Solution Overview

Problem

Current one-person skateboard vehicles for urban transport are complex to maneuver, require special skills, and are not lightweight, compact, or suitable for easy use by all users due to the need for significant deck oscillation to change direction and the inclusion of heavy motorized components with gears and belts.

Innovation Solution

A one-person vehicle with trucks that pivot and include a damper assembly between the pivot and control arm, allowing for easier direction change without large deck oscillation, combined with a compact motorization system and foldable design for enhanced usability and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a bushing element is used to compensate for weight force and facilitate deck return to center, then the vehicle can maintain stability, but the vehicle becomes complex to maneuver and requires special user abilities

Engineering Contradiction:
Improvedeck stabilityVSAvoidmaneuverability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent changes the mechanical parameters of the control arm system by introducing a damper assembly that modifies the rotational characteristics. The damper assembly allows the control arm to rotate more freely with reduced friction and resistance, enabling easier direction changes while maintaining stability through controlled damping forces.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the traditional bushing element with a damper assembly that uses controlled damping mechanics instead of pure friction-based bushing mechanics. This substitution allows for smoother, more predictable motion control that is easier to maneuver while maintaining stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If significant deck oscillation is used to change direction, then the vehicle can overcome the bushing resistance, but the vehicle requires special skills and is not easy to use by all users

Engineering Contradiction:
Improvedirection controlVSAvoiduser skill requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The damper assembly modifies the rotational parameters of the control arm, reducing the oscillation amplitude needed to initiate direction changes. This allows users without special skills to maneuver the vehicle easily by making small, natural body movements rather than requiring large, skillful oscillations.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The damper assembly acts as an intermediary between the user's weight shifts and the wheel direction changes, smoothing out the transmission of forces. This mediation allows intuitive control where small user inputs produce appropriate directional responses without requiring skillful oscillation techniques.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If motor, gears and belts are included to drive the truck wheel axles, then the vehicle can be motorized for urban transport, but the vehicle weight becomes very great and requires much maintenance

Engineering Contradiction:
Improvemotorized transport capabilityVSAvoidvehicle weight
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The patent extracts and removes the heavy mechanical transmission components (gears and belts) from the motorized system, retaining only the essential motor function. This extraction significantly reduces vehicle weight while maintaining the core capability of motorized wheel drive for urban transport.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes a simplified direct-drive motor system for the traditional motor-gear-belt transmission system. This substitution eliminates complex mechanical intermediaries, reducing weight, maintenance requirements, and mechanical failure points while preserving motorized propulsion capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles
