Rotating Sleeve Locking Mechanism for Wearable Lanyards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lanyard connections for smart wearable devices are inconvenient for operation and replacement, and hanging objects are prone to falling off, due to lack of secure locking mechanisms.
Innovation Solution
A locking device comprising a sleeve, a locking assembly, and a stopper, where the sleeve rotates to switch between different gaps to lock or unlock the hanging member, utilizing stopping holes and a resilient member to secure the hanging member in place, preventing it from falling off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple lanyard connection is used, then the device structure is simple, but the hanging object is prone to fall off and replacement is inconvenient
Solution Approach 1:
The locking device is divided into distinct functional components: a locking assembly with movable locking members, a sleeve with stopping holes, and a resilient member. This segmentation allows each component to perform its specific function while maintaining overall structural simplicity, resolving the contradiction between simple structure and reliable locking.
Solution Approach 2:
The locking members are designed to be movable rather than fixed, allowing them to transition between locked and unlocked positions. The resilient member provides dynamic force to maintain the locking members in their proper positions, enabling reliable locking while keeping the structure simple and operable.
2Reliability
If a secure locking mechanism is added, then the hanging object is securely locked, but the operation and replacement become more complex
Solution Approach 1:
The resilient member automatically pushes the locking members into the locked position, and the sleeve's rotation automatically switches between stopping holes to engage or disengage the locking members. This self-service mechanism eliminates the need for complex manual operations while maintaining secure locking, thereby improving ease of operation.
Solution Approach 2:
The movable locking members and rotating sleeve create a dynamic system where locking and unlocking are achieved through simple rotational motion. The stopping holes provide discrete positioned states, making the operation intuitive and convenient while ensuring reliable locking when engaged.
3Device complexity
If the locking assembly is fixed in the sleeve, then the structure is simple, but the sleeve cannot rotate to switch between stopping holes
Solution Approach 1:
The locking assembly is designed with movable locking members that can shift position in response to sleeve rotation. The resilient member provides the necessary force to move the locking members between engaged and disengaged states, enabling the sleeve to rotate and switch between stopping holes while maintaining structural simplicity.
Solution Approach 2:
The resilient member acts as an intermediary between the rotating sleeve and the locking members. It translates the rotational motion of the sleeve into linear motion of the locking members, allowing the sleeve to rotate freely while the locking members respond appropriately to engage or disengage, thus providing both simplicity and versatility.

Function Achieved in This Case
Enables easy assembly and disassembly of smart wearable devices by rotating the sleeve, ensuring the hanging member is securely locked, preventing accidental detachment and enhancing user convenience.
Implementation Method 1
a resilient member, both ends of which are respectively arranged on the inner wall of the second mounting groove and the stopping block, and a restoring force is provided to the stopping block under pressure of the inner wall of the sleeve

AI summary
A locking device includes a sleeve, a locking assembly, and a stopper. The sleeve defines a locking cavity and stopping holes. The locking assembly includes a locking member received in the locking cavity and is rotatable relative to the sleeve to lock a hanging member in the sleeve or release the hanging member from the sleeve. The stopper and the stopping holes cooperate to position the locking member relative to the sleeve.
