Skateboard Rack with Rounded Protrusions for Wall Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skateboard racks either damage walls due to wheel contact or increase manufacturing costs and safety hazards with complex designs.
Innovation Solution
A one-piece rack with a series of rounded protrusions extending from a rear support, allowing skateboards and accessories to be mounted without wall contact, featuring angled protrusions for safe positioning and optional locking mechanisms for theft protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional skateboard racks with horizontal bars and vertical posts are used, then skateboards can be held securely, but the lower wheels contact the wall causing damage to the wall
Solution Approach 1:
The rack uses rounded protrusions instead of straight horizontal bars. These curved surfaces naturally guide the skateboard wheels away from the wall, preventing wall contact while maintaining secure holding. The rounded geometry provides a self-aligning mechanism that keeps wheels positioned safely away from the wall surface.
Solution Approach 2:
The invention transitions from a two-dimensional horizontal bar structure to a three-dimensional protrusion array. By adding vertical height and curvature to the support elements, the rack creates a new spatial dimension that allows wheels to rest on elevated rounded surfaces rather than flat horizontal bars, thereby preventing wall contact.
2Object-affected harmful factors
If arched spacer arms are added below hooks to contact the board and maintain it away from the wall, then wall damage is prevented, but manufacturing costs increase and additional space is required
Solution Approach 1:
The rack merges the support function and the wall-protection function into a single integrated protrusion structure. The rounded protrusions simultaneously hold the skateboard wheels and position them away from the wall, eliminating the need for separate spacer arms. This consolidation reduces manufacturing complexity and material requirements.
Solution Approach 2:
The rounded protrusions serve multiple functions: they support the weight of the skateboard, prevent wall contact, and provide a secure resting position for the wheels. This multi-functional design replaces the need for specialized components like arched spacer arms, simplifying the overall structure.
3Object-affected harmful factors
If arched spacer arms are used to maintain boards away from the wall, then wall damage is prevented, but safety hazards increase for individuals who may bump or fall against the rack
Solution Approach 1:
The rounded protrusions have smooth curved surfaces that are less likely to cause injury compared to sharp or angular spacer arms. The spherical geometry distributes contact forces more evenly and reduces the risk of harm to individuals who may accidentally bump or fall against the rack.
4Device complexity
If a one-piece construction with rounded protrusions is used, then manufacturing costs are reduced and safety is improved, but the ability to provide varied locking combinations is limited
Solution Approach 1:
The rack incorporates segmented locking arms that can independently rotate and engage with skateboard components. These modular locking segments provide multiple positioning options and locking combinations while maintaining the overall simplicity of the one-piece construction. The segmented design allows for varied locking configurations without requiring complex manufacturing processes.

AI summary
A rack to hold skateboards, longboards, scooters, motorcycle helmets, purses, umbrellas and other implements or accessories. The rack is adapted to be mounted on a wall or surface. The rack is formed of a lip extending from a rear support. The lip is formed of a series of rounded protrusions. Items to be held by the rack can be received over the protrusions. In one embodiment, each protrusion is angled at a predetermined angle from the front. This helps keep a received skateboard, scooter or other accessory at an appropriate angle such that the wheels or surface of the accessory will remain off an affixed wall to avoid damage to wall. The rack can also include a locking mechanism for locking adjacent protrusions. The rack is designed for safety by having rounded edges on all areas that protrude from the wall.
