Luggage Case Foldable Expansion Sleeve Separation Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Luggage cases for commercial airplanes often face size limitations, making it cumbersome and costly to bring multiple cases to meet varying travel needs, as they may be too small for one trip and insufficient for another.
Innovation Solution
A luggage case with a first portion for under-seat storage and a foldable, expandable second portion that transforms between configurations, featuring expandable sleeves, a separation member, and an extendable handle system to accommodate both carry-on and under-seat requirements without adding extra components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a luggage case is designed to be large enough for carry-on storage, then it provides sufficient storage space for returning trips, but it cannot be stored underneath the seat during outbound travel
Solution Approach 1:
The patent applies a foldable portion that can dynamically change configuration between folded and expanded states. The foldable portion includes expandable sleeves that can be extended to increase storage volume when needed and folded back when compact size is required, allowing the luggage case to adapt to different storage requirements for outbound and returning trips
Solution Approach 2:
The luggage case is divided into a first portion (rigid base structure) and a second foldable portion (expandable storage section). This segmentation allows the foldable portion to be independently manipulated - expanded when additional storage is needed for returning trips, and folded when under-seat storage is required for outbound travel
2Adaptability or versatility
If a luggage case is designed to be compact for under-seat storage, then it fits in limited airline luggage spaces, but it is too small for returning trip storage needs
Solution Approach 1:
The foldable portion with expandable sleeves provides dynamic volume adjustment capability. When the sleeves are folded back, the luggage case maintains a compact profile suitable for under-seat storage during outbound travel. When the sleeves are extended, the storage volume increases to meet the requirements for returning trips
Solution Approach 2:
The expandable sleeves are designed to nest within the foldable portion when collapsed. This nesting mechanism allows the sleeves to be stored within the existing structure without adding to the overall footprint, enabling the luggage case to maintain compact dimensions for under-seat storage while providing expandable capacity when needed
3Volume of moving object
If multiple luggage cases are brought to meet varying travel needs, then storage space requirements are satisfied, but it becomes cumbersome and costly
Solution Approach 1:
The luggage case is designed with multi-functionality to serve dual purposes: as a compact under-seat bag for outbound travel and as a larger carry-on for returning trips. The foldable portion with expandable sleeves enables a single case to fulfill the storage requirements that previously necessitated multiple separate luggage pieces
Solution Approach 2:
The invention combines the functionality of two separate luggage cases (a compact under-seat bag and a larger carry-on) into a single integrated case. The foldable portion merges with the first portion to form a unified structure that can transition between compact and expanded configurations, eliminating the need to manage multiple separate luggage items
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 convenient transformation between under-seat and carry-on configurations, optimizing storage space and handling without increasing the luggage case's footprint, thus addressing the need for versatility in limited airline luggage spaces.
Implementation Method 1
an elastic handle connected to the second foldable portion and configured to accommodate the extendable handle bar such that when the second foldable portion is in the expanded configuration the elastic handle presses the extendable handle against the second foldable portion
Data Source
AI summary
Provided herein is a luggage case having a first portion having a storage space, a second foldable portion having at least one expandable sleeve for transforming between a folded configuration and an expanded configuration, a separation member positioned between the first portion and the second foldable portion, the separation member separating the first and second portions such that when the second foldable portion is in the folded configuration the separation member prevents the second foldable portion from take away any storage space from the first portion. The luggage case may further have an extendable handle bar having at least one extendable bar, the extendable handle bar being connected to the first portion for pulling the luggage case, and an elastic handle connected to the second foldable portion and configured to accommodate the extendable handle bar such that when the second foldable portion is in the expanded configuration the elastic handle presses the extendable handle against the second foldable portion.
