Portable Storage Container Strap Closure and Carry Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable storage bins often require two hands to carry, lack secure closure options, and have detachable straps that can get lost or serve no purpose, with lids not integrated for dual functionality.
Innovation Solution
A portable storage container with a flexible strap that doubles as a carry handle and secure closure, featuring swiveling affixers and mechanical fasteners for adjustable length, allowing single-handed carrying and secure lid attachment, and a lid that serves as a shallow tray for organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central handle is integrated into the container, then single-handed carrying is enabled, but the storage area is partially occluded reducing storage utility
Solution Approach 1:
The handle function is segmented from the main container body and relocated to the lid. The lid itself serves as the handle when carried, eliminating the need for a separate central handle that would occupy storage space. This segmentation allows the storage area to remain fully open while still providing single-handed carrying capability.
Solution Approach 2:
The lid serves multiple functions: it covers the storage area, provides a carrying handle when the container is transported, and works with the strap system for secure closure. This multi-functionality eliminates the need for separate dedicated handle structures that would reduce storage volume.
2Reliability
If additional locking devices are used for secure closure, then security is improved, but device complexity increases
Solution Approach 1:
The closure and carrying functions are merged into a single strap system. The same flexible strap that secures the lid to the container body also serves as the carrying handle when extended. This eliminates the need for separate locking devices and handles, reducing overall device complexity while maintaining security.
Solution Approach 2:
The flexible strap performs multiple functions: securing the lid in closed position, providing carrying capability when extended, and potentially serving as a attachment point for additional items. This multi-functional design achieves secure closure without adding complex locking mechanisms.
3Adaptability or versatility
If detachable straps are used for carrying, then carrying flexibility is improved, but the straps may separate and be lost
Solution Approach 1:
The carrying strap is merged with the closure strap into a single continuous flexible strap system. The strap is attached at both ends to the container body, forming a closed loop that cannot be accidentally lost. When the container is carried, the strap naturally extends to provide handling capability while remaining securely attached to the container structure.
4Ease of operation
If the lid is not integrated with the container body, then carrying with single hand is enabled, but the lid may get lost or set aside
Solution Approach 1:
The lid and container body are connected through the strap system that secures the lid in place. The same strap that provides carrying capability also functions as a retention mechanism, making it difficult to accidentally separate the lid from the container body. The strap creates a mechanical connection that maintains lid retention while allowing easy removal when needed.

AI summary
A portable storage container with a lid that is removably positionable on the top of the container body and defines indents or grooves on opposite sides, is described. A strap is secured to opposing side walls of the container body and extends through the side indents to secure the lid on the top of the container body. The top of the container body may also define side indents/grooves that align with the side indents of the lid to provide a snug fit of the strap on top of the lid. The strap may also be moved to a bottom depression or groove on the underside of the bottom of the container body.
