Non-Symmetric Tab Structures for Package Interlocking Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated package customization systems face challenges in providing sufficient options and customization for creating personalized packaging, particularly in ensuring precise interlocking of symmetric tab structures when converted into three-dimensional forms.
Innovation Solution
A system that converts symmetric tab structures to non-symmetric designs by defining cut lines and functional elements using polar coordinates based on pivot points, allowing for dynamic adjustment of tab dimensions and shapes to ensure proper interlocking during the folding process, thereby maintaining structural integrity and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If symmetric tab structures are used in package design, then manufacturing simplicity is improved, but interlocking precision deteriorates when converted to three-dimensional forms
Solution Approach 1:
The system automatically converts symmetric tab structures to asymmetric configurations when detecting pivot points in the package design. The tab dimensions are adjusted based on their position relative to the pivot point, creating non-uniform tab structures that compensate for folding geometry and achieve precise interlocking in the three-dimensional assembled package.
2Adaptability or versatility
If automated package customization systems provide increased customization options, then user choice is improved, but system complexity increases
Solution Approach 1:
The system performs automatic detection and conversion of tab structures to asymmetric designs without requiring user intervention. When the system identifies pivot points and tab structures in the package design, it automatically calculates and applies the necessary dimensional adjustments, eliminating the need for users to manually configure complex asymmetric geometries while still providing access to customization options.

AI summary
A package generation system creates a package definition file for creation of a package flat. The file includes dimensions for cut lines along which the package will be separated from a two dimensional substrate. The flat includes facets and functional elements that connect the facets. The system will identify a pair of the functional elements that have a connecting relationship. The first facet of the pair is a tab structure having a symmetric design, and the second facet of the pair is a receiving structure. If the tab structure and receiving structure are connected to cut lines that intersect at a pivot point, the system will convert the definition of the tab structure from the symmetric design to a non-symmetric design. It will save dimensions for the edges and functional elements in the package design file with the non-symmetric design.
