UV Powder Spray System for Bank Robbery Deterrence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bank robbery deterrents like dye packs are costly, prone to accidental detonation, and have become ineffective due to widespread knowledge among robbers, posing challenges for banks to comply with law enforcement identification requirements.
Innovation Solution
A system and method using a spray delivery device that releases an ultraviolet light powder (UV powder) as an identifying substance, which is undetectable to the naked eye but visible under UV light, to mark intruders, allowing for easy identification by police, activated via an alarm system or manual trigger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dye packs are used as robbery deterrents, then identification capability is improved, but safety and cost-effectiveness deteriorate due to accidental detonation risk and high maintenance costs
Solution Approach 1:
The patent replaces the mechanical explosive system of dye packs with a non-explosive spray mechanism. Instead of using detonation to disperse dye, the system uses a controlled spray device that releases identifying substance without explosive force, eliminating the safety hazards associated with accidental detonation while maintaining the identification function.
Solution Approach 2:
The patent changes the physical state and delivery method of the identifying substance. Rather than using explosive dispersion, the system employs a pressurized spray mechanism that delivers the identifying substance in a controlled liquid or aerosol form, fundamentally changing how the substance is released and applied to suspects.
2Measurement precision
If dye packs are deployed, then identification capability is improved, but cost and complexity increase due to installation and maintenance expenses
Solution Approach 1:
The patent employs disposable or easily replaceable spray canisters that can be quickly swapped without complex installation procedures. This eliminates the need for expensive permanent installations and reduces maintenance costs, as the spray mechanisms are designed to be simple, modular units that can be replaced rather than repaired.
3Measurement precision
If identifying substances are applied, then identification capability is improved, but detectability worsens if the substance is visible to the naked eye
Solution Approach 1:
The patent uses identifying substances that change their optical properties based on the detection method. The substance appears invisible or nearly invisible under normal lighting conditions but fluoresces or changes color when exposed to ultraviolet light, allowing police to detect and identify suspects without the substance being visible to robbers during the commission of the crime.
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
Provides a safe, cost-effective alternative to dye packs, ensuring accurate identification of suspects even if they change clothing, reducing the risk of accidental detonation and enhancing deterrence without negatively impacting customer experience.
Implementation Method 1
The pressurized substance may be a spray, such as an ultraviolet light powder (UV powder), that leaves an invisible film
Data Source
AI summary
The present application discloses systems and methods for marking an individual with an identifying substance. The system includes a spray delivery device configured to release a pressurized substance in response to an activation signal, an activation device configured to transmit an activation signal to the spray delivery device, and a power supply, configured to provide power to at least one of the activation devices and the spray delivery devices. The method includes storing a pressurized substance, receiving an activation signal at a spray delivery device, and releasing the pressurized substance in response to the received activation signal.
