Constraining Bar Trigger Mechanism for Non-Lethal Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for restraining individuals in lawless situations, such as riots or civil disturbances, often fail to effectively and safely constrain moving targets without causing excessive injury, as they can be difficult to apply, excessively forceful, or risk severe injury.
Innovation Solution
A constraining device with a housing forming a receiving chamber, rotating paddles, and a constraining bar that can be moved linearly by a trigger mechanism, allowing for secure trapping of the target between the paddles, housing, and constraining bar, enabling efficient and non-lethal restraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional restraining devices (handcuffs, tear gas, rubber bullets, electric tasers) are used on fast-moving targets, then the restraining function can be achieved, but the device becomes difficult to apply, excessively forceful, or risks inflicting severe injury
Solution Approach 1:
The constraining bar is pre-loaded into a tensioned state before activation, with elastic members already stretched and energy stored. When triggered, the bar rapidly moves to constrain the target without requiring aim adjustment or manual manipulation during the critical moment of application, solving the difficulty of applying restraining devices to fast-moving targets
2Productivity
If conventional restraining devices are applied to fast-moving targets, then restraining capability is maintained, but the device becomes difficult to apply accurately and quickly
Solution Approach 1:
The device is designed to be propelled and positioned by the user's throwing or swinging motion rather than requiring manual manipulation of complex mechanisms. The internal elastic members automatically tension and lock the constraining bar in place upon activation, eliminating the need for precise aiming or coordinated manual operation during the restraint process
Solution Approach 2:
The constraining bar transitions from a static loaded position to a dynamic restrained position through rapid movement activated by the trigger mechanism. The elastic members provide automatic tensioning and locking, allowing the device to adapt to the motion of fast-moving targets while maintaining restraining effectiveness
3Object-affected harmful factors
If conventional restraining devices are used, then restraining function is achieved, but the force applied is excessively severe or unnecessary
Solution Approach 1:
The constraining force is concentrated locally at the receiving chamber where the target is trapped between the constraining bar and housing, rather than applying diffuse force throughout the body. The elastic members provide controlled tension only at the point of contact, achieving reliable restraint with minimal necessary force and reducing the risk of severe injury to non-target areas
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 allows for quick and secure constrainment of targets, preventing escape while minimizing the risk of injury, making it suitable for law enforcement and other scenarios where non-lethal restraint is necessary.
Implementation Method 1
a first elastic member connected at a first end thereof to the base portion and at a second end thereof to the holding device, the first elastic member configured to transition between a resting state when the holding device is in the retracted position and a tensioned state when the holding device is in the holding state, causing extension of the first elastic member

AI summary
An apparatus can include: a housing configured to form a receiving chamber that is operable to receive an object; first and second paddles disposed at a distal end of the receiving chamber; a constraining bar movably disposed within the housing and configured to translate linearly along a length of the receiving chamber; and a trigger mechanism configured to releasably couple the constraining bar to the housing. When the constraining bar is in a loaded position, the trigger mechanism can be configured to release the constraining bar in response to a proximally-directed force exerted on the constraining bar, causing the constraining bar to translate distally along the length of the receiving chamber.
