Bicycle Saddle Radar for Rear Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders of bicycles face safety challenges due to limited awareness of conditions behind and around them, especially at night or in low-light environments, leading to potential accidents.
Innovation Solution
Integration of a radar device with left and right object detection components and warning lights into a bicycle saddle, allowing for real-time detection and warning of nearby objects, enhancing situational awareness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional warning lights are used on bicycles, then riders can see light source changes, but riders still cannot detect objects behind or beside the bicycle
Solution Approach 1:
The patent replaces traditional mechanical/optical warning lights with a radar-based detection system that uses electromagnetic waves to detect objects. The radar device emits electromagnetic waves and receives reflected signals to identify objects behind and beside the bicycle, providing information that light sources alone cannot convey about object position and movement.
Solution Approach 2:
The patent introduces an intermediary radar detection system between the rider and the surrounding environment. The radar device acts as a mediator that actively probes the environment and translates object information into detectable signals, enabling the rider to perceive conditions that would otherwise be invisible or undetectable.
2Ease of operation
If riders focus attention on conditions in front of the bicycle, then forward navigation is improved, but riders cannot pay attention to conditions behind the bicycle
Solution Approach 1:
The radar system performs self-service detection by automatically scanning and monitoring the environment behind and beside the bicycle without requiring rider intervention. The system independently captures, processes, and presents object information, freeing the rider to focus on forward navigation while the system handles surrounding awareness.
Solution Approach 2:
The patent divides the detection field into multiple zones (front, rear, left, right) using separate radar components or detection beams. This segmentation allows simultaneous monitoring of different directions, with the left and right object detection components specifically addressing side conditions while the rider maintains forward focus.
3Reliability
If radar detection components are added to the bicycle, then object detection capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the radar detection components with the existing bicycle saddle structure. The housing of the saddle serves as the mounting structure for the radar device, integrating detection functionality into an existing component rather than adding separate complex structures. This reduces overall device complexity while maintaining detection capabilities.
Solution Approach 2:
The radar detection system is designed to perform multiple functions: detecting objects in front, behind, and beside the bicycle; providing warning signals; and potentially integrating with existing bicycle alarm systems. This multi-functionality reduces the need for separate specialized components, simplifying the overall system architecture.

AI summary
A radar detection and warning device includes a left object detection component and a right object detection component, which is combined with a saddle. A control unit is electrically connected to the left object detection component and the right object detection component. The control unit generates a driving signal to a warning device to generate a warning when receiving a warning signal from the left object detection component and/or the right object detection component. The radar detection and warning device also includes a left warning light and a right warning light for further warning purposes.
