Portable Bag Zipper Segmentation for Faster Item Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Travel, school, and lifestyle bags do not allow easy access to stored contents, often requiring users to fully unzip pockets and search blindly for items, especially when items move due to gravity and movement during transport.
Innovation Solution
Implementing various zipper configurations, including one perimeter zipper or a 3-zipper configuration with two side zippers and one front/middle zipper, allowing users to partially or fully unzip compartments for efficient storage and retrieval, combined with customizable internal shelves using hook and loop fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If items are stored deep within pockets or storage areas, then storage capacity is improved, but item retrieval becomes cumbersome and time-consuming
Solution Approach 1:
The bag is divided into multiple compartments with independent zipper access points. Each compartment can be opened separately without unzipping the entire bag, allowing users to quickly access specific items stored in different sections without disturbing other contents.
Solution Approach 2:
Multiple zipper configurations (side zippers, top zippers, front zippers) provide access to storage areas from different directions and dimensions. This allows users to reach items without fully opening the bag, reducing retrieval time while maintaining storage capacity.
2Adaptability or versatility
If items are stored in deep pockets, then storage organization is improved, but item location becomes difficult without blind searching
Solution Approach 1:
Storage space is segmented into multiple compartments with designated purposes. Each compartment has its own access point, allowing users to visually scan and locate items in specific sections without searching through the entire bag contents.
Solution Approach 2:
Transparent or mesh pocket materials serve as intermediaries between stored items and the user's line of sight. These materials allow visual detection of item locations and contents while maintaining organization and protection.
3Ease of operation
If multiple zipper configurations are implemented, then item accessibility is improved, but device complexity increases
Solution Approach 1:
Multiple zippers serve multiple functions: they provide independent access to different compartments, allow partial opening for quick retrieval, and can be configured in various patterns (side, top, front access). This multi-functionality justifies the increased complexity by significantly improving accessibility.
4Adaptability or versatility
If internal storage compartments are made removable, then storage flexibility is improved, but structural complexity increases
Solution Approach 1:
Internal storage compartments are designed with removable features using simple attachment mechanisms such as snap buttons, Velcro straps, or elastic bands. This allows the storage configuration to dynamically adapt to different user needs while maintaining relatively simple overall structure.
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 efficient storage and organization, ensuring items remain in place during transit, allowing easy access and retrieval without blind searching.
Implementation Method 1
The eyelet twist lock clasps and internal hook and loop fastener system applications allow the user the ability to securely affix the internal storage compartments to the interior of the PBL so that the storage compartments do not move during transit.
Implementation Method 2
Contents often move due to gravity and general movement during transport, making item retrieval even more difficult.

AI summary
The PBL can be constructed utilizing various zipper configurations: one perimeter zipper (A) FIG. 5) (claims 1c, 2, 3) or a 3-way zipper configuration FIG. 1, 2, 3, 4) (Claims 1a, b, c, 2, 3) located on the front exterior storage compartment of the PBL. The 3-way zipper configuration has two independent zippers, one on each side, that run the entire length of each side and top of the front exterior storage compartment. The third middle zipper divides the front compartment from top to bottom, equally dividing the front compartment in halves. The various zipper configurations allows the user to (partially) or fully unzip only the front compartment and independently access or remove either or both internal/external customizable storage compartments, allowing for efficient storage and organization as well as effective and efficient item retrieval.
