Rotary Clip-Hook Joint for Secure Bag Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for suspending purses and bags lack versatility, durability, and convenience, often resulting in soiling or intrusiveness when placed on surfaces, and fail to provide a secure and aesthetically pleasing mechanism for varying orientations and uses.
Innovation Solution
A combination clip and hook structure with a rotatable joint that transitions between a closed shape for securing straps and an open S-shaped hook for suspension, featuring a spring-loaded pivot assembly with indexing positions, allowing for secure attachment to various surfaces and enabling multiple uses such as jewelry or accessory integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a purse or bag is placed on a table or countertop for easy access, then it is within reach and visible, but it becomes intrusive and may be subject to soiling from spilled liquid and food
Solution Approach 1:
The patent introduces a hook as an intermediary device between the purse and the supporting surface. The hook allows the purse to be suspended in mid-air rather than placed directly on the table, eliminating contact with potentially soiling surfaces while maintaining easy accessibility within reach
2Reliability
If a purse or bag is placed beneath the owner's legs for close proximity, then it is secure and close to the person, but it is subject to soiling and spilled liquid
Solution Approach 1:
The hook serves as an intermediary that allows the purse to be suspended close to the owner's seating position without actual contact with the legs or floor. The purse hangs in a protected position that maintains proximity for security while avoiding contamination zones
3Adaptability or versatility
If a delicate hinge and clasp mechanism is used for jewelry closure, then it allows for opened and closed orientations, but it is prone to breakage and difficult to manipulate
Solution Approach 1:
The patent replaces static, delicate hinge mechanisms with a dynamic spring-loaded rotary joint. This joint uses elastic deformation of spring elements to provide the closing force, allowing the structure to flex and return to its closed position without permanent deformation or breakage, while maintaining the ability to open and close repeatedly
Solution Approach 2:
The spring-loaded mechanism is self-actuating - when the rotary joint is released, the spring automatically returns the structure to its closed position without requiring manual manipulation of delicate components. The system serves itself by using stored elastic energy to perform the closure function
4Adaptability or versatility
If a rotatable joint mechanism is added to allow orientation changes, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent merges the closure mechanism and the rotatable joint into a single integrated assembly. The rotary joint serves dual purposes: it provides the closure function by bringing the ends together and simultaneously enables rotation to different orientations. This combination eliminates the need for separate hinge and rotation mechanisms, reducing overall complexity
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
The solution provides a sturdy, versatile, and aesthetically pleasing mechanism for suspending bags and accessories, maintaining cleanliness and proximity while allowing for secure attachment to various surfaces, with the ability to transition between closed and open orientations for different functions.
Implementation Method 1
The joint between the two portions can define a spring-loaded rotating pivot assembly with at least two indexing positions

AI summary
A combination clip and hook (clip) for use generally in suspending articles, which is rotatably movable about a rotary joint between a first position in which two opposing, rotatably joined portions of the overall clip structure are oriented together to form a continuous, enclosed shape that can be secured around another, and a second position in which the two portions of the structure are rotated out of the enclosed shape, and into, for example, a S shaped hook where one portion of the structure supports the item and the other portion can be applied to another supporting member. The joint between the two portions can define a spring-loaded rotating pivot assembly with at least two indexing positions opposed by 180 degrees. The rotary joint can be constructed with a pair of confronting male and female wedge and detent inserts that are biased toward each other by an embedded spring assembly.
