Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle impact attenuators are not mobile or autonomous, failing to effectively mitigate potential collisions without human intervention, as they are typically stationary and cannot adapt to changing collision risks or redirect vehicles to prevent accidents.
Innovation Solution
An autonomous mobile attenuator system that deploys mobile impact attenuators to predicted locations based on collision risk assessments from sensors, using patterns like triangular or linear configurations to dissipate kinetic energy and potentially redirect errant vehicles, equipped with processors for real-time risk analysis and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stationary impact attenuators are used, then kinetic energy can be dissipated through sand scattering, but the system cannot adapt to changing collision risks or move to predicted locations
Solution Approach 1:
The impact attenuator is transformed from a stationary to a mobile system by equipping it with a vehicle platform, propulsion system, and positioning components. This allows the attenuator to dynamically relocate to predicted collision locations based on real-time risk assessment from sensor data, resolving the contradiction between adaptability and complexity by making the system mobile rather than fixed
Solution Approach 2:
The system performs autonomous operation where the processor independently analyzes sensor data, determines collision risk, selects optimal deployment locations, and controls the mobile attenuator's movement without human intervention. This self-service capability enables the system to adapt to changing conditions automatically while maintaining manageable complexity through automation
2Extent of automation
If mobile attenuators are deployed autonomously, then the system can respond to dynamic collision risks, but the extent of automation increases system complexity
Solution Approach 1:
The mobile attenuator platform integrates multiple functions into a single system: sensor data acquisition, collision risk analysis, location prediction, navigation, and impact attenuation. This multi-functionality reduces overall system complexity by consolidating what would otherwise require separate systems, while enabling high程度的 automation through unified control architecture
Solution Approach 2:
The system implements closed-loop feedback where sensors continuously monitor the environment, the processor analyzes data and adjusts the attenuator's position and deployment strategy in real-time based on changing collision risks. This feedback mechanism enables autonomous operation by allowing the system to self-correct and adapt without human intervention, managing complexity through intelligent control
3Ease of operation
If sand-filled barrels are used to dissipate kinetic energy, then vehicle deceleration is smoothed, but the attenuators cannot redirect vehicles or respond to errant vehicles in real-time
Solution Approach 1:
The attenuator system uses mobile positioning mechanisms including steerable wheels or tracks to dynamically redirect errant vehicles by adjusting its orientation and position in response to real-time sensor data. This dynamic redirection capability replaces static sand-barrel arrangements, enabling active vehicle guidance while managing complexity through standardized mobile platform components
Solution Approach 2:
The system performs preliminary deployment by positioning the mobile attenuator at predicted collision locations before actual impact occurs. Sensors detect potential errant vehicles, the processor calculates optimal interception points, and the attenuator relocates in advance to prepare for energy dissipation or vehicle redirection, enabling proactive safety intervention rather than reactive response

Function Achieved in This Case
The system effectively mitigates potential vehicle collisions by deploying mobile attenuators to high-risk areas, reducing the risk of injury by dissipating kinetic energy and potentially redirecting vehicles, thereby enhancing safety in dynamic collision scenarios.
Implementation Method 1
when a vehicle collides with the barrels they shatter, the kinetic energy of the vehicle is dissipated by scattering the sand, and the vehicle decelerates smoothly
