Solution Overview

Problem

Traditional photo frames cannot efficiently display a large number of digital photos and videos, consume storage space on the owner's device, and lack remote management capabilities, making it inconvenient for users to manage and control displayed content.

Innovation Solution

A digital photo frame system that includes a server, digital photo frame, and terminals, enabling secure authenticated connections, storage of photos/videos, and remote management through a controller, communication units, and touch screens, allowing users to manage and control content via a network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If photos/videos are saved in the owner's electronic devices for display, then the digital photo frame can display photos/videos from multiple senders, but the storage space of the owner's electronic devices is consumed and time is spent in collecting photos/videos

Engineering Contradiction:
Improveability to display photos/videos from multiple sendersVSAvoidstorage space of electronic devices
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent introduces a server as an intermediary between multiple senders and the owner's electronic device. The server collects and stores photos/videos from multiple senders, then provides them to the digital photo frame for display. This mediator approach allows the frame to access content from multiple sources without consuming the owner's device storage space, as the data flows through the server infrastructure instead of being stored locally on the owner's device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If photos/videos are saved in the owner's electronic devices for display, then the digital photo frame can display photos/videos, but time is spent in collecting photos/videos from multiple senders

Engineering Contradiction:
Improveability to display photos/videos from multiple sendersVSAvoidtime spent in collecting photos/videos
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The server performs preliminary actions by proactively collecting, storing, and organizing photos/videos from multiple senders before they are needed for display. The system establishes connections with multiple senders in advance and pre-loads content onto the server. When the digital photo frame needs to display content, it can immediately retrieve pre-collected photos/videos from the server without the owner needing to manually collect them from multiple sources, thereby eliminating the time-consuming collection process.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the digital photo frame only allows direct operation by the owner, then the device is simple to operate, but the owner cannot remotely control or manage the digital photo frame

Engineering Contradiction:
Improvesimplicity of direct operationVSAvoidremote control capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements multi-functionality in the control system by allowing the digital photo frame to operate in multiple modes: local direct operation by the owner and remote operation through authorized users' devices. The control system is designed to accept commands from both the owner's direct interaction with the frame and from remote devices through network communication. This universal control architecture enables the frame to maintain its simplicity for direct use while gaining the versatility of remote management capabilities, allowing owners to control the frame from anywhere in the world.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Quantity of substance

If the digital photo frame displays a large number of photos/videos, then it meets the user's need to display numerous photos, but traditional photo frames cannot display videos or meet the need for displaying numerous digital photos

Engineering Contradiction:
Improvenumber of photos/videos displayedVSAvoidability to display both photos and videos
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by transitioning from traditional photo frame limitations to digital capabilities. The digital photo frame utilizes digital storage and display technologies that allow it to handle both image and video file formats, unlike traditional frames that could only display physical photographs. The system changes the fundamental parameters of what can be displayed (from physical photos only to digital photos and videos), the quantity that can be stored and displayed (from limited to numerous), and the sources of content (from single local source to multiple remote sources via server).

Inventive Principle:
Principle #35Parameter changes

AI summary

The present disclosure provides a method for sharing photos or videos with a digital photo frame, the method comprising receiving, by a server, an operation command for connecting at least one terminal to the digital photo frame; generating and transmitting, by the server, a code to the digital photo frame in response to the received operation command; determining, by the server, whether a code entered by the at least one terminal is matched with the generated code; connecting, by the server, the at least one terminal to the digital photo frame when determining that the code entered by the at least one terminal is matched with the generated code; and instructing, by the server, the digital photo frame to receive the photos or the videos from the at least one connected terminal.
