
Solution Approach 1:
The system automatically adjusts haptic feedback and force touch parameters based on road condition detection without requiring manual user intervention. The touch device management unit autonomously monitors road conditions through vehicle sensors and modifies touch parameters accordingly, allowing the system to self-adapt to varying environmental conditions while maintaining optimal user experience
Solution Approach 2:
The patent implements dynamic adjustment of touch parameters (such as force thresholds, response sensitivity, and haptic feedback intensity) based on real-time road condition data. The system transitions from static fixed parameters to dynamic adaptive parameters that continuously adjust according to detected road conditions, enabling the touch interface to optimize performance for both smooth and bumpy road scenarios
2Adaptability or versatility
If manual adjustment of haptic settings is required, then adaptability to different conditions is improved, but ease of operation deteriorates due to frequent user intervention
Solution Approach 1:
The system automatically adjusts haptic feedback and force touch parameters based on road condition detection without requiring manual user intervention. The touch device management unit autonomously monitors road conditions through vehicle sensors and modifies touch parameters accordingly, allowing the system to self-adapt to varying environmental conditions while maintaining optimal user experience
Solution Approach 2:
The system implements a closed-loop feedback mechanism where road condition data from vehicle sensors is continuously fed to the touch device management unit, which then adjusts touch parameters in response. This automatic feedback loop eliminates the need for manual user adjustment while maintaining adaptability to changing environmental conditions, as the system self-regulates based on real-time road condition information

AI summary
A vehicle having a touch device configured to receive user inputs is disclosed. The touch device may include a haptic component configured to provide haptic feedback to a user and a force touch component configured to detect force applied by the user on the touch device and actuate the touch device. The vehicle may further include a transceiver and a processor. The transceiver may be configured to receive road information on which the vehicle may be traversing. The processor may be configured to obtain the road information from the transceiver, determine road condition based on the road information, and adjust parameters associated with the haptic component or the force touch component based on the road condition.
