Plush Bouncing Ball Structure Preserving Bounce Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plush toys do not bounce effectively, while conventional bouncing balls lack a soft and cuddly exterior, failing to provide a fun and engaging experience.
Innovation Solution
A bouncing ball toy with a plush fabric exterior is designed over an internal resilient ball structure, ensuring the plush exterior does not significantly dampen the bounce, using highly resilient materials like polyurethane and careful attachment techniques to maintain liveliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plush fabric exterior is added to a bouncing ball, then the toy becomes soft and cuddly, but the bounce performance is significantly dampened
Solution Approach 1:
The bouncing ball is segmented into two distinct functional layers: an internal resilient core structure that provides bounce performance, and an external plush fabric layer that provides softness. This segmentation allows each layer to independently fulfill its specific function without compromising the other.
Solution Approach 2:
The plush fabric exterior is nested over the internal resilient ball structure, creating a layered configuration where the softer outer layer contains the harder inner core. This nesting arrangement allows the plush exterior to provide cuddliness while the inner core maintains bounce capability.
2Ease of manufacture
If conventional plush toys are made with stuffing material, then they are soft and tossable, but they do not bounce meaningfully
Solution Approach 1:
The internal ball structure uses highly resilient materials with specific elastic properties that enable meaningful bounce. By carefully selecting and tuning the material parameters of the inner core, the toy achieves sufficient bounce performance while the outer plush layer maintains softness for cuddliness.
3Reliability
If a smooth and hard exterior is used for a bouncing ball, then it provides high bounce, but the exterior is plain and less engaging
Solution Approach 1:
Different parts of the bouncing ball have different qualities: the internal core has hard, resilient properties optimized for bounce, while the external surface has soft, plush properties optimized for tactile appeal and visual engagement. This local differentiation of material properties resolves the contradiction between performance and appeal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bouncing ball toy offers a fun and engaging experience with both soft, cuddly plush exterior and significant bounce, maintaining 50-75% of the internal ball's bounce height even with the plush cover.
Implementation Method 1
The interior ball structure may comprise highly resilient materials and provide significant bounce and liveliness after impacting a hard object
Data Source
AI summary
The present application relates to a toy comprising an internal ball structure comprising a highly resilient material capable of significant bouncing off a hard surface, a plush fabric skin configured to cover the internal ball structure such that the plush fabric exterior does not significantly impact or dampen the ability of the internal bouncing ball structure to bounce when impacting a surface.
