Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart card systems require users to replace readers or cards to accommodate contact or contactless functionality, making it impractical to upgrade or expand installations without replacing existing infrastructure.
Innovation Solution
A portable adaptor that allows a contact smart card to be used with a contactless smart card reader and vice versa, by providing a casing with external and internal modules for signal interfacing and signal boosting or limiting, enabling physical and electromagnetic signal conversion between different smart card formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contact or contactless smart card readers are replaced to accommodate different card types, then compatibility between contact and contactless cards is improved, but infrastructure cost and complexity increase
Solution Approach 1:
The patent introduces an adaptor as an intermediary device that physically connects to the existing reader and interfaces with the smart card. The adaptor contains the necessary contact pads or antenna elements to bridge between contact and contactless communication protocols, allowing the original reader to work with both card types without modification
Solution Approach 2:
The system is divided into separate functional components: the existing reader, the adaptor module, and the smart card. This segmentation allows the adaptor to be independently designed with specific contactless infrastructure elements (antenna, RF circuitry) while the original reader remains unchanged, reducing overall system complexity
2Adaptability or versatility
If all users' smart cards are replaced with contactless cards, then contactless functionality is improved, but user cost and deployment complexity increase
Solution Approach 1:
Rather than replacing cards, the adaptor acts as an intermediary that attaches to the existing contact card and provides contactless functionality. This allows users to retain their original cards while gaining access to contactless readers through the adaptor module
Solution Approach 2:
The adaptor effectively creates a contactless interface layer that copies or emulates the functionality of a contactless card to the reader, allowing contact cards to communicate with contactless readers without requiring actual contactless card hardware in the user's possession
3Stability of the object's composition
If contact smart card readers are used with contactless smart cards, then contact card reader functionality is maintained, but signal interface compatibility deteriorates
Solution Approach 1:
The adaptor serves as a signal interface intermediary that contains both contact pads for connection to the reader and an integrated antenna with RF circuitry for contactless communication. It translates between the contact-based electrical signals from the reader and the electromagnetic signals required by contactless cards
Solution Approach 2:
The adaptor changes the signal transmission parameters by converting electrical contact signals into electromagnetic radio frequency signals. The adaptor's RF circuitry modulates the contact signals onto an electromagnetic carrier wave, enabling compatibility between contact readers and contactless cards through parameter transformation

Implementation Method 1
means adapted for interfacing a contactless smart card placed in or near the adaptor with the contact smart card reader... for converting electrical signals received by the external contact module to electromagnetic signals
Implementation Method 2
means for boosting or limiting a level of electrical or electromagnetic signals transmitted between the contact smart card reader and the contactless smart card
