Robot Compartment Lid Locking for Secure Item Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ground mobile robots used for last-mile deliveries lack an efficient system for securely storing and retrieving items, as existing solutions fail to ensure item safety during navigation and do not facilitate easy access for customers, particularly due to security concerns and the need for manual intervention.
Innovation Solution
A lid opening and locking system for mobile robots that can be manually or automatically operated, using a powered actuator and hinge mechanism for vertical linear movement converted to circular motion, integrated with a lock mechanism to secure the compartment against unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock mechanism is added to secure items during navigation, then item safety is improved, but device complexity increases
Solution Approach 1:
The lock mechanism is integrated with the lid structure itself, combining the closure function and security function into a single unified system. The lock is built into the lid assembly rather than being a separate added component, which reduces overall device complexity while maintaining item safety during navigation.
2Productivity
If an automated lid opening system is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The lid opening system is designed to automatically execute the opening action without requiring manual intervention. The system serves itself by detecting when the robot arrives at the delivery point and autonomously opening the lid, thereby improving operational efficiency while minimizing the need for complex control systems.
3Ease of operation
If the lid can be opened automatically at delivery points, then customer convenience is improved, but security risks increase
Solution Approach 1:
The automated lid opening system is pre-programmed to execute only under specific verified conditions - namely, when the robot has confirmed arrival at the authorized delivery point. This preliminary verification action ensures that automatic opening occurs only when safe and appropriate, balancing customer convenience with security by preventing unauthorized access.
