Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security system physically secures the merchandise to prevent theft, then theft prevention is improved, but the ease of operation for potential purchasers deteriorates
Solution Approach 1:
The security system is divided into separate functional components: a sensor assembly that detects removal attempts, a flexible circuit that provides electrical connection, and a bracket that provides physical attachment. This segmentation allows the system to maintain security while enabling legitimate operations, as each component can be optimized independently for its specific function without compromising the others.
Solution Approach 2:
The sensor acts as an intermediary between the physical bracket and the alarm system. It monitors the engagement state of the bracket and triggers an alarm only when unauthorized removal is detected, thereby mediating between the need for physical security and the need to allow legitimate examination and operation of the merchandise.
2Reliability
If the sensor is permanently fixed to the bracket for reliable detection, then detection reliability is improved, but the ease of repair and replacement deteriorates
Solution Approach 1:
The connection between the sensor and bracket transitions from a static permanent bond to a dynamic removable connection. The sensor is designed to be releasably engaged with the bracket, allowing it to be easily removed and replaced while maintaining reliable detection functionality during normal operation. This dynamic connection enables both reliable detection and easy maintenance.
Solution Approach 2:
The sensor is designed as a replaceable component that can be easily discarded and replaced if malfunctioning or depleted. The releasable engagement mechanism allows quick removal of the sensor from the bracket without requiring complex disassembly, facilitating rapid replacement and minimizing downtime for the security system.
