Wrapping Tearing Device with Adhesive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for unwrapping packages, such as gift wrapping, result in random and imprecise tearing, causing frustration for young children, older adults, and individuals with disabilities, and lack a device for precise straight-line or personalized pattern tearing.
Innovation Solution
A wrapping tearing device comprising adhesive elongated strip layers with perforations and a tearing thread, allowing for precise tearing along a straight line or personalized pattern, facilitated by a pull tab mechanism for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hand tearing method is used, then ease of operation is maintained, but manufacturing precision (tear precision) deteriorates
Solution Approach 1:
The device segments the tearing function into multiple components: adhesive layers for positioning, perforations for tear initiation, and tearing threads for controlled separation. This segmentation enables precise tearing while keeping the overall device simple and easy to apply.
Solution Approach 2:
The device performs preliminary actions by pre-positioning adhesive layers and creating perforations before the actual tearing occurs. The tearing thread is pre-configured in a specific pattern, so when pulled, it automatically creates the desired tear path without requiring complex user manipulation.
2Measurement precision
If random tearing method is used, then device complexity is minimized, but measurement precision (tear pattern control) deteriorates
Solution Approach 1:
The device applies local quality by positioning adhesive layers and perforations at specific locations and orientations. The tearing thread is configured with a specific pattern (straight line, wavy line, or spiral) at particular positions, creating controlled tear patterns in specific areas while maintaining simplicity in the overall device structure.
3Ease of operation
If traditional unwrapping method is used, then ease of manufacture is maintained, but ease of operation for vulnerable groups deteriorates
Solution Approach 1:
The device enables self-service by automatically providing the tearing path through its design. When the tearing thread is pulled, the adhesive layers and perforations automatically align and separate the wrapping paper along the desired path, eliminating the need for users to manually find or create seams. This makes unwrapping accessible to young children, older adults, and those with disabilities.

AI summary
A device for easily unwrapping a package forming a personalized pattern in the paper is provided. The device includes a first adhesive elongated strip layer, comprising: a first and second horizontal elongated edges having first and second ends; and first and second vertical side edges extending between the first and second horizontal elongated edges. Further included is a second adhesive elongated strip layer separated from the first adhesive layer by a gap, the second adhesive layer elongated strip, comprising first and second horizontal elongated edges each having first and second ends and first and second vertical side edges extending between the horizontal elongated edges. A first non-adhesive strip layer placed over the gap, a tearing thread located on the first non-adhesive strip layer; and a second non-adhesive strip layer located on top of the tearing thread and the first non-adhesive strip layer.
