Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If demonstration models are made accessible for examination and operation, then customer ability to evaluate product is improved, but vulnerability to theft increases
Solution Approach 1:
The security system divides the protection function into separate components: a sensor module that detects removal attempts and a base unit that anchors the sensor. This segmentation allows the sensor to be lightweight and unobtrusive while the base provides secure anchoring, enabling customer access without compromising security.
Solution Approach 2:
The sensor acts as an intermediary between the merchandise and the security system. It detects unauthorized removal attempts and triggers an alarm without directly restraining the customer or the product, thus maintaining ease of operation while preventing theft.
2Reliability
If security measures are added to prevent theft, then security effectiveness is improved, but device complexity increases
Solution Approach 1:
The sensor and base are designed as integrated components that work together as a unified security system. The sensor engages with the base through simple mechanical and electrical connections, combining detection and anchoring functions without requiring complex assembly or multiple separate devices.
Solution Approach 2:
The sensor automatically detects removal attempts and triggers the alarm without requiring manual intervention from security personnel. The system is self-monitoring and self-activating, reducing the need for complex control systems while maintaining high security effectiveness.
3Reliability
If sensor engages rear and bottom surfaces of merchandise, then security coverage is improved, but device profile increases
Solution Approach 1:
The sensor is designed to engage the merchandise in multiple dimensions simultaneously - contacting both the rear surface and bottom surface of the device. This multi-dimensional engagement provides comprehensive security coverage while keeping the sensor itself compact and low-profile.
Solution Approach 2:
The sensor uses thin, flexible contact surfaces that can conform to the contours of the merchandise rear and bottom surfaces. This allows comprehensive engagement coverage while maintaining a minimalistic profile that does not significantly increase the overall device size.
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 effectively secures consumer electronics for display and testing, reducing theft risk by enabling power transfer and detecting unauthorized removal, while maintaining a minimalistic footprint and low profile.
Implementation Method 1
The base comprises a charging circuit for transferring power to the sensor and/or the item of merchandise via the electrical contacts when the sensor is supported on the base
Implementation Method 2
a cable connected to the sensor at one end and comprising at least one conductor for defining a sense loop for detecting removal of the cable or the item of merchandise from the sensor
