Solution Overview

Problem

Users face difficulties in operating electronic devices without call functions to perform calls due to the lack of bootstrapping capabilities, leading to an inconvenient user experience.

Innovation Solution

A call service bootstrapping method that switches user interfaces to bootstrapping and dialing interfaces, providing options and reminders to enable and understand the super call function, even when the call function is not initially enabled.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a user dials a call service number to inquire about electricity, water, or gas services, then the user can obtain service information, but the user has to wait for an operator to answer which causes time loss and low efficiency

Engineering Contradiction:
Improveservice inquiry efficiencyVSAvoidwaiting time for operator answer
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements an automated voice response system that allows users to independently inquire about electricity, water, and gas services without operator assistance. The system automatically recognizes user input, retrieves service information from databases, and provides answers, enabling complete self-service operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an automated voice response system as an intermediary between users and service information. This intermediary automatically processes user inquiries, accesses service databases, and delivers information, eliminating the need for direct human operator intervention while maintaining service quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If manual operation is used for call service inquiry, then the system is simple, but the service quality is poor and user experience is not ideal

Engineering Contradiction:
Improveuser experienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual operator operations with an automated voice response system that uses voice recognition, database querying, and automated speech generation. This substitution maintains system simplicity from the user perspective while dramatically improving service quality through consistent, accurate, and immediate responses.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a multi-functional automated system that can handle various types of inquiries (electricity, water, gas services) through a single unified interface. The system provides diverse service information including balance checks, payment methods, outage notifications, and service applications, all through one automated platform.

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

3Productivity

If automated voice response system is implemented, then service efficiency improves, but the system complexity increases

Engineering Contradiction:
Improveservice inquiry efficiencyVSAvoidautomated system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the automated voice response system into distinct functional modules: voice input recognition module, service type identification module, database query module, information retrieval module, and voice output generation module. Each module handles a specific task, making the overall complex system manageable and maintainable through clear separation of concerns.

Inventive Principle:
Principle #1Segmentation

AI summary

This application provides a call service bootstrapping method, an electronic device, and a storage medium. The method includes: detecting, in response to an operation instruction generated when a phone application is enabled, whether a call function is enabled; switching a current user interface to a first bootstrapping interface if the call function is not enabled, the first bootstrapping interface including a first option; switching the first bootstrapping interface to a first dialing interface in response to an operation instruction generated when the first option is triggered; and switching the current user interface to the first dialing interface if the call function is enabled. According to this application, when a user enables the phone application, the user is bootstrapped to enable the call function. In this way, the user can also answer and make calls even if using an electronic device without a call function.
