String Cutting and Storage Assembly with Guide Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for cutting string often involve unsafe instruments like knives or scissors, and can lead to tangling and disorganization of the string, especially in applications like breakaway roping where quick and safe cutting is essential.
Innovation Solution
A string cutting and storage assembly that includes a container for holding a spool of string, a lid with a channel for guiding the string, and a blade assembly that allows for safe and convenient cutting of the string, all integrated into a single device that can fit within a typical rope can.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cutting instrument like a knife or scissors is used to cut string, then the string can be cut, but the cutting process becomes unsafe and the string can become entangled and disorganized
Solution Approach 1:
The patent combines the cutting function and storage function into a single integrated assembly. The blade assembly is mounted within the container lid, creating a unified device that performs both cutting and string storage, eliminating the need for separate cutting instruments and reducing the risk of entanglement and injury.
Solution Approach 2:
The container lid serves multiple functions: it acts as a protective cover for the string storage container and simultaneously houses the blade assembly for cutting string. This multi-functional design reduces the number of separate components needed and improves safety by integrating the cutting function into the storage system.
2Ease of operation
If string is stored on a spool without a containment structure, then the string is easily accessible, but the string becomes partially unwound leading to entanglement and disorganization
Solution Approach 1:
The spool is nested within the container, with the string passing through a guide channel in the lid. This nested arrangement allows the string to be stored compactly on the spool while maintaining organized access through the guide channel, preventing entanglement and disorganization.
Solution Approach 2:
The guide channel acts as an intermediary element that controls the path of the string from the spool to the exterior. This intermediary structure ensures the string remains organized and directed, preventing random unwinding and entanglement while maintaining easy accessibility.
3Ease of operation
If a blade assembly is integrated into the lid, then cutting becomes safe and convenient, but the device complexity increases
Solution Approach 1:
The blade assembly is merged with the lid structure, creating an integrated cutting mechanism. The blade is positioned within the lid and works in conjunction with the guide channel, combining multiple functions into a single unified component that improves cutting convenience without requiring entirely separate systems.

AI summary
A string-cutting assembly includes a container configured to hold a spool of string within an interior volume of the container. The container is substantially cylindrical. The assembly further includes a lid removably coupled to the container. At least the lid defines a first channel configured to guide a strand of the spool of string from within the interior volume to an exterior of the container. The assembly further includes a blade assembly removably coupled to the lid. The blade assembly at least partially forms a second channel configured to guide the strand to a blade of the blade assembly. The blade assembly is to retain the strand after a portion of the strand is cut.
