Credit Card Sized Portable Computer with Reader Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing systems are large, cumbersome, and vulnerable to data theft and corruption, lacking the portability and security needed for modern applications.
Innovation Solution
A portable computing system comprising a hand-held, credit card-sized computer that requires a reader for operation, featuring all components of a fully functional general-purpose computer, including a processor, memory, and biometric scanner, with a secure design that prevents direct user interaction and retains no data on the reader, ensuring security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional computing systems are used, then computing capabilities are sufficient, but portability and ease of carrying are poor
Solution Approach 1:
The computing system is divided into two separate components: a portable computer unit containing processing components and a reader unit containing input/output devices. This segmentation allows the computer to be small and portable while the reader provides full computing functionality when connected.
Solution Approach 2:
The reader is designed to be compatible with multiple different portable computers, providing universal access to computing functions across different devices and applications.
2Reliability
If conventional computing systems are used, then data storage capacity is sufficient, but security against data theft and corruption is poor
Solution Approach 1:
Data and processing components are extracted from the reader and placed exclusively in the portable computer. The reader retains no data after disconnection, which prevents data theft and corruption at the reader location while maintaining full computing functionality during use.
Solution Approach 2:
The portable computer acts as an intermediary between the user and the reader, holding all sensitive data and processing power, while the reader serves only as a temporary interface for input/output operations.
3Length of moving object
If the portable computer is made very small, then portability is improved, but direct user interaction capability deteriorates
Solution Approach 1:
The portable computer provides its own processing and data storage capabilities, while the reader provides the input/output interface. Together they form a complete system that doesn't require external assistance for basic computing operations.

AI summary
A computing system comprising a portable computer and a reader are disclosed. The portable computer is pocket-sized and comprises flash memory, and optionally a processor and a GPS chip. The reader includes a monitor, a keyboard with docking port and an optional processor and at least one input/output USB connector. A user cannot interact with the portable computer without the reader. The reader is a non-functioning “shell” without the portable computer, however, when they are connected the system becomes a fully functional personal computer. To log on, a user provides security information, for example, a password or biometrics, such as fingerprints. The credit card size and capabilities of the portable computer allows a user to easily carry virtually their entire computer in a pocket for use anywhere there is a reader. In addition, the portable computer provides security against unauthorized use, even if lost or stolen.
