Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a perimeter security system uses traditional alarm components separately, then each component can perform its specific function, but the overall system becomes complex and requires multiple devices
Solution Approach 1:
The patent combines multiple security functions (audible alarm, visual strobe light, infrared illumination, and flashlight) into a single integrated alarm unit. This merging of previously separate components into one device directly resolves the technical contradiction by achieving multifunctionality while reducing system complexity.
Solution Approach 2:
The alarm unit is designed to perform multiple functions simultaneously: it serves as an audible alarm, visual strobe, infrared light source, and flashlight. This universal design allows one device to replace multiple specialized devices, addressing the contradiction between versatility and complexity.
2Adaptability or versatility
If the alarm unit includes multiple light sources and functions, then it can operate effectively in both light and dark conditions, but the device size and weight increase
Solution Approach 1:
The patent employs thin-film LED technology for all light sources (visible strobe, infrared illumination, and flashlight). LEDs are inherently thin and lightweight compared to traditional bulb-based lighting systems, allowing multiple light functions to be integrated without significantly increasing the alarm unit's weight or size.
3Reliability
If the alarm provides both audible and visual signals, then it enhances detection capability, but it may alert intruders to the alarm's activation
Solution Approach 1:
The alarm unit emits different types of light with different properties: visible strobe light for general detection, infrared illumination for night vision compatibility, and a focused flashlight beam for directional signaling. This local quality differentiation allows the system to provide comprehensive detection while enabling selective signal emission based on operational requirements.
4Adaptability or versatility
If the alarm unit is designed for easy installation on various surfaces, then it increases adaptability, but the mounting mechanism becomes more complex
Solution Approach 1:
The alarm unit incorporates a universal adhesive mounting system that can attach to diverse surfaces (walls, windows, trees, rocks) without requiring surface-specific mounting hardware. This universal adhesive approach eliminates the need for complex mechanical mounting mechanisms while maintaining high mounting adaptability across different environments.
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 system provides a discreet and effective means of securing perimeters by combining audible and visual alarms with infrared capabilities, enabling detection without alerting others, and can be easily set up and adapted for different environments.
Implementation Method 1
The base unit can be adhesively mounted on almost any surface, such as a clean flat glass, plastic, wood or metal surface, with an adhesive provided on the back of the base unit
Implementation Method 2
The light pipe can include grooved or prism-shaped internal surfaces which efficiently direct light away from the base unit in a predetermined direction or directions
Implementation Method 3
A first press illuminates a fast strobing light which in one embodiment is a blue LED light
Data Source
AI summary
An alarm system includes a battery-powered base unit having an audible alarm, a switched constant on constant off light which can be used as a flashlight, and a strobed light providing a visible position indicator. The audible alarm and strobed light are activated simultaneously upon the release of a pull pin from a pair of electrical contacts within the base unit. The strobed light can be visible or infrared. A trip line can be connected to the pull pin to provide a secure line of entry or a secured enclosed area.
