Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable scanners require external connections and accessories, such as personal computers and cables, to manage and store multiple set-up files, which is costly, cumbersome, and inconvenient, especially for users who need to frequently change settings due to geographical location changes.
Innovation Solution
A scanner with internal working and auxiliary memory, driven by a microprocessor and user interface, allowing users to store, access, and manage multiple set-up files without external connections, using modern high-capacity flash memory and software to facilitate easy management of set-up configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If external personal computers and cables are used to manage multiple set-up files, then storage capacity and file management capability are improved, but device complexity and portability are worsened
Solution Approach 1:
The patent combines the personal computer's storage and processing functions with the scanner by integrating a microprocessor and memory system directly into the scanner device. This merging eliminates the need for external PCs and cables, allowing the scanner to independently store and manage multiple set-up files internally.
Solution Approach 2:
The scanner is designed with multi-functionality by incorporating file management capabilities directly into the device. The microprocessor enables the scanner to perform not only its primary scanning function but also to store, retrieve, and manage multiple set-up files, making the device self-sufficient and reducing dependency on external hardware.
2Quantity of substance
If external personal computers are used to store set-up files, then storage capacity is improved, but ease of operation and portability are worsened
Solution Approach 1:
The scanner performs self-service by incorporating its own file management system. The microprocessor and internal memory allow the device to independently store, retrieve, and switch between multiple set-up files without requiring external computer assistance, making the device self-sufficient and easier to operate in the field.
Solution Approach 2:
Multiple set-up files are pre-stored in the scanner's internal memory, allowing users to quickly switch between different scanning configurations without needing to connect to a computer or reprogram settings. This preliminary preparation of multiple configurations enables immediate deployment in different scanning scenarios.
3Reliability
If external cables and computers are required for file management, then reliability of data storage is improved, but ease of manufacture and cost are worsened
Solution Approach 1:
The patent implements an internal copy of the personal computer's file management system within the scanner. By duplicating the essential storage and retrieval functions in a compact form factor using microprocessor and memory chips, the device achieves reliable data storage without requiring external computer hardware, thereby simplifying manufacturing and reducing costs.
