Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycle electric components face challenges in reducing power consumption when not in operation, as existing technologies do not efficiently manage power states or communication modes to minimize energy usage during idle periods.
Innovation Solution
The bicycle electric component incorporates a wireless communicator, a power source, and a switcher with an electric generator that connects and disconnects the power source based on bicycle operation, along with an electromagnetic shield and sensitivity changer to adjust communication and power modes, enabling automatic power-saving features when the bicycle is not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communicator remains continuously powered and connected, then communication functionality is maintained, but power consumption increases during idle periods
Solution Approach 1:
The patent implements dynamic power management by switching the wireless communicator between powered and unpowered states based on operational detection. The switcher dynamically connects or disconnects the power source from the wireless communicator depending on whether the bicycle is detected as being in use, optimizing power consumption while maintaining communication reliability when needed.
Solution Approach 2:
The system employs automatic detection mechanisms that sense bicycle operation status and autonomously control the power connection state without user intervention. The detector identifies when the bicycle is in use and the switcher automatically adjusts power supply accordingly, enabling the system to self-manage its power consumption based on actual operational needs.
2Use of energy by moving object
If the electromagnetic shield covers the wireless communicator to block signals, then power consumption is reduced, but communication capability is lost
Solution Approach 1:
The electromagnetic shield is dynamically positioned between covering and uncovered states based on operational status. When the bicycle is detected as not being in use, the shield covers the wireless communicator to block signals and reduce power consumption. When operation is detected, the shield moves to an uncovered position to restore full communication capability.
Solution Approach 2:
The electromagnetic shield acts as an intermediary element that physically blocks electromagnetic signals when in the covering position. This intermediary structure provides a mechanical means to control signal reception and transmission, enabling the system to reduce power consumption by blocking signals during idle periods while maintaining full communication capability when needed.
3Use of energy by moving object
If the switcher continuously monitors and adjusts power connection state, then power saving is optimized, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated components. The switcher integrates power connection control with operational detection capabilities, and the electromagnetic shield structure incorporates both shielding function and positional indication features. This merging reduces the need for separate control systems and simplifies the overall device architecture while maintaining optimized power management.
