Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack effective means to support safe getting on and off, particularly for vulnerable individuals, and to provide necessary information to surrounding vehicles and road users, as the mobility landscape evolves towards shared and purpose-built vehicles.
Innovation Solution
A vehicle safety support system incorporating sensors, projectors, and displays to identify and track objects around the vehicle, projecting guide images and providing assistive information to ensure safe entry and exit, while also offering real-time updates and alerts to surrounding users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projector is used to project guide images on the bottom surface to assist safe getting on and off, then the safety of individuals is improved, but the device complexity increases
Solution Approach 1:
The system divides the safety support function into multiple components: sensors for detection, processors for analysis, and projectors for visual guidance. Each component handles a specific aspect of the safety function, making the overall system more manageable and effective
Solution Approach 2:
The projector acts as an intermediary between the vehicle system and individuals getting on/off. It provides visual guidance information on the ground surface, mediating the interaction between the vehicle and users to enhance safety
2Measurement precision
If sensors continuously track object movement in real time, then the measurement precision of object location is improved, but the use of energy increases
Solution Approach 1:
The sensor system performs periodic detection of object locations rather than continuous monitoring. The processor determines whether objects have moved between detection cycles and updates guidance information accordingly, reducing energy consumption while maintaining adequate tracking precision
Solution Approach 2:
The system uses the existing sensor infrastructure and processing capabilities of the vehicle to perform object detection and tracking, leveraging available resources rather than adding dedicated continuous monitoring systems
3Reliability
If the projector adjusts projection location to track moving objects, then the reliability of safety guidance is improved, but the device complexity increases
Solution Approach 1:
The system establishes a feedback loop where sensors continuously detect object positions, the processor analyzes movement, and the projector adjusts its projection location accordingly. This closed-loop control ensures the guidance information remains aligned with moving objects, enhancing safety reliability
Solution Approach 2:
The projection system serves multiple functions: displaying guidance information for stationary objects, tracking and following moving objects, and providing general safety information. This multi-functionality justifies the added complexity by consolidating multiple safety features into a single system
4Loss of information
If multiple display devices are used to provide information to surrounding vehicles and road users, then the loss of information is reduced, but the device complexity increases
Solution Approach 1:
The information display function is segmented across multiple devices: projectors for ground-level guidance, external displays for side information, and rear displays for trailing vehicle information. Each device targets a specific audience and provides relevant information, reducing overall information loss
Solution Approach 2:
The system distributes information across multiple spatial dimensions and viewing angles. Projectors provide information on the ground surface, external displays provide side views, and rear displays provide rearward information, ensuring comprehensive coverage for different road users and vehicles
