Phone Case Antenna System for Contactless Microcircuit Card Recharging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microcircuit cards with rechargeable batteries require cumbersome and inconvenient dedicated chargers for recharging, which is not user-friendly, especially since users often have a portable phone with a more capable battery and antenna.
Innovation Solution
A portable phone case with a flap housing a microcircuit card and contactless communication antennas that electrically connect to the phone's antenna, allowing energy transfer from the phone's battery to recharge the card's battery through the antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated charger with near field communication antenna is used to recharge microcircuit cards, then the card can be recharged, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines the card recharging function with the phone case structure. The phone case integrates a battery and near field communication antenna system that can recharge microcircuit cards directly within the case housing, eliminating the need for separate dedicated chargers. This merging of functions into a single integrated device reduces overall system complexity and improves ease of operation.
Solution Approach 2:
The phone case is designed to serve multiple functions: it protects the phone, provides additional battery power through its integrated battery, enables contactless communication through the NFC antenna, and can recharge microcircuit cards. This multi-functionality eliminates the need for separate dedicated card chargers, reducing device complexity while maintaining recharging capability.
2Adaptability or versatility
If a microcircuit card includes a rechargeable battery, then the card can function independently, but the card thickness increases
Solution Approach 1:
The patent extracts the heavy battery component from the microcircuit card and relocates it to the phone case. The card retains only the essential electronic circuit and near field communication antenna, making it thin and lightweight. The phone case battery assumes the power storage function, allowing the card to maintain independence for basic functions while achieving reduced thickness.
