Digital Photo Frame Local Code Pairing for Secure WLAN Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional photo frames cannot efficiently display numerous digital photos and videos, consume device storage, require manual operation for management, increase server response time, rely on internet for transmission, and lack secure connections.
Innovation Solution
A digital photo frame system with a server that generates a unique code for secure direct connections with terminals, allowing direct photo/video sharing without internet reliance, and enabling remote management and secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the digital photo frame requests a server to generate a connection code, then the connection can be established securely, but the responding time increases due to transmissions and server calculation burden
Solution Approach 1:
The terminal device generates the connection code locally before establishing connection with the digital photo frame, eliminating the need for server-side code generation and transmission. This preliminary action at the terminal reduces server calculation burden and network transmission time while maintaining secure connection establishment through local code verification.
2Ease of operation
If the server relies on the internet to transmit requests and photos, then centralized control is achieved, but transmission speed decreases and service interruption occurs when disconnected
Solution Approach 1:
The system segments transmission paths into two modes: internet-based transmission for centralized control operations (code generation, account management) and direct local area network transmission for photo/video sharing. This segmentation allows high-speed direct transmission when devices are in the same network environment while preserving centralized control capabilities through internet-based server operations when needed.
3Ease of operation
If photos and videos are saved in the owner's electronic devices for display, then the digital photo frame can display them, but storage space is consumed
Solution Approach 1:
The digital photo frame serves as an intermediary device with its own storage capacity, receiving photos and videos directly from terminal devices via local area network transmission. This intermediary approach allows the owner's electronic devices to maintain photos and videos without being consumed by the owner's personal storage space, as the digital photo frame independently stores and displays the media content.

AI summary
The present disclosure provides a method for generating a code by a digital photo frame. The method including receiving, from the terminal and by a controller of the digital photo frame, a request for connecting the terminal to the digital photo frame; and generating, by the controller of the digital photo frame, a code according to authorization information of the digital photo frame, wherein a server issuing the authorization information of the digital photo frame does not generate the code. The present disclosure also provides a method for transmitting photos or videos between a terminal and a digital photo frame, the method comprising: receiving a request for transmitting the photos or the videos; determining whether the digital photo frame and the terminal use a same WLAN; and instructing the terminal or the digital photo frame to transmit the photos or the videos via the WLAN.
