Solution Overview

Problem

Current electric scooters lack balancing and fireproofing features, posing increased risks of injury and fire damage, especially for elderly, disabled, or untrained users, and existing scooters are difficult to modify safely and cost-effectively.

Innovation Solution

A balance assistance and fireproofing device comprising training wheels and fire-suppressant materials that can be retrofitted onto existing scooters, providing stability and fire protection through adjustable attachment to the standing platform.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If training wheels are added to improve balance stability, then the scooter becomes more stable and easier to ride, but the device complexity increases

Engineering Contradiction:
Improvescooter stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The balance assistance device is divided into separate modular components: training wheels that can be attached to the standing platform, fireproofing units that wrap around batteries, and adjustable support structures. This segmentation allows each component to perform its specific function independently while maintaining overall system stability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The training wheels act as an intermediary element between the ground and the standing platform, providing additional support points that enhance stability. The fireproofing units serve as intermediaries between the batteries and the surrounding environment, preventing fire spread while allowing the scooter to continue operating.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If fireproofing units are added to protect batteries, then fire safety is improved, but the device complexity increases

Engineering Contradiction:
Improvefire riskVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The fireproofing function is extracted as a separate, removable unit that can be independently attached to or removed from the scooter. This allows the fire safety feature to be implemented without permanently modifying the scooter's core structure, reducing overall device complexity while maintaining enhanced fire protection.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fireproofing units utilize flexible fire-resistant materials that can conform to the battery shape and be easily attached or removed. These flexible shells provide fire protection without adding rigid structural complexity, allowing for simple installation and removal by users.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of operation

If the device is made adjustable and removable for user customization, then ease of operation is improved, but the device complexity increases

Engineering Contradiction:
ImproveadjustabilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device incorporates dynamic, adjustable components such as training wheels with adjustable positions and angles, and fireproofing units that can be easily attached and removed. This allows users to customize the device according to their needs and skill levels while maintaining relatively simple construction through standardized adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed herein are exemplary devices that provide balance assistance and fireproofing to electric scooters. The devices described herein can be clipped onto existing scooters, providing balance improvements via one or more training wheels and providing fireproofing improvements via one or more units containing fire-suppressant materials. A device may be attached to the center of a scooter's standing platform to improve the stability of the scooter and to provide fireproofing to the batteries. The device can include two training wheels, each positioned to an opposite side of the standing platform, to provide the vehicle with stability. The training wheels may be connected to an axle that is mounted to a fireproofing unit. The fireproofing unit, which contains fire-suppressant materials, can clamp to the standing platform, which contains at least a portion of the batteries. Users can adjust, reposition, and/or remove portions of the balance assistance and fireproofing device.
