Solution Overview

Problem

Existing smart door locks generate loud noises during unlocking and locking operations, which is particularly disruptive in quiet environments.

Innovation Solution

The smart door lock can be set to operate in a first mode with a slow rotation speed for quiet operation or a second mode with a fast rotation speed for normal operation, based on scenario requirements or manual rotation information, to reduce noise during unlocking and locking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the control component rotates at a fast speed to perform unlocking or locking quickly, then the productivity is improved, but the noise generated increases

Engineering Contradiction:
Improveunlocking or locking speedVSAvoidnoise
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies dynamics by making the rotation speed of the control component variable rather than fixed. The system dynamically adjusts the rotation speed between a first rotation speed (lower speed for reduced noise) and a second rotation speed (higher speed for faster operation) based on the operational state and requirements, thereby resolving the contradiction between productivity and noise generation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the rotation speed parameter of the control component based on different operational modes. By switching between a first rotation speed parameter (for quiet operation) and a second rotation speed parameter (for fast operation), the system adapts to different scenarios and resolves the contradiction between speed and noise

Inventive Principle:
Principle #35Parameter changes

2Object-generated harmful factors

If the control component rotates at a slow speed to reduce noise, then the noise is reduced, but the unlocking or locking operation becomes slower

Engineering Contradiction:
ImprovenoiseVSAvoidunlocking or locking speed
Core Design Contradiction:
Object-generated harmful factorsVSProductivity

Solution Approach 1:

The system dynamically selects the appropriate rotation speed based on real-time conditions. When low noise is required, the first rotation speed is used; when fast operation is needed, the second rotation speed is used. This dynamic adaptation resolves the contradiction between noise reduction and operational speed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotation speed parameter is changed based on operational requirements. The system switches between a first rotation speed parameter (for noise reduction) and a second rotation speed parameter (for improved productivity), allowing flexible adjustment to resolve the contradiction

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided are a lock control method, a lock and a storage medium, relating to the technical field of Internet of Things technologies. In the lock control method, in response to detecting triggering of a target action on the lock, a current control mode of the lock is determined. In response to the current control mode being a first mode, a control component of the lock is controlled to perform the target action at a first rotation speed. In response to the current control mode being a second mode, the control component is controlled to perform the target action at a second rotation speed. The first rotation speed is lower than the second rotation speed.
