Compact Paper Crumpler Mechanism for Small-Scale Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispensing crumpled paper are often large, expensive, and unsuitable for small-scale users, such as home-based operations, as they require significant space and are not designed for efficient crumpling and dispensing of paper for cushioning items during shipment.
Innovation Solution
A compact paper dispenser system that uses a paper roll with an airshaft core, where the paper is crumpled as it is dispensed through a crumpler mechanism within a box, allowing for easy handling and transportation of crumpled paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If industrial-scale crumpled paper dispensing systems are used, then large volumes of crumpled paper can be produced, but the systems become large, expensive, and immovable
Solution Approach 1:
The patent divides the paper dispensing system into separate functional components: a paper roll holder, a crumpling mechanism with protrusions, and a dispensing opening. This segmentation allows each component to be simple and compact while collectively providing crumpled paper dispensing capability, resolving the contradiction between quantity production and system complexity.
Solution Approach 2:
The crumpling mechanism uses the user's own pulling action on the paper to drive the crumpling process. As the user pulls paper from the dispensing opening, the paper is automatically fed through the crumpling protrusions which create crumpled sections. This self-service approach eliminates the need for complex motors, sensors, and control systems while still providing continuous crumpled paper output.
2Productivity
If sophisticated machinery with many moving parts is used, then crumpled paper can be produced efficiently, but the system becomes expensive and difficult to operate
Solution Approach 1:
The system uses the user's natural paper retrieval action to drive the entire crumpling process. The paper is pulled through the crumpling protrusions by the user's own force, eliminating the need for separate feeding mechanisms, motors, and controls. This maintains productivity while maximizing ease of operation.
Solution Approach 2:
The patent extracts only the essential crumpling function from complex industrial systems, using simple protrusions that create crumpled sections as paper is pulled through. This extraction of the core function eliminates unnecessary moving parts while maintaining the ability to produce crumpled paper efficiently.
3Ease of operation
If decorative paper dispensation systems are used, then paper can be dispensed, but they fail to meet the needs of users who require cushioning material for shipment protection
Solution Approach 1:
The crumpling protrusions are strategically positioned and shaped to create localized crumpled sections with specific cushioning properties. The protrusions generate irregular crumpled patterns that provide effective shock absorption for shipment protection, while the overall system remains simple to operate like decorative dispensers.

AI summary
A paper crumpler has a dispenser with a bottom, a top, a side wall between the bottom and the top, and a cavity defined by the bottom, the top, and the side wall. A hole is formed in the top of the dispenser. A shelf is positioned within the cavity below the top of the dispenser. Uncrumpled paper is stored in the cavity beneath the shelf. An orifice is formed in the shelf. The orifice has protrusions that extend radially inward toward one another and that are configured to contact the uncrumpled paper when the uncrumpled paper is passed through the orifice from the cavity to thereby form crumpled paper above the shelf. The crumpled paper can be dispensed from the dispenser through the hole.
