Flashlight Stun Gun with Circular Electrode Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior stun guns are cumbersome due to being single-purpose devices, requiring separate carrying of a flashlight and stun gun, and insufficient in deterring or immobilizing assailants due to electrode placement and orientation.
Innovation Solution
A flashlight stun gun device with a cylindrical housing, embedded electrodes on a collar around a light emitting source, and discharge circuitry that allows for simultaneous electric arcs across multiple gaps, providing a regular-sized flashlight appearance with sufficient power to deter or immobilize assailants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the light is placed in the middle of the stun gun with electrodes on either side, then the device can be compact, but the gap between electrodes becomes too small to effectively deter assailants and the orientation is insufficient
Solution Approach 1:
The electrodes are arranged in a circular pattern around the light source rather than linearly on opposite sides, transitioning from a one-dimensional linear arrangement to a two-dimensional circular arrangement. This allows the electrodes to be spaced farther apart while maintaining a compact device form factor, and the circular orientation presents multiple electrode surfaces to potential assailants, enhancing the deterrent effect.
2Reliability
If a flashlight and stun gun are carried separately, then each device can be optimized for its specific function, but it becomes cumbersome to operate both devices
Solution Approach 1:
The patent combines the flashlight and stun gun into a single integrated device. The flashlight bulb is positioned at the center, with stun gun electrodes arranged around it in a circular pattern. Both functions share the same power source and housing, allowing the user to carry and operate one device that provides both illumination and self-defense capabilities.
Solution Approach 2:
The device is designed to perform multiple functions: it can be used as a flashlight for illumination and as a stun gun for self-defense. The circular arrangement of electrodes around the light source allows both functions to coexist in the same device, with the trigger mechanism controlling the stun gun function while the light can be activated independently or simultaneously.
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 device effectively combines the functions of a flashlight and stun gun, providing a regular-sized appearance with sufficient power to deter or immobilize assailants through simultaneous electric arcs across multiple gaps, enhancing personal defense capabilities.
Implementation Method 1
A light emitting source is secured to the top end of the cylindrical housing and is coupled to the power source
Implementation Method 2
First and second electrodes are embedded in a first portion of the top edge of the collar and have a first gap therebetween to generate an electric arc across
Implementation Method 3
The electrical discharge causes the assailant's muscles to uncontrollably spasm so that the assailant is temporarily paralyzed
Data Source
AI summary
A flashlight stun gun device includes a cylindrical housing having a power source coupled to discharge circuitry, where the discharge circuitry has a first lead and a second lead. In addition, a light emitting source is secured to a top end of the cylindrical housing and is coupled to the power source. A collar is secured to the top end of the housing and around the light emitting source. First and second electrodes are embedded in a first portion of a top edge of the collar and have a first gap therebetween to generate an electric arc across. Third and fourth electrodes are embedded in a second portion of the top edge of the collar opposing the first pair of electrodes and have a second gap therebetween to generate an electric arc across. The electrodes are electrically coupled together in series when the discharge circuitry is activated.
