Solution Overview

Problem

Existing bicycle manual control devices experience delays in transmitting control signals due to the need for cyclist intervention to wake the system from standby mode, which can lead to inefficiencies in synchronous electronic systems and reduced energy efficiency.

Innovation Solution

A bicycle manual control device with a movement detector that emits a wake signal to bring the on-board electronics from standby to operating mode, allowing continuous readiness to transmit control signals when the bicycle is in use, and entering standby mode only during prolonged stops, thus minimizing signal delay and conserving energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the on-board electronics enters standby mode to save energy, then energy efficiency is improved, but signal transmission delay increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsignal transmission delay
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The movement detector is configured to detect bicycle movement and generate a wake signal that activates the on-board electronics from standby mode before the cyclist actually operates the manual actuation member. This preliminary activation ensures the electronics are ready to process and transmit control signals immediately when needed, eliminating delays while maintaining energy savings during non-use periods.

Inventive Principle:
Principle #10Preliminary action

2Speed

If the on-board electronics remains in operating mode continuously, then signal transmission speed is improved, but energy consumption increases

Engineering Contradiction:
Improvesignal transmission speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between standby mode and operating mode based on detected bicycle movement. The movement detector triggers a wake signal that transitions the on-board electronics from low-power standby mode to full operating mode, providing optimal signal transmission speed only when the bicycle is in use, thereby minimizing overall energy consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The on-board electronics alternates between standby mode and operating mode based on periodic detection of bicycle movement. During prolonged stops, the system enters standby mode to conserve energy, and activates to operating mode when movement is detected, creating a rhythmic pattern of power states that balances performance and energy efficiency.

Inventive Principle:
Principle #19Periodic action

3Use of energy by moving object

If the system activates on cyclist intervention, then energy efficiency is improved, but system responsiveness deteriorates

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsystem responsiveness
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The movement detector performs preliminary detection of bicycle movement and triggers a wake signal that activates the on-board electronics before the cyclist operates the control device. This ensures the system is already responsive and ready to process control signals immediately when the cyclist acts, eliminating any perceptible delay while maintaining energy efficiency during non-use periods.

Inventive Principle:
Principle #10Preliminary action
