Solution Overview

Problem

Existing printer/card charger assemblies are bulky due to the size requirements for card handling operations, making them large and inefficient, especially when multiple card feeders are used.

Innovation Solution

Implementing movable drive devices, such as rollers, that occupy spaces during card transfer operations, allowing the printer to utilize these spaces for handling cards, thereby reducing the overall size of the printer/card feeder assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the card feeder and output tray are positioned adjacent to the printer for card handling operations, then the printer can perform card manipulation operations, but the overall footprint of the printer/card feeder assembly becomes large

Engineering Contradiction:
Improvecard handling capabilityVSAvoidfootprint
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The drive devices are made movable between a transfer position (for card transfer from loading device to printer) and a retracted position (out of the way during printer operations). This dynamic positioning allows the printer to use the space occupied by the drive devices during card manipulation, reducing the overall footprint while maintaining full card handling capability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The card feeder system is divided into separate functional modules: loading devices, movable drive devices, and the printer. The drive devices can be independently positioned between transfer and retracted locations, allowing spatial separation of functions that reduces the overall assembly footprint

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple card feeders are used to supply cards to the printer, then the printer can handle multiple card decks, but the bulk and size of the printer/card feeder assembly increases

Engineering Contradiction:
Improvemulti-deck capabilityVSAvoidassembly bulk
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The movable drive devices serve multiple functions: they transfer cards from either the first or second loading device to the printer, and they can be retracted to allow the printer to perform operations. This multi-functionality allows multiple card decks to be supported without proportionally increasing the assembly bulk

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The drive devices are positioned in three-dimensional space such that they can occupy different positions (transfer position and retracted position) along the card transfer path. This spatial arrangement in multiple dimensions allows multiple loading devices to share the same physical envelope, reducing overall assembly bulk

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the drive devices remain stationary during card transfer, then the card transfer path is stable, but the printer cannot utilize the space occupied by the drive devices for card manipulation operations

Engineering Contradiction:
Improvecard transfer stabilityVSAvoidavailable space for printer operations
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The drive devices are designed to be movable rather than stationary, allowing them to be positioned in a transfer location during card transfer operations (providing stability when needed) and retracted to a different location during printer operations (freeing up space when needed). This dynamic positioning resolves the contradiction between stability and space utilization

Inventive Principle:
Principle #15Dynamics

AI summary

A card loader is intended to be fixed to a printer (23), the loader comprising at least one loading device intended to hold at least one card to be printed, and at least one driving device (16; 19). Each driving device (16; 19) transfers the cards to be printed from a loading device to the printer (23). At least one driving device (16; 19) is able to move in order to allow the printer (23), or one said loading device, to use, in order to manipulate a card, a space which is occupied by said driving device(s) (16; 19) when said driving device(s) (16; 19) is/are transferring a card to be printed to the printer.
