Automatic Card Dispenser Handling Thick Active RFID Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic card dispensers are unable to efficiently issue thicker, heavier active RFID cards used for precision control and real-time tracking in security systems, as they often malfunction due to the size and weight of these cards.
Innovation Solution
An automatic card dispenser with a base, vertical lifting unit, horizontal pushing unit, recycling unit, and control unit, which includes a sensing unit and data accessing unit, allowing for precise card handling and dispensing without human supervision, capable of handling cards up to 8 cm×6 cm with a thickness of at least 0.2 cm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive RFID cards are used for security systems, then the card dispenser can handle them easily, but the system cannot achieve real-time tracking and precise information access
Solution Approach 1:
The patent changes the power supply parameter of the RFID card from passive to active, enabling the card to be powered continuously rather than only during reader proximity. This allows the card to transmit signals continuously for real-time tracking while maintaining a manageable size through efficient battery design
2Reliability
If active RFID cards are used for real-time tracking, then precision control and real-time tracking are achieved, but the cards become bigger, thicker and heavier causing dispensers to malfunction
Solution Approach 1:
The patent introduces a dynamic card pressing wheel that can adjust its pressing force and position based on the card's characteristics. This dynamic adjustment allows the dispenser to accommodate cards of varying sizes and weights, including thicker active RFID cards, without causing malfunctions or breakdowns
Solution Approach 2:
The dispensing mechanism is divided into separate functional units: a vertical lifting unit for elevating cards, a horizontal pushing unit for moving cards, and a card pressing wheel for controlling card ejection. This segmentation allows each unit to be optimized independently for handling different card types and sizes
3Productivity
If manual card dispensing is used, then card handling is simple, but security control efficiency is reduced and requires constant manpower
Solution Approach 1:
The patent implements an automated card dispensing system that operates independently without constant human intervention. The control unit automatically detects card presence, activates the vertical lifting unit to elevate cards, controls the horizontal pushing unit to move cards along tracks, and manages the card pressing wheel for ejection, enabling the system to serve itself
