Assisted Opening Mechanism for Wearable Self-Defense Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-defense devices, such as finger rings and automatic knives, often lack cosmetic appeal, are bulky, and are inconvenient to access quickly, making them unsuitable for emergency use.
Innovation Solution
A wearable ring assembly with an assisted opening and closing mechanism, utilizing a combination of a cylindrical shaft, elastic device, and switch mechanism, allows for quick and secure deployment of a moveable shaft, enhancing both functionality and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed pin mechanism is used to pivot the blade, then the blade can be opened and closed, but the ring becomes bulky and cosmetic appeal is limited
Solution Approach 1:
The patent employs a spring-loaded shaft that can dynamically extend and retract. The shaft transitions from a retracted position (maintaining cosmetic appeal) to an extended position (providing defensive functionality) through spring tension, allowing the ring to adapt its shape based on operational needs rather than being fixed in a bulky configuration.
Solution Approach 2:
The shaft is nested within the ring body when retracted, with only a portion visible. The spring mechanism allows the shaft to be contained within the ring's structure, creating a compact nested arrangement that maintains aesthetic appearance while enabling blade deployment when needed.
2Stability of the object's composition
If stabilizing wings are made fixed, then the blade can be stabilized, but the ring becomes bulky and may accidentally catch on items
Solution Approach 1:
The stabilizing wings are designed to be movable rather than fixed. They can extend outward to provide stability during blade deployment and retract when not needed, preventing accidental catching on items while maintaining blade stability during use. This dynamic configuration eliminates the need for permanently extended stabilizing structures.
3Reliability
If an automatic knife is kept in pocket, then it is accessible for self defence, but it is inconvenient and may be difficult to access quickly
Solution Approach 1:
The ring device is worn on the finger, placing it in immediate contact with the user and eliminating the need to reach into pockets or bags. The spring-loaded mechanism provides automatic shaft deployment when activated, reducing the time required to access the defensive function compared to retrieving a pocket knife.
4Ease of operation
If a wearable ring with self defence components is made, then it is convenient for self defence, but it looks bulky and cosmetically unappealing
Solution Approach 1:
The shaft transitions from a retracted position (maintaining cosmetic appeal) to an extended position (providing defensive functionality) through spring tension, allowing the ring to adapt its shape based on operational needs rather than being fixed in a bulky configuration.
Solution Approach 2:
Only a portion of the shaft is visible when extended, and the shaft can be oriented to minimize its visual impact. The design allows the defensive component to be localized and concealed when not in use, maintaining overall cosmetic appeal while providing self-defense 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
The solution provides a compact, cosmetically appealing, and easily accessible self-defense device that can be quickly deployed, addressing the limitations of existing designs by offering a convenient and efficient mechanism for opening and closing the shaft.
Implementation Method 1
An elastic device, and a switch mechanism. The substantially cylindrical shaft further comprises a bore; and a piston component inside the bore of the shaft
