Spiral Cut Tissue Paper Stack for Compact Storage and Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pre-shredded tissue paper packaging is bulky due to air occupation, making storage and display challenging, and users find it difficult to crumple sheets for both decorative and cushioning purposes.
Innovation Solution
A stack of tissue paper sheets cut in a spiral pattern to form parallel, narrow strips that can be easily expanded to occupy more volume, with optional fasteners like staples or adhesives to bind the sheets, allowing for compact storage and easy expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-shredded tissue paper is packaged for storage, then it is ready for use as filler, but the packaging becomes voluminous and occupies excessive storage space
Solution Approach 1:
Multiple sheets of tissue paper are nested one on top of another in a compact stack, with each sheet containing spiral strips that are concentrically arranged. This nesting allows the filler to occupy minimal space during storage while maintaining the ability to expand to full volume during use.
Solution Approach 2:
The filler transitions from a static compact state during storage to a dynamic expanded state during use. The spiral strips are designed to be easily separated and expanded by the user, transforming the compact stack into a voluminous filling material that can cushion and decorate gifts.
2Strength
If tissue paper sheets are crumpled to provide cushioning, then adequate protection is achieved, but it is difficult to crumple sheets to meet both decorative and cushioning goals
Solution Approach 1:
Each sheet is divided into multiple spiral strips that are naturally separated by the spiral cut pattern. This segmentation eliminates the need for users to manually crumple or tear the paper, as the strips are already pre-divided and can be easily pulled apart and arranged for both cushioning and decorative purposes.
Solution Approach 2:
The tissue paper sheets are pre-cut into spiral strips during manufacturing, creating a configuration that naturally separates into cushioning segments. This preliminary action of cutting the spirals removes the difficulty of manual crumpling while maintaining the cushioning strength needed for gift protection.
3Quantity of substance
If entire sheets of tissue paper are used for packaging, then low cost and easy recycling are achieved, but the sheets occupy excessive volume in storage and display
Solution Approach 1:
Multiple sheets are nested in a compact stack with minimal air space between them, allowing a large quantity of tissue paper material to be stored in a small volume. The spiral strip configuration enables the nested sheets to maintain their compact form while preserving the full material quantity for future use.
Solution Approach 2:
The tissue paper is transformed from flat entire sheets into spiral strip configurations. This parameter change in shape and structure allows the same material quantity to occupy significantly less storage volume while maintaining the functional properties needed for gift wrapping and cushioning.

AI summary
An expandable package filler or ornament includes a stack of sheets, such as tissue paper, foil, etc. The stack is bound together, such as by a fastener. A generally spiral cut extends from a peripheral edge of the stack toward the center of the each sheet. The cut forms each sheet into a generally spiral strip ending in a peninsula portion. Grasping the peninsula portion, lifting and shaking the stack causes the strips to fall and entangle with each other. The resulting structure is decorative and may be used to stuff a gift box, bag or basket.
