Solution Overview

Problem

Existing bicycle communication systems do not effectively transmit information related to the control state of both the motor and shifting device, limiting user usability and integration of components.

Innovation Solution

A bicycle communication apparatus with a wireless communicator that transmits first information related to the motor and second information related to the shifting device through wireless communication, allowing users to acknowledge these states on an external device, and includes a base portion with an accommodation for the wireless communicator, enabling flexible placement and connection options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single wireless communicator is used to transmit both motor information and shifting device information, then device complexity is reduced and usability is improved, but information completeness may be compromised

Engineering Contradiction:
Improvenumber of wireless communication unitsVSAvoidcompleteness of transmitted information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent combines multiple wireless communication units into a single integrated communicator that transmits both motor control information and shifting device information through one antenna system, reducing device complexity while maintaining complete information transmission capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single wireless communicator is designed to perform multiple functions by transmitting different types of information (motor status, shifting device status, control commands) through the same communication interface, eliminating the need for separate dedicated communication units for each component

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the base portion is provided independently from the bicycle component, then adaptability and user placement flexibility are improved, but device complexity increases

Engineering Contradiction:
Improveplacement flexibility of base portionVSAvoidsystem integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into a separable base portion and bicycle component portion, allowing the base to be independently positioned and configured while maintaining functional connection through the wireless communicator, thus providing placement flexibility without requiring permanent integration

Inventive Principle:
Principle #1Segmentation

3Device complexity

If information from multiple controllers (first controller for motor, second controller for shifting device) is received and transmitted through a single wireless communicator, then device complexity is reduced, but communication reliability may be affected

Engineering Contradiction:
Improvenumber of wireless communication unitsVSAvoidcommunication reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The single wireless communicator acts as an intermediary that receives information from multiple controllers (first controller for motor, second controller for shifting device) and transmits it to external devices, consolidating multiple communication interfaces into one reliable transmission channel while maintaining data integrity from all sources

Inventive Principle:
Principle #24Intermediary (Mediator)
