Bicycle Control System Single Power Supply Wireless Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of power supply for bicycle control systems with electric drive devices, such as transmission devices and suspensions, becomes laborious due to differing power consumption rates among these devices, requiring separate battery replacements.
Innovation Solution
A bicycle control system with a single power supply connected to multiple electric drive devices and an operating apparatus, allowing wireless operation and separate power supply for the operating apparatus, reduces the labor and cost associated with battery replacement and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery is incorporated into each electric drive device, then each device can operate independently with wireless control, but the maintenance of power supply becomes laborious due to different power consumption rates
Solution Approach 1:
The patent merges multiple separate power supplies (one for each electric drive device) into a single shared power supply unit. This consolidation allows all electric drive devices to be powered by one common battery, eliminating the need for multiple separate battery replacements and simplifying maintenance while preserving wireless operation capability.
2Ease of repair
If a single power supply is shared among multiple electric drive devices, then maintenance is simplified, but the flexibility of arrangement may be reduced
Solution Approach 1:
The patent segments the power supply system into a separate, modular power supply unit that can be independently positioned and configured. This segmentation allows the power supply to be placed in the most convenient location for maintenance while still providing power to all electric drive devices, thus maintaining arrangement flexibility despite using a single shared power source.
3Reliability
If wireless communication units are provided in each electric drive device, then each device can communicate independently, but the cost increases
Solution Approach 1:
The patent implements a universal wireless communication architecture where a single wireless communication unit serves multiple electric drive devices. This multi-functional approach allows one communication unit to control and communicate with all electric drive devices, reducing the total number of communication units needed and lowering overall system cost while maintaining reliable wireless operation.

AI summary
A bicycle control system is basically provided with a first power supply, a plurality of electric drive devices and an operating apparatus. The electric drive devices are electrically coupled to the first power supply to receive electric power supplied from the first power supply. The operating apparatus wirelessly operates the electric drive devices by wireless signals.
