Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skateboards with four wheels experience bumpy rides due to independent trucks, limiting access to uneven surfaces and posing safety risks during tricks, while coolers are difficult to maneuver on varied terrains and lack stability for children or multiple items.
Innovation Solution
A single-wheel fork truck system with internally mounted motors and magnetic shoe and deck coupling enhances stability and safety, allowing skateboards to traverse diverse surfaces, and a treaded cooler design provides ease of use and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a four-wheel skateboard system with independent trucks is used, then the skateboard can provide basic mobility and trick capability, but it produces a bumpy ride and limits access to uneven surfaces
Solution Approach 1:
The skateboard system is divided into separate fork assemblies, each with its own wheel and motor. The first fork assembly has a first wheel and the second fork assembly has a second wheel, allowing independent operation and improved adaptability to uneven surfaces while maintaining ride smoothness through separate suspension paths
Solution Approach 2:
The skateboard transitions from a conventional four-wheel configuration to a two-wheel configuration with forks positioned at different heights and orientations. This dimensional reconfiguration allows the wheels to navigate uneven surfaces more effectively while the fork structure provides stability
2Adaptability or versatility
If conventional skateboard trucks with metal hangers are used for grinding tricks, then trick performance is enabled, but community property damage and skateboard component wear occur
Solution Approach 1:
The metal hanger grinding system is replaced with a magnetic coupling system. Magnets are embedded in the fork hangers and corresponding magnets are placed on the skateboard deck, creating a magnetic field that replaces the mechanical grinding contact. This eliminates wear and property damage while maintaining trick capability
Solution Approach 2:
The interaction mechanism changes from mechanical contact (grinding) to magnetic field interaction. The magnetic coupling allows the forks to interact with the deck without physical contact, changing the parameter of contact force from high (grinding) to near-zero (magnetic coupling)
3Power
If motors are externally mounted on skateboard decks, then propulsion is provided, but the components are exposed to elements and interfere with maneuverability
Solution Approach 1:
The motors are nested within the wheel assemblies rather than being externally mounted on the deck. Each wheel contains an integrated motor, protecting the components from elements and eliminating interference with maneuverability while maintaining propulsion capability
Solution Approach 2:
The motor and wheel are merged into a single integrated assembly. The motor is positioned inside the wheel structure, combining the propulsion function with the rolling function, which eliminates separate mounting components and improves maneuverability
4Stability of the object's composition
If four-wheel skateboards are used, then basic stability is provided, but the bumpy ride limits performance on varied terrains
Solution Approach 1:
The skateboard system uses dynamic fork assemblies that can independently adjust to terrain variations. Each fork with its wheel and motor can move and adapt separately, providing both stability through the fork structure and adaptability to varied terrains through independent wheel movement
