Solution Overview
Problem
Existing systems fail to detect poor-contact sockets during manufacturing, leading to potential electrical arcs and fires, as they can only identify perfect or non-contact connections, not irregular contacts.
Innovation Solution
A memristor-based system comprising an AC socket connection, a side pad for tracking AC line voltage or current changes, a series resistor for current limiting, and a microprocessor unit for alerting poor-contact conditions by comparing memristance values with a reference, integrated with electronic devices for socket failure detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detection systems are used during manufacturing, then production speed is maintained, but poor-contact sockets cannot be detected leading to safety hazards
Solution Approach 1:
The patent replaces conventional mechanical/contact-based detection systems with a memristor-based electrical detection system. The memristor detects poor-contact conditions by measuring changes in electrical characteristics (memristance) rather than relying on mechanical contact verification, enabling detection of irregular contacts that mechanical systems miss while maintaining production speed
Solution Approach 2:
The invention utilizes changes in memristance parameter to detect poor-contact conditions. By monitoring the memristance value variations caused by irregular socket connections, the system can identify poor-contact sockets without requiring complex mechanical verification, thus improving reliability while keeping the detection mechanism relatively simple
2Productivity
If uninterrupted electricity is used during production testing, then manufacturing efficiency is maintained, but poor-contact conditions remain undetected
Solution Approach 1:
The patent enables continuous detection during uninterrupted power supply by using the live electrical current itself as the detection medium. The memristor continuously monitors electrical characteristics during normal operation without interrupting power flow, maintaining manufacturing efficiency while achieving accurate detection of poor-contact conditions through ongoing electrical parameter measurement
3Device complexity
If simple connect/non-contact detection is implemented, then device complexity is minimized, but poor-contact sockets causing electrical arcs cannot be identified
Solution Approach 1:
The patent introduces the memristor as an intermediary detection element between the power supply and the load. This intermediary component subtly monitors electrical characteristics without significantly altering the circuit's overall simplicity, enabling detection of poor-contact conditions that lead to electrical arcs while maintaining relatively simple circuit implementation
