Smart Call Device Face Recognition for Reliable Connection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional call devices often fail to connect calls when the callee is temporarily absent, as they broadcast sound to inform the callee, interfering with others and leading to unsuccessful connections.

Innovation Solution

A smart call device system that uses a camera and processor to identify faces around the device upon receiving an incoming call signal, sending control signals to either send a text message or voice message based on face recognition, allowing the caller to reach the intended recipient without interrupting others.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional call device broadcasts sound to inform the callee, then the callee can be notified of the incoming call, but it interferes with other people and fails to connect when the callee is temporarily absent

Engineering Contradiction:

Improvecall connection reliabilityVSAvoidsound interference to others

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the acoustic notification mechanism (sound broadcasting) with an optical recognition mechanism (face recognition camera). Instead of using sound waves to notify the callee, the system uses image capture and processing to detect the presence of the callee visually, thereby eliminating sound interference while improving call connection reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a face recognition device as an intermediary between the caller and the callee. This intermediary captures images, processes them to determine callee presence, and then controls whether to forward the call signal, thereby resolving the conflict between notifying the callee and avoiding interference to others

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional call device uses sound broadcasting, then notification is provided, but call connection fails when callee is temporarily absent

Engineering Contradiction:

Improvecall connection success rateVSAvoidmissed call time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs face recognition and presence detection before the call is actually connected. By capturing images and determining callee presence in advance of the call connection decision, the system prevents missed calls due to temporary absence while avoiding unnecessary call attempts that would waste time

Inventive Principle:

Principle #10Preliminary action

AI summary

A smart call method is applied in a smart call device, there being a first handheld device and a second handheld device containing the smart call device. The first and second handheld devices are bound and communicate with the smart call device. The smart call device receives an incoming call signal from the first handheld device and acquires images of nearby faces through an image acquisition unit in response. The first handheld device compares the acquired face images with stored user face images of the second handheld device. The smart call device sends a control signal to the first handheld device according to a successful comparison and the first handheld device calls the second handheld device bound with the smart call device.
