Active Vehicle Suspension for Mobile Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Occupants in vehicles experience increased input errors and motion sickness due to unfavorable road conditions while using portable computing devices, which existing technologies fail to adequately address.
Innovation Solution
A system that adjusts the vehicle suspension and alerts occupants by collecting data on vehicle and user device operations, using active suspension systems and communication networks to dynamically tune the ride quality and alert the occupant as needed.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the vehicle suspension is adjusted to smooth out road irregularities, then occupant comfort is improved, but the complexity of the suspension system increases
Solution Approach 1:
The suspension system dynamically adjusts its characteristics in real-time based on detected road conditions and user device operations. The system transitions from a static suspension configuration to a dynamic one that adapts to changing conditions, allowing it to reduce motion sickness only when needed rather than requiring complex active suspension components continuously
Solution Approach 2:
The system changes suspension parameters (such as damping coefficients or spring rates) based on detected conditions. By monitoring user device operation stability and road conditions, the system modifies suspension characteristics to reduce harmful vibrations only when input errors or motion sickness are detected, rather than maintaining complex active control continuously
2Object-affected harmful factors
If the suspension system continuously monitors road conditions and user operations, then ride quality is improved, but the energy consumption increases
Solution Approach 1:
The system performs preliminary detection of road conditions and user device operations before adjusting the suspension. By monitoring conditions in advance and only activating suspension adjustments when instability is detected, the system avoids continuous energy-consuming adjustments while still preventing input errors before they occur
Solution Approach 2:
Instead of continuous monitoring and adjustment, the system periodically checks road conditions and user device operation stability. Suspension adjustments are made only when detected conditions indicate a problem, converting continuous energy consumption into periodic action that achieves the same protective effect with lower energy usage

AI summary
A user device is identified as being operated by a vehicle occupant. An operation being performed by the user device is identified. A road condition is determined. A vehicle suspension is adjusted based at least in part on the identified user device operation and the road condition.
