Portable Bag Handling Extensions and Inset Liner Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable bags with a 'pillow-case' configuration inefficiently utilize space and handle packages, especially when dealing with differently sized and shaped items, leading to suboptimal loading and handling.
Innovation Solution
A portable bag design featuring integrated handling openings and improved volumetric characteristics, including foldable surfaces, inset interior liners, and creases, allowing for better alignment and utilization of space, along with optional features like magnetic closures and handle extensions for enhanced handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional pillow-case configuration is used, then manufacturing simplicity is maintained, but space utilization efficiency deteriorates
Solution Approach 1:
The interior liner is segmented with multiple cavities that are inset relative to the exterior surfaces, creating distinct compartments that optimize space utilization for different package sizes and shapes while maintaining the overall bag structure
Solution Approach 2:
The invention transitions from a conventional two-dimensional pillow-case configuration to a three-dimensional structured design with inset cavities, creating depth and volume optimization that accommodates various package geometries more efficiently
2Device complexity
If no peripheral accessories are incorporated, then device complexity is reduced, but handling efficiency deteriorates
Solution Approach 1:
The handling openings are integrally defined on the exterior surfaces of the bag, merging the handling function directly into the bag structure rather than adding separate peripheral handles or accessories, thus maintaining simplicity while improving handling efficiency
3Device complexity
If V-shaped pocket configuration is used, then structural simplicity is maintained, but loading efficiency deteriorates
Solution Approach 1:
Different regions of the bag interior have different structural qualities through the inset cavities, allowing optimal accommodation of different package types and sizes in specific zones, thereby improving loading efficiency while maintaining overall structural simplicity
