Solution Overview

Problem

Existing expandable accordion-type toys lack imaginative play value beyond simple expansion and contraction.

Innovation Solution

An expandable accordion-type toy with a nesting shell design featuring interconnected accordion pop tubes that allow selective expansion and contraction, with each component nesting within another to form a figurine-like structure, enhancing imaginative play.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If simple expandable accordion tubes are used, then the toy can expand and contract easily, but the imaginative play value is limited

Engineering Contradiction:

Improveexpansion and contraction capabilityVSAvoidimaginative play value

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies nesting by placing multiple accordion components inside a shell structure that forms a figurine. The accordion tubes are nested within the shell, allowing the toy to transform between compact and expanded states while maintaining the figurine shape, thereby enhancing imaginative play value without compromising ease of operation

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent implements dynamics by making the accordion components movable and transformable within the shell. The ability of the accordion tubes to expand and contract dynamically allows the toy to change its configuration, providing varied play experiences and improving imaginative play value while maintaining operational simplicity

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple expandable components are added to enhance play value, then imaginative play is improved, but the device complexity increases

Engineering Contradiction:

Improveimaginative play valueVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent reduces device complexity by nesting multiple accordion components within a single shell structure. Instead of requiring separate housings for each accordion component, they are all contained within one figurine shell, simplifying the overall device structure while maintaining multiple expandable elements for enhanced play value

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent combines multiple functional components (multiple accordion tubes and shell structure) into a single integrated toy unit. The shell serves as both the housing and the figurine structure, while containing multiple accordion components, thereby reducing the number of separate parts and simplifying the device

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Described is an expandable accordion-type toy with a nesting shell that allows the toy to selectively expand and contract. The toy includes a top shell and a first expandable component connected to the top shell. A bottom shell is connected to a second expandable component. A center shell connects the first expandable component to the second expandable. Each of the first and second expandable components are made of accordion pop tubes to selectively transition between a contracted state and an expanded state. When in the contracted state, the first expendable component is concealed within the top shell and center shell, while the second expandable component is concealed within the center shell and bottom shell.
