Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current 5G icon display methods on electronic devices often show a 5G connection when the device is actually using LTE networks, leading to user disappointment due to inconsistent performance, causing a fraudulent signal perception and impacting product quality and brand reputation.

Innovation Solution

An icon display method that detects the actual network connection by sending an attach request to a 5G network cell and determining the connection result, ensuring the 5G icon is only displayed when a successful 5G connection is established, and displaying it as 4G if not, thereby preventing the display of 'fake 5G signals'.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device displays a 5G icon when connected to a 4G network, then the device appears to have 5G capability and coverage, but the user experiences inconsistent performance and fraudulent signal perception

Engineering Contradiction:

Improve5G capability displayVSAvoidsignal authenticity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs a preliminary attach request to the 5G network cell before displaying the 5G icon. This preliminary action verifies actual 5G connectivity capability, ensuring that the icon is only shown when genuine 5G connection is possible, thus preventing fraudulent signal display while maintaining 5G capability adaptability

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the electronic device performs an attach request to verify 5G connection, then the signal authenticity is improved, but the connection establishment time increases

Engineering Contradiction:

Improveconnection verification accuracyVSAvoidnetwork connection establishment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs only a partial attach request (sending the attach request and receiving connection result) without completing full network registration. This partial action provides sufficient verification for icon display purposes while minimizing the time penalty compared to a complete network attachment process

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If the electronic device sends an attach request to a 5G network cell, then the icon display accuracy is improved, but the network signaling overhead increases

Engineering Contradiction:

Improvenetwork status detection accuracyVSAvoidnetwork signaling messages

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The system extracts only the essential signaling components needed for connection verification (attach request and connection result) from the complete network attachment process. This extraction provides sufficient measurement precision for icon display while minimizing signaling overhead by omitting unnecessary registration and configuration messages

Inventive Principle:

Principle #2Taking out (Extraction)
