Particular Environment Based Services TRIZ Cases
- Train Sensor Mesh for Continuous Brake Component Determination
Wireless sensor nodes and a railcar mesh network replace manual train checks, speeding brake component determination and reducing downtime.
- Wireless Reception Timing Control for Low-Power Signal Waiting
Reception waiting time is adjusted from acquired communication information to cut wireless standby power without missing signals.
- Autonomous Vehicle FOTA Failover Using Redundant Network Paths
Redundant network paths and backup firmware versions cut autonomous vehicle FOTA failures and support safe rollback after update errors.
- Vehicle Contextual Alerts for Location-Based Device Actions
Automatic detection of external devices and contextual events lets vehicles trigger location-based actions or alerts without manual setup.
- Antenna Switching in PaaK Readers for Secure Vehicle Access
Antenna switching and angle-of-arrival monitoring help PaaK readers extend access range while resisting eavesdropping and replay attacks.
- Digital Vehicle Key Sensing for Low-Operation Vehicle Access
By using mobile terminal position, quantity, and trajectory data, the vehicle enables low-operation access while preserving authentication security.
- Digital Vehicle Key Authentication With Dual Security Checks
Dual authentication combines basic key verification with position, trajectory, or identity checks to block unauthorized vehicle access after phone loss.
- Sub-Trajectory Segmentation for Mobility Data Anonymization
Splitting trajectories at visibility-based changing points adds privacy gaps while preserving mobility data utility against background knowledge attacks.
- Vehicle Network Intrusion Detection via Cyclic Message Anomalies
Thresholds on cyclic message counts and response patterns flag vehicle network intrusions in real time without broadening system complexity.
- Retractable Truck Cab Footholds for AV Hijacking Prevention
A remote oversight system retracts truck cab footholds when hijacking risk is detected, helping autonomous trucks stay secure and lawful.
- Vehicle-Attached Resource Detection for Dynamic Safety Zones
A vehicle links to attached items and carried objects to detect sensors or batteries, then adjusts safety zones and resource use.
- Bidirectional Redundancy Power Conversion for Communication Faults
A bidirectional 12V/24V converter detects communication faults and low-voltage drops, then switches supply paths to keep vehicle loads powered.
- Connected Vehicle Intersection Passing Using Shared Position Data
Shared vehicle position data enables faster intersection pass decisions, reducing safety check time and collision risk in queued traffic.
- V2X Stop Control for Adaptive Idle Stop and Regenerative Braking
Real-time V2X traffic data adapts idle stop and regenerative braking to cut fuel use, jerk, and powertrain wear during deceleration.
- Connected Vehicle Control Using Multi-Timestep Input Coordination
Projected control inputs shared across future timesteps let connected vehicles coordinate speed changes and reduce phantom traffic jams.
- Vehicle Geofence Warning with Dynamic Monitoring Periods
Dynamic monitoring periods based on vehicle speed and distance help geofence alarms catch entry into the next dangerous area in time.
- Powered Dolly Selection for Mission-Matched Vehicle Combinations
Wireless control evaluates mission and dolly operating data to locate the best powered dolly for efficient vehicle combination forming.
- Cabin Notification Control for Remote Vehicle Passenger Anxiety
Tailored cabin notifications use passenger traits and boarding position to reduce anxiety during remote vehicle travel events.
- Sensor Data Reporting Periods for Efficient Autonomous Driving Links
Different sensor data are sent on separate reporting periods to cut redundant transmissions and improve link resource use in autonomous driving.
- Selective Data Exchange Risk Evaluation for V2V and V2I Integrity
Attack-path ratings and a shared risk function gate V2V and V2I data use to limit manipulation and unauthorized access.
- Vehicle Battery Recharge Wake-Up Control for Sleep Power Saving
Stored high-voltage battery SOC lets the vehicle stay asleep until low-voltage recharging is truly needed, reducing battery drain.
