Solution Approach 1:

The patent replaces wired electrical connection systems with wireless radiofrequency communication. RFID tags and antennas eliminate the need for physical electrical contacts, achieving catheter identification without compromising charger simplicity. This substitution maintains reliability while avoiding complex wired connections.

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

Solution Approach 2:

The patent introduces RFID tags as intermediary components that store catheter information and antennas as mediators that enable wireless communication between the catheter and charger. These intermediaries facilitate accurate catheter identification without requiring direct electrical connections, thus improving reliability while keeping the charger design relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If wired electrical connections are added to detect and identify catheters, then catheter identification capability is improved, but safety compliance may be compromised and device complexity increases

Engineering Contradiction:
Improvecatheter information detectionVSAvoidsafety compliance risk
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes wired electrical connections with wireless radiofrequency communication systems. RFID tags contain catheter information, and antennas wirelessly transmit this data without requiring electrical contacts. This eliminates safety compliance risks associated with wired connections while fully achieving catheter information detection.

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

3Adaptability or versatility

If a single charger is used for multiple catheter types without identification, then ease of operation is improved and device complexity is reduced, but measurement accuracy may be compromised due to unsuitable catheter usage

Engineering Contradiction:

AI summary

A charger for charging a plurality of pressure sensing catheters is provided. The charger has a plurality of charging ports of which a first charging port and a second charging port receives a first connector and a second connector respectively. The first and second connectors each have a first and second radiofrequency identification tags respectively, having information indicative of identifiable information of a first and second pressure sensing catheters respectively. The charger has a plurality of antennas, of which a first antenna and a second antenna can be positioned proximate to the first charging port, and second charging port respectively. When the first connector is inserted into the first charging port, the first radiofrequency identification tag is guided to a predetermined orientation with respect to the first antenna to minimize a spacing therebetween, and to maximize absorption of radiofrequency energy therebetween.
