Paper Roll Dispenser Integrating Crumpling and Cutting Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crumpled paper machines are complex and inefficient, requiring additional cutting tools and often causing operational interference, making them difficult to use for both cutting and crumpling paper.
Innovation Solution
A paper roll dispenser with a press plate, guide device, and crumpled paper device that allows for adjustable paper roll direction, enabling both cutting and crumpling functions with a single device, using a funnel-shaped crumpled paper device and a cutting member to produce creases and cut paper efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional crumpled paper machine is used, then paper constriction function is achieved, but device complexity increases and cutting function is lacking
Solution Approach 1:
The patent combines the crumpling mechanism and cutting mechanism into a single integrated device. The crumpled paper machine includes both a constriction assembly for crumpling paper and a cutting assembly with a cutting blade, allowing both functions to be performed by one device rather than requiring separate tools.
Solution Approach 2:
The device is designed to perform multiple functions: it can crumple paper through the constriction assembly and cut paper through the cutting assembly. This multi-functional design eliminates the need for separate cutting tools while maintaining a relatively simple overall structure.
2Ease of operation
If paper roll, guide roller and brake arm rolling wheel are provided at same side, then device compactness is improved, but operational interference occurs
Solution Approach 1:
The patent distributes components across different spatial dimensions rather than concentrating them on one side. The paper roll is positioned at one end, the guide roller at the other end, and the brake arm rolling wheel is positioned to work with the paper feed path, creating a linear arrangement that prevents operational interference while maintaining compactness.
3Adaptability or versatility
If extra cutting tools are used for paper cutting, then cutting function is achieved, but safety hazards increase
Solution Approach 1:
The cutting blade is integrated into the crumpled paper machine structure, eliminating the need for separate cutting tools like scissors or art knives. The cutting assembly is positioned within the device framework, allowing paper to be cut as part of the normal operation without requiring users to handle external cutting instruments.

AI summary
A paper roll dispenser can be installed with a paper roll, which is parallel to a long press plate, which has an upper side connected with a hold-down strip. When the paper of the paper roll contact with the hold-down strip, the paper exceeds the paper roll can produce cutting effect. A guide roller is provided beneath the paper roll and if change the direction of the paper roll, the paper of the paper roll can be connected to a crumpled paper device by means of the guide roller, able to produce an effect of constriction of the paper, thus tallying with demand of ergonomics.
