Parcel Box Door With Recessed Electronic Locking Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receiving and storage devices, such as parcel boxes, face challenges with mechanical locking devices that protrude and pose injury risks, are easily manipulated, and lack necessary security features, especially when used in groups, requiring multiple keys for delivery personnel and lacking in flat surface design for easy operation and security.
Innovation Solution
The design incorporates a recessed area behind the door's front surface forming a finger or hand attachment, eliminating protruding components, and integrates an electronic locking system controlled via a keyboard or screen, with a mechanical lock as a backup, ensuring secure and ergonomic operation without external handles, and using a combination of metal and plastic for stability and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical locking device with protruding handle is used, then the device can be operated easily, but it poses injury risks and is easily manipulated or damaged
Solution Approach 1:
The patent removes the protruding handle from the door surface, extracting the harmful element while preserving the locking function through an electronic locking device that operates without external mechanical handles
Solution Approach 2:
The patent replaces the mechanical locking system with protruding handle and key cylinder with an electronic locking device that can be controlled via code input, transponder, or smart device, eliminating the need for physical handles
2Reliability
If a mechanical locking device with key cylinder is used, then the device provides basic security, but it requires multiple keys for multiple parcel boxes and lacks future security features
Solution Approach 1:
The electronic locking device serves multiple functions: it can be operated via code input on keyboard, through transponder recognition, or via smart device wireless coupling, making it universally applicable across multiple parcel boxes without requiring separate keys
Solution Approach 2:
The patent replaces the mechanical key cylinder system with an electronic locking device that uses electronic authentication methods, providing enhanced security features and the ability to manage access across multiple devices through a unified system
3Reliability
If the surface is made completely flat without protruding components, then security and flat surface design are improved, but operation becomes less intuitive
Solution Approach 1:
The patent moves the operating interface from the external surface to a recessed area on the inner side of the door, creating a new dimensional space for operation that maintains the flat external surface while providing intuitive access points for users
