Perforated Tray Facial Mask Sheet Package Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial mask sheet packaging methods require separate opening of each sheet, leading to wet hands and complex handling, with sheets often sticking together, making them difficult to remove and use efficiently.
Innovation Solution
A facial mask sheet package featuring a perforated tray with a hole at the bottom, stored in a pillow bag with a butt joint, where the tray is positioned opposite the seal, allowing easy removal and spreading of sheets without excessive wetting, using a pre-formed liquid-impermeable sheet to seal the hole and a window for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individually packaged wet sheets are packed in a single bag, then bacterial growth and contamination are prevented, but the package must be opened separately one by one to use the sheet
Solution Approach 1:
The package is segmented into multiple compartments within a single bag, with each compartment containing one wet sheet. This allows the sheets to be stored separately to prevent contamination while enabling easy access to individual sheets without opening multiple separate packages.
Solution Approach 2:
A partition structure acts as an intermediary element that divides the bag into separate compartments. This partition maintains the protective separation of each wet sheet while allowing the entire package to be opened as a single unit for convenient access.
2Ease of operation
If wet sheets are folded and stacked in a pop-up manner in a plastic container, then easy removal is achieved, but the manufacturing process becomes complex
Solution Approach 1:
Instead of folding sheets in complex pop-up manners to achieve easy removal, the invention inverts the approach by using a simple flat folding method combined with a partitioned bag structure. The ease of removal is achieved through the package design rather than complex sheet folding, simplifying the manufacturing process.
3Device complexity
If small wet sheets are stacked in a sealable container, then storage is simplified, but the sheets easily stick together making separation difficult
Solution Approach 1:
The container is divided into multiple compartments using partitions, with each compartment holding a single wet sheet. This segmentation prevents sheets from sticking together by maintaining physical separation, while the overall container structure remains simple and sealable.
Solution Approach 2:
Different regions of the container (compartments) are designed with specific local characteristics - each compartment is a separate enclosed space that prevents sticking. This local differentiation in structure solves the sticking problem while maintaining overall container simplicity.
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
Facial mask sheets can be easily removed and spread without wetting the hands, preventing sticking and simplifying handling, while maintaining airtight storage to preserve the sheets until use.
Implementation Method 1
the hole is pre-formed and sealed with a liquid-impermeable sheet so that it is opened when the liquid-impermeable sheet is removed
Implementation Method 2
the tray is stored in a pillow bag whose top side has a butt joint formed by sealing the ends of a film
