Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric bicycles face challenges in efficiently pairing removable battery packs and other electronic components without user intervention, leading to mechanical packaging issues and difficulty in using multiple battery packs or sharing them among riders.
Innovation Solution
Implementing a wireless communication system with sensors (reed switch, Hall-effect sensor, or NFC tag) to detect matching components, enabling automatic pairing by synchronizing power-on times and initiating communication between battery packs and electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic pairing is implemented using wireless communication and power-on time synchronization, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs automatic pairing without user intervention by having electronic components self-identify through power-on time synchronization. When power is applied, components automatically transmit their power-on timestamps via wireless communication, and the system autonomously completes the pairing process based on time comparison, eliminating the need for manual pairing operations.
Solution Approach 2:
The system performs preliminary identification and synchronization actions during the power-on sequence itself. By capturing and transmitting power-on timestamps immediately when power is applied, the system prepares pairing information in advance, allowing automatic matching to occur before the user even becomes aware of the pairing process.
2Adaptability or versatility
If multiple battery packs are made interchangeable through automatic pairing, then adaptability is improved, but reliability may worsen due to potential pairing errors
Solution Approach 1:
The system uses power-on time synchronization as a feedback mechanism to verify successful pairing. By comparing the transmitted power-on timestamp with the received timestamp, the system can confirm that the correct battery pack is paired with the correct electronic component, providing a reliable verification method that prevents mismatched pairings while enabling battery interchangeability.

Data Source
AI summary
An electronic component for a bicycle includes a communication interface and a processor in communication with the communication interface. The processor is configured to identify a first power on time. The first power on time identifies a time at which the electronic component was powered on by a power source of the bicycle. The processor is configured to listen for one or more messages after the electronic component is powered on and receive, via the communication interface, a message of the one or more messages. The received message is from another electronic component of the bicycle and identifies a second power on time. The second power on time is for the other electronic component. The processor is configured to compare the second power on time to the first power on time and initiate, based on the comparison, pairing of the other electronic component with the electronic component.
