Electromechanical Battery Locking for UPS Cabinet Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery theft prevention systems for UPS systems in RBSs are inefficient, difficult to implement, and hinder maintenance, while mechanical locks complicate battery replacement.
Innovation Solution
An electromechanical locking system with remote release capability, using a lock that fixes the battery to a cabinet and can be activated or released via a smartphone application or monitoring center, allowing easy implementation and authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical locks are used to fix the battery to the cabinet, then theft prevention is improved, but battery replacement becomes difficult
Solution Approach 1:
The locking system transitions from a static mechanical lock to a dynamic electromechanical lock that can change state between locked and unlocked positions. The lock is actuated by a motor that rotates to engage or disengage the locking element, allowing the system to adapt between security mode (locked) and maintenance mode (unlocked) based on authorization.
Solution Approach 2:
The patent replaces the purely mechanical locking mechanism with an electromechanical system that uses an electric motor to actuate the lock. This substitution allows remote control capability and authorization verification while maintaining the mechanical locking function, thereby improving both security and ease of operation through electronic control interfaces.
2Reliability
If resins are used to fix the battery into the cabinet, then theft prevention is improved, but implementation becomes difficult and maintenance is hindered
Solution Approach 1:
The locking system is divided into separate modular components: the locking mechanism mounted on the cabinet, the battery with integrated lock engagement features, and the control system. This segmentation allows independent installation, replacement, and maintenance of each component without affecting the others, simplifying implementation and maintenance compared to resin bonding which creates a monolithic assembly.
Solution Approach 2:
The patent replaces the chemical bonding process (resin application and curing) with a mechanical electromechanical locking system. This substitution eliminates the complexity of resin application, positioning, and curing processes, while providing a reversible and controllable locking mechanism that is easier to implement and maintain.
3Reliability
If mechanical locks are positioned to prevent violation, then theft prevention is improved, but battery removal by technicians becomes difficult
Solution Approach 1:
The electromechanical lock acts as an intermediary between the security requirement and the maintenance requirement. It provides a controlled interface that can transition between secure locked state (preventing theft) and accessible unlocked state (allowing technician removal), mediated by authorization verification and remote control commands.
Solution Approach 2:
The locking system dynamically adjusts its state based on operational requirements. During normal operation, the lock is engaged to prevent theft. During maintenance operations, authorized technicians can remotely or locally command the lock to disengage, allowing easy battery removal. This dynamic behavior resolves the contradiction between secure positioning and easy removal.
