Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The continuous theft of UPS system batteries from radio-base stations poses significant challenges for telecommunication companies, leading to substantial losses, operational disruptions, and regulatory fines. Existing solutions, such as audible alarms and mechanical locks, are either inefficient or difficult to implement, as they either fail to deter theft effectively or complicate battery replacement and maintenance.

Innovation Solution

A comprehensive assembly and control system for electric accumulators in radio-base stations, featuring a processing center, electromagnetic locks, a backup power supply, presence sensors, and audible alarms. This system securely fixes batteries to racks using electromagnetic locks, ensures continuous power supply, and records maintenance and replacement actions electronically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical locks are used to fix the battery into the cabinet, then theft prevention is improved, but battery replacement and maintenance become difficult

Engineering Contradiction:

Improvetheft preventionVSAvoidbattery replacement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent uses electromagnetic locks instead of mechanical locks, allowing the locking mechanism to be dynamically controlled through electrical signals. The locks can be engaged to prevent theft and disengaged remotely or automatically to facilitate maintenance, resolving the contradiction between security and ease of replacement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces the mechanical locking system with an electromagnetic locking system. This substitution allows for easier control and operation, as the electromagnetic locks can be activated or deactivated through electrical control, making battery replacement simpler while maintaining theft prevention capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If resins are used to fix the battery into the cabinet, then theft prevention is improved, but implementation becomes difficult and replacement is prevented

Engineering Contradiction:

Improvetheft preventionVSAvoidimplementation difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces chemical fixation methods (resins) with electromagnetic locking mechanisms. This substitution eliminates the complexity of resin application and curing processes, making implementation easier while maintaining secure fixation and allowing for straightforward removal when needed.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Difficulty of detecting and measuring

If audible alarms are installed in distant RBSs, then theft detection is improved, but efficiency decreases due to difficult access

Engineering Contradiction:

Improvetheft detectionVSAvoidresponse efficiency

Core Design Contradiction:

Difficulty of detecting and measuringVSEase of operation

Solution Approach 1:

The patent incorporates sensors that detect battery removal attempts and provide feedback to a control system. When theft is detected, the system can trigger alarms and notify authorities remotely, improving detection efficiency without requiring physical access to distant locations for monitoring.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent uses electronic sensors and communication systems as intermediaries between the battery and the monitoring system. These intermediaries enable remote detection and reporting of theft attempts, eliminating the need for direct human presence at distant locations and improving response efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)
