Delivery Robot Drawer Locking for Selective Multi-Customer Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery robots face challenges in efficiently delivering multiple objects to multiple customers while ensuring secure and selective access to individual drawers.
Innovation Solution
A delivery robot equipped with a moving body, an upper body containing vertically stacked drawers, a drawer locking device with locking protrusions and a locking plate, and a processor for controlling the locking mechanism, allowing selective unlocking of drawers based on input codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple drawers are provided to deliver objects to multiple customers, then delivery capacity is improved, but security and selective access control become more difficult to implement
Solution Approach 1:
The delivery robot divides its storage into multiple independent drawers, each capable of being locked or unlocked independently. The locking plate is segmented into multiple locking portions, each corresponding to a specific drawer, allowing selective access control for each drawer while maintaining security for others.
Solution Approach 2:
A locking plate acts as an intermediary mechanism between the control system and the drawers. This locking plate with multiple locking portions selectively engages with locking protrusions on different drawers, providing a unified interface for secure and selective access control across multiple drawers.
2Reliability
If a locking mechanism is added to secure drawers, then security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism merges multiple locking functions into a single integrated locking plate that can control multiple drawers simultaneously. This unified approach reduces overall system complexity compared to having separate locking mechanisms for each drawer, while still providing individual access control.
Solution Approach 2:
The locking plate serves multiple functions: it can lock or unlock any individual drawer, lock all drawers simultaneously, or remain retracted to allow all drawers to be accessed. This multi-functionality reduces the need for separate control mechanisms for each drawer.
3Measurement precision
If selective unlocking of individual drawers is implemented, then access control precision is improved, but mechanism complexity increases
Solution Approach 1:
Each locking portion on the locking plate is designed with specific local characteristics, including uniquely positioned selection openings at different distances from the bottom end. This local differentiation allows the system to precisely control access to specific drawers while using a single unified locking mechanism.
Solution Approach 2:
The locking portions are arranged in the vertical dimension with different distances from the bottom end of the locking plate. This vertical arrangement creates distinct engagement positions for each drawer, enabling precise selective unlocking through a single linear movement of the locking plate.

AI summary
A delivery robot includes a moving body; an upper body on an upper surface of the moving body; a plurality of drawers vertically stacked at one side of the upper body; a drawer locking device configured to collectively lock each of the plurality of drawers and selectively unlock any one drawer of the plurality of drawers while keeping locked other drawers of the plurality of drawers; and a processor configured to control the moving body and the drawer locking device.
