Solution Overview
Problem
RFID chips lack necessary functionality due to their simple design, leading to increased manufacturing costs and rigidity when additional components are added to enhance functionality, which compromises the advantages of using RFID chips alone.
Innovation Solution
A printed circuit is developed where an RFID chip is electrically coupled with printed electronics, including a power source, antenna, and other components, all manufactured using a printing method, allowing for cost-effective and versatile circuits with reduced manufacturing costs by using cross-component layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components are added to RFID chips to enhance functionality, then functionality is improved, but manufacturing costs increase and the circuit becomes more rigid and fragile
Solution Approach 1:
The patent combines multiple circuit components (antenna, power source, electrical components) into a single integrated printed circuit structure. The RFID chip is mounted on a substrate that integrates the antenna pattern, power source, and electrical components as unified printed structures rather than separate discrete components, reducing overall circuit complexity while maintaining enhanced functionality.
Solution Approach 2:
The printed circuit substrate serves multiple functions simultaneously: it provides mechanical support for the RFID chip, contains the antenna pattern for wireless communication, houses the power source for energy storage, and incorporates electrical components for signal processing. This multi-functional integration avoids the need for separate discrete components.
2Adaptability or versatility
If additional components are added to RFID chips to enhance functionality, then functionality is improved, but manufacturing costs increase
Solution Approach 1:
Multiple components are merged into a single printed circuit manufacturing process. The antenna, power source, and electrical components are all created using printing techniques applied to the substrate in an integrated manner, allowing for cost-effective mass production rather than assembling separate expensive components.
Solution Approach 2:
The patent replaces traditional mechanical assembly processes with printing-based fabrication. Instead of mechanically assembling discrete components onto the RFID chip, all additional components are directly printed onto the substrate, simplifying the manufacturing process and reducing costs through a more streamlined production method.
3Adaptability or versatility
If discrete components are used to supplement RFID chip capabilities, then functionality is improved, but flexibility and advantages of RFID chips are reduced
Solution Approach 1:
The antenna, power source, and electrical components are merged into a unified printed structure on the substrate rather than using separate discrete components. This integration maintains the flexibility and simplicity advantages of RFID chips while providing enhanced functionality through the combined structure.
Solution Approach 2:
The printed circuit components are created as thin printed layers on the substrate, maintaining flexibility. The printed antenna, power source, and electrical components form thin-film structures that preserve the flexible nature of the overall RFID circuit assembly.

AI summary
A printed circuit including a non-conductive substrate, a first conductive layer printed on the non-conductive substrate and one or more additional layers printed on the substrate. The first conductive layer is able to have one or more antennas each forming a predetermined pattern, a first conductive sheet and one or more conductive traces. The one or more additional layers include a first electrode printed on the top of the first conductive sheet, a buffer printed on top of the first electrode, a second electrode printed on top of the buffer and a second conductive sheet printed on top of the second electrode. The printed circuit is further able to include an RFID chip electrically coupled with the antennas and at least one of the first and second conductive sheets via the conductive traces, wherein the first and second conductive sheets, the buffer and the first and second electrodes form a power source that provides electrical power to the RFID chip.
