Transforming Toy Shell Structure for Egg-to-Doll Shape Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toys that transform from an egg form to a bird form, such as described in Patent Literature 1, lack interest and fun due to a simple configuration.
Innovation Solution
A toy that can transform into a first egg-shaped form and a second doll-shaped form, featuring rotatable first and second sub-parts that form a continuous outer shell, with the first sub-parts and second sub-parts constituting the outer shell at both ends of the egg shape, and including a connecting portion with different hardness resin members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the toy uses a simple turning-over configuration to transform from egg form to bird form, then the manufacturing complexity is low, but the entertainment value and趣味性 are insufficient
Solution Approach 1:
The toy is divided into multiple separable components: an outer shell that can be opened, inner components including a doll figure, and transformation mechanisms. This segmentation allows the toy to transform between egg form and doll form while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The toy incorporates dynamic transformation mechanisms where the outer shell can rotate and open, and internal components can move relative to each other. This dynamic design enables the toy to change from a static egg shape to an accessible doll form, enhancing entertainment value without significantly increasing manufacturing complexity.
2Ease of manufacture
If the toy uses a single-piece outer shell structure, then the manufacturing process is simple, but the durability and resistance to breakage are reduced
Solution Approach 1:
The outer shell is divided into multiple segments or pieces that can be connected through resilient connections. This segmentation allows each piece to be manufactured separately with simpler processes while the combined structure provides enhanced durability and breakage resistance through the distributed connection points.
Solution Approach 2:
The connection between shell segments uses resilient elements that can elastically deform under stress. This parameter change in connectivity (from rigid to resilient) maintains structural integrity and durability while allowing the manufacturing process to remain relatively simple through standard connection techniques.
3Reliability
If the toy uses resilient connections between components, then the durability and breakage resistance are improved, but the device complexity increases
Solution Approach 1:
Resilient connections are implemented through elastic deformable portions within the shell structure itself, rather than adding separate complex mechanical components. The shell material or structure is designed to elastically deform at connection points, providing breakage resistance while maintaining relatively simple device architecture.
Solution Approach 2:
The outer shell incorporates flexible or resilient portions that can elastically deform to absorb shocks and prevent breakage. This use of flexible shell characteristics provides enhanced durability without requiring complex internal mechanisms, maintaining device simplicity while improving reliability.
