Solution Overview
Problem
Demonstration models of consumer electronics are prone to theft due to their use in retail displays, necessitating security systems that allow examination while minimizing theft risk.
Innovation Solution
A security system utilizing an inductive coil and sensor coupled to the merchandise, which transfers power inductively when the sensor is on a base, ceasing power transfer when lifted off, with a cable and base detecting unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security system is implemented to protect demonstration models from theft, then theft risk is reduced, but the ease of operation for examining the product is restricted
Solution Approach 1:
The patent replaces mechanical security systems (physical tethers, locks) with an electromagnetic field-based security system. The sensor detects the presence of the item through non-contact electromagnetic sensing, allowing customers to freely examine and operate demonstration models without physical constraints, while maintaining reliable theft prevention through automated detection and alarm systems.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the security system and the demonstration model. The sensor creates an electromagnetic field that detects the presence or absence of the item without direct physical contact, serving as a mediator that enables both free examination and secure monitoring simultaneously.
2Ease of operation
If a sensor with inductive coil is used to transfer power to the item of merchandise, then the item can be operated during display, but power transfer must be automatically ceased when the item is removed
Solution Approach 1:
The patent implements a feedback mechanism where the sensor continuously monitors the presence of the item of merchandise through electromagnetic coupling. When the item is detected as absent (indicating removal), the system automatically provides feedback to cease power transfer through the inductive coil, ensuring both continuous operation during display and reliable power cutoff when removed.
Solution Approach 2:
The patent establishes preliminary detection conditions where the sensor is pre-configured to detect the absence of the item before power cutoff occurs. The electromagnetic sensing field is maintained in readiness state, allowing immediate detection and automatic cessation of power transfer as soon as the item is removed, preventing any unauthorized power usage or theft.
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 secure display of merchandise by preventing theft through inductive power cutoff and alarm generation upon unauthorized removal, allowing examination and operation.
Implementation Method 1
The sensor includes at least one electrical contact and an inductive coil, and the base includes at least one electrical contact and driving electronics for the inductive coil. The sensor is configured to transfer power inductively to the item of merchandise when the at least one electrical contact of the sensor contacts the at least one electrical contact of the base to thereby allow the driving electronics to energize the inductive coil

AI summary
Embodiments of the present invention are directed to security systems for securing an item of merchandise from theft or unauthorized removal. For example, the security system may include a sensor configured to be coupled to the item of merchandise and a base configured to removably support the sensor and the item of merchandise thereon. The sensor includes at least one electrical contact and an inductive coil, and the base includes at least one electrical contact and driving electronics for the inductive coil. The sensor is configured to transfer power inductively to the item of merchandise when the at least one electrical contact of the sensor contacts the at least one electrical contact of the base to thereby allow the driving electronics to energize the inductive coil, wherein the sensor is configured to cease transferring power to the item of merchandise when the sensor is lifted off of the base.
