Port Lock Unlocking Key With Pattern and Latch Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing port lock devices for electronic devices can be forcibly unlocked using unauthorized tools, compromising security, as they rely on pattern keys that can be partially inserted and manipulated to remove the locking member.
Innovation Solution
An unlocking key with a pattern key and latch key mechanism that securely fits into a key recess, featuring a movable housing and manipulation parts to ensure the locking module is only unlocked with an authorized key, preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple pattern key is used for unlocking the port lock, then the ease of operation is improved, but the reliability of security is worsened because the key can be partially inserted and forcibly manipulated to remove the locking member
Solution Approach 1:
The key recess is divided into two distinct functional areas: a pattern recess for pattern key insertion and a latch key holding recess for latch key retention. This segmentation ensures that the pattern key cannot be partially inserted to manipulate the locking member, as the latch key mechanism prevents such unauthorized operation while maintaining ease of legitimate unlocking.
Solution Approach 2:
The latch key acts as an intermediary component between the pattern key and the locking member. It must be properly engaged through the key recess before the pattern key can effectively unlock the device, preventing direct manipulation of the locking member and enhancing security reliability while preserving operational ease.
2Reliability
If a dedicated key with matching pattern is required for each lock device, then the reliability of security is improved, but the device complexity increases due to the need for specific key-lock pairing
Solution Approach 1:
The key recess is designed to accommodate both pattern key insertion and latch key holding within a single integrated structure. This multi-functional design allows the same key recess to serve multiple security functions without requiring separate mechanisms, thereby maintaining security reliability while minimizing device complexity.
Solution Approach 2:
The pattern recess and latch key holding recess are merged into a single key recess structure. This combination eliminates the need for separate key insertion points and simplifies the overall key-lock system, reducing device complexity while maintaining the security benefits of dedicated key pairing through the integrated dual-function recess design.

AI summary
An unlocking key for a port lock of an electronic device for unlocking and separating, from a port of the electronic device, a blocking module which is inserted and coupled to the port of the electronic device and has a key recess in which a pattern part and a latch key holding recess are formed on different inner surfaces of the key recess, includes a main body casing, a movable housing installed to protrude from a front end of the main body casing, a pattern key which is fixedly installed to protrude from a front end of the movable housing, a latch key which protrudes from the front end of the movable housing, and a manipulation part which is movably installed in the main body casing and controls reciprocating of the movable housing and opening and closing of the latch key.
