Skateboard Base Plate Buffering for Uneven Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skateboards are unable to navigate uneven roadways or stairs due to the lack of effective buffering mechanisms.
Innovation Solution
The skateboard assembly incorporates a keel structure coupled with a base plate, along with buffer members and retaining members, which allows for enhanced stability and maneuverability on uneven surfaces by using a combination of through holes, grooves, and fastening members to secure the truck to the base plate, and pivotally engaging wheels with a wheel frame.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional buffer members are used to facilitate veer of the skateboard, then the skateboard can turn on even roadways, but it cannot slide on uneven roadways or stairs
Solution Approach 1:
The skateboard is divided into functionally independent segments: the base plate with its own buffering system, the truck assembly with independent buffering, and the wheel assembly. This segmentation allows each component to handle specific aspects of uneven terrain navigation, with the base plate buffer members (first, second, third buffer members) absorbing shocks from the ground while the truck buffer members (fourth, fifth buffer members) handle vibrations from the wheels independently.
Solution Approach 2:
Buffer members are introduced as intermediary elements between the skateboard components and the external environment. The base plate buffer members are disposed between the fastening levers and the through holes of the base plate, while the truck buffer members are disposed between the fastening levers and the through holes of the trucks, acting as mediators that absorb and dampen impacts and vibrations before they reach the structural components.
2Ease of manufacture
If the skateboard structure is simplified for easy manufacture, then production cost decreases, but the ability to handle uneven terrain is lost
Solution Approach 1:
The buffer members serve multiple functions simultaneously: they act as shock absorbers for uneven terrain, vibration dampers for smooth surfaces, and structural spacers to maintain proper component spacing. The fastening levers also serve dual purposes as both structural connectors and mounting points for the buffer members, reducing the need for separate components.
Solution Approach 2:
The buffering capability is achieved by changing the physical parameters of existing components rather than adding entirely new systems. The buffer members are designed with specific material properties (elasticity, damping characteristics) and geometric parameters (thickness, cross-sectional area) that allow them to provide adequate buffering for uneven terrain while being manufactured using standard processes compatible with the existing skateboard production line.

AI summary
A skateboard assembly is provided, including: a base plate having a plurality of first through holes, an ear part formed on the base plate, a second through hole formed on an end of the ear part corresponding to the base plate, a first stopping part formed on an inner periphery of the second through hole, and a protruding part formed on the base plate and having a first groove. The ear part and the protruding part are disposed on a same side of the base plate. The second through hole has a cross section orthogonal to the base plate. The skateboard assembly further comprises buffer members, retaining members, wheel frames, keels and plates, which are assembled and coupled together by a plurality of fastening members, such that the skateboard is assembled.
