Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Demonstration models of consumer electronics are vulnerable to theft due to their functionality allowing potential purchasers to examine and operate them, necessitating a security system that prevents unauthorized removal while allowing legitimate use.
Innovation Solution
A security system comprising a sensor with an inductive coil and electrical contacts that transfers power to the item when in contact with a base, ceasing power when lifted, combined with a recoiler cable and alarm mechanism to detect unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If demonstration models are made functional for customer examination, then ease of operation is improved, but vulnerability to theft increases
Solution Approach 1:
The security system divides the protection function into separate components: a sensor attached to the merchandise, a base with driving electronics, and a recoiler cable. This segmentation allows the functional demonstration model to remain operational while the security components work independently to prevent theft.
Solution Approach 2:
The sensor acts as an intermediary between the functional demonstration model and the security system. It detects when the item is removed from the base and triggers the alarm, allowing the model to be examined freely while secured against unauthorized removal.
2Object-affected harmful factors
If security restrictions are increased to prevent theft, then theft vulnerability is reduced, but ease of operation deteriorates
Solution Approach 1:
The security system provides self-service protection without interfering with normal operation. The sensor automatically detects removal attempts and triggers the alarm, while the inductive charging system automatically charges the item when on the base. No manual intervention is needed, and customers can examine items freely.
Solution Approach 2:
The system replaces mechanical security restrictions (such as physical locks or tethers that would prevent movement) with electronic detection and alarm mechanisms. This substitution maintains ease of operation while providing effective security through sensor detection and alarm notification.
3Ease of operation
If inductive charging is implemented to keep items powered, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The base serves multiple functions: it acts as both a security sensor station and an inductive charging station. The driving electronics in the base can energize the sensor's inductive coil for security detection while also providing power to the merchandise item, combining security and charging functions in a single device.
Solution Approach 2:
The system merges the security sensing function and the power charging function into a single integrated base unit. The sensor with its inductive coil serves dual purposes: detecting removal attempts and enabling wireless power transfer to the merchandise, reducing overall system complexity despite adding functionality.

Function Achieved in This Case
Effectively secures consumer electronics against theft by allowing examination and operation while reducing the likelihood of unauthorized removal, suitable for residential, commercial, and retail environments.
Implementation Method 1
The sensor includes an inductive coil, and the base includes 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.
