Network Port Block-out Lock with Eccentric Removal Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network port locks are prone to damage and inefficient due to the use of tweezers for removal, which can cause improper pulling angles and forces, leading to unauthorized access and security concerns in internet networks.
Innovation Solution
A block-out lock and removal key system featuring a locker with a semicircular through hole and a latch body with a displaceable piece, combined with a key having an eccentric block for smooth operation, allowing precise engagement and rotation to unlock network ports without damaging the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tweezer-based removal tool is used to remove the block-out cover, then the cover can be removed from the jack module, but the device may be damaged due to improper pulling angle and forces
Solution Approach 1:
The patent introduces a dedicated removal tool with a specific geometric shape that acts as an intermediary between the user and the block-out cover. This tool engages with a corresponding feature on the cover, providing a controlled mechanical advantage and proper leverage point. The tool's design ensures force is applied at the correct angle and location, preventing damage to the jack module while enabling effective cover removal.
2Reliability
If a conventional lock mechanism is used without proper engagement features, then the locking function is provided, but the unlocking operation becomes difficult and may cause damage
Solution Approach 1:
The patent employs asymmetric design in both the block-out cover and removal tool. The cover includes a specifically shaped engagement feature that does not symmetrically match general shapes, while the removal tool has a corresponding asymmetric geometry. This asymmetric pairing ensures that only the correct tool can properly engage and remove the cover, providing security against unauthorized removal while enabling easy removal by authorized users with the correct tool.
3Reliability
If the block-out cover is designed to fit tightly in the jack module, then unauthorized access is prevented, but the cover becomes difficult to remove without special tools
Solution Approach 1:
The patent incorporates a pre-designed removal feature integrated into the block-out cover itself during the manufacturing process. This preliminary action embeds the engagement point for the removal tool directly into the cover structure, so that when installation is needed, the cover is already prepared for secure mounting, and when removal is needed, the pre-formed feature enables tool engagement without requiring any additional components or complex mechanisms.

AI summary
A block-out lock and removal key includes a locker and a key. The locker has a hollow housing in a shape corresponding to a socket of a network port for engagement, a locker hole extending through a front portion of the housing and a latch body connecting to a rear portion of the housing. The latch body has a rear section extended upwards toward the front portion of the housing and then downwards to form a displaceable piece parallel with the front portion of the housing with a holding section at a top of the displaceable piece and a block facing toward an inner end of the locker hole. The key has its front section arranged correspondingly to a shape of the locker hole to be inserted therein and rotated for unlocking. An eccentric block is further arranged at the front section of the key correspondingly to the block on the displaceable piece for removing the locker from the socket of the network port in operation.
