Portable Alarm Sensor Unit Wireless RF Transceiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems for protecting objects from unauthorized movement or theft are typically localized and non-portable, lacking remote monitoring capabilities, making it difficult for users to track and retrieve their valuables when they are moved or taken.
Innovation Solution
A portable alarm system comprising a sensor unit integrated with a transceiver, which can be attached to or embedded within an object, and a remote unit that alerts the user via RF signals if the object is vibrated, lifted, or moved beyond a trigger level, allowing for remote monitoring and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing alarm systems are used, then objects can be protected from unauthorized movement, but the systems are localized and non-portable, making it difficult to remotely monitor objects when they are moved or taken
Solution Approach 1:
The alarm system is divided into two separate portable components: a sensor unit that attaches to the object being protected, and a remote unit that the user carries. This segmentation allows the sensor unit to remain with the object while the user receives alerts remotely, resolving the contradiction between reliable object protection and remote monitoring capability.
Solution Approach 2:
A wireless communication intermediary (RF transceiver) is introduced between the sensor unit and the remote unit. This intermediary enables the sensor unit to transmit alarm signals to the remote unit without physical connection, allowing the system to be portable while maintaining reliable object protection and remote monitoring capabilities.
2Reliability
If existing alarm systems are used, then objects can be protected, but the systems require hard-wiring and cannot be easily moved between objects
Solution Approach 1:
The mechanical hard-wiring system is replaced with a wireless RF communication system. The sensor unit and remote unit communicate wirelessly, eliminating the need for physical connections and enabling easy portability between different objects while maintaining reliable object protection.
Solution Approach 2:
The system is segmented into a portable sensor unit that attaches to objects and a separate remote unit. This segmentation removes the constraint of hard-wiring, allowing the sensor unit to be easily moved between different objects while maintaining protection reliability.
3Adaptability or versatility
If portable sensor unit with transceiver is integrated, then remote monitoring capability is improved, but device complexity increases
Solution Approach 1:
The sensor and RF transceiver are merged into a single integrated sensor unit, eliminating the need for separate wiring and control components. This integration reduces device complexity while maintaining remote monitoring capability through wireless communication.
Solution Approach 2:
The sensor unit autonomously detects object movement and automatically transmits alarm signals via the integrated transceiver. This self-service capability eliminates the need for complex external control systems, reducing overall device complexity while enabling remote monitoring.
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
Enables users to remotely monitor and receive alerts about the movement or theft of objects, providing a portable and versatile solution for protecting a wide range of items, including vehicles, electronics, and personal belongings, with the ability to be easily moved between objects without the need for hard-wiring.
Implementation Method 1
The sensor unit may sense vibration, noise, or motion imparted on its sensors and thereby on the object as well
Implementation Method 2
the sensor unit transmits an alarm signal, preferably as a Radio Frequency (RF) signal, from the object's location to the remote unit carried on the person of the user

AI summary
A portable alarm system for notifying a user of theft or movement of an object when the user is at a distance from the object. The portable alarm system may generally comprise a sensor unit and a remote unit. The sensor unit may be placed on or embedded within an object to be protected and have one or more sensors for detecting vibration and/or motion of the sensor unit and thereby the object. The sensor unit is activated when vibration or movement input exceeds a predetermined trigger level value. When the trigger level value is exceeded, an alarm signal is transmitted to the remote unit. The remote unit receives the alarm signal and may generate one or more alarms to indicate object vibration or movement. The one or more alarms may include but are not limited to an audible buzzer, light indicators, and remote unit vibration.
