Coreless-Wound Rope Cartridge for Tangle-Free Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rope products are cumbersome to store and use due to tangling, knotting, and unraveling, and lack a convenient method for cutting to desired lengths.
Innovation Solution
A rope dispensing system featuring a removable, replaceable rope cartridge with a canister and a cutting mechanism that allows for easy dispensing and cutting of rope to desired lengths, using precision coreless winding to prevent tangling and unraveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rope products are used, then rope can be stored and used, but the rope becomes tangled, knotted, and unraveled during storage and handling
Solution Approach 1:
The rope is segmented into a discrete cartridge unit with defined ends, contained within a canister. This segmentation prevents the rope from interacting with itself in a way that causes tangling or unraveling, as each rope is independently enclosed and dispensed through a controlled opening with a grommet.
Solution Approach 2:
The rope is pre-loaded into the cartridge in a controlled manufacturing process where it is wound and secured before use. The cartridge is pre-prepared with the rope ends secured and the rope fed through the grommet, eliminating the need for users to perform preliminary preparation that could cause tangling.
2Ease of operation
If rope is stored in conventional forms (hand coiled, spooled, or bundled), then rope can be stored, but access to the rope and cutting to desired lengths is complicated
Solution Approach 1:
The cutting mechanism is merged with the canister structure, positioning the cutting blade at the opening where the rope is dispensed. This integration allows users to cut the rope at the exact point of access without needing separate cutting tools or procedures, combining storage and cutting functions in one unit.
Solution Approach 2:
The system enables self-service cutting where the user can directly cut the rope at the desired length using the integrated cutting mechanism. The rope is accessible through the grommet and can be cut immediately at the point of dispensing, allowing users to obtain exactly the length they need without additional steps.
3Reliability
If rope is dispensed from a cartridge, then tangling is prevented, but the cutting mechanism must be integrated into the canister
Solution Approach 1:
The canister is designed with multi-functionality, serving both as a storage container for the rope cartridge and as a housing for the cutting mechanism. This universal design consolidates multiple functions into a single structure, reducing the need for separate components and minimizing overall system complexity despite the added functionality.

AI summary
A rope dispensing apparatus for rapidly dispensing a continuous rope from a compressed rope cartridge. The apparatus includes a canister for storage of the rope cartridge, a resealable lid with an opening for passing the rope from the cartridge out of the canister through the lid, and a replaceable cutting mechanism for cutting the rope when a desired length has been dispensed. Preferably, the rope cartridge is shrink-wrapped to fit within the canister and keep the rope from unraveling while therein.
