Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skateboards are bulky, making them difficult to transport and requiring significant physical effort, especially when riding uphill, due to their large dimensions and lack of efficient mobility solutions.
Innovation Solution
A foldable skateboard design with a first and second platform connected by a rotating frame system, allowing for reduced volume storage and equipped with an electric motor for effortless movement, enabling easy transportation and reduced physical exertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the skateboard uses a traditional single large platform design, then it provides sufficient standing area for the user, but it increases the volume making transportation difficult and requires shipping as checked luggage
Solution Approach 1:
The skateboard board is divided into two separate platforms (first platform and second platform) that can be folded relative to each other. This segmentation allows the skateboard to be collapsed into a compact form for easy transportation while maintaining sufficient standing area when in use.
Solution Approach 2:
The skateboard incorporates a folding mechanism with rotatable connection means that allows the board to dynamically change between an extended configuration (providing large standing area) and a folded configuration (reducing volume for transportation).
2Ease of operation
If the skateboard is designed as a rigid single platform, then it provides stable standing surface, but it requires significant physical effort from the user especially when riding uphill
Solution Approach 1:
The folding mechanism allows the skateboard to adapt its configuration based on usage needs. When folded, it reduces the distance between wheels for better maneuverability and reduced physical effort. When extended, it provides a larger standing surface for stability.
3Volume of moving object
If the skateboard uses a folding mechanism with rotatable frames, then it reduces volume for easy transportation, but it increases device complexity
Solution Approach 1:
The connection mechanism is divided into distinct modular components: connection means with rotatable axes, locking means with detachable elements, and releasing means. This modular segmentation makes the complex folding mechanism easier to manufacture, assemble, and maintain.
Solution Approach 2:
The folding mechanism uses simple rotatable connections and detachable locking elements that allow smooth transitions between folded and extended states. The design prioritizes mechanical simplicity in the movement components while providing stable locked positions when folded.
4Area of moving object
If the skateboard platforms are positioned far apart, then it provides larger standing area, but it increases the volume making it difficult to transport
Solution Approach 1:
The distance between the first and second platforms is made variable through the folding mechanism. When in use, the platforms are positioned far apart to maximize standing area. During transportation, the platforms are folded close together to minimize volume, and locking means maintain the compact configuration.
