Drawer Slide Electronic Lock Mechanism for Secure Cabinet Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drawer slides provide easy access, which is not secure for valuable or personal items, and secure storage solutions like safes are bulky and not suitable for cabinet integration, especially when frequent controlled access is required.
Innovation Solution
An electronically actuated lock mechanism integrated into the drawer slide, featuring a housing with a latch receiver, lever arm, electrically actuated actuator, and microprocessor to control the locking and unlocking of the drawer, allowing for secure and controlled access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drawer slides provide easy access to contents, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent replaces traditional mechanical locking systems with an electronically actuated locking mechanism that integrates into the drawer slide. The electronic actuator controls a lever arm that can block or allow rotation of the latch receiver, providing secure locking while maintaining the smooth mechanical operation of the drawer slide. This substitution enables both easy access (when unlocked) and security (when locked) within the same slide mechanism.
Solution Approach 2:
The patent merges the locking mechanism directly into the drawer slide structure itself, rather than adding a separate lock to the drawer. The actuator, lever arm, and latch receiver are integrated components that work together within the slide assembly. This merging allows the locking function to be seamlessly combined with the sliding function, providing both security and ease of operation from a single integrated system.
2Reliability
If secure storage solutions like safes are used, then security is improved, but device complexity and bulk are worsened
Solution Approach 1:
The patent embeds the locking mechanism components within the existing drawer slide structure. The actuator, lever arm, and latch receiver are nested within the housing of the drawer slide, utilizing the available space efficiently. This nesting approach provides secure storage functionality without adding external bulk, as the security mechanism is contained within the profile of the drawer slide itself.
Solution Approach 2:
The drawer slide is designed to perform multiple functions: it provides the primary sliding mechanism for drawer extension, incorporates the locking mechanism for security, and includes electronic actuation for controlled access. This multi-functionality eliminates the need for separate safe structures, as the drawer slide itself becomes a secure storage solution that combines sliding, locking, and electronic control in a single universal component.
3Reliability
If an electronically actuated lock mechanism is integrated into the drawer slide, then security is improved, but device complexity is worsened
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the electrically actuated actuator, the lever arm, the latch receiver, and the housing. Each component has a specific function and can be analyzed independently. The lever arm acts as a cam that blocks or allows rotation of the latch receiver based on its position, controlled by the actuator. This segmentation makes the complex electronic locking system manageable and maintainable while providing robust security.

AI summary
An electrically actuated locking mechanism may include a microprocessor for control of the locking mechanism, and the locking mechanism may be used to lock a drawer slide in a closed position. The microprocessor may be in a housing of the locking mechanism, and the microprocessor may command a motor to operate in a first direction to drive lock components to a locked status and command the motor to operate in a second direction to drive the lock components to an unlocked state.
