Solution Overview
Problem
Existing motorized skateboards face issues with complex electrical connections, exposed wiring prone to damage, and lack of quick release mechanisms, making maintenance and component replacement difficult for users, requiring specialized tools and expertise.
Innovation Solution
A motorized wheel assembly with a quick release mechanism and integral plug and socket system, where the motorized wheel is easily removable without tools, and wiring is routed internally through the axle, hanger, and truck, eliminating the need for external connections and reducing the complexity of electrical handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motorized wheels are permanently fixed to the skateboard frame, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The motorized wheel assembly is divided into separable components: the wheel hub motor assembly can be detached from the skateboard frame using a quick-release mechanism. This segmentation allows the wheel to be removed and replaced independently while maintaining structural integrity during operation, resolving the contradiction between stability and ease of repair.
2Ease of operation
If electrical wiring is routed externally for easy access, then ease of operation is improved, but reliability deteriorates due to exposed wiring prone to damage
Solution Approach 1:
The electrical wiring is nested within the hollow interior of the axle tube, which itself is nested within the motorized wheel assembly. This nested configuration protects the wiring from external damage while keeping connections accessible through the quick-release mechanism, resolving the contradiction between operational ease and wiring durability.
3Reliability
If complex electrical connection systems are used for reliable power transmission, then reliability is improved, but device complexity increases
Solution Approach 1:
The electrical connection system is merged with the mechanical quick-release mechanism. When the wheel hub motor assembly is attached to the skateboard frame, electrical contacts automatically engage through the same mounting interface, combining mechanical and electrical connections into a single integrated action. This reduces device complexity while maintaining reliable electrical power transmission.
