Cardboard Packaging Base and Lid Flaps for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging designs for free-flowing goods face instability under pressure loads, particularly when stacked, and complex dust flap structures hinder efficient automated production and filling processes.
Innovation Solution
A packaging design featuring base and lid flaps that rest on side walls and protrude beyond them, eliminating the need for complex dust flaps, allowing for secure closure, increased load stability, and simplified production and filling processes, using a one-piece blank with angled cutting lines and articulated sections for enhanced stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex dust flap structures are used to ensure secure closure and load stability, then closure security and load stability are improved, but automated production and filling processes become slower and more problematic
Solution Approach 1:
The packaging structure is divided into distinct functional elements: base flaps hinged to front/rear walls, lid flaps hinged to front/rear walls, and dust flaps hinged to side walls. This segmentation allows each element to perform its specific function independently, simplifying the overall structure while maintaining closure security and load stability.
Solution Approach 2:
Instead of using complex dust flap structures to achieve closure security, the invention inverts the approach by designing base and lid flaps that directly rest on and extend beyond the side walls. This inverted configuration achieves the same security function with a simpler structure that is more compatible with automated production.

If complex dust flap structures are used to ensure secure closure and load stability, then load stability is improved, but automated production and filling processes become slower and more problematic
Solution Approach 1:
The packaging structure is divided into distinct functional elements: base flaps hinged to front/rear walls, lid flaps hinged to front/rear walls, and dust flaps hinged to side walls. This segmentation allows each element to perform its specific function independently, simplifying the overall structure while maintaining closure security and load stability.
Solution Approach 2:
The base and lid flaps are designed with specific dimensional parameters that allow them to extend beyond the side walls by a defined distance. This parameter change enables the flaps to provide load stability through their extended configuration without requiring complex dust flap structures, thereby facilitating faster automated production.
3Stability of the object's composition
If base and lid flaps extend beyond side walls to provide load stability, then load stability is improved, but manufacturing complexity increases
Solution Approach 1:
The base and lid flaps serve multiple functions: they provide closure security by overlapping the side walls, enhance load stability by extending beyond the side walls, and facilitate automated production through their simplified hinge connection to front and rear walls. This multi-functionality reduces the need for separate complex dust flap structures.
Solution Approach 2:
Instead of using complex dust flap structures to achieve closure security, the invention inverts the approach by designing base and lid flaps that directly rest on and extend beyond the side walls. This inverted configuration achieves the same security function with a simpler structure that is more compatible with automated production.
