Side Opening Luggage with Segmented Internal Skeleton
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage designs with front-side openings require folding of garments, leading to wrinkles and inefficient storage, and three-sided openings have insufficient structural support and are heavy due to C-shaped frame plates.
Innovation Solution
A side opening, side hanging luggage with a lightweight internal skeleton and triangle zipper bags, allowing garments to be placed laterally without folding, featuring a zip fastener for quick access and supported by a robust internal frame structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a three-sided opening structure is used to facilitate garment storage, then ease of operation is improved, but structural strength deteriorates due to C-shaped frame plates
Solution Approach 1:
The internal frame structure is divided into multiple separate components (front frame plate, back frame plate, side frame plates) instead of using a single C-shaped frame plate. This segmentation allows each frame plate to be optimized independently for strength while reducing overall weight and material usage.
Solution Approach 2:
The heavy C-shaped frame plate structure is extracted and replaced with a lighter internal skeleton system consisting of multiple smaller frame plates connected together. This extraction removes the unnecessary weight while maintaining the required structural support for the three-sided opening.
2Strength
If a C-shaped one piece frame plate is used to provide structural support, then strength is improved, but weight increases
Solution Approach 1:
The single C-shaped frame plate is segmented into multiple smaller frame plates (front, back, and side frame plates) that are connected to form the internal skeleton. This segmentation reduces the total weight while maintaining structural support through distributed framing.
Solution Approach 2:
The internal skeleton uses thin frame plates instead of a heavy solid C-shaped structure. These thin frame plates provide sufficient structural support while minimizing weight, effectively replacing the bulky one-piece frame plate.
3Ease of operation
If a long zip fastener is used to mate with three-sided opening leads, then ease of operation is improved, but loss of time increases due to labor-intensive operation
Solution Approach 1:
The long zip fastener is divided into multiple shorter zip fasteners, each associated with a specific frame plate (front, back, or side frame plates). This segmentation allows the user to open only the necessary portion rather than the entire long zipper, significantly reducing the time and effort required.
Solution Approach 2:
Instead of requiring the user to open the entire long zip fastener, the segmented design allows partial action - opening only the specific frame plate area needed for access. This reduces the excessive action of opening the complete long zipper while maintaining full access capability.
