Solution Overview

Problem

Conventional doorbells lack flexibility in communication methods, leading to poor user experience when users are inconveniently positioned to respond to visitors, as they can only communicate through sound, limiting interaction options.

Innovation Solution

A doorbell system that uses a human body sensing device and smart camera to determine visitor identity and location, allowing the doorbell to adjust its prompting mode, such as projecting text or ringing, based on user settings, enabling more versatile and intelligent communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the doorbell uses only sound prompting, then the device complexity is low, but the adaptability is poor when users are inconvenient to respond

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidprompting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The doorbell system dynamically switches between different prompting modes (sound, text projection, wearable device notification) based on real-time detection of user presence and identity recognition results, making the system adaptable to different scenarios rather than using a fixed single mode

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The doorbell integrates multiple prompting functions including sound prompts, text projection via short-focus projection module, and communication with wearable devices, allowing a single device to serve multiple communication needs and user situations

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

2Ease of operation

If the doorbell provides multiple prompting modes, then the user experience is improved, but the energy consumption increases

Engineering Contradiction:
Improveuser experienceVSAvoiddoorbell energy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The doorbell uses periodic human body detection to determine whether to activate prompting modes, and employs short-focus projection that activates only when visitors are in the effective prompting area, reducing continuous energy consumption while maintaining user experience

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The short-focus projection module projects text information locally onto the ground or wall near the doorbell, providing targeted information to visitors in the immediate area without requiring full-system activation, thus reducing overall energy consumption

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the doorbell uses identity recognition to determine prompting mode, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveidentity-based promptingVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The doorbell combines human body detection, identity recognition, and prompting mode selection into an integrated system where the processor coordinates multiple modules (camera, projection module, wearable device communication) to work together, reducing overall system complexity through unified control

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present disclosure relates to doorbell prompting control method, device and storage medium. The doorbell prompting control method is applied to a doorbell, and includes: determining whether a visitor enters a doorbell prompting area; determining a prompting mode of the doorbell when the visitor enters the doorbell prompting area, the prompting mode being preset by a bound user terminal; and controlling the doorbell to make a prompt according to the prompting mode of the doorbell. By the present disclosure, intelligent control of the prompt made by the doorbell is realized, communication between a user and a visitor is more convenient, the intelligent function of the doorbell is enhanced, and thus user experience is enhanced.
