Packing Box Handle Design for Automation and Load Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing boxes have weak load-resistance due to manually assembled handles, which limits their automation manufacturing process and efficiency in supporting weight during transportation.
Innovation Solution
A packing box design featuring a top part with first to fourth upper paperboards that form a handle by folding and punching holes, allowing handle pieces to be rotated and erected for improved load-resistance, and includes a buffer part and glue members for enhanced stability and separation prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a handle is manually assembled by inserting synthetic resin handle pieces into hanging holes, then the packing box can be completed with portability features, but the automation process cannot be achieved and manual labor is required
Solution Approach 1:
The handle pieces are designed to automatically form the handle structure through punching holes that allow them to be folded and erected by themselves during the automation process, eliminating the need for manual insertion into hanging holes
Solution Approach 2:
The handle pieces are pre-formed on the upper paperboards with punching holes positioned in advance, allowing them to be automatically folded and erected during the packaging process without requiring subsequent manual assembly operations
2Strength
If handle pieces are spaced apart on the upper paperboard to secure load-resistance, then the handle structure can support weight, but the handle pieces are partially spaced when erected resulting in weak load-resistance
Solution Approach 1:
The handle pieces are arranged and folded in a three-dimensional configuration where they overlap and interlock vertically through the punching holes, transforming the two-dimensional spacing problem into a three-dimensional interlocking structure that provides both strength and stability
Solution Approach 2:
The handle pieces are designed to nest within each other when folded and erected, with one handle piece fitting into the structure formed by another, creating a compact and stable handle assembly that maximizes load-resistance while minimizing spacing

AI summary
A packing box includes first and second sidewall parts spaced apart and facing each other, first and second connecting parts, a third connecting part attaching the second connecting part to the first sidewall part, a bottom part connecting lower portions of the first and second sidewall parts and the first and second connecting parts, and a top part facing the bottom part and connecting upper portions of the first and second sidewall parts and the first and second connecting parts to form a receiving space. The top part includes first to fourth upper paperboards folded and extended from the upper portions of the first and second sidewall parts and the first and second connecting parts to form a handle, and a fifth upper paperboard folded from the third connecting part and disposed under the first to fourth upper paperboards to prevent withdrawal of contents from the receiving space.
