Quick Release Wheel Truck Assembly for Roller Skates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel trucks for quad roller skates are not easily interchangeable, requiring users to carry multiple skates or use tools to change wheel types, which is time-consuming and inconvenient.
Innovation Solution
A wheel truck assembly with a base plate and two wheel trucks, where one wheel truck can be selectively removed and each wheel truck has a quick release assembly allowing for independent attachment and detachment of wheels, enabling users to easily switch between different wheel types and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheel trucks are used, then structural stability is maintained, but wheel interchangeability is poor and requires tools
Solution Approach 1:
The wheel truck assembly is divided into separable components: the base plate with wheel trucks and the wheels themselves. Each wheel can be independently attached or detached from its wheel truck through the quick release assembly, allowing users to interchange wheels without tools or complex procedures while maintaining structural stability when assembled.
2Adaptability or versatility
If multiple roller skates are carried for different wheel types, then wheel type versatility is achieved, but portability and convenience are reduced
Solution Approach 1:
The base plate with wheel trucks is designed as a universal platform that can accommodate different wheel types through the quick release assembly. Users can attach various wheels (indoor, outdoor, different sizes) to the same base plate, eliminating the need to carry multiple complete roller skates for different activities, thus reducing total weight while maintaining versatility.
3Reliability
If tools are used for wheel changes, then secure attachment is ensured, but time consumption increases
Solution Approach 1:
The quick release assembly enables users to attach and detach wheels manually without requiring external tools. The assembly includes a release mechanism that allows one-handed operation, making the wheel change process fast and tool-free while maintaining secure attachment when engaged, thus reducing wheel change time without sacrificing reliability.

AI summary
A wheel assembly having a plurality of wheel trucks spaced apart on a base plate for supporting a vehicle that uses the wheels of the wheel truck to move along a supporting surface. Each wheel truck provides two wheels sharing an independent axle in which each independent axle includes a quick release pin configured to both removably and rotatably connect the two wheels to the wheel truck.
