Modular Card Processing Unit Layout Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card processing units require redesigning and increased design costs when modifying the number of card stack parts or their arrangement, as the card stack and moving parts are integrally assembled, making layout adjustments cumbersome.
Innovation Solution
A card processing unit with a modular card stack part that can be separated from the card feeding part, allowing for independent mounting and easy reconfiguration, featuring a card ejection mechanism, cassette system, and control board connectivity for unified functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If card stack parts and card taking and moving part are integrally assembled in sub-frame, then structural stability is improved, but layout flexibility deteriorates
Solution Approach 1:
The patent divides the card issuing unit into separate modules: card stack parts, card taking and moving part, and card reader part. Each module can be independently assembled and positioned on the main body base, allowing layout modifications without redesigning the entire structure while maintaining structural stability through standardized mounting interfaces.
2Ease of manufacture
If card stack parts and card taking and moving part are integrally assembled, then manufacturing simplicity is improved, but modification ease deteriorates
Solution Approach 1:
The patent segments the card issuing unit into independently manufacturable modules that can be assembled through standardized interfaces. This allows each module to be manufactured separately using simpler processes, while the modular assembly enables easy modifications by replacing or repositioning individual modules rather than redesigning the entire unit.
Solution Approach 2:
The patent designs universal mounting interfaces and standardized connection mechanisms that allow the same modular components to be used in different configurations. The card stack parts and card taking and moving part can be mounted in various arrangements on the main body base, providing multi-functionality and ease of modification without requiring specialized manufacturing for each configuration.
3Quantity of substance
If number of card stack parts is increased, then card storage capacity is improved, but device complexity increases
Solution Approach 1:
The patent uses identical modular card stack parts that can be independently added to increase storage capacity. Each module is self-contained with standardized interfaces, so increasing the number of card stack parts from one to multiple does not proportionally increase overall system complexity, as the same standardized components and mounting procedures are reused.

AI summary
A card processing unit may include a card processing part for performing predetermined processing to a card, a card stack part in which a plurality of cards are stacked and stored, and a card feeding part for carrying a card between the card processing part and the card stack part. The card stack part may be structured such that the card stack part is capable of being separated from the card feeding part as a module and mounted on a main body base as a module. A plurality of card stack parts and a plurality of card processing parts may be mounted on the main body base as modules.
