Die-cut Paper Cushion Pad for Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cushion pads for packaging are bulky due to their thickness, leading to increased transportation costs, and existing die-cutting paper solutions require manual stretching, which can result in uneven force application and damage, while also being environmentally unfriendly.
Innovation Solution
A cushion pad made of paper material with die-cutting regions that can be unfolded to form a three-dimensional network structure, reducing thickness and transportation costs, and a packaging bag design that unfolds to provide a buffering effect when needed, using a paper material that can be recycled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional inflatable bubble structure or plastic foam is used to provide cushioning, then the cushioning function is improved, but the thickness increases leading to higher transportation costs
Solution Approach 1:
The cushion pad is divided into multiple layers with die-cutting regions creating segmented cushioning units. Each layer contains cutting slits that form individual cushioning cells, allowing the structure to provide effective cushioning with reduced overall thickness compared to conventional solid foam or bubble structures.
Solution Approach 2:
The invention transitions from a three-dimensional bulky cushioning structure to a two-dimensional flat configuration during transportation. The die-cutting regions are cut in a flat state and only form their three-dimensional cushioning shape when expanded during use, dramatically reducing transportation volume while maintaining cushioning performance.
2Reliability
If die-cutting paper is manually stretched to form a three-dimensional network structure, then the cushioning effect is improved, but the manual stretching process causes uneven force application and potential damage
Solution Approach 1:
The die-cutting regions are pre-cut with cutting slits in specific patterns during manufacturing, but the actual three-dimensional expansion is postponed until usage. This preliminary preparation allows the structure to be easily expanded later without requiring complex manual stretching operations, eliminating the risk of uneven force application and damage.
Solution Approach 2:
The cushion pad structure is designed to automatically expand and form its three-dimensional network configuration through its own structural properties when activated, without requiring external manual stretching. The die-cutting regions naturally form the cushioning cells when the flat structure is expanded, making the process self-service and eliminating manual intervention.
3Reliability
If die-cutting paper is stretched and fixed onto inner walls of an outer bag body, then the cushioning function is ensured, but the production process becomes complex
Solution Approach 1:
The invention combines the cushioning structure and the packaging bag into a single integrated unit. The die-cutting paper structure serves both as the cushioning element and as part of the bag body, eliminating the need for separate assembly steps where cushioning material would be fixed onto bag walls. This merging simplifies the production process while ensuring reliable cushioning function.
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 reduces transportation costs by maintaining a flat shape during transport and unfolding to provide a buffering effect when used, while being environmentally friendly and simplifying the manufacturing process.
Implementation Method 1
a cushion pad made of a paper material includes at least one cushion unit, each of the at least one cushion unit including at least one layer of third surface, each of the at least one layer of third surface including a die-cutting region, and a transferring region arranged at a center of the third surface
Data Source
AI summary
The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.
