Protective Cover Elastic Arm Deflection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective covers for jack modules have complex locking structures and require complicated tools for removal, making them inconvenient to use for quick unlocking and removal.
Innovation Solution
A protective cover with an elastic arm and a removing tool that integrates unlocking and removing functions, using a cam surface and engaging units to deflect the elastic arm and facilitate easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective covers use complex locking structures to secure the jack module, then the protection reliability is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The protective cover is divided into a main body and multiple elastic arms that can independently engage with the jack module. Each elastic arm acts as a separate locking element, allowing the cover to maintain secure attachment through distributed engagement points rather than a complex integrated locking mechanism.
Solution Approach 2:
The elastic arms are designed to be deflectable, transitioning from a locked state (pressing against the inner wall surface) to an unlocked state (deflected away from the wall). This dynamic capability allows the same structure to provide secure locking during normal use while enabling easy removal when needed, without requiring complex locking mechanisms.
2Reliability
If conventional protective covers use complex locking structures to secure the jack module, then the protection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The elastic arms automatically return to their locked position against the inner wall surface when the protective cover is inserted into the jack module, providing self-locking functionality. This eliminates the need for complex manual locking operations while maintaining secure attachment, and the same elastic arms can be easily deflected for removal.
3Ease of operation
If a removing tool is designed with separate unlocking and removing functions, then the device complexity increases, but the ease of operation deteriorates
Solution Approach 1:
The removing tool integrates two functions into a single structure: the cam surface deflects the elastic arm to unlock the protective cover, while the engaging unit simultaneously grasps the cover for removal. This merging of unlocking and removing functions into one tool simplifies the user operation and reduces the number of separate components needed.
Solution Approach 2:
The removing tool is designed with multi-functionality, where a single tool structure performs both the unlocking action (via cam surface) and the removal action (via engaging unit). This universal design allows one tool to handle the complete removal process without requiring separate specialized tools for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and simplified operation for users to quickly unlock and remove the protective cover from the jack module, providing effective protection against foreign matters and unauthorized connections.
Implementation Method 1
at least one elastic arm being obliquely arranged in the main body and having a first engaging unit provided thereon; the elastic arm being normally pressed against an inner wall surface of the jack module to lock the protective cover to the jack module; the elastic arm being deflectable to unlock the protective cover
Implementation Method 2
having a cam surface and a second engaging unit from front to rear of the arm; whereby when the protective cover being unlocked and removed from the jack module, the cam surface of the arm being used to deflect then unlock the protective cover from the jack module

AI summary
A protective cover for locking to a jack module includes a main body for inserting into the jack module and having two openings, and two elastic arms for locking the protective cover to the jack module and having a first engaging unit each. A removing tool for unlocking and removing the protective cover from the jack module includes a handle portion and two arms. The arms respectively include a front cam surface for inserting into the main body to deflect the elastic arms and unlock the protective cover from the jack module, and a second engaging unit formed behind the cam surface for engaging with the first engaging unit, allowing a user to remove the protective cover from the jack module. The protective cover and removing tool respectively integrate the unlocking and removing functions into one structurally simplified device and is more convenient for use.
