Door Lock Control for Robot Loading Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a robot loads or unloads an object from an accommodating portion, there is a risk of the object being stolen from other doors that are not being opened, as existing systems do not effectively control the opening and closing of multiple doors to prevent unauthorized access.
Innovation Solution
An opening-closing control device and system that acquires information on which door to open for the robot's task and controls a lock unit to keep other doors closed, using a door opening information acquisition unit and a control unit to manage the opening and closing of doors based on the robot's position and task information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple doors are opened for loading or unloading objects, then the robot can access multiple accommodating portions, but other doors may be opened unintentionally causing objects to be stolen
Solution Approach 1:
The system segments door control by assigning individual lock units to each door, allowing independent control of each door based on the robot's current task and position. This enables selective opening of only the necessary door while keeping other doors locked, resolving the contradiction between efficient multi-door access and security.
Solution Approach 2:
The door opening information acquisition unit continuously monitors the robot's position and task status, providing feedback to the control unit. This feedback mechanism ensures that door lock units are dynamically adjusted based on real-time operational needs, maintaining security while enabling efficient access when required.
2Reliability
If all doors are kept closed for security, then objects are protected from theft, but the robot cannot load or unload objects efficiently
Solution Approach 1:
The system dynamically adjusts the state of door lock units based on the robot's current position and task requirements. When the robot is positioned at a specific door for loading or unloading, the corresponding lock unit is released to allow door opening, while other lock units remain engaged. This dynamic control resolves the contradiction between maintaining security and enabling efficient operations.
3Ease of operation
If a simple door control system is used, then the system is easy to operate, but it cannot prevent unauthorized access from other doors
Solution Approach 1:
The door control system operates autonomously by automatically acquiring door opening information based on the robot's position and task, then controlling the appropriate lock units without requiring manual intervention. This self-service mechanism maintains ease of operation while implementing sophisticated security control through automated decision-making.

AI summary
An opening-closing control device according to an embodiment of the present disclosure is a device that controls opening and closing of a plurality of doors of an accommodating portion when a robot executes a task of loading or unloading an object to and from the accommodating portion. The opening-closing control device includes a door opening information acquisition unit that acquires information indicating a door to be opened in order to execute the task; and a control unit that controls, based the on the information indicating the door to be opened in order to execute the task, a lock unit that is arranged corresponding to each of the plurality of doors and that is configured to restrict a door other than the door to be opened in order to execute the task in a closed state.
