Solution Overview

Problem

Conventional winches with metal components are prone to damage and safety hazards due to unexpected line release when not fully secured, posing risks of injury and rendering the winch unusable.

Innovation Solution

A hookless winch rope system comprising two ropes with an enlarged knot and interwoven portions, forming loops and retaining notches for secure engagement without metal hooks, utilizing high-strength materials like HMPE, polypropylene, or polyester for enhanced strength and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If metal hooks or shackles are used to secure the line, then the winch can effectively pull vehicles or objects, but the metal components may become damaged or unexpectedly released, causing safety hazards and rendering the winch unusable

Engineering Contradiction:

Improvesecure engagementVSAvoiddamage to winch and injury risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes metal hooks and shackles from the winch line system entirely, extracting the harmful metal components that cause damage and safety hazards. The line is redesigned to be self-securing through its own structure (enlarged knot forming a retaining notch) without requiring separate metal fastening components.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the physical parameters of the line by incorporating an enlarged knot with a retaining notch that mechanically locks onto a corresponding feature on the winch drum. This structural parameter change eliminates the need for metal hooks while providing secure engagement through geometric interlocking.

Inventive Principle:

Principle #35Parameter changes

2Strength

If conventional metal cables are used, then the line has high strength, but the metal components pose safety risks when not fully secured

Engineering Contradiction:

Improveline strengthVSAvoidsafety security

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent replaces expensive, dangerous metal cable components with a disposable-style synthetic rope system where the line itself incorporates the securing mechanism. The synthetic rope with integrated enlarged knot is designed to be replaced if damaged, eliminating the need for separate reusable metal hooks and shackles that pose safety risks.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If hooks and shackles are attached to the line, then the winching operation can be performed, but the components may become loose and unexpectedly released

Engineering Contradiction:

Improvewinching capabilityVSAvoidcomponent security

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent merges the function of the line with the function of the securing mechanism by integrating the enlarged knot with retaining notch directly into the rope structure. This eliminates separate hooks and shackles, combining the tension-bearing line and the locking function into a single integrated component system.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A hookless winch rope for securing to an object includes a first rope having a first end and a second end. The first end has a first loop and comprising a choke. A second rope is separate from the first rope. The second rope includes a third end and a fourth end. The third end includes an enlarged knot forming an engagement notch receiving the first loop. The first rope and the second rope are joined by a first interwoven portion.
