Connector System Verification Mechanism for Secure Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems face challenges in ensuring secure communication and power transmission between devices, as they lack effective mechanisms to prevent unintended connections and ensure security against noise and unauthorized devices.
Innovation Solution
A connector system with a first and second transmission line, where the second connector performs an information transmission process to create verification information, and the first connector verifies the second connector based on this information, using a switch to control electrical connections, ensuring secure communication and power transmission by preventing connections with unintended devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector system allows automatic connection between devices, then connection speed and ease of operation improve, but security against unauthorized devices and noise interference deteriorates
Solution Approach 1:
The verification unit performs verification of the mating connector before the switch establishes electrical connection. This preliminary verification action ensures that only authorized connectors can establish connection, preventing unauthorized devices from connecting while maintaining fast connection speed for authorized devices.
Solution Approach 2:
The verification unit acts as an intermediary between the connector and the switch. It receives verification information from the mating connector, performs verification, and only then allows the switch to establish electrical connection. This intermediary mechanism ensures security while maintaining ease of operation.
2Reliability
If a verification process is added to ensure secure connection, then security and reliability improve, but device complexity and processing time worsen
Solution Approach 1:
The verification unit utilizes existing communication lines and processing units within the connector system to perform verification functions. By making existing components multi-functional (serving both data transmission and verification purposes), the system achieves enhanced security without significantly increasing device complexity.
3Speed
If electrical connection is established immediately upon connector engagement, then connection speed improves, but risk of communication with unintended devices increases
Solution Approach 1:
The verification of the mating connector is performed as a preliminary action before the switch establishes electrical connection for data and power transmission. This ensures that connection speed remains fast for authorized devices while preventing unauthorized communication by verifying authenticity first.
Solution Approach 2:
The verification unit receives verification information from the mating connector and provides feedback to the control unit, which then controls the switch accordingly. This feedback mechanism ensures that electrical connection is established only after successful verification, preventing unauthorized communication while maintaining fast connection for authorized devices.

AI summary
A connector system is provided with a first connector including a first transmission line, and a second connector including a second transmission line. The second connector includes a processing unit configured to perform an information transmission process of creating information regarding verification, and transmitting the information to the first connector. The first connector includes: a switch configured to, in a state where the first connector and the second connector are connected to each other, select whether or not to electrically connect the first transmission line and the second transmission line to each other; a verification unit configured to perform a verification process of verifying the second connector, based on the information received from the second connector; and a control unit configured to control the switch, based on a result of the verification process.
