Roll-Dispensed Stock Container With Retractable Cutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current products for dispensing and cutting roll-dispensed stock materials, such as paper and foil, are large, bulky, costly, and unsafe due to exposed cutting implements, leading to issues like tearing and bunching.
Innovation Solution
A roll-dispensed stock container with a body and a cutter assembly featuring a slidable cutter and elongated track, along with fixation strips or coatings to securely hold the stock in place, allowing for clean and safe cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If current products are used to dispense and cut roll-dispensed stock, then cutting function is provided, but the products are large, bulky, and costly
Solution Approach 1:
The container is divided into functional sections: a body for holding the roll, a lid with an integrated cutter assembly, and fixation strips positioned at specific locations. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure compact and cost-effective.
Solution Approach 2:
The lid serves multiple functions: it closes the container to protect the roll, provides a mounting surface for the cutter assembly, and works with fixation strips to secure the stock during cutting. This multi-functionality reduces the need for separate components, decreasing overall product size and manufacturing cost.
2Reliability
If current cutting products are used, then cutting capability is provided, but they are unsafe due to exposed cutting implements
Solution Approach 1:
The cutting function is extracted from a separate tool and integrated into the container lid. The blade is housed within the lid structure and only exposed when needed for cutting, removing the safety hazard of permanently exposed cutting implements while maintaining cutting capability.
Solution Approach 2:
The fixation strips are positioned and the lid is closed before cutting occurs, securing the stock in place. This preliminary securing action ensures the stock is properly positioned and tensioned before the blade is engaged, making the cutting process safer and more convenient.
3Manufacturing precision
If roll-dispensed stock is cut without proper fixation, then cutting can be performed, but tearing and bunching occur
Solution Approach 1:
Fixation strips are positioned at specific local areas where the stock needs to be secured during cutting. This localized fixation provides the necessary tension and stability to prevent tearing and bunching without requiring a complex overall fixation mechanism.
Solution Approach 2:
The fixation strips act as intermediaries between the stock and the cutter assembly. They provide the necessary friction and tension to hold the stock in place during cutting, ensuring clean cuts without requiring complex clamping or securing mechanisms.
4Manufacturing precision
If tension is not maintained on roll-dispensed stock, then cutting can be attempted, but consistent cutting cannot be achieved
Solution Approach 1:
The lid is closed and fixation strips are engaged before cutting occurs, establishing tension on the stock in advance. This preliminary tensioning ensures the stock is properly positioned and under consistent tension throughout the cutting process, achieving consistent cutting results.
Solution Approach 2:
The physical state of the stock changes from loose and unpositioned to tensioned and secured when the lid is closed and fixation strips are engaged. This parameter change in tension and position ensures consistent cutting by maintaining stable conditions throughout the cutting process.
