Human-Powered Vehicle Component Wired Wireless Communication Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human-powered vehicles lack an efficient communication system that can seamlessly switch between wired and wireless communication channels, especially when the primary channel is unavailable, leading to disruptions in communication and increased power consumption.
Innovation Solution
An operated component for human-powered vehicles is designed with both wired and wireless communicators that can recognize and switch between continuous and intermittent listen states, allowing for efficient power management and reliable communication by using the wireless channel as a backup when the wired channel is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communicator continuously monitors wireless signals, then reliable signal recognition is achieved, but power consumption increases
Solution Approach 1:
The wireless communicator alternates between active listening states and sleep states, periodically monitoring wireless signals rather than continuously. This periodic action reduces power consumption while maintaining the ability to detect signals when needed, resolving the contradiction between reliable signal recognition and low power consumption.
2Reliability
If the wireless communicator is always active as backup, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The wireless communicator dynamically adjusts its operational state based on system needs, transitioning between active backup mode and sleep mode. This dynamic state adjustment ensures communication reliability is maintained when needed while minimizing power consumption during normal wired operation, resolving the contradiction between communication reliability and power consumption.
3Use of energy by moving object
If the wired communication channel is used exclusively, then power consumption is reduced, but communication reliability deteriorates when the channel is unavailable
Solution Approach 1:
The wireless communicator is pre-configured and maintained in a ready state (or periodically activated) before wired communication failure occurs. This preliminary preparation ensures that when the wired channel becomes unavailable, the wireless backup is immediately available to maintain communication, resolving the contradiction between low power consumption and communication availability.

AI summary
An operated component for a human-powered vehicle comprises a first wired communicator and a first wireless communicator. The first wired communicator has a first wired communication state in which the first wired communicator is configured to recognize a wired signal transmitted via a wired communication channel. The first wireless communicator has a first wireless communication state in which the first wireless communicator is configured to recognize a wireless signal transmitted via a wireless communication channel. The first wireless communicator is configured to be in the first wireless communication state while the first wired communicator is in the first wired communication state.
