Solution Overview

Problem

The existing electric actuator systems for hospital and care beds lack a secure and simple method for transferring network identification information, leading to potential accidental connections and safety risks when connecting the actuator systems to bed manufacturer's equipment.

Innovation Solution

Incorporating an RFID circuit within the actuator system to communicate network identification information, ensuring secure and proximity-based connections by using a unique code that can be read by bed manufacturer's equipment, with options for programming and placement on the operating device or a credit card-like format.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the MAC address is displayed on a label attached to the actuator system, then the network identification information is available for connection, but the connection process becomes complex and error-prone due to the long code and manual entry requirements

Engineering Contradiction:
Improvenetwork identification information transferVSAvoidconnection process
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical process of reading and entering the MAC address with an automated wireless communication system. The RFID reader automatically detects and retrieves the MAC address from the RFID tag, eliminating the need for manual transcription and reducing errors.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs the information transfer automatically without requiring user intervention. The RFID reader autonomously scans for the actuator system, retrieves the MAC address, and completes the connection process, making the system self-servicing for the connection task.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the actuator system allows broadcasting of MAC addresses for selection, then the connection process becomes simpler, but the risk of accidental connections to wrong actuator systems increases

Engineering Contradiction:
Improveconnection processVSAvoidaccidental connection risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary verification mechanism through the RFID system. Instead of direct connection based on broadcast addresses, the RFID reader acts as an intermediary that verifies the proximity and identity of the actuator system before allowing connection, preventing accidental connections to wrong systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements preliminary verification through RFID authentication before allowing connection. This preliminary check prevents harmful accidental connections by ensuring that only the intended actuator system can be connected to the terminal.

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If the RFID circuit read range is extended to over twenty centimeters, then the connection becomes more convenient, but the risk of accidental connections to other actuator systems increases

Engineering Contradiction:
Improveconnection convenienceVSAvoidaccidental connection risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the RFID read range parameter to a specific distance that balances convenience and safety. By carefully selecting the read range parameter, the system achieves sufficient connection convenience while maintaining safety margins to prevent accidental connections to other actuator systems.

Inventive Principle:
Principle #35Parameter changes

AI summary

A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system in the form of a gateway and a codex interprets the information in the bidirectional data stream and communicates the information on both sides. The communication system is furthermore provided with an RFID circuit integrated in a handset. The RFIC circuit can communicate information about the gateway's unique identification, also known as an MAC-address. This achieves easy connection of an external device to the actuator system without having to enter data manually.
