Compact Baking Paper Dispenser With Folded Stack And Partition Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baking paper dispensers are bulky and impair workspace usage, as larger stacks of baking paper sheets with anti-adhesion silicone coating experience high friction, causing additional sheets to be dragged when one is pulled out, leading to inefficiencies in sheet removal.
Innovation Solution
A compact baking paper dispenser with a folding box container that stores sheets at least twice folded, featuring a removal opening along the entire length with convex and concave envelope areas and limiting elements to prevent adjacent sheets from being pulled out, ensuring easy individual sheet removal and retention within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple stacks of baking paper are stored in a container, then the friction between adjacent sheets increases causing additional sheets to be pulled along, but individual sheet removal becomes difficult
Solution Approach 1:
The container is divided into multiple compartments by partition walls, with each compartment containing a separate stack of baking paper sheets. This segmentation isolates the stacks from each other, reducing the friction between adjacent sheets and enabling easy individual sheet removal from each stack without dragging additional sheets.
2Volume of moving object
If the container length corresponds to half the sheet length, then the dispenser is compact, but the container becomes bulky and impairs workspace usage
Solution Approach 1:
The baking paper sheets are folded lengthwise multiple times (at least two folds) before being placed in the container. This dimensional transformation reduces the length of the sheets that need to be accommodated in the container, allowing for a compact container design that does not impair workspace usage while still holding sufficient sheets.
3Ease of operation
If stacks are separated by dividers, then individual sheet removal is improved, but the device complexity increases
Solution Approach 1:
The partition walls separating the stacks are designed as thin, flexible cardboard dividers that extend only partially through the container height. These thin film partitions provide effective separation to prevent sheets from adjacent stacks from being pulled along, while minimizing the added structural complexity and maintaining a simple overall container design.
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 compact design allows for easy and individual removal of baking paper sheets with reduced friction, maintaining the stack's integrity and minimizing space requirements, enhancing workspace efficiency and handling convenience.
Implementation Method 1
The baking paper sheets have an anti-adhesion silicone coating, it is possible to pull individual sheets out of the container. The friction between adjacent sheets in a stack is greater with heavy stacks containing many sheets than with small stacks containing fewer sheets.
Implementation Method 2
Each baking paper sheet has flexurally elastic properties. When sections of the stack are folded over, the elastic restoring forces of the baking paper sheets cause adjacent sections of the stack to be pushed apart at the folding areas as far as the limited movement space within the container allows.
