Automatic Locking System for Pedal Traction

Solution Overview

Problem

Current machines actuated by pedal levers require manual coupling and decoupling, distracting users by requiring them to take their hands off the handlebar and eyes off the road.

Innovation Solution

An automatic locking/unlocking system for traction systems actuated by pedal levers, utilizing an electronic actuator and control means to move a blocking element between coupled and uncoupled positions without manual intervention, allowing seamless engagement and disengagement from the handlebar or foot without hand or eye diversion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual coupling and decoupling systems are used in pedal lever machines, then the system structure remains simple, but the user must take hands off the handlebar and eyes off the road, reducing safety and convenience

Engineering Contradiction:

Improvecoupling operation convenienceVSAvoiduser safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system automatically detects when the pedal lever should be coupled or decoupled and performs the coupling operation without requiring manual intervention from the user. The automatic coupling device monitors system conditions and actuates the coupling mechanism autonomously, eliminating the need for users to manually engage or disengage the coupling while maintaining safety and operational convenience

Inventive Principle:

Principle #25Self-service

2Ease of operation

If automatic locking/unlocking system is implemented, then user safety and convenience are improved, but device complexity increases due to electronic actuators and control means

Engineering Contradiction:

Improvecoupling operation convenienceVSAvoidsystem structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical coupling operations with an automated system that uses electronic actuators and control means to perform the coupling and decoupling actions. This substitution eliminates the need for manual intervention while managing complexity through integrated control systems that automatically monitor and execute coupling based on operational conditions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If manual coupling mechanism is used, then device complexity remains low, but user attention is diverted from the road, creating safety hazards

Engineering Contradiction:

Improvecoupling system structureVSAvoidriding safety

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system automatically detects when the pedal lever should be coupled or decoupled and performs the coupling operation without requiring manual intervention from the user. The automatic coupling device monitors system conditions and actuates the coupling mechanism autonomously, eliminating the need for users to manually engage or disengage the coupling while maintaining safety and operational convenience

Inventive Principle:

Principle #25Self-service
