Bicycle Display With Radar Alerts for Rearward Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles, particularly those with electric drives, pose a risk in traffic due to the inability of riders to timely detect rearward road users, and existing rear view mirrors are prone to damage and discomfort.
Innovation Solution
A display device with electrically controllable luminous elements mounted on the handlebar or helmet, integrated with a radar sensor to alert riders to potential hazards in the rearward region through light patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rear view mirror is mounted on the handlebar to monitor the rearward region, then the rider can continuously monitor the rearward region without turning the head, but the rear view mirror is particularly susceptible to being damaged and uncomfortable in handling
Solution Approach 1:
The patent replaces the mechanical rear view mirror system with an electronic display device that receives signals from radar sensors. Instead of using a physical mirror that can be damaged and is uncomfortable to handle, the system uses electronic components (display device, radar sensors, control unit) to detect and show rearward traffic situations, thereby eliminating the mechanical mirror's vulnerabilities while maintaining reliable rear view monitoring
Solution Approach 2:
The patent introduces a radar sensor and control unit as intermediaries between the rearward region and the rider. The radar sensors detect objects in the rearward region, the control unit processes this information, and the display device presents it to the rider. This intermediary electronic system replaces the direct optical reflection of a mirror, providing more reliable and damage-resistant monitoring
2Loss of information
If the rider turns the head backwards to detect rearward road users, then the rider can directly observe the rearward region, but the rider cannot concentrate on what is in front of the bicycle
Solution Approach 1:
The radar sensors continuously and preliminarily detect road users in the rearward region before the rider needs to check. The system is already monitoring the rearward area, so when a hazard is detected, the display device can immediately alert the rider without requiring the rider to turn their head for routine checks, thus maintaining forward concentration while ensuring rearward awareness
Solution Approach 2:
The patent implements a feedback system where radar sensors continuously monitor the rearward region and provide information to the display device, which then presents this information to the rider. This closed-loop feedback allows the rider to obtain rearward awareness information without breaking forward concentration, as the system automatically detects and presents relevant hazards
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances rider awareness of rearward traffic situations without requiring head turns, reducing accident risk and improving road safety.
Implementation Method 1
By interaction of the display devices according to the invention with a suitable radar sensor which monitors the rearward region of the bicycle it is thereby possible to draw the attention of the user or rider of the bicycle to road users present in the rearward region
Implementation Method 2
A display device with electrically controllable luminous elements mounted on the handlebar or helmet, integrated with a radar sensor to alert riders to potential hazards in the rearward region through light patterns
