Kickstand Variable Resistor Power Control for Shared Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of shared personal mobility devices face unintended usage fees when they fail to return the device through the user terminal after parking it using the kickstand, and there is a need to manage power supply efficiently to minimize energy consumption and fees.
Innovation Solution
A personal mobility device with a rotatable kickstand and a variable resistor that adjusts power supply based on the kickstand's position, including a controller that terminates or minimizes power when the kickstand is in a parking position, and adjusts communication settings to reduce power consumption and usage fees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the personal mobility device remains powered on after parking, then the user can quickly resume usage, but unintended usage fees occur and energy is wasted
Solution Approach 1:
The power supply state is dynamically adjusted based on kickstand position. When the kickstand is detected in the parking position, the controller automatically transitions the device from a powered-on state to a power-saving or powered-off state, creating a dynamic adaptation to usage conditions that prevents energy waste while maintaining operational readiness when needed
Solution Approach 2:
The system uses the kickstand position as feedback to automatically control power supply. The variable resistor detects kickstand position and provides feedback to the controller, which then adjusts power supply accordingly, creating a closed-loop system that prevents unintended usage fees without requiring manual user input
2Reliability
If the controller continuously monitors kickstand position and communicates with user terminal, then return status is confirmed, but power consumption increases
Solution Approach 1:
The controller implements periodic communication only when the kickstand is detected in the parking position, rather than continuous communication. This periodic action triggered by specific conditions (kickstand position) maintains reliable return status confirmation while significantly reducing overall power consumption compared to continuous monitoring and communication
Solution Approach 2:
The system changes communication parameters based on kickstand position. When parked, the controller activates communication to confirm return status; when in use, communication is minimized or suspended. This parameter change in communication activity based on operational state maintains reliability while managing power consumption
3Extent of automation
If the variable resistor is added to detect kickstand position, then power supply control is enabled, but device complexity increases
Solution Approach 1:
The variable resistor serves multiple functions: it detects kickstand position, provides feedback to the controller, and enables automatic power supply control. By making this single component multi-functional, the system achieves high automation without proportionally increasing complexity, as one component performs multiple critical roles in the automated control system

AI summary
A personal mobility that adjusts power supply based on a state of a kickstand is provided. The personal mobility includes a main body, a kickstand provided rotatably on one end in the main body, and a variable resistor that is provided on an axis of the kickstand as an axis. The variable resistor is configured to output a voltage that varies based on a position of the kickstand. A controller is then configured to adjust power supply when the position of the kickstand is a parking position.
