Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing training devices for children to ride bicycles and motorcycles fail to effectively teach balance, throttle control, and braking skills due to issues with seat height, weight, and the transition from balance bikes to pedal bikes, and lack realistic training tools for throttle control.

Innovation Solution

A convertible running bike that can transition from a non-motorized to a motorized configuration, featuring a lightweight frame, electronic motor control, and adjustable seat height, allowing children to learn balance and throttle control skills progressively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a standard bicycle with pedals and cranks is used, then children can learn pedaling skills, but the seat height is too high for young children to keep both feet on the ground

Engineering Contradiction:

Improveability to keep feet on groundVSAvoidseat height

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The bicycle seat height is made adjustable through a telescopic seat post that can be extended or retracted. This allows the seat height to be dynamically changed to match the child's height, enabling them to keep both feet on the ground while maintaining proper pedaling position.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The seat post is divided into multiple telescopic sections that can be independently adjusted. This segmentation allows for fine-tuned height adjustments to accommodate children of different ages and sizes, solving the contradiction between adequate seat height for pedaling and low enough height for ground contact.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a motorcycle engine is installed in a small motorcycle, then children can learn throttle control, but the weight and size become too heavy for smaller and younger children

Engineering Contradiction:

Improvethrottle control trainingVSAvoidbike weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The heavy mechanical motorcycle engine is replaced with a lightweight electric motor system. This substitution maintains the throttle control training function while dramatically reducing the overall weight and size of the vehicle, making it suitable for younger and smaller children.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The powertrain parameters are changed from a high-power combustion engine to a low-power electric motor with adjustable torque output. This allows the vehicle to provide sufficient throttle control training while keeping the weight manageable for children as young as three years old.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If training wheels are added to small motorcycles, then balancing skills can be trained separately from throttle control, but the training tool becomes less realistic

Engineering Contradiction:

Improveseparated skill trainingVSAvoidrealistic training experience

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The electric motorcycle is designed to serve multiple training functions simultaneously. It can teach balance, throttle control, and braking skills in an integrated, realistic motorcycle configuration without requiring training wheels, thereby maintaining authenticity while providing comprehensive skill development.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Length of stationary object

If a low seat height is provided for small children, then they can straddle the vehicle with feet on ground, but there is insufficient space for engine and other components

Engineering Contradiction:

Improveseat heightVSAvoidspace for components

Core Design Contradiction:

Length of stationary objectVSVolume of stationary object

Solution Approach 1:

The electric motor and battery components are arranged in a compact, vertically-integrated configuration that utilizes vertical space rather than horizontal space. This dimensional reorganization allows sufficient component accommodation within the limited space constraints imposed by the low seat height design.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The electric motor, battery, and control components are nested within each other and integrated into the frame structure. This nesting approach maximizes space utilization, fitting all necessary components within the compact chassis that accommodates a low seat height for young children.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A running bike is to be operated selectively with and without power. The running bike includes a front fork rotatably engaged with a front wheel, a rear fork rotatably engaged with a rear wheel, a handlebar coupled to the front fork for steering the running bike, a frame extending between and connecting the front fork and the rear fork, an electronic controller coupled to the frame, and a drivetrain assembly coupled to the frame and in communication with the electronic controller. The drivetrain assembly includes an electric motor configured to selectively drive the rear wheel. A battery selectively provides power to the drivetrain assembly. A clutch is coupled to the handlebar and is in communication with the electronic controller. The clutch is configured to be actuated by an operator to proportionally increase or decrease power to the drivetrain assembly electronically.
