Solution Overview

Problem

Conventional pickleballs made from non-crosslinked polymers have a short lifespan, often cracking or losing stiffness after a few games, leading to inconsistent flight patterns and frequent replacements, which disrupt gameplay and increase costs.

Innovation Solution

The pickleballs are constructed with non-crosslinked polymers and treated with an electron beam to crosslink the polymer, forming a three-dimensional network structure that enhances durability and stiffness, using an absorbed dose of about two to four-hundred kilograys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional pickleballs are made from non-crosslinked polymers, then manufacturing is simpler and cost is lower, but durability and lifespan are significantly reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidball durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies electron beam irradiation to change the chemical structure of the polymer from non-crosslinked to crosslinked state. This parameter change in molecular structure transforms the material properties, achieving both improved durability and maintained manufacturability through a post-production treatment process

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite structure at the molecular level by forming crosslinks between polymer chains through electron beam treatment. This composite network structure within the polymer matrix provides enhanced mechanical strength and durability while maintaining the overall ball structure

Inventive Principle:

Principle #40Composite materials

2Quantity of substance

If conventional pickleballs are made from non-crosslinked polymers, then production cost is lower, but lifespan is only 1-2 games requiring frequent replacement

Engineering Contradiction:

Improveproduction costVSAvoidball lifespan

Core Design Contradiction:

Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The electron beam crosslinking treatment is applied as a preliminary action during or after manufacturing to permanently enhance the polymer structure. This pre-treatment ensures the ball achieves maximum durability before use, extending lifespan to 2.4-3.1 times longer without requiring frequent replacements

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By changing the polymer's molecular structure through electron beam-induced crosslinking, the patent fundamentally alters the material's degradation resistance. This parameter change in chemical structure directly extends the operational lifespan while maintaining cost-effectiveness through reduced replacement frequency

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If conventional pickleballs use non-crosslinked polymers, then manufacturing process is simpler, but flight consistency deteriorates due to cracking and deformation

Engineering Contradiction:

Improvemanufacturing process complexityVSAvoidflight pattern consistency

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The electron beam treatment changes the polymer's physical and chemical parameters, creating a crosslinked network that resists deformation and cracking. This parameter change ensures consistent flight patterns by maintaining structural integrity throughout the ball's extended lifespan

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical reinforcement methods with electron beam-induced chemical crosslinking. This substitution achieves enhanced structural stability and flight consistency through molecular-level bonding rather than mechanical strengthening, maintaining manufacturing simplicity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Particular embodiments described herein provide for a pickleball comprising a polymer outer shell, where at least a portion of the polymer outer shell is crosslinked. The pickleball with crosslinked material can be created by receiving manufactured non-crosslinked polymer pickleballs in consumer packaging in a bulk shipping container, removing the manufactured polymer pickleballs from the bulk shipping container, and passing the manufactured polymer pickleballs in the consumer packaging through an electronic beam to crosslink at least a portion of the polymer that comprises the pickleball to create the crosslinked polymer pickleballs.
