Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pickleball paddles struggle to provide sufficient 'dwell time' and spin generation while conforming to USA Pickleball rigidity specifications, with current materials and designs failing to optimize impact energy absorption and angular momentum transfer.
Innovation Solution
A pickleball paddle design featuring a core portion with a reinforcing member oriented at non-perpendicular angles, a fiber-reinforced composite structure, and a grid-like grid structure that enhances core strength and flexibility, combined with a foam core for improved impact absorption and spin generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a traditional honeycomb core structure is used, then the paddle meets basic rigidity requirements, but the dwell time and spin generation are insufficient
Solution Approach 1:
The patent uses a composite core structure combining foam material with fiber-reinforced plies (carbon fiber, fiberglass, or other fibers) oriented at non-perpendicular angles. This composite approach provides both the flexibility needed for extended dwell time and the strength required to meet rigidity specifications, resolving the contradiction between softness and structural integrity.
Solution Approach 2:
The fiber reinforcement is strategically placed within the foam core at specific non-perpendicular angles to create localized stiffness where needed while maintaining overall core flexibility. This allows different regions of the core to have different mechanical properties, optimizing both dwell time and structural strength.
2Duration of action of moving object
If the core is made softer to increase dwell time, then spin generation improves, but the paddle rigidity decreases
Solution Approach 1:
The combination of foam core with angled fiber reinforcement creates a composite structure that exhibits both flexibility and rigidity. The foam provides cushioning and dwell time, while the fiber plies oriented at non-perpendicular angles provide structural stability, allowing the paddle to meet rigidity specifications while maintaining extended dwell time for spin generation.
Solution Approach 2:
The patent changes the orientation parameter of the fiber reinforcement from perpendicular to non-perpendicular angles, fundamentally altering the mechanical properties of the core. This angular orientation allows the core to deform more during impact (increasing dwell time) while still maintaining overall rigidity through the distributed fiber network.
3Strength
If a reinforced core structure is added, then core strength and spin capability improve, but the device complexity increases
Solution Approach 1:
The core is segmented into multiple layers with different functions: the foam base material provides cushioning, while discrete fiber-reinforced plies provide structural strength. This segmentation allows each layer to be optimized independently and simplifies the manufacturing process compared to creating a fully integrated complex structure.
Solution Approach 2:
Rather than fundamentally redesigning the entire core structure, the patent modifies a key parameter of existing core construction by orienting fiber reinforcement at non-perpendicular angles. This parameter change achieves enhanced strength and spin capability while maintaining a relatively simple manufacturing process and core architecture.

AI summary
A pickleball paddle including a handle portion and a head portion is disclosed. The head portion is operably connected to the handle portion and includes a core portion, a first layer, a second layer, and a reinforcing member. The core portion defines an edge, a first surface, and a second surface. The first layer is disposed adjacent the first surface of the core portion and is made from a first material. The second layer is disposed adjacent the second surface of the core portion, is parallel to the first layer, and is made from the first material. The reinforcing member is disposed within the core portion and is in contact with the first layer and the second layer. A first section of the reinforcing member is oriented at a non-perpendicular angle relative to the first layer.
