Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for human-powered vehicles lack efficient power management, leading to high power consumption and reduced battery life, especially when in idle or low-use states.
Innovation Solution
A wireless communication device with a controller that detects changes in a switch state to automatically switch between power modes, reducing power consumption by transitioning from a high power mode to a lower power mode when not in use, and vice versa based on user input or system activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communicator operates in the first mode (high power consumption), then the communication performance and responsiveness are improved, but the power consumption increases
Solution Approach 1:
The wireless communication device dynamically switches between first mode (high power consumption, high responsiveness) and second mode (low power consumption, low responsiveness) based on operational needs. The controller monitors switch state changes and automatically transitions modes, allowing the system to adapt its power consumption and communication performance characteristics to current usage conditions.
Solution Approach 2:
The system changes operational parameters by switching between two distinct power consumption modes. The first mode operates with higher power consumption for improved communication performance, while the second mode reduces power consumption for extended battery life. The controller adjusts these parameters based on detected switch state changes and communication signal presence.
2Duration of action of moving object
If the wireless communicator operates in the second mode (low power consumption), then the battery life is extended, but the communication responsiveness deteriorates
Solution Approach 1:
The system dynamically transitions between second mode (low power consumption) and first mode (high power consumption) based on operational requirements. When the controller detects switch state changes or receives communication signals, it automatically switches from the power-saving second mode to the performance-oriented first mode, ensuring responsiveness is restored when needed.
Solution Approach 2:
The operational parameters are adjusted by switching between two power consumption modes. The second mode maintains low power consumption to extend battery life, while the first mode provides high communication performance. The controller manages these parameter changes based on switch state detection and communication signal monitoring.
3Use of energy by moving object
If a mode switching mechanism is added to the wireless communication device, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The wireless communication device performs self-service by automatically detecting switch state changes and autonomously switching between power consumption modes without requiring complex external control systems. The controller monitors the switch state and communication signals, then automatically transitions modes based on predefined conditions, reducing the need for additional complexity.
Solution Approach 2:
The system implements feedback control by monitoring switch state changes and communication signal presence, then using this information to automatically adjust power consumption modes. The controller receives feedback from the switch and communication interface, processes this information, and switches modes accordingly, creating a closed-loop control system that manages power consumption efficiently.

AI summary
A wireless communication device for a human-powered vehicle comprises a wireless communicator and a controller. The wireless communicator is configured to wirelessly communicate with an additional wireless communicator. The wireless communicator has a first mode in which the wireless communicator operates under a first power consumption and a second mode in which the wireless communicator operates under a second power consumption which is lower than the first power consumption. The controller is configured to detect a change in a state of at least one switch. The controller is configured to set the wireless communicator with the first mode if the controller detects the change in the state of the at least one switch as the wireless communicator is in the second mode.
