Wearable Electrode Harness for Simulated Gunshot Wound Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 'Officer Down' training scenarios for police and military personnel lack realism as they do not adequately simulate the pain and trauma of a gunshot wound, limiting the effectiveness of training in high-stress combat situations.
Innovation Solution
A wearable training apparatus with remotely controlled electrodes that temporarily immobilize specific muscle groups by causing muscle contractions, simulating the effects of a gunshot wound, allowing trainees to practice maintaining accuracy and focus under simulated stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Officer Down training scenarios are used, then training can be conducted with simple props and minimal equipment, but the training lacks realism and does not adequately simulate the pain and trauma of gunshot wounds
Solution Approach 1:
The patent replaces mechanical props (guns, wounds, bandages) with an electrical stimulation system. Electrodes applied to the trainee's skin deliver controlled electrical currents that cause muscle contractions, simulating gunshot wound effects without physical injury or complex mechanical props.
Solution Approach 2:
The system changes the parameter of muscle stimulation by applying variable electrical currents through controlled pulses. The intensity, duration, and pattern of electrical stimulation can be adjusted to simulate different types and severities of gunshot wounds, providing realistic training feedback.
2Ease of operation
If trainees use their off-hand to complete combat shooting courses after simulating being hit, then they can finish the training scenario, but it does not accurately model the functional impairment and pain experienced in actual gunfights
Solution Approach 1:
The electrical stimulation system is activated by the trainee themselves through a trigger mechanism, allowing them to voluntarily induce the muscle contraction that simulates the gunshot wound. This self-activation ensures proper positioning and timing of the stimulation to accurately reflect real-world trauma conditions.
Solution Approach 2:
The system provides immediate tactile feedback to the trainee through controlled muscle contractions in the targeted body part. This feedback mechanism creates realistic training scenarios where trainees experience the physical effects of being shot, improving their ability to respond appropriately in actual combat situations.
3Extent of automation
If the electrode activation system is made remotely controllable, then trainer precision and control over training scenarios is improved, but the device complexity and control system requirements increase
Solution Approach 1:
A wireless receiver assembly serves as an intermediary between the trainer and the electrode system. The receiver, worn by the trainee, receives control signals from the trainer and automatically activates the appropriate electrodes, eliminating the need for direct physical connection or complex wiring while maintaining precise control.
Solution Approach 2:
The patent replaces complex mechanical switching and wiring systems with wireless electronic communication. The trainer uses a simple remote control device that transmits signals wirelessly to the receiver, which then activates the electrodes through electrical circuits, reducing physical complexity while enhancing control precision.
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
Enhances the realism of training scenarios by inducing temporary muscle immobilization, allowing trainees to practice combat skills under more realistic and stressful conditions, improving their ability to react and respond accurately during simulated gunfights.
Implementation Method 1
The wireless receiver assembly, responsive to the activation signals, causes the battery to activate one or more of the electrodes and thereby cause contraction of at least one muscle of the trainee that is closely juxtaposed with the electrode activated by the battery

AI summary
A personal under fire trainer includes a harness holding a wireless receiver and plural electrode leads. The harness can be donned by a trainee and the leads connected to electrodes attached to the trainee's body. A trainer can operate a remote transmitter to send a signal to the receiver, activating one or more electrodes which contract the trainee's muscles, forcing the trainee to react under simulated gun fight conditions while receiving simulated gunshot wounds.
