Font Library Synchronization for Wearable Storage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices and lightweight devices with limited storage and processing capabilities face challenges in supporting multiple languages and message types, leading to increased storage space requirements, maintenance costs, and inefficient data transmission due to full font library storage and conversion of messages to black-and-white bitmap files.
Innovation Solution
A font library synchronization method that allows a first terminal device with strong storage and processing capabilities to generate and synchronize font library data to a second terminal device with limited resources, performing aging and upgrade processes to manage storage space efficiently, reducing the need for full font library storage and optimizing hardware costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If full font library is stored on the second terminal device to support multiple languages and message types, then display capability is improved, but storage space requirement increases
Solution Approach 1:
The font library is segmented into different types (vector fonts and dot matrix fonts) and further divided into language-specific portions. The system stores only the necessary font portions on the second terminal device rather than the complete font library, enabling selective storage based on actual display requirements.
Solution Approach 2:
The first terminal device acts as an intermediary that generates font library data and synchronizes it to the second terminal device. This mediator approach allows the second terminal device to access font capabilities through synchronization rather than storing the complete font library locally.
2Adaptability or versatility
If font library data is synchronized to support multiple languages, then adaptability is improved, but data transmission amount increases
Solution Approach 1:
Instead of synchronizing the complete font library, the system performs partial synchronization by transmitting only the necessary font data portions required for displaying specific messages. This partial action approach reduces data transmission while maintaining language support capabilities.
Solution Approach 2:
The first terminal device performs preliminary generation and processing of font library data before synchronization. Vector fonts are converted to dot matrix fonts and processed in advance, so that only the essential font portions need to be transmitted to the second terminal device, reducing the overall data transmission amount.
3Adaptability or versatility
If messages are converted to black-and-white bitmap files for display, then display compatibility is improved, but processing capability requirement increases
Solution Approach 1:
The first terminal device performs preliminary conversion of vector fonts to dot matrix fonts and processes message display requirements in advance. This preliminary processing reduces the processing burden on the second terminal device during actual message display, as the font data is already prepared in the appropriate format.

AI summary
This application relates to a font library synchronization method and apparatus, and a storage medium. The method is applied to a first terminal device, and the method includes: identifying font library data information of font library data required for displaying a first message, where the first message is a message to be sent to a second terminal device; identifying, based on a font library synchronization record corresponding to the second terminal device, first font library data information of font library data that has not been synchronized to the second terminal device in the font library data information, where the font library synchronization record includes font library data information of font library data that has been synchronized from the first terminal device to the second terminal device; and sending, to the second terminal device, first font library data corresponding to the first font library data information. According to embodiments of this application, the second terminal device can be prevented from carrying a full font library before delivery, and font library storage space on the second terminal device can be saved, thereby reducing related hardware costs, and improving overall product resource planning and competitiveness.
