Rotatable Fastener Lock Structure for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock structures for electronic devices are cumbersome and inconvenient to use, requiring simultaneous operation of multiple components for locking and unlocking, which complicates the process of securing and detaching the device.
Innovation Solution
A lock structure featuring a rotatable fastener with a T-shaped structure that aligns with a protruding portion on the housing, allowing for easy insertion and removal from a lock hole, and incorporating a combination or key lock mechanism that simplifies the locking and unlocking process through axial movement and rotation of the lock body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional lock structure requires simultaneous operation of rotatable fastener and lock body, then the locking function is achieved, but the ease of operation deteriorates
Solution Approach 1:
The patent combines the rotatable fastener and lock body into a single integrated component. The fastener includes a body portion that rotates within a housing and a retaining portion that extends outward, eliminating the need for separate operation of multiple components. This merging allows the user to perform locking and unlocking operations with a single rotational motion, directly improving ease of operation while maintaining secure locking function.
Solution Approach 2:
The integrated fastener structure performs multiple functions simultaneously: the body portion engages with the lock mechanism for securing, while the retaining portion provides external attachment points. The single component serves both as the locking element and the retaining element, allowing one operation to accomplish what previously required coordinated actions of separate components.
2Reliability
If a lock structure uses multiple separate components for locking, then the security is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges previously separate components (rotatable fastener and lock body) into a single integrated fastener assembly. This reduces the number of parts that need to be manufactured, assembled, and maintained, directly reducing device complexity while the retained security function is maintained through the engineered interaction between the body portion and housing.
3Ease of operation
If the lock fastener requires insertion and removal operations, then the ease of operation improves, but the time required for locking and unlocking increases
Solution Approach 1:
The fastener is pre-configured with the body portion and retaining portion in a specific geometric relationship. The body portion is positioned to engage with the lock mechanism upon rotation, and the retaining portion is oriented to provide attachment points. This preliminary configuration allows the fastener to transition directly from unattached to locked state through a single rotational motion, eliminating the need for separate insertion and removal steps and reducing the time required for locking and unlocking operations.

AI summary
A lock structure for an electrical device is provided. The lock structure includes a rotatable fastener, a lock body, an operation device, and a housing. The lock body is disposed at least partially in the housing, connected with the operation device, and couples with a driving portion. When the lock body is in an unlocked state, the lock body allows the driving portion to move the rotatable fastener. Simultaneously, the operation device can move the driving portion to change the orientation of the rotatable fastener, resulting in the connection/detachment of the lock structure and the electronic device. When the lock body is in a locked state, movement of the driving portion is restricted and the operation device cannot directly or indirectly rotate the rotatable fastener, resulting in the secure connection of the lock structure and the electronic device.
