Solution Overview
Problem
The packaging of mass-customized items, such as dental aligners, is labor-intensive and lacks efficiency, requiring automated systems to ensure accurate sequencing and identification in packaging.
Innovation Solution
A system comprising a database for item identification, an outer container identification apparatus, and a filling apparatus that matches items with their corresponding containers based on unique identification information, ensuring proper sequencing and packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual packaging operations are used for mass-customized items, then flexibility in handling unique items is maintained, but productivity is low and labor intensity is high
Solution Approach 1:
The system enables self-service packaging by using RFID tags on items and containers that automatically exchange identification data without human intervention. The database automatically matches items to containers based on their unique identifiers, eliminating the need for manual scanning and data entry while maintaining high productivity.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated information-based system. RFID readers automatically detect and read identification data from tags, and the database system automatically processes matching logic, substituting human cognitive and manual operations with electronic information processing.
2Productivity
If automated packaging systems are implemented, then productivity increases, but system complexity increases
Solution Approach 1:
The RFID tags and readers provide universal identification functionality that works across all item types and container types. The database system serves multiple functions including data storage, matching logic, and sequencing control, reducing the need for separate specialized systems for each function.
Solution Approach 2:
The database acts as an intermediary between RFID readers and the packaging execution system. It centralizes the matching logic and sequencing decisions, simplifying the control architecture by providing a single point of coordination rather than requiring complex direct communication between multiple sensors and actuators.
3Manufacturing precision
If items are packaged in predetermined sequence, then accuracy of sequencing is improved, but time for sequencing operations increases
Solution Approach 1:
The system performs preliminary sequencing by storing the correct sequence information in the database before packaging begins. RFID tags on items and containers are read in advance, and the database pre-calculates the matching sequence, so that during actual packaging, items are simply placed in pre-determined positions without real-time decision-making delays.
Solution Approach 2:
The RFID reading system provides immediate feedback on item and container identification, allowing the database to verify matches and detect sequencing errors in real-time. This feedback mechanism ensures sequencing accuracy while maintaining speed by automatically correcting deviations from the predetermined sequence.

AI summary
A system for packaging mass-customized items includes a computer system including a database containing item identification information unique to each item; (2) outer container identification apparatus that applies the item identification information received from the database to each outer container in a plurality of outer containers; (3) inner pack identification apparatus that applies the item identification information received from the database to each inner pack in a plurality of inner packs; and (4) inner pack filling apparatus that fills each inner pack with a specific item matched to that inner pack by the item identification information received from the database. Each item is associated with its unique item identification information and is inserted into an inner pack with matching item identification information, and each outer container is presented for loading with one or more inner packs matched to that outer container by the item identification information received from the database.
