Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional light beam security systems are used, then the system can detect intruders interrupting the beam, but the system components outside the secure area can be intercepted and replaced by intruders

Engineering Contradiction:

Improvesecurity detection reliabilityVSAvoidinterception and replacement vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces quantum entanglement as an intermediary mechanism between the sensing beam and reference beam. The entangled quantum states serve as a mediator that links the two beams, allowing the reference beam (inside secure area) to be correlated with the sensing beam (outside secure area). Any tampering with the sensing beam disrupts the quantum entanglement, providing detectable changes without requiring the entire system to be in the secure area.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the fundamental parameter of light from classical electromagnetic waves to quantum states (photons). By using quantum mechanical properties such as entanglement and superposition, the system transforms the sensing mechanism from classical light beam interruption detection to quantum state correlation verification. This parameter change makes the system inherently resistant to interception and replacement attacks.

If security systems require all components to be in a secure area, then tampering with components is prevented, but the monitored area and system complexity increase

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent divides the security system into two distinct segments: the sensing beam path (outside secure area) and the reference beam path (inside secure area). By segmenting the system and using quantum entanglement to correlate these segments, the patent allows critical detection components to remain in the secure area while extending the sensing capability outside the secure area without proportionally increasing the secure area size.

Core Design Contradiction:

Solution Approach 1:

The patent creates a quantum copy of the sensing beam path as the reference beam path. Through quantum entanglement, the reference beam serves as a correlated copy that remains inside the secure area. This copying approach allows the system to verify the integrity of the sensing beam without requiring physical access to the sensing path, thereby improving reliability while managing complexity through the use of standard quantum optical components.

AI summary

A security system uses a source capable of producing an entangled state of a sensing mode and a reference mode. The sensing mode has a path that enters an area around an object being secured. A state measurement system in the security system can measure a combination of the sensing mode after traversal of the sensing path and the reference mode after traversal of a reference path.
