Bicycle Speed Feedback Notifications for Appropriate Riding Pace
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for bicycles, particularly electrically assisted bicycles, to maintain appropriate traveling speeds to ensure user comfort and efficiency, and users need awareness of maintaining these speeds.
Innovation Solution
A notification system using a processor and storage to monitor and notify users when they maintain or exceed predetermined speed thresholds, adjusting notification criteria based on speed and duration, and utilizing a mobile terminal device for communication, thereby improving user awareness of appropriate speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system notifies the user when appropriate speed is maintained, then user awareness of appropriate speed is improved, but the notification system complexity increases
Solution Approach 1:
The notification system continuously monitors traveling speed and provides feedback to the user when appropriate speed is maintained or exceeded. The processor compares actual speed with predetermined speed thresholds and triggers notifications accordingly, creating a closed-loop feedback system that improves user awareness without requiring complex manual monitoring
Solution Approach 2:
The system uses the bicycle's existing sensor and communication capabilities to perform speed monitoring and notification functions. By leveraging already-present components (speed sensors, mobile terminal communication), the system avoids adding significant complexity while achieving the self-monitoring and user notification functionality
2Measurement precision
If the system uses multiple speed thresholds and duration counting, then speed monitoring precision is improved, but the control logic complexity increases
Solution Approach 1:
The speed monitoring is divided into distinct segments using multiple thresholds: a first predetermined speed threshold for basic appropriate speed determination, and a second higher threshold for detecting sustained excessive speed. This segmentation allows precise monitoring of different speed conditions without requiring a single complex continuous control logic
Solution Approach 2:
The system pre-establishes multiple speed thresholds and notification conditions before operation. The processor is configured with predetermined speed values and time durations that define when notifications should occur, allowing the system to respond to speed variations without complex real-time decision-making logic

AI summary
A notification system for notifying a user of information on driving of a bicycle includes a processor and a storage to store a computer program to control an operation of the processor. The processor is configured or programmed to execute the computer program to acquire traveling speed information representing a traveling speed of the bicycle, perform a first count operation of counting a time duration in which a first state of the traveling speed not being higher than a first predetermined speed, is continued based on the traveling speed information, and in a case in which the first state has been continued for a first predetermined time duration, notify the user via a notifier of first information indicating that the driving of the bicycle by the user has been appropriate.
