Backing paper dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baking paper dispensers often struggle with easy removal of individual baking paper sheets, as the forces applied can lead to adjacent sheets being pulled out unintentionally, making the process difficult and inefficient.
Innovation Solution
A baking paper dispenser with a donor housing made of cardboard or corrugated cardboard, featuring a withdrawal opening adjacent to the upper front edge, a first stop with a slightly tilted surface to fan out the baking paper sheets, and retention agents in the corner areas to prevent further sheets from being pulled out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-cut sheets of baking paper are stacked and stored in a dispenser housing for removal, then individual sheets can be stored and dispensed, but the friction between adjacent sheets in heavy stacks results in additional sheets being pulled along when a sheet is removed
Solution Approach 1:
The patent divides the stack of baking paper sheets into multiple sub-stacks using internal dividers. Each sub-stack contains a limited number of sheets (e.g., 5-10 sheets), reducing the friction between adjacent sheets. This segmentation allows individual sheets to be removed easily without pulling along additional sheets, directly resolving the technical contradiction between ease of operation and productivity.
2Ease of operation
If multiple stacks are arranged in the container separated by dividers, then additional sheets being pulled along is prevented, but the dispenser becomes comparatively large and bulky
Solution Approach 1:
The patent employs a nested structure where multiple sub-stacks are arranged vertically one above the other within the same horizontal footprint. Each sub-stack is positioned directly over the previous one, creating a compact tower-like configuration. This nesting approach allows multiple stacks to be accommodated in a small area, preventing additional sheets from being pulled along while minimizing the dispenser's overall size.
3Ease of manufacture
If the container is made as a folding box, then easy manufacturing and protective packaging function are achieved, but the dimensions are still large relative to the baking paper sheets
Solution Approach 1:
The patent transitions from a horizontal arrangement of stacks to a vertical arrangement, utilizing the height dimension more effectively. By stacking sub-stacks vertically within the folding box, the design accommodates multiple stacks without increasing the horizontal footprint. This dimensional change allows the dispenser to maintain a compact footprint while still providing easy sheet removal through the top opening.

AI summary
The baking paper dispenser comprises a dispenser housing (1) with a dispensing opening and a stack (3) of baking paper sheets stored on a dispensing base (19) within the dispenser housing (1). Adjacent to the dispensing opening (17), the dispenser housing (1) includes a stop surface (5) for the leading edges of the baking paper sheets. This stop surface (5) is inclined at an angle (a) relative to the dispensing base (19) to fan out the baking paper sheets so that they can be easily removed from the dispenser housing (1) through the dispensing opening (17).
