Security Composition with Markers for Unauthorized Access Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing problem of theft and unauthorized access to restricted areas, such as street utility boxes and manholes, where protective coverings can be damaged or removed, leaving these areas vulnerable to theft and unauthorized entry.
Innovation Solution
A security product comprising a pouch containing a composition of a liquid, polymer, light-emitting material, and multiple marker materials, which forms a film upon drying and can be transferred to surfaces, clothing, or skin, facilitating identification and detection of unauthorized access and theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective coverings are used to secure restricted areas, then unauthorized access is prevented, but the coverings can be damaged or removed by weather, traffic or wear and tear
Solution Approach 1:
The patent applies marker materials to the protective coverings before they are installed or before theft occurs. This preliminary marking ensures that if the covering is removed or damaged, the marker remains on the underlying structure or stolen items, providing continuous detection capability throughout the covering's service life regardless of weather, traffic or wear conditions.
2Measurement precision
If markers are applied to detect theft, then unauthorized access can be detected, but existing markers may not persist when coverings are removed or damaged
Solution Approach 1:
The patent extracts the marker application from being solely dependent on the protective covering's integrity. By applying markers that can withstand covering removal and degradation, the detection system becomes independent of the covering's physical state, ensuring continuous detection capability even when coverings are damaged or removed by unauthorized persons.
Solution Approach 2:
The patent changes the physical or chemical parameters of the marker materials to enhance their persistence and adherence properties. This ensures the markers remain attached to surfaces or items even when protective coverings are removed or damaged, maintaining detection accuracy throughout the entire operational period.
3Measurement precision
If multiple marker materials are used to identify stolen goods, then detection accuracy is improved, but the complexity of the composition increases
Solution Approach 1:
The patent combines multiple marker materials with different detection methods (e.g., fluorescent, phosphorescent, conductive, magnetic markers) into a single integrated composition. This unified approach maintains high identification accuracy through multiple detectable properties while simplifying application and reducing the need for separate marking systems.
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
Effectively deters and detects unauthorized entry and theft by providing a persistent marker that can be used to identify individuals and tools involved in unauthorized access, thereby reducing the risk of property theft and damage.
Implementation Method 1
a composition comprising a mixture of a liquid, a polymer, a light-emitting material and a plurality of marker materials
Data Source
AI summary
A security product is disclosed herein comprising a pouch containing a composition, the composition including a mixture of a liquid, a polymer, a light-emitting material and a plurality of marker materials. The pouch may form part of a blocking device blocking an access passage that gives access to a restricted area, such as a manhole, and the composition may be transferred onto an object or individual coming into contact with the composition if an attempt is made to break through the pouch.
