Dynamo-Based Wheel Triggering for Battery Wake-Up Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in powering and waking up shared micromobility vehicles, such as scooters and bicycles, due to complex activation processes, leading to confusion and potential misuse of non-operational vehicles.
Innovation Solution
Integration of a dynamo associated with the wheel to detect movement and transmit a signal to a control module, which then wakes up the battery from a battery-off state, eliminating the need for manual activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual activation button or sequence is used to power up the vehicle, then the battery can be controlled to wake up, but the user experience becomes difficult and confusing
Solution Approach 1:
The system automatically detects wheel movement through the dynamo and triggers battery wake-up without requiring manual user input. The vehicle self-activates when the user naturally attempts to move it, eliminating the need for separate power button pressing or sequence following.
Solution Approach 2:
The patent replaces the manual mechanical button-pressing activation method with an automatic sensing system using a dynamo that detects wheel movement and electronically triggers battery wake-up, substituting mechanical user interaction with automated electromechanical detection.
2Use of energy by moving object
If the vehicle remains in battery-off state to conserve energy, then energy is preserved, but users cannot easily determine if the vehicle is operational
Solution Approach 1:
The system performs preliminary detection of user intent through wheel movement before activating the battery. The dynamo detects when the user attempts to move the vehicle and preemptively triggers battery wake-up, ensuring the vehicle is ready exactly when needed without premature activation.
Solution Approach 2:
The system provides immediate feedback by detecting wheel movement and automatically responding with battery activation. This closed-loop feedback ensures the vehicle transitions from off to on state based on real-time user interaction, eliminating uncertainty about operational status.
3Reliability
If a manual power button sequence is required, then battery activation can be controlled, but the device complexity increases
Solution Approach 1:
The patent extracts the manual activation button and sequence requirements from the system, retaining only the essential battery control functionality. By removing the need for user-initiated power buttons and complex sequences, the system simplifies the activation mechanism while maintaining reliable battery management.

Function Achieved in This Case
Simplifies the power-up process for users, ensuring vehicles are easily operational and reducing instances of users assuming vehicles are non-functional when they are actually ready to ride.
Implementation Method 1
a dynamo associated with the wheel and configured to transmit a first signal based at least on a detection of one or more movements of the wheel
Data Source
AI summary
A micromobility transit vehicle may include a wheel, a dynamo, a control module, and a battery. The dynamo may be associated with the wheel and configured to transmit a first signal based at least on a detection of one or more movements of the wheel that meets or exceeds a threshold movement of the wheel. The control module may be configured to receive the first signal transmitted by the dynamo. The control module may be configured to transmit a second signal upon receiving the first signal from the dynamo. The battery may be configured to receive the second signal transmitted by the control module. The second signal may cause the battery to wake from a battery-off state to a battery-on state.
