Solution Overview

Problem

Existing lock control systems lack efficient mechanisms to determine the status and operate the locking mechanism based on real-time conditions, such as obstacle detection and user requests, leading to potential security vulnerabilities and operational inefficiencies.

Innovation Solution

A system comprising a lock, a control device, a storage device, and a processor that moves the locking mechanism between locked and open positions, with integrated status detection and obstacle detection capabilities, allowing the processor to determine the lock's status and adjust its position based on conditions such as obstacle presence, user requests, and operational thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the locking mechanism is actuated to move toward the locked position, then the lock security is improved, but the system cannot detect obstacles in the pathway causing potential damage or malfunction

Engineering Contradiction:
Improvelock securityVSAvoidobstacle damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The obstacle detection device is activated before the locking mechanism is actuated to detect potential obstacles in the pathway. This preliminary detection prevents the locking mechanism from moving if an obstacle is present, avoiding potential damage while maintaining security when the pathway is clear.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The obstacle detection device serves as an intermediary between the control device and the locking mechanism. It provides critical information about the pathway condition, allowing the control device to make informed decisions about whether to actuate the locking mechanism, thus preventing harmful effects while enabling secure locking when safe.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the system continuously monitors lock status and operation information, then the security and control precision are improved, but the device complexity increases

Engineering Contradiction:
Improvelock status detection accuracyVSAvoidsystem component count
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The status detection device and obstacle detection device are integrated into a unified monitoring system controlled by a single control device. This merging of detection functions reduces overall system complexity while maintaining high measurement precision through coordinated operation of multiple sensors under centralized control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control device performs multiple functions: it controls the locking mechanism, processes status information from the status detection device, and manages obstacle detection data. This multi-functionality consolidates control logic, reducing the need for separate control components and simplifying the overall system architecture while maintaining precise monitoring capabilities.

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

3Speed

If the locking mechanism moves quickly to the locked position, then the operation speed is improved, but the system cannot respond to obstacles or abnormal conditions during movement

Engineering Contradiction:
Improvelocking mechanism speedVSAvoidsafe operation
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The obstacle detection device is activated before the locking mechanism begins movement to identify potential hazards in advance. This allows the system to prepare appropriate responses while the locking mechanism operates at high speed, ensuring safety without compromising operational speed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The status detection device continuously monitors the locking mechanism's position and operation status during movement. This real-time feedback enables the control device to detect abnormal conditions and respond appropriately, allowing fast operation while maintaining reliability through continuous monitoring and adaptive control.

Inventive Principle:
Principle #23Feedback

AI summary

A system includes a storage device (150) storing a set of instructions and at least one processor (220, 340) in communication with the storage device (150). When executing the instructions, the processor (220, 340) is configured to cause the system to obtain a request to close a lock (170) such that the lock (170) is in a locked status, and actuate a control device (450) to cause a locking mechanism (910) of the lock (170) to move toward a first position. The processor (220, 340) may also cause the system to determine whether operation information of the lock (170) satisfies a condition relating to an operation of the lock (170), and actuate the control device (450) to cause the locking mechanism (910) to move to the first position or a second position based on a result of the determination as to whether the operation information of the lock (170) satisfies the condition. A method for controlling the system to close the lock (170) and a computer-readable storage medium storing the instructions are provided.
