Extendable Strap Restraint With Biasing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Police officers face challenges in restraining uncooperative individuals without using injurious amounts of physical force during aggressive confrontations, as existing non-lethal options often require substantial physical effort that can be harmful.
Innovation Solution
A non-lethal restraining device featuring an extendable strap retained within a body that can be deployed and tightened around a person's body, utilizing a biasing element to restrict movement without causing injury, with control points for safe manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If substantial physical force is applied to restrain a person, then the person can be placed in a position to be handcuffed or rendered harmless, but the force may be physically injurious to the person
Solution Approach 1:
The patent introduces a restraining device as an intermediary tool between the officer and the subject. The device includes a strap with a first end attached to a device body and a second end that can be positioned around the subject's body, allowing restraint without direct substantial physical force application by the officer
Solution Approach 2:
The restraining device is designed to be deployed and secured with minimal physical effort from the officer. The device body facilitates automatic or semi-automatic restraint application, reducing the need for injurious manual force while maintaining restraint effectiveness
2Object-affected harmful factors
If non-lethal options are used for restraint, then injury risk is reduced, but substantial physical effort is still required which can be harmful
Solution Approach 1:
The device acts as a mechanical intermediary that converts minimal officer effort into effective restraint. The device body and strap mechanism provide mechanical advantage, allowing the officer to secure the subject without expending substantial physical effort
Solution Approach 2:
The patent replaces the mechanical system of direct human physical force with a device-based mechanical system. The device body, strap, and fastening mechanisms provide the necessary mechanical advantage to restrain a subject without requiring the officer to apply substantial physical effort
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 restrains individuals without causing physical harm, allowing for safe control and immobilization with minimal physical force, enhancing safety for both the officer and the restrained person.
Implementation Method 1
The device includes a biasing element that allows the extendable restraining strap to be tightened once it has been fully deployed

AI summary
A non-lethal restraining device includes an extendable restraining strap retained within a device body until deployed, when the extendable restraining strap is then looped over a person. A biasing element allows the extendable restraining strap to be tightened once it has been fully deployed and looped around a person's body to restrict the person's movement. When the extendable strap is tightened around the person's body, the device provides control points to direct and manipulate the person safely.
