Convertible Luggage and Pram Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of transporting a pram through airport security and onto an aircraft while adhering to stringent cabin baggage rules is complicated, often requiring the pram to be collapsed or stored in the aircraft hold, causing delays and inconvenience for parents with young children.
Innovation Solution
A luggage apparatus designed as a cabin-sized suitcase that converts into a pram, featuring a moveable portion that pivots to form a child seat, with integrated storage compartments and a hinge system allowing it to be stowed and deployed without needing to be emptied, thus complying with size restrictions and eliminating the need for separate pram storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate pram is used for transporting children through the airport, then the child can be comfortably transported, but the pram must be stored in the aircraft hold causing delays and inconvenience
Solution Approach 1:
The patent combines the pram and suitcase into a single integrated apparatus. The pram components (seat, backrest, footrest) are stored within the suitcase body and deployed when needed, eliminating the need for separate pram storage at the destination while maintaining child transport functionality throughout the journey
Solution Approach 2:
The apparatus serves multiple functions: it operates as a compact suitcase for storing travel items, transforms into a functional pram for transporting children through the airport, and can be taken directly onto the aircraft cabin. This multi-functionality resolves the contradiction by making the same device useful in all phases of travel without requiring separate storage
2Reliability
If the pram is collapsed to pass through security, then it can be x-rayed, but the pram must be emptied and reassembled causing delays
Solution Approach 1:
The pram is divided into separable components (seat, backrest, footrest) that are stored in different compartments within the suitcase. During security screening, the entire compact suitcase passes through x-ray without disassembly. After screening, the components are quickly reassembled by removing dividers and connecting parts, significantly reducing the time required compared to collapsing a traditional pram
3Ease of operation
If the luggage is made to comply with cabin baggage size restrictions, then it can be taken onto the plane, but the storage capacity is reduced
Solution Approach 1:
The patent utilizes the third dimension (vertical space) by incorporating compartments throughout the suitcase body including top, bottom, and side compartments. The pram components are stored vertically within the suitcase structure rather than requiring horizontal expansion. Multiple access points (top, bottom, side) allow retrieval of items from different compartments without requiring the luggage to be opened from a single location, maintaining ease of access despite compact dimensions
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
Enables parents to carry their child's pram onto the plane without separate storage, reducing delays and increasing storage utility with multiple access points and a stable, secure seating arrangement for the child.
Implementation Method 1
The moveable portion may pivot with respect to the fixed portion around a hinge.

AI summary
A luggage apparatus is described. The luggage apparatus comprises an apparatus body haying a moveable portion and a fixed portion, the moveable portion being movable with respect to the fixed portion between a deployed position and a stowed position. In the deployed position, a moveable portion surface and a fixed portion surface are arranged to define a seat for a child and in the stowed position, the moveable and fixed portion surfaces are substantially contained within the luggage apparatus body.
