RF-Powered Electronic Tag Eliminates Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display electronic tagging systems require battery replacement, which is inconvenient and burdensome, especially since battery power levels vary with usage, making management of multiple tags time-consuming and inefficient.
Innovation Solution
The system eliminates the need for a built-in battery by incorporating a wireless RF module, a display device, a power generator, and a capacitor, allowing electromagnetic induction to generate electricity from an external RF signal, which is stored in a capacitor for powering the display circuit, thus avoiding battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a built-in battery is used to power the display electronic tagging, then the display device can operate independently, but the battery requires periodic replacement and power management becomes complex
Solution Approach 1:
The patent removes the battery component from the display electronic tagging system entirely. Instead of having a built-in battery that requires replacement and management, the system uses an RF module to receive wireless power and data from an external source, eliminating the battery replacement burden and simplifying power management.
Solution Approach 2:
The RF module serves multiple functions: it acts as both a communication interface for receiving data and a power reception device. This multi-functionality replaces the separate battery-based power system, allowing the display electronic tagging to operate without a built-in battery while maintaining independent operation capability.
2Adaptability or versatility
If multiple display electronic tagging are managed with different battery power levels, then each tag can operate independently, but managing them becomes time-consuming and burdensome
Solution Approach 1:
By extracting the battery component from each display electronic tagging, the system eliminates the need to monitor and manage battery power levels across multiple tags. Each tag operates independently through RF power reception, and users no longer need to spend time managing battery status across multiple devices.
3Duration of action of stationary object
If a battery is used to power the display device, then the system can function without external power sources, but the battery will be exhausted and require replacement
Solution Approach 1:
The patent eliminates the battery by implementing an RF-powered system. The display electronic tagging continuously operates by receiving wireless power through the RF module, eliminating battery exhaustion and replacement needs while maintaining continuous operation capability.
Solution Approach 2:
The RF module acts as an intermediary between the external power source and the display device. Instead of storing power internally in a battery, the system uses the RF module to continuously receive and convert wireless power, enabling uninterrupted operation without battery replacement.
