Synthetic Marker Identification System for Crime Scene Suspect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identification systems for crimes, such as robberies and burglaries, face challenges in providing positive identification of suspects due to limited surveillance quality, lack of witnesses, and delayed police response, often resulting in suspects being released without sufficient evidence.
Innovation Solution
A non-invasive identification system that disperses a unique, synthetic marker onto suspects during crimes, allowing for positive identification using a detector, which can be activated manually, remotely, or automatically through sensors and alarm systems, ensuring legal standards of proof are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard alarm systems and surveillance cameras are used, then crime detection is enabled, but suspect identification precision deteriorates due to limited resolution and lack of unique identifiers
Solution Approach 1:
The system applies marking substance to suspects in advance of police intervention, during the commission of the crime. This preliminary marking ensures that when police arrive, the suspect already carries unique identification evidence, eliminating the information loss that occurs with delayed identification attempts.
Solution Approach 2:
The marking substance acts as an intermediary carrier of identification information. Instead of relying directly on surveillance cameras to capture and transmit suspect identifiers, the system uses the marking substance as a mediator that physically carries the crime scene location information on the suspect's body, bridging the gap between crime commission and police detection.
2Speed
If police response time is delayed, then suspects have time to flee, but identification opportunities are lost
Solution Approach 1:
The marking substance is applied to the suspect during the crime itself, before the suspect can flee. This preliminary action ensures that identification evidence is already in place on the suspect, eliminating the time loss associated with attempting to identify fleeing suspects through surveillance or witness testimony.
3Reliability
If surveillance cameras with limited resolution are used, then crime monitoring is possible, but positive suspect identification becomes difficult
Solution Approach 1:
The system applies marking substance to suspects during the crime, providing positive identification evidence that does not depend on surveillance camera resolution. This preliminary marking action ensures that when police arrive, they have reliable identification evidence regardless of the quality of video footage.
Solution Approach 2:
The marking substance serves as an intermediary identification mechanism that bypasses the limitations of surveillance cameras. Instead of relying on cameras to capture sufficient detail for identification, the system uses the marking substance as a mediator that provides clear, unique identification information directly on the suspect.
4Device complexity
If manual alarm activation is required, then system complexity is reduced, but response time increases
Solution Approach 1:
The system uses sensors to automatically detect criminal activity and trigger the marking mechanism without requiring manual activation. This self-service approach allows the system to respond immediately to crimes, eliminating the time loss associated with manual alarm activation while maintaining relatively simple system complexity through the use of standard sensor technology.

AI summary
A marking and identification system and method includes a dispersing device configured to disperse marker therefrom when in an activated mode. An activating device is configured to arm the dispersing device from an inactivated mode wherein the dispensing device does not disperse marker to the activated mode. A triggering device is configured to operate the dispersing device and disperse marker when in the activated mode. The marker can be identified at a later time to positively identify a person that triggered the marking and identification system.
