Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Datacenter floor tiles are often lifted without authorization, posing risks to the integrity of services and safety within the datacenter, as existing access control methods fail to prevent unauthorized access to business system infrastructure.

Innovation Solution

An intelligent datacenter floor system utilizing RFID tags and a tile lifter with RFID readers and an access control device, which compares PINs to access codes, generates an induction current to unlock or lock floor tiles based on authorization, ensuring only authorized personnel can lift specific tiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If floor tiles are made easily accessible for lifting, then ease of operation is improved, but security and protection of infrastructure deteriorates

Engineering Contradiction:

Improveease of lifting floor tilesVSAvoidunauthorized access to infrastructure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical access control (physical keys, locks) with an RFID-based electromagnetic system. The RFID reader in the tile lifter communicates with RFID tags in authorized personnel badges to authenticate users before enabling tile lifting, thereby maintaining ease of operation while improving security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an RFID authentication system as an intermediary between the operator and the floor tile lifting mechanism. The system verifies authorization credentials through RFID tags and mediates the lifting process by controlling the engagement between the tile lifter and floor tiles, preventing unauthorized access while maintaining operational efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If access control systems are implemented for floor tiles, then security is improved, but device complexity increases

Engineering Contradiction:

Improveprotection against unauthorized liftingVSAvoidcomplexity of access control system

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements a universal RFID authentication system that can be applied across multiple floor tiles throughout the datacenter. The same RFID reader and authentication protocol are used for every tile, eliminating the need for tile-specific complex mechanisms and reducing overall system complexity while maintaining security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs automatic authentication by reading RFID tags from authorized personnel badges without requiring manual intervention. The RFID reader automatically detects and verifies credentials, and the system self-manages the authorization process, reducing operational complexity while maintaining strong security controls.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If RFID authentication is required for tile lifting, then security is improved, but time for access control verification increases

Engineering Contradiction:

Improveprevention of unauthorized accessVSAvoidtime for authentication verification

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

Authorized personnel carry RFID badges that continuously broadcast their authentication credentials before approaching the tile lifter. The system is pre-configured with authorized RFID identifiers, enabling rapid verification as personnel approach, thereby minimizing authentication time while maintaining security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces time-consuming manual verification processes with rapid RFID electromagnetic authentication. The RFID reader can verify credentials in seconds compared to traditional manual checking methods, significantly reducing authentication time while maintaining or improving security levels.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method includes: reading, by a tile lifter, a radio-frequency identification (RFID) tag within a floor tile that is locked to a support structure; comparing, by the tile lifter, a personal identification number (PIN) of the RFID tag to an access code within the tile lifter; determining, by the tile lifter, a match between the PIN of the RFID tag and the access code; and actuating, by the tile lifter and in response to the determining the match, an actuator in the floor tile.
