Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart locks require active user cooperation for identity verification through methods like face recognition or fingerprint scanning, increasing the time and complexity of the unlocking process, leading to a poor user experience.
Innovation Solution
A control method and device for smart locks that detect a target signal from a user's electronic device, parse identification information, obtain images for verification, and determine if the user is the authorized target based on similarity thresholds and unlocking actions, allowing seamless unlocking without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active user cooperation is required for identity verification (face recognition, fingerprint scanning), then security is improved, but the unlocking time and operation complexity increase
Solution Approach 1:
The system performs preliminary actions by detecting the user's electronic device signal and pre-verifying identification information before the user actively initiates unlocking. The door lock proactively obtains images, extracts features, and compares them against stored data in advance, so that when the user approaches, verification is already complete or near-complete, significantly reducing actual unlocking time while maintaining security
Solution Approach 2:
The door lock system performs self-service by automatically detecting the user's presence through electronic device signals, autonomously obtaining images, extracting features, and completing verification without requiring active user cooperation. The system serves itself by initiating and completing the entire verification process automatically, eliminating the need for users to manually trigger recognition functions
2Measurement precision
If active user cooperation is required for identity verification, then verification accuracy is maintained, but operation complexity increases
Solution Approach 1:
The system implements self-service by automatically detecting electronic device signals, obtaining images, extracting features, and completing verification without any manual user input. The door lock autonomously manages the entire verification process, from signal detection to final unlocking decision, eliminating complex user operations while maintaining verification accuracy through automated feature extraction and comparison algorithms
3Reliability
If multiple verification steps (identification information, images, actions) are implemented, then security is enhanced, but device complexity increases
Solution Approach 1:
The system merges multiple verification functions into an integrated automated process. The electronic device signal detection, image acquisition, feature extraction, and verification are combined into a single seamless workflow that the door lock executes automatically. By merging these functions into one unified process, the system enhances security through multiple verification layers while avoiding the complexity burden that would result from separate manual verification steps

AI summary
The present invention relates to a control method, device, and storage medium for an intelligent door lock. The method comprises: detecting, by a computing device, a target signal associated with an unlocking object; parsing the identification information of the unlocking object from the target signal; based on determining that the identification information is the target identification information, obtaining a first image of the unlocking object; determining whether the unlocking object is a target object based on the first image; and based on determining that the unlocking object is determined to be the target object and detection of an unlocking action, controlling the intelligent door lock to unlock.
