Bicycle Basket Safety Detection and Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The safety of shared bike users, particularly children, is compromised as they are not prevented from sitting in the bicycle's basket, which is dangerous.
Innovation Solution
A safety reminding device integrated with a bicycle-sharing system that uses a detecting unit, such as infrared sensors and a temperature sensor, to identify if a person is sitting in the basket and generates a warning signal, deducting credit points or sending alerts to the user, and optionally includes a braking system to prevent unsafe usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shared bicycle is equipped with a basket, then the utility and convenience of the bicycle is improved, but the safety risk increases when children sit in the basket
Solution Approach 1:
The system performs preliminary detection of objects in the basket before allowing bicycle operation. The detecting unit continuously monitors the basket area, and the control unit is pre-programmed to prevent activation when a person is detected, thereby preventing dangerous situations before they occur.
Solution Approach 2:
The control unit acts as an intermediary between the detecting unit and the bicycle's operation system. It receives detection signals from the detecting unit and mediates by preventing the bicycle from being unlocked or operated when a person is present in the basket, thus blocking the harmful action path.
2Reliability
If a detecting unit is added to identify persons in the basket, then the safety monitoring capability is improved, but the device complexity increases
Solution Approach 1:
The detecting unit is designed with multi-functionality, serving both as a presence detection device and as a trigger for the warning and prevention mechanisms. The control unit also performs multiple functions including signal processing, decision-making, and system coordination, thereby reducing the need for separate dedicated components for each function.
Solution Approach 2:
The patent combines the detecting unit, control unit, warning unit, and prevention mechanism into an integrated safety system. The control unit merges signal processing, detection analysis, and control decision-making into a single processing core, reducing overall system complexity while maintaining comprehensive safety monitoring capability.
3Ease of operation
If a warning signal and credit deduction system are implemented, then the user behavior control is improved, but the system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the detecting unit continuously monitors the basket, the control unit processes the detection signals, and the warning unit provides immediate feedback to the user. The credit deduction system also provides feedback by penalizing unsafe behavior, creating a closed-loop control system that guides user behavior without requiring complex manual intervention.

AI summary
A safety reminding device for a bicycle with a basket or other carrying structure includes a detecting unit to detect whether an object in the basket or other structure of a bicycle is a person when determining that the bicycle is unlocked. The device can output a warning signal when determining that a person is sitting in the basket, to warn the user that the basket is forbidden as a seat, and a server of this system can also impose penalties on the user, such as credit point deductions, and also apply the brakes of the bicycle braking system until the forbidden situation is ended. A safety reminding method is also provided.
