Dispenser With Integrated Cutter And Folder Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for foil strips lack the ability to selectively apply a fold, are complex, and costly, making them inefficient for applications requiring either folded or unfolded foil strips.
Innovation Solution
A dispenser with a guide, cutter, folder, and drive mechanism that allows for customizable cutting and folding by moving the cutter and folder in opposite directions, enabling users to choose whether to fold the strip, and featuring a compact design with a rotary drive mechanism and adjustable feed rollers for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a dispenser is designed to automatically fold foil strips, then labor is saved and efficiency is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the cutter and folder into a single integrated assembly that performs both cutting and folding operations. The folder is positioned adjacent to the cutter blade, and both functions are actuated by the same drive mechanism, reducing the need for separate components and simplifying the overall device structure while maintaining automated functionality
Solution Approach 2:
The drive mechanism is designed to perform multiple functions: it drives the cutter for cutting operations and the folder for folding operations. This multi-functional approach eliminates the need for separate actuators for each function, thereby reducing device complexity while preserving productivity benefits
2Manufacturing precision
If a dispenser is designed with fixed folding capability, then folding consistency is improved, but adaptability to different user needs deteriorates
Solution Approach 1:
The patent makes the folding function dynamic and selectable rather than fixed. The controller can be programmed to optionally activate the folder based on user preferences or specific application requirements. This allows the dispenser to adapt between folded and unfolded output, providing versatility while maintaining fold consistency when the folding function is activated
3Ease of operation
If separate actuators are used for cutter and folder, then independent control is improved, but device complexity and cost increase
Solution Approach 1:
The cutter and folder are mechanically integrated into a single assembly where the folder is positioned adjacent to the cutter blade. Both components are actuated by the same drive mechanism, eliminating the need for separate actuators. The integrated design maintains functional independence through sequential or simultaneous operation controlled by a single actuation system

AI summary
A dispenser (10) for dispensing cut lengths of material strip (16) of the type capable of maintaining a crease. The dispenser 10) comprises a guide (18) for guiding a strip of material (16) through the dispenser (10); a cutter (22) for cutting a strip of material (16) to a desired length; a folder (24) for folding an end of a strip of material (16); and a link between the cutter (22) and the folder (24) for causing movement of the cutter (22) and folder (24) when one of the cutter 22 or folder (24) is moved by a predetermined amount in one of a first or second direction to actuate cutting or folding. The dispenser (10)further comprises a drive mechanism for driving movement of the cutter (22) and/or the folder (24). The drive mechanism is configured for causing movement in two directions, such that movement in one of the first or second direction actuates cutting of the strip material (16) and movement in the other of the first or second direction actuates folding.
