Tension-Folding Packaging Material for Secure Object Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials do not effectively apply tension to securely hold and protect objects during packaging, particularly when combined with boxes.
Innovation Solution
A packaging material design featuring a first surface part with a bottom plate and a second surface part with a top plate, connected by a boundary line, where folding portions outside the rectangular shape allow for tension application, securing the object between the plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing packaging materials are used without tension application, then the packaging process is simple, but the object is not securely held or protected during packaging
Solution Approach 1:
The packaging material incorporates folding portions that can be dynamically adjusted to apply tension to the object. The structure transitions from a static flat state to a dynamic folded state, where the folding portions create tension forces that securely hold the object between the bottom plate and top plate without requiring complex external fastening mechanisms
Solution Approach 2:
The packaging material is designed to self-secure the object through its own structural features. The folding portions inherently generate tension when folded, and the engagement features automatically lock the structure in place, eliminating the need for separate fastening devices or complex assembly procedures
2Reliability
If folding portions are added to apply tension, then the object is securely held, but the manufacturing complexity increases
Solution Approach 1:
The packaging material is divided into distinct functional segments: a bottom plate, a top plate, and intermediate folding portions with engagement features. This segmentation allows each part to be optimized for its specific function while maintaining ease of manufacture through standardized cutting and folding patterns that can be efficiently produced using conventional packaging material manufacturing processes
3Loss of substance
If rectangular plates with folding portions are used, then material waste is minimized, but the tension application mechanism becomes more complex
Solution Approach 1:
The folding portions serve multiple functions simultaneously: they provide tension application, create structural support, enable the transition from flat to three-dimensional form, and incorporate engagement features for self-securing. This multi-functionality eliminates the need for separate components, reducing overall structural complexity while minimizing material waste through efficient use of the rectangular plate geometry

AI summary
A packaging material includes a first surface part that is adjacent to one side of a boundary line and has a bottom plate on which an object to be packaged is placed, and a second surface part that is adjacent to the other side of the boundary line and has a top plate that holds and wraps the object to be packaged with the bottom plate in a state of being folded along the boundary line, the boundary line being interposed between the first surface part and the second surface part, in which the bottom plate and the top plate are rectangular regions where one corner of the bottom plate and one corner of the top plate are in contact with each other at the boundary line, and portions of the first surface part and the second surface part, which are located outside four sides of a rectangular shape of the bottom plate and the top plate, are folding portions that are foldable at the four sides.
