Solution Overview

Problem

There is a need for secure and versatile carriers for miniature baby dolls that can be attached to children's backpacks, as existing doll carriers do not provide adequate transportation solutions for these small dolls.

Innovation Solution

A doll carrier system comprising an elastic housing with a slit that can change dimensions from a relaxed to a compressed state, allowing the doll to be securely stored and easily transported, with features like a curved shape, elastomeric material, and attachment options to backpacks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the housing is made rigid to protect the doll, then protection is improved, but adaptability to different storage spaces deteriorates

Engineering Contradiction:

ImproveprotectionVSAvoidadaptability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The housing is made from elastomeric material that provides protection while remaining flexible to adapt to different storage spaces and compression states, resolving the contradiction between rigid protection and adaptability

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The housing can transition between compressed and relaxed states, allowing it to adapt to different storage conditions while maintaining protection when needed, balancing rigidity and flexibility

Inventive Principle:

Principle #15Dynamics

2Volume of moving object

If the housing is made compressible to save space, then volume is reduced, but structural strength deteriorates

Engineering Contradiction:

ImprovevolumeVSAvoidstructural strength

Core Design Contradiction:

Volume of moving objectVSStrength

Solution Approach 1:

The elastomeric housing provides structural strength even in compressed state, allowing volume reduction without sacrificing protection

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The elastomeric material inherently provides cushioning and protection during compression and transition, preventing damage to the doll while enabling space-saving compression

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If the slit is made larger to facilitate doll insertion, then ease of operation is improved, but security of doll retention deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The slit dynamically adjusts its opening during insertion and then closes to secure the doll, providing both ease of operation and security retention

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The housing automatically closes the slit after doll insertion through elastic recovery, providing security without requiring additional fastening actions

Inventive Principle:

Principle #25Self-service

AI summary

A doll carrier is described. The doll carrier may include an elastic housing with a longitudinal slit and the width of the slit may be configured to expand widthwise upon pressing upon the top and bottom of the housing. The doll carrier may further include a clip allowing the carrier to be clipped to a backpack or another substrate.
