Self-Defense Key Holder with Pivot Deployment and Finger Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-defense key holders can be difficult to use in emergency situations, as they may require assembly and can pose a risk of injury to the user when attempting to defend oneself with a key.
Innovation Solution
A self-defense key holder apparatus that rapidly converts a standard key into a fighting weapon, featuring a key mount, user grip, and pivot couple, allowing for secure attachment and ergonomic handling, with a design that transitions between stowed and deployed states to minimize risk of injury and facilitate effective use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key is held between fingers as a makeshift self-defense aid, then self-defense capability is provided, but the user is at risk of cutting their own hand
Solution Approach 1:
A finger guard component is introduced as an intermediary between the user's finger and the key. The finger guard includes a finger slot that receives the key while providing protective surfaces that prevent the key from cutting the user's finger during self-defense maneuvers.
Solution Approach 2:
The finger guard is positioned in advance to cushion and protect the user's finger from potential injury. The protective surface of the finger guard is designed to absorb and distribute the force before it can reach the user's finger, preventing hand injury before it occurs.
2Reliability
If a self-defense key holder requires assembly, then secure attachment is achieved, but it becomes difficult to use in emergency situations
Solution Approach 1:
The key is pre-loaded into the finger guard component during normal conditions. This preliminary action ensures that when an emergency occurs, the user simply needs to deploy the pre-assembled unit by pressing against the pivot couple, eliminating the need for assembly during the critical moment.
Solution Approach 2:
The pivot couple enables dynamic transition between stowed and deployed states. The mechanism allows the finger guard to rotate from a compact stowed position to an operational deployed position through simple finger pressure, providing both secure attachment and rapid deployment.
3Reliability
If the key mount is designed to withstand thrusts, then self-defense effectiveness is improved, but the structure becomes more complex
Solution Approach 1:
The finger guard and key mount functions are merged into a single integrated component. The finger guard itself serves as the mounting structure that secures the key, while also providing protection for the user's finger. This combination eliminates the need for separate complex mounting mechanisms.
Solution Approach 2:
The finger guard component performs multiple functions: it protects the user's finger from injury, secures the key in place through the finger slot, and provides a structural element for deployment. This multi-functionality reduces overall device complexity while maintaining self-defense effectiveness.

AI summary
Aspects of the present disclosure generally pertain to an apparatus and method for holding a key for self-defense. Aspects of the present disclosure more specifically are directed toward a self-defense key holder or an apparatus that rapidly converts a key (e.g., house key) into a fighting weapon, for example, for self-defense. The defense key holder may utilize an existing key (e.g., home/office/auto) to replace bulky and often prohibited self-defense aids. This disclosure may be useful for giving a user additional control and force in a variety of motions with a key or other object.
