Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile printers are difficult to miniaturize due to size constraints on printing mechanisms and associated components, and they cannot manage intergroup communication effectively when interacting with external devices.
Innovation Solution
A compact, portable printing apparatus equipped with intergroup communication capabilities, featuring a printing part, data receiver, and print controller, allowing for wireless communication with information terminals and other devices using Bluetooth Low Energy, enabling efficient data management and printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional printing mechanisms and associated components are included in a mobile printer, then printing functionality is achieved, but the device size cannot be reduced
Solution Approach 1:
The patent extracts the printing mechanism from the mobile device by implementing a wireless printing system where the mobile terminal communicates print data to a separate printing apparatus via Bluetooth Low Energy intergroup communication, eliminating the need for a built-in printing mechanism in the mobile printer
Solution Approach 2:
The printing apparatus is designed to function both as a standalone printer and as a master device in Bluetooth Low Energy intergroup communication, enabling it to manage communication with multiple slave devices including mobile terminals, thereby achieving multi-functionality
2Adaptability or versatility
If conventional mobile printers prioritize printing function, then printing capability is enhanced, but communication management capability is lost
Solution Approach 1:
The printing apparatus dynamically switches between operating modes: it can function as a slave device when receiving print jobs, or as a master device when managing intergroup communication with multiple slave devices, allowing adaptive role assignment based on communication needs
