Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock structures for electronic devices require inconvenient operations involving simultaneous manipulation of rotatable fasteners and key insertion, making them cumbersome to use for securing and detaching from electronic products.
Innovation Solution
A lock structure with a rotatable fastener and a lock body that includes a T-shaped retaining portion, an elastic element, and a gear rack-like driving portion, allowing for easy engagement and disengagement with a lock hole through a simple displacement mechanism, enabling quick and secure attachment and detachment of electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional lock mechanism with separate rotatable fastener and key operation is used, then the locking function is achieved, but the operation procedure becomes complex and inconvenient
Solution Approach 1:
The patent merges the rotatable fastener and lock body into a single integrated lock structure. The fastener includes both the rotating component and the locking mechanism within one unified body, eliminating the need for separate operations on distinct components. This integration allows users to perform locking and unlocking with a single rotational motion rather than coordinating multiple separate actions.
Solution Approach 2:
The lock structure is designed so that the fastener serves multiple functions simultaneously: it acts as both the rotating element for engagement/disengagement and the locking mechanism for securing the electronic device. The single lock body performs both fastening and locking operations, making the device more versatile and easier to operate.
2Productivity
If a lock structure with separate key hole operation is used, then security is provided, but the time required for locking and unlocking increases
Solution Approach 1:
The lock structure is pre-configured with the key hole and locking mechanism in fixed positional relationships. The fastener and lock body are designed with predetermined engagement features that automatically align when the fastener is rotated. This preliminary arrangement eliminates the need for manual alignment or complex coordination during operation, allowing users to lock or unlock the device quickly with a simple rotational motion.
3Ease of operation
If a rotatable fastener with T-shaped retaining portion is used, then easy engagement and disengagement is achieved, but the device structure becomes more complex
Solution Approach 1:
The fastener is segmented into distinct functional portions: the rotating portion for user operation, the T-shaped retaining portion for engagement with the lock hole, and the connecting portion linking these elements. This segmentation allows each component to perform its specific function efficiently while maintaining an overall simple and intuitive operation mechanism.
Solution Approach 2:
The T-shaped retaining portion is designed to protrude perpendicular to the rotation axis, creating a shape that naturally engages with corresponding features in the lock hole. This inverted T-shape configuration allows the fastener to be easily inserted and rotated into place, with the shape itself providing the locking action rather than requiring additional complex mechanisms.
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
The lock structure provides a secure and user-friendly solution by allowing for quick locking and unlocking operations, enhancing the convenience and efficiency of securing electronic devices without the need for complex manipulations.
Implementation Method 1
An elastic element is disposed on one end of the lock body. When operating the unlocking operation, the elastic element provides elasticity to push the lock body to displace by a second displacement toward the first opening and to drive the rotatable fastener to rotate to an unlocked position
Implementation Method 2
A gear rack-like driving portion is disposed on the lock body, while the driven portion of the rotatable fastener has a gear wheel-like structure. The driving portion and the driven portion are in contact with each other. When the lock body displaces by the first or the second displacement, the driving portion drives the driven portion and the rotatable fastener to rotate by means of matching up and engagement of the gear wheel-like and gear rack-like structures

AI summary
A lock structure for an electrical device includes a rotatable fastener and a lock body. The rotatable fastener has an extending portion and a retaining portion, wherein the extending portion and the retaining portion form a T-shaped structure; the lock body is connected to the rotatable fastener and has a key hole. The lock body further has a first position and a second position in a radial direction of the extending portion. The key inserted in the key hole operates the lock body to displace from the second position to the first position, wherein the lock body drives the rotatable fastener to rotate to an unlocked position. When the lock body is in the first position, the lock body is pressed to displace from the first position to the second position, wherein the lock body drives the rotatable fastener to rotate to a locked position.
