Bicycle Controller Frequency Diversity for Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems in bicycles lack stability due to interference from signals with the same center frequencies, leading to decreased communication speed and potential instability.
Innovation Solution
A bicycle controller system that uses multiple interfaces to receive and transmit wireless signals with different center frequencies, allowing for the establishment of data links between various bicycle components, and dynamically changes frequencies to avoid interference, thereby improving communication stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to transmit data between bicycle components, then communication flexibility and ease of operation are improved, but communication stability and reliability deteriorate due to signal interference from similar frequencies
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the center frequency of wireless signals. The controller receives signals at different center frequencies (first frequency for first component, second frequency for second component) and transmits control signals at a third frequency, thereby changing the frequency parameter to avoid interference and improve communication reliability while maintaining wireless flexibility
2Device complexity
If multiple bicycle components communicate using the same frequency band, then device complexity is reduced, but harmful interference between signals increases
Solution Approach 1:
The patent applies local quality by assigning different center frequencies to different communication interfaces. The first interface operates at a first center frequency for receiving first wireless signals, the second interface operates at a second center frequency for receiving second wireless signals, and the third interface transmits at a third center frequency. This frequency differentiation creates local quality variations that eliminate signal interference while maintaining relatively simple device structure

AI summary
A bicycle controller is configured to communicate with a first bicycle component that transmits a first wireless signal and a second bicycle component that transmits a second wireless signal. The bicycle controller includes an interface configured to receive the first wireless signal and the second wireless signal. The first wireless signal has a center frequency that is a first frequency. The second wireless signal has a center frequency that is a second frequency. The second frequency differs from the first frequency.
