Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assist systems and dummy bumpers are inadequate in determining and selecting the best option to protect vehicle occupants and collision-involved objects, as they focus on avoiding collisions from a self-centered perspective and are not capable of handling unexpected or unavoidable collisions effectively.
Innovation Solution
A cognitive collision detection system that predicts collision situations using multiple data inputs, determines the optimal smart bumper system configuration, and deploys appropriate options such as mechanical, electromagnetic, or pneumatic bumpers to minimize damage, with the ability to communicate with other vehicles to coordinate collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional driver assist systems and dummy bumpers are used, then the system structure is simple, but the system cannot effectively determine and select the best option to protect vehicle occupants during unavoidable collisions
Solution Approach 1:
The bumper system transitions from a static dummy bumper to a dynamic smart bumper that can change its properties in real-time. The cognitive collision detection system continuously monitors traffic data and dynamically determines the optimal bumper configuration (mechanical, electromagnetic, or pneumatic) based on the specific collision scenario, allowing the system to adapt its protection strategy rather than relying on a fixed structure
Solution Approach 2:
The smart bumper system integrates multiple bumper types (mechanical, electromagnetic, and pneumatic) into a single universal system that can perform different protection functions. The cognitive collision detection system selects the most appropriate bumper type for each specific collision scenario, making the system multi-functional and capable of handling various collision situations effectively
2Reliability
If the cognitive collision detection system analyzes multiple data inputs and coordinates with other vehicles, then the collision protection effectiveness is improved, but the system complexity and communication requirements increase
Solution Approach 1:
The cognitive collision detection system performs preliminary analysis of traffic data from multiple sensors and communicates with other vehicles' detection systems before the collision occurs. By predicting the collision in advance and determining the optimal bumper configuration beforehand, the system reduces the complexity of real-time decision-making during the actual collision event
Solution Approach 2:
The cognitive collision detection system acts as an intermediary between multiple data sources (sensors, communication systems) and the smart bumper system. It processes and integrates information from various inputs, coordinates with other vehicles' detection systems, and translates this complex information into specific control commands for the bumper system, simplifying the overall system architecture
3Adaptability or versatility
If the smart bumper system deploys multiple bumper types (mechanical, electromagnetic, pneumatic), then the adaptability to different collision scenarios is improved, but the device complexity increases
Solution Approach 1:
The smart bumper system uses dynamic control to switch between different bumper types (mechanical, electromagnetic, pneumatic) based on the specific collision scenario. The cognitive collision detection system determines the optimal bumper configuration in real-time and activates only the necessary bumper type, allowing the system to be adaptable without requiring all bumper components to be simultaneously active
Solution Approach 2:
The system changes the operational parameters of the bumper system by selecting different bumper types for different collision scenarios. The cognitive collision detection system adjusts parameters such as bumper stiffness, activation timing, and deployment force based on the predicted collision characteristics, enabling adaptability through parameter variation rather than structural complexity
