Foldable Carrying Handle for Corrugated Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corrugated boxes with handles require partial collapse and reassembly during transportation, which is time-consuming and inefficient.
Innovation Solution
A container design featuring a foldable carrying handle that can be easily rotated and locked, allowing for secure carrying and efficient stacking, formed from a single corrugated box blank with scorelines for easy collapse and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handles are added to corrugated boxes for easy carrying, then ease of operation is improved, but device complexity increases and time is lost during collapse and reassembly operations
Solution Approach 1:
The handle is merged with the container body as a single integrated structure formed from the same corrugated board, eliminating the need for separate handle components and reducing assembly steps. The handle folds flat against the container walls when not in use, combining carrying function with compact storage without requiring separate collapse operations.
Solution Approach 2:
The handle is designed with dynamic folding capability, allowing it to transition between extended carrying position and folded storage position. The handle can be folded along with the container walls when collapse is needed, and unfolded when carrying is required, providing adaptability without permanent structural complexity.
2Volume of moving object
If handles are made foldable to reduce storage space, then volume is reduced, but device complexity increases due to additional folding mechanisms
Solution Approach 1:
The handle folding mechanism is merged with the container wall folding structure. Both the handle and container walls fold along the same crease lines and using the same folding motion, eliminating the need for separate handle folding mechanisms and reducing overall structural complexity.
Solution Approach 2:
The handle is segmented into multiple sections that can fold independently along defined crease lines, allowing compact storage while maintaining simplicity. The handle sections are designed to fold flat against the container walls without requiring complex locking or securing mechanisms.
3Reliability
If handles are designed to be secure and stable during carrying, then reliability is improved, but ease of operation decreases due to difficulty in folding and unfolding
Solution Approach 1:
The handle is designed with dynamic flexibility, allowing it to be easily folded and unfolded through simple bending motions along crease lines. The handle provides stable support during carrying when unfolded, and can be quickly collapsed when not in use, balancing reliability with ease of operation through its flexible, adaptable nature.
Solution Approach 2:
The handle is designed to self-support during carrying without requiring additional fastening mechanisms. The handle's structure naturally maintains its shape and provides stable support through its own form, eliminating the need for complex locking mechanisms while maintaining reliability during use.

AI summary
A container configured to hold one or more items for transportation. The container can comprise: a base; two opposing end walls; two opposing sidewalls; and a lid. The opposing side walls each can comprise a side flap with an opening. The lid can comprise two opposing top panels and two handle flaps. Each of the two opposing top panels can be foldably coupled to a different one of the two opposing end walls. Each of the two handle flaps can be foldably coupled to a different one of the two opposing top panels. When the container is in a closed configuration, a handle can be formed by the two handle flaps and comprise two engagement end tabs located at two opposing ends of the handle. The handle can be removably coupled to the side flaps by the engagement end tabs engaging with the openings of the side flaps. The handle can be configured to be rotatable while the engagement end tabs remain engaged with the openings of the side flaps. Other embodiments are disclosed.
