Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive near field communication (NFC) devices are inefficiently powered by mobile electronic devices, leading to rapid battery drain as they are charged to maximum capacity, which reduces the battery life of the mobile device.
Innovation Solution
A device with a module configured to exchange data and transmit energy to an NFC device, determining the energy difference needed for a specific function and transmitting only that amount, rather than fully charging the NFC device, thereby extending the battery life of the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile electronic device charges the NFC device to maximum capacity, then the NFC device is reliably powered, but the battery life of the mobile device is reduced
Solution Approach 1:
The system transmits only the necessary amount of energy required for the NFC device to perform its specific function, rather than charging it to maximum capacity. The processor calculates the energy difference between the current energy level and the required energy level, and transmits only that difference, thereby avoiding excessive energy consumption from the mobile device's battery.
Solution Approach 2:
The system dynamically adjusts the energy transmission parameters based on the actual needs of the NFC device. By monitoring the current energy level and comparing it with the required energy level for the specific function, the system optimizes the energy transmission amount, thus resolving the contradiction between providing sufficient power and conserving mobile device battery life.
2Reliability
If the mobile electronic device transmits maximum energy to the NFC device, then the NFC device has sufficient energy for any function, but energy is wasted when full capacity is not needed
Solution Approach 1:
The system transmits only the necessary amount of energy required for the NFC device to perform its specific function, rather than charging it to maximum capacity. The processor calculates the energy difference between the current energy level and the required energy level, and transmits only that difference, thereby avoiding excessive energy consumption from the mobile device's battery.
Solution Approach 2:
The NFC device provides feedback about its current energy level to the mobile electronic device. The processor uses this feedback information to determine the exact amount of energy needed and adjusts the transmission accordingly, preventing energy waste while ensuring the NFC device has sufficient energy for its intended function.
