Modular Dual-Hook Assembly for Secure One-Handed Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooks require two-handed operation or manual intervention to secure lines or tools to objects, and tend to disengage when load forces vary, especially when attaching to objects with closed ends or by unmanned platforms.
Innovation Solution
A modular hook assembly featuring two mirror-imaged hooks with perpendicular extensions, a hinge, and a resilient member that biases the hooks to an open position, allowing one-handed operation or unmanned attachment to various objects, including those with closed ends, by maintaining a secure grip under varying loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single static hook is used, then the structure is simple, but the hook tends to slide or slip off the object requiring two hands to secure it
Solution Approach 1:
The hook is divided into two separate hook members (first hook member and second hook member) that can move independently relative to each other through a hinge connection. This segmentation allows each hook member to independently engage with the object, providing redundancy that prevents disengagement while maintaining one-handed operation capability.
Solution Approach 2:
The hook assembly transitions from a static single hook to a dynamic dual-hook system with a hinge that allows relative movement. The resilient member provides dynamic biasing force to maintain the hooks in an open position until engagement, enabling adaptive response to load variations and preventing disengagement under varying forces.
2Ease of operation
If a single hook is used, then the device complexity is low, but it requires two hands to tie the hook onto the object securely
Solution Approach 1:
The hook is divided into two separate hook members (first hook member and second hook member) that can move independently relative to each other through a hinge connection. This segmentation allows each hook member to independently engage with the object, providing redundancy that prevents disengagement while maintaining one-handed operation capability.
Solution Approach 2:
The hook assembly transitions from a static single hook to a dynamic dual-hook system with a hinge that allows relative movement. The resilient member provides dynamic biasing force to maintain the hooks in an open position until engagement, enabling adaptive response to load variations and preventing disengagement under varying forces.

If a static hook is used, then the structure is simple, but the hook cannot securely attach to objects with closed ends

The hook is divided into two separate hook members (first hook member and second hook member) that can move independently relative to each other through a hinge connection. This segmentation allows each hook member to independently engage with the object, providing redundancy that prevents disengagement while maintaining one-handed operation capability.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure one-handed or unmanned attachment and detachment of lines or tools to objects, reducing the likelihood of disengagement under changing loads, and accommodating symmetrical and non-symmetrical objects with closed ends.
Implementation Method 1
A resilient member exerts a constant force at the hinge to bias the first hook and the second hook toward an open position
Data Source
AI summary
A hook assembly includes a first hook having a first open end and a second hook having a second open end. The first hook is parallel to the second hook where the first open end is adjacent to the second open end. Extensions extend from each of the first hook and the second hook. The extensions extend perpendicular to a hook plane of the first hook and the second hook members. The first hook is a mirror image of the second hook. A hinge connects the first hook to the second hook. The hinge is located at an opposite end of the hook from where the extensions are located. A resilient member exerts a constant force at the hinge to bias the first hook and the second hook toward an open position.
