Distributed Bicycle Electronic System Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle electronic systems often rely on centralized processing units, which can lead to system failures if the main processor malfunctions, and they lack a distributed architecture that allows for efficient power supply and communication between components.
Innovation Solution
A distributed architecture for bicycle electronic systems is implemented, featuring manual command management units and derailleur management units connected via direct communication channels, eliminating the need for a central processing unit and allowing for shared power supply through a bus system, with optional wireless communication for improved aerodynamics and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized processing unit is used to control bicycle electronic components, then the system structure is simplified and easier to manage, but the system reliability decreases because a single point of failure can cause entire system malfunction
Solution Approach 1:
The patent divides the centralized control system into multiple independent processing units, each responsible for specific functions (display-carrier unit, front derailleur unit, rear derailleur unit). This segmentation eliminates the single point of failure problem while maintaining manageable system structure through modular design.
2Ease of manufacture
If wireless communication is implemented between bicycle components, then aerodynamics are improved and assembly is simplified, but power transmission reliability may be compromised
Solution Approach 1:
The patent introduces a wireless transmission path as an intermediary medium to enable communication between processing units without physical connections. This allows aerodynamic optimization and simplified assembly while maintaining reliable power transmission through the battery unit's wireless power delivery capability.
