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

VSEngineering 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

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvesmooth operationVSAvoiddevice footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If extra cutting tools are used for paper cutting, then cutting function is achieved, but safety hazards increase

Engineering Contradiction:
Improvecutting capabilityVSAvoidsafety risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #5Merging (Combining)

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.
