Tissue Roll Pack Reinforcement for Single-Parcel Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional packs of tissue paper rolls are not suitable for single shipping due to ease of damage, which poses a challenge for e-commerce distribution.
Innovation Solution
A pack design featuring a set of rolls with a wrapping sheet and a stiffer panel surrounding the side surfaces, such as a cardboard strip, to protect the rolls from impacts and external pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packs of tissue paper rolls are used without additional protective panels, then the packaging structure remains simple and cost-effective, but the rolls are easily damaged during transport making them unsuitable for single shipping
Solution Approach 1:
The protective panel is placed inside the wrapping sheet, creating a nested structure where the rigid panel is enclosed within the flexible wrapping material. This nested arrangement provides enhanced protection to the rolls while maintaining a compact and simple external packaging appearance, resolving the contradiction between damage resistance and structural complexity.
Solution Approach 2:
The packaging combines two different materials with complementary properties: a rigid panel (cardboard or similar stiff material) for structural protection against impacts and pressure, and a flexible wrapping sheet for envelopment and cushioning. This composite structure achieves superior damage resistance while keeping the overall packaging design relatively simple.
2Strength
If a protective panel is added inside the wrapping sheet, then the rolls are protected from impacts and external pressure, but the packaging structure becomes more complex
Solution Approach 1:
The protective panel is nested within the wrapping sheet, allowing the stiff panel to provide impact and pressure protection while the flexible wrapping sheet maintains the external form. This nested configuration delivers enhanced strength without proportionally increasing structural complexity, as the panel integrates within the existing wrapping architecture.
Solution Approach 2:
The protective panel is strategically positioned to provide localized reinforcement at critical areas where rolls are most vulnerable to damage. Rather than uniformly strengthening the entire packaging, the panel applies protection precisely where needed, achieving high strength with minimal additional structural complexity.
3Adaptability or versatility
If rolls are packaged in heat-shrinkable polymer film with external bands, then multiple packs can be bound together, but individual packs remain vulnerable to damage during single shipping
Solution Approach 1:
The packaging solution segments the protection function into two levels: individual roll protection through the internal panel within each pack, and multi-pack binding through external bands. This segmentation allows each pack to be independently protected for single shipping while still enabling versatile multi-pack configurations when needed.
Solution Approach 2:
The protective panel is installed beforehand within the wrapping sheet, providing pre-cushioning and structural reinforcement to individual rolls before they are subjected to shipping conditions. This prior protection ensures that even when shipped individually, each pack maintains high reliability against damage, while the external banding system remains available for multi-pack configurations.

AI summary
The pack of tissue paper rolls comprises a set of rolls having at least one layer of rolls and having a first base, a second base and a side surface extending from the first base to the second base of the set of rolls. A wrapping sheet completely envelops the set of rolls and a panel, with greater stiffness than the wrapping sheet, surrounds the side surface of the set of rolls and is arranged inside the wrapping sheet, between it and the rolls.
