Netting Restraint Frame for Suspect Escape Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Criminals often escape from public places by using common entrances and exits without consequences, despite immediate law enforcement contact, as existing security measures are inadequate to prevent their escape.
Innovation Solution
A security system comprising a frame with a trolley system and heavy-duty netting that can be activated to drop and lock into position over a suspect, using locks and a triggering device to immobilize the suspect until law enforcement arrives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If law enforcement is contacted immediately, then response time is reduced, but criminals still have time to flee or hide before law enforcement arrives
Solution Approach 1:
The security system performs preliminary action by automatically deploying the netting barrier immediately upon detecting a suspect, before law enforcement arrives. The triggering device activates the trolley system to drop the netting across the exit path, pre-preventing escape while waiting for police response.
Solution Approach 2:
The netting system serves as an intermediary between the crime scene and law enforcement arrival. It physically blocks the suspect's escape path during the response time gap, acting as a temporary containment barrier that bridges the time gap until police can secure the suspect.
2Ease of operation
If common egress and ingress points are used, then criminal escape is enabled, but no consequences are imposed on the criminal
Solution Approach 1:
The system applies preliminary anti-action by pre-positioning the netting above the exit path and automatically deploying it when a suspect is detected. This counteracts the criminal's intended escape action before they can successfully flee, imposing immediate physical constraint as a consequence of the crime.
Solution Approach 2:
The system converts the harm of criminal escape attempts into benefit by using the same exit path the criminal intends to use as the deployment path for the netting. The exit becomes the trap mechanism, turning the criminal's advantage into their disadvantage.
3Reliability
If a netting system is deployed to block escape, then suspect immobilization is achieved, but the system complexity increases
Solution Approach 1:
The system is segmented into independent functional modules: a frame structure, a trolley system with wheels and locks, heavy-duty netting, and a triggering device. Each component is simple in itself but combines to create an effective immobilization system, reducing overall complexity through modular design.
Solution Approach 2:
The trolley system uses gravity and its own weight to automatically travel down the rail and deploy the netting when triggered. The lock mechanism automatically engages at the bottom of the rail to hold the netting in place, requiring minimal complex control systems while achieving reliable deployment.

AI summary
A security system may use a netting to apprehend suspects of crime and prevent them from leaving the scene of the crime. The security system can include a netting, trolley system, frame, and triggering device. The netting can be connected to the trolley system. The trolley system can be supported by the frame, which can cover points of egress and ingress of buildings. When the triggering system is activated, netting can travel down the trolley system to apprehend the suspect until law enforcement has a chance to arrive on the scene.
