Bicycle Radar Sensor System for Cyclist Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclists often have limited visibility of their surroundings, particularly behind them and beyond turns, making it difficult to detect nearby targets such as moving vehicles, obstacles, pedestrians, or other cyclists, relying heavily on natural senses for awareness.
Innovation Solution
A radar sensor system that includes a radar sensor housing and a mobile electronic device, providing situational awareness indicators through a display, audible feedback, and haptic alerts, informing cyclists of targets in proximity, including location, distance, and direction, using radar sensor data to enhance awareness while riding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cyclists rely on natural senses to detect approaching vehicles and obstacles, then the system remains simple and requires no additional equipment, but the cyclist's awareness of surrounding targets is insufficient and limited
Solution Approach 1:
The patent introduces radar sensors as an intermediary device that detects targets (vehicles, obstacles, cyclists) and transmits this information to the cyclist through a mobile electronic device. This mediator bridges the gap between the cyclist's limited natural senses and the need for comprehensive situational awareness, resolving the contradiction by providing reliable target detection without requiring the cyclist to directly perceive all hazards
2Loss of information
If multiple sensors and processing components are added to improve target detection, then situational awareness is enhanced, but the device complexity increases
Solution Approach 1:
The patent employs a mobile electronic device that performs multiple functions: it receives radar sensor data, processes target information, displays situational awareness indicators, and provides navigation guidance. By using a single multi-functional device rather than separate specialized components for each function, the system reduces overall complexity while still achieving comprehensive target information processing and presentation
3Reliability
If the radar sensor system provides comprehensive situational awareness information, then cyclist safety is improved, but the processing requirements and energy consumption increase
Solution Approach 1:
The system processes radar data to identify and prioritize significant targets (vehicles, obstacles, cyclists) rather than attempting to process and display all detected objects with equal detail. The mobile electronic device selectively presents situational awareness information based on target relevance and cyclist needs, reducing the overall processing burden and energy consumption while maintaining safety-critical awareness of important surrounding targets

AI summary
A radar sensor system implemented using a radar sensor housing and a module electronic device configured to present situational awareness indicators associated with targets determined to be located in proximity to a bicycle. The mobile electronic device includes a position-determining component for determining a current geographic position of the bicycle, a wireless transceiver for receiving radar sensor data from a radar sensor in the radar sensor housing, a display, and a processor coupled with the position-determining component, the wireless transceiver, and the display. The processor is configured to determine one or more situational awareness indicators based on the received radar sensor data and cause the display to present location information and the one or more situational awareness indicators.
