Multi-Material Skateboard Deck With Composite Outer Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skateboard decks are unnecessarily heavy due to their construction with multiple layers of maple wood, which have a low strength-to-weight ratio, and fiber-reinforced polymer layers are limited to internal use, failing to provide lightweight, durable, and stress-absorbing outer layers.
Innovation Solution
A multi-material skateboard deck construction featuring fiber-reinforced polymeric material as outer layers, combined with resilient layers, to create a lightweight, durable, and stress-absorbing structure using lamination and pressing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple layers of maple wood are used to construct the skateboard deck, then structural integrity is maintained, but the weight of the deck increases unnecessarily
Solution Approach 1:
The patent applies composite materials by combining fiber-reinforced polymeric material (such as carbon fiber, glass fiber, or aramid fiber reinforced polymer) with traditional wood layers to create a multi-material deck construction. The fiber-reinforced polymer layers provide high strength-to-weight ratio, allowing the deck to maintain structural integrity while significantly reducing overall weight compared to traditional all-wood construction.
2Reliability
If fiber-reinforced polymer layers are used as internal layers only, then wear control is maintained, but the deck weight reduction and stress absorption capability are limited
Solution Approach 1:
The patent inverts the conventional approach by placing fiber-reinforced polymer layers as the outer top and bottom layers of the deck instead of limiting them to internal layers only. This inversion allows the high-strength, lightweight material to be positioned where it can most effectively absorb stress and provide structural support during tricks and landings, while also enabling greater weight reduction throughout the entire deck structure.
3Ease of manufacture
If traditional wood layers are used, then manufacturing simplicity is maintained, but the strength-to-weight ratio is insufficient
Solution Approach 1:
The patent combines traditional wood layers with fiber-reinforced polymeric material layers in a composite construction. The wood layers (such as maple) provide traditional manufacturing benefits including ease of lamination and proven durability, while the fiber-reinforced polymer layers contribute high strength-to-weight ratio. This composite approach maintains relative manufacturing simplicity through established lamination processes while dramatically improving the strength-to-weight characteristics of the deck.
