Problem

Existing inter-device linkage technologies fail to integrate advanced functionalities, such as seamless image processing and display across multiple devices, leading to inconvenient user operations due to limited capabilities of individual devices.

Innovation Solution

A system comprising a first and second electronic device, where the first device detects user operations and sends request information to the second device to retrieve image information at a specific moment, enabling enhanced image processing capabilities such as translation, object recognition, and object shopping link viewing across devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing inter-device linkage technologies are used for interface integration and file transfer, then device connectivity is achieved, but user operation convenience deteriorates due to limited single-device capabilities

Engineering Contradiction:
Improvedevice connectivityVSAvoiduser operation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent enables a single device to access and utilize capabilities from multiple different devices through the capability invocation mechanism. The first device can invoke processing capabilities (translation, object recognition, etc.) from a second device, making the system universally adaptable to various processing needs without requiring each device to have all capabilities locally.

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

Solution Approach 2:

The patent introduces a mediator mechanism (the capability invocation system involving the processor and display device) that facilitates interaction between devices with different capabilities. The mediator manages the complex interactions of capability detection, invocation, and result display, simplifying user operations while maintaining device connectivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple devices are used to perform complex tasks, then functional capability is improved, but system complexity increases

Engineering Contradiction:
Improvefunctional capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically detects available capabilities on connected devices and manages the invocation process without requiring user configuration. The processor automatically identifies which capabilities are available on the second device and invokes them appropriately, reducing system complexity while maintaining enhanced functional capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent segments different functional capabilities across multiple devices, with each device specializing in specific functions (e.g., one device for display, another for processing). This segmentation allows complex tasks to be distributed across devices while the system manages the complexity through modular capability invocation rather than monolithic system design.

Inventive Principle:
Principle #1Segmentation

3Productivity

If real-time image processing is performed across devices, then processing speed is improved, but communication overhead increases

Engineering Contradiction:
Improveprocessing speedVSAvoidcommunication overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary capability detection and device pairing before actual image processing occurs. By pre-establishing the capability inventory of connected devices and setting up the invocation framework in advance, the system minimizes communication overhead during real-time processing while maintaining high processing speed through ready-to-use capability pathways.

Inventive Principle:
Principle #10Preliminary action

AI summary

This application provides a method for invoking a capability of another device, an electronic device, and a system. The method includes: A first electronic device is configured to detect a first operation of a user. The first electronic device sends request information to a second electronic device in response to the first operation, where the request information is used to request first image information on the second electronic device. The second electronic device sends the first image information to the second electronic device in response to the request information. The first electronic device processes the first image information by using a first function. Embodiments of this application help improve cross-device use experience of the user.
