Vacuum Waste Inlet Access Control via RFID Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waste fraction management systems face challenges in efficiently and cost-effectively handling multiple waste fractions, particularly smaller fractions like batteries and hazardous waste, due to the need for separate inlets and complex handling processes, which are economically and technically impractical.
Innovation Solution
A vacuum operated waste collection system utilizing a common waste inlet with information reading means to identify and manage multiple waste fractions based on a preset time schedule, allowing access only during designated times, and temporarily storing packages above a discharge valve for controlled conveyance to a shared collection container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate waste inlets are provided for different waste fractions, then waste fraction separation is improved, but device complexity and investment costs increase
Solution Approach 1:
The patent implements a single common waste inlet that serves multiple waste fractions through temporal separation. The inlet is equipped with information reading means (RFID readers, barcode scanners) and control means that identify waste packages and control access based on preset schedules, allowing one inlet to handle multiple fractions sequentially rather than requiring separate inlets for each fraction type.
Solution Approach 2:
The system uses information reading means to identify waste packages before they enter the inlet. RFID tags or barcodes on waste packages are read and verified against a preset fraction time schedule, allowing the control means to preemptively open or close the inlet door based on the identified fraction type and current time, preventing mixed waste entry before it occurs.

3Ease of operation
If access to waste inlet is always allowed, then ease of operation is improved, but waste fraction mixing occurs
Solution Approach 1:
The system uses information reading means to identify waste packages before they enter the inlet. RFID tags or barcodes on waste packages are read and verified against a preset fraction time schedule, allowing the control means to preemptively open or close the inlet door based on the identified fraction type and current time, preventing mixed waste entry before it occurs.
Solution Approach 2:
The control means continuously monitors the identified waste fraction type and compares it with the current time against the preset schedule. This feedback mechanism automatically adjusts the inlet door state (open/closed) in real-time based on whether the current fraction type is permitted at the current time, ensuring separation reliability while maintaining ease of operation for authorized waste types.

AI summary
In a method for managing waste (W) deposited in disposal packages (6-F1, 6-F2, 6-F...6-Fn ) and introduced into a vacuum operated waste collection system (1) wherein waste is conveyed through transport piping (3), from waste inlets (2) to a waste collection container (5) for storing waste before removal and wherein the disposal packages carry readable information (7-F1, 7-F 2, 7-F 3...7-Fn ), disposal packages containing one of multiple waste fractions (F1, F2, F...Fn ) are received through a common waste inlet, subsequent to identifying each disposal package by comparing read waste fraction information carried thereby and being unique for each fraction, with stored fraction data, comparing the identified disposal packages to a fraction time schedule for matching package information to fraction time schedule time periods belonging to the respective fraction, whereby access to the waste inlet is allowed for each package during the time periods belonging thereto and is blocked for each package at all other times.
