Controller Mode Switching for Human-Powered Vehicle Operating Device
Solution Overview
Problem
Human-powered vehicles face challenges in optimizing power consumption of operating devices, leading to inefficiencies in energy use and increased costs.
Innovation Solution
The operating device for human-powered vehicles incorporates a controller that dynamically switches between different power consumption modes based on user input and detected conditions, including a waiting mode, activating mode, and sleep mode, to minimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the controller operates continuously in high power mode, then the response speed and functionality are improved, but the power consumption increases
Solution Approach 1:
The controller dynamically adjusts its operating mode between first mode (lower power consumption) and second mode (higher power consumption) based on real-time detection of user input through the electric switch. This dynamic adaptation allows the system to maintain high responsiveness when needed while minimizing power consumption during idle periods, directly resolving the contradiction between response speed and power consumption.
Solution Approach 2:
The controller changes its operational parameters by switching between different power consumption modes. In the first mode, the controller operates with lower power consumption for extended battery life, while in the second mode, it operates with higher power consumption to provide enhanced functionality and faster response. This parameter change approach enables the system to optimize the balance between speed and energy usage.
2Use of energy by moving object
If the controller switches modes frequently, then the power consumption is optimized, but the device complexity increases
Solution Approach 1:
The controller's operation is segmented into distinct modes (first mode and second mode) with clearly defined transition conditions. This segmentation simplifies the control logic by creating discrete, manageable states rather than continuous complex adjustments. The electric switch provides clear transition triggers, making the mode switching mechanism straightforward to implement and manage despite the dynamic nature of the power optimization.
3Duration of action of moving object
If the controller remains in low power mode, then the battery life is extended, but the response time to user input increases
Solution Approach 1:
The system prepares for potential user interaction by maintaining the capability to quickly transition from first mode to second mode upon detecting user input through the electric switch. While operating in first mode to conserve battery, the controller remains ready to switch to second mode instantaneously when triggered, thus preserving both extended battery life and rapid response capability without requiring continuous high-power operation.

AI summary
An operating device for a human-powered vehicle comprises a base member, an operating member, an electric switch, and a controller. The operating member is movably coupled to the base member. The electric switch is configured to receive a user input in response to a movement of the operating member to operate an additional device. The controller is configured to change a mode of the controller at least between a first mode in which the controller is configured to be under first power consumption and a second mode in which the controller is configured to be under second power consumption different from the first power consumption.
