Segmented Plastic Tape Bundling for Secure Stacked Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bundled objects face issues where they are either not strongly enough bundled for transport or storage, leading to loosening during handling, or they are difficult to release when needed for use.
Innovation Solution
A bundled object configuration using a plastic tape that winds around the articles, with overlapping ends welded at intervals, allowing for strong bundling while maintaining ease of release by tearing at specific portions, and a bundling method involving tensile stress application and heat block welding to secure the tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging band ends are joined together to enable easy tearing, then the bundling can be easily released, but the joining may come off during transport causing loosening
Solution Approach 1:
The packaging band is divided into multiple segments with welded portions and non-welded portions alternately arranged. The welded portions provide secure joining while the non-welded portions allow for controlled tearing. This segmentation enables the band to maintain strength during transport while allowing easy release at designated locations.
Solution Approach 2:
Different portions of the packaging band have different properties: welded portions provide high strength and security, while non-welded portions provide ease of tearing. This local differentiation of properties allows the same band to simultaneously ensure bundling security and enable easy release when needed.
2Reliability
If the band film is welded at both ends to prevent loosening, then the bundling security is improved, but the ease of release deteriorates
Solution Approach 1:
The packaging band is segmented into multiple welded and non-welded portions. The welded portions prevent loosening during transport, while the non-welded portions serve as controlled weak points that allow easy tearing for release. This segmentation resolves the contradiction between security and ease of release.
Solution Approach 2:
The packaging band is pre-configured with non-welded portions at specific locations during manufacturing. These pre-positioned non-welded sections act as predetermined tear points that enable easy release without requiring forceful tearing, thus maintaining both security during transport and ease of release when needed.
3Ease of operation
If a simple packaging band is used for easy tearing, then the ease of release is improved, but the bundling strength is insufficient
Solution Approach 1:
The packaging band is segmented into alternating welded and non-welded portions. The welded portions provide the necessary bundling strength and prevent loosening, while the non-welded portions provide controlled weak points for easy tearing. This segmentation allows the band to simultaneously achieve both strength and ease of release.
Solution Approach 2:
Different sections of the packaging band have different structural qualities: welded portions are strong and secure, while non-welded portions are designed for easy tearing. This local differentiation enables the band to provide sufficient bundling strength where needed while maintaining ease of release at designated locations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a strong and secure bundling that prevents loosening during transport while allowing for efficient release by tearing at designated points, ensuring the articles can be easily unpacked when required.
Implementation Method 1
the superimposed portions are welded to each other at a plurality of places arranged at intervals from each other in a tape width direction, at end portions on the body-to-be-bundled side

AI summary
A bundled object is obtained in which a plurality of overlapped articles is sufficiently strongly bundled and it is also easy to release the bundling. A bundled object 1 is configured to include a body-to-be-bundled 3 which is made by overlapping a plurality of articles 2 and has four marginal portions 3a each extending a direction orthogonal to an overlapping direction, and a strip-shaped plastic tape 4 which bundles the body-to-be-bundled 3 by winding around the body-to-be-bundled 3 once so as to pass over the four marginal portions 3a. Then, both end portions 4a and 4b other than a winding portion of the plastic tape 4 are overlapped on each other at a position away from the body-to-be-bundled 3 and close to one marginal portion 3a, and the overlapped tape both end portions 4a and 4b are welded to each other at a plurality of welded portions H.
