Solution Overview

Problem

Riders learning to balance on bicycles with training wheels face instability when the wheels are removed, leading to potential falls and injuries, as they transition from training wheels to balancing on two wheels without support.

Innovation Solution

A real-time retractable training wheel system that includes a lift activation assembly connected to a wheel mount assembly via a cable, allowing the training wheels to elevate or lower while in motion, providing adjustable stability and safety through a handlebar grip, lever, or switch activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If training wheels are attached to provide stability, then safety is improved, but the rider cannot practice balancing on two wheels

Engineering Contradiction:

ImprovesafetyVSAvoidbalancing practice capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The training wheel system dynamically adjusts its configuration by allowing the training wheels to be raised and lowered while the bicycle is in motion. The lift activation assembly with cable and ratchet mechanism enables real-time reconfiguration, transitioning from a stable two-wheel configuration to a two-wheel balance configuration during riding, thus adapting to different learning stages

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If training wheels are removed to enable two-wheel balancing, then balancing practice is improved, but safety deteriorates due to instability

Engineering Contradiction:

Improvebalancing practice capabilityVSAvoidsafety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system provides dynamic adjustment capability where training wheels can be raised or lowered based on riding conditions. The ratchet and lock mechanism ensures stable positioning at selected heights, allowing riders to practice balancing when needed while maintaining safety by deploying training wheels when instability occurs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables riders to self-regulate based on their balancing capability by manually operating the lift activation assembly. Riders can sense their own balance status and adjust training wheel elevation accordingly, creating a feedback loop between balancing performance and safety support

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If training wheels are made retractable to provide adjustable stability, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvestability adjustment capabilityVSAvoidmechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lifting function is extracted from the wheel assembly itself and integrated into the handlebar area through a separate lift activation assembly. This modular approach allows the training wheels to be raised or lowered independently through cable connection, reducing the complexity within the wheel mounting structure while maintaining adaptability

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A training wheel apparatus for learning to ride a bicycle includes a lift activation assembly. The training wheel apparatus further includes a wheel mount assembly configured to operatively connect to a wheel. The training wheel apparatus further includes a cable configured to operatively connect to the lift activation assembly and the wheel mount assembly. When activated, the lift activation assembly is configured to use the cable to change an elevation of the wheel between a first position and a second position while the wheel is in motion.
