Engineering Contradiction Analysis
1Length of moving object
If traditional skateboard trucks and mounts are used, then the structure is simple and easy to manufacture, but the turning radius is limited to relatively large radii
Solution Approach 1:
The skateboard truck system is divided into separate functional components: a traditional truck assembly and a spaced bushing mount assembly. The spaced bushing mount is positioned at a distance from the truck pivot point, creating a lever arm that amplifies turning effectiveness. This segmentation allows the turning radius to be reduced without requiring complete redesign of the entire truck system, maintaining manufacturing simplicity while achieving the desired compact turning capability.
Solution Approach 2:
The invention introduces a spatial dimension by positioning the spaced bushing mount at a distance from the truck pivot point rather than directly at the pivot. This creates a lever arm extending in the direction perpendicular to the turning axis, effectively using dimensional placement to reduce turning radius. The spaced bushing mount acts at a remote location, creating a mechanical advantage that reduces the radius of rotation without increasing the complexity of individual components.
2Ease of operation
If spaced bushing skateboard truck and mount are implemented, then smaller turning radii and robust return to horizontal are achieved, but the device complexity increases
Solution Approach 1:
The invention modifies the mechanical parameters of the truck system by introducing spaced bushings with specific dimensional parameters (distance from pivot point, bushing diameter, bushing material properties). These parameter changes create a lever arm effect that enhances turning responsiveness and enables smaller turning radii. The spaced bushing configuration changes the effective mechanical advantage, allowing more aggressive maneuvers while the modular design keeps the complexity increase manageable through standardized component specifications.
