Bicycle Shift Lever Low-Battery Alert With Threshold Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-powered vehicles with electric power sources face challenges in reducing power consumption while effectively informing users about the remaining level of the electric power supply.
Innovation Solution
An operating device for human-powered vehicles that includes a base structure, an operating member, and an output unit, which selectively outputs information about the electric power source's remaining level based on a threshold, reducing unnecessary power consumption by omitting notifications when the level is above the threshold and ensuring notifications when the level is below it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the output unit continuously outputs information about the remaining power level, then the user is always informed of the power status, but the power consumption increases
Solution Approach 1:
The output unit outputs information about the remaining power level only at specific intervals or under specific conditions (when the remaining level is lower than the threshold), rather than continuously. This periodic output reduces power consumption while still keeping the user informed of the power status when necessary.
Solution Approach 2:
The system changes the parameter of information output based on the remaining power level. When the remaining level is above the threshold, no information is output. When it drops below the threshold, information is output. This dynamic parameter change optimizes power consumption while maintaining necessary information delivery.
2Use of energy by moving object
If the output unit outputs information only when power is low, then power consumption is reduced, but the user may not be aware of power status when it is sufficient
Solution Approach 1:
The system implements feedback by monitoring the remaining power level and comparing it with a predetermined threshold. Based on this feedback, the output unit decides whether to output information. This feedback mechanism ensures that information is provided at the most critical moment (when power is low) rather than continuously, optimizing power consumption while maintaining user awareness when necessary.
3Use of energy by moving object
If a threshold-based notification system is implemented, then power consumption is reduced by omitting unnecessary notifications, but the device complexity increases
Solution Approach 1:
The system uses a simple parameter change approach by comparing the remaining power level with a predetermined threshold. This simple comparison logic determines whether to output information, achieving power consumption reduction with minimal increase in device complexity. The threshold value can be easily adjusted without complicating the overall system.

AI summary
An operating device of a human-powered vehicle comprises a base structure, an operating member, and an output unit. The base structure is mountable to the human-powered vehicle. The operating member is movable relative to the base structure in response to a user input operation. The output unit is configured to output, in response to the user input operation, first information indicating that a remaining level of an electric power source is lower than a remaining-level threshold in a case where the remaining level is lower than the remaining-level threshold. The output unit is configured to be free of outputting, in response to the user input operation, second information indicating that the remaining level of the electric power source is higher than the remaining-level threshold in a case where the remaining level is higher than the remaining-level threshold.
