Solution Overview

Problem

The existing process of switching between application services on electronic devices is cumbersome and negatively impacts user experience, requiring users to navigate through multiple applications and interfaces.

Innovation Solution

An electronic device is designed to recommend associated services by displaying multiple service cards simultaneously in a chat interface, allowing users to switch between services without leaving the chat application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users navigate through multiple applications to access related services, then services can be accessed, but the operation process becomes complicated and user experience deteriorates

Engineering Contradiction:
Improveservice switching processVSAvoidapplication switching procedure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple application services into a unified card display interface within the chat application. Service cards from different applications (video playback, ticket purchasing, projection) are integrated and displayed together, allowing users to access services without switching between applications, thereby simplifying the operation process while maintaining service functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The chat application is enhanced with multi-functionality by incorporating service card display and recommendation capabilities. The same chat interface serves both communication purposes and service access purposes, eliminating the need for separate application switches and improving ease of operation

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

2Productivity

If users perform multiple operations to access related services, then services can be accessed, but time consumption increases

Engineering Contradiction:
Improveservice access efficiencyVSAvoidtime for application switching
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-fetching and displaying service cards from multiple applications before the user actually needs them. When a user views a service card, related service cards are already prepared and displayed in the same interface, eliminating the need for subsequent application switching and reducing time consumption

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables users to skip the traditional application switching process entirely. By displaying all necessary service cards within the chat interface, users can directly access related services without rushing through multiple application screens, thereby improving service access efficiency and reducing time loss

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

This application provides a service recommendation method and an electronic device, and relates to the terminal field. When displaying a service, the electronic device may recommend, to a user, another service associated with the service, to simplify a jumping procedure between application services, and improve user experience. The method includes: The electronic device displays a chat interface with a first contact in a chat application. The electronic device receives and displays a first message input by a user in the chat interface. The electronic device obtains a first service card corresponding to the first message, where the first service card is provided by a first application. The electronic device obtains a second service card associated with the first service card, where the second service card is provided by a second application. The electronic device displays the first service card and the second service card in the chat interface.
