Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lock boxes face security and logistic issues such as theft, difficulty in identifying authorized deliveries, delayed or forgotten relocking, overheating of contents, and challenges with removing large packages due to limited access.
Innovation Solution
A smart lock box system with a control application for remote operation, automatic unlocking and locking, temperature regulation, and enhanced access features, including a bar code scanner, motion sensor, camera, and active cooling, allowing for easy handling of large packages without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a lock box has a large opening to accommodate large packages, then the package capacity is improved, but the user cannot easily access the package due to limited hand space between interior walls and package
Solution Approach 1:
The lock box is divided into two functional openings: a large top lid for receiving and accommodating large packages, and a smaller front access panel for retrieving packages. This segmentation allows the box to accept large items while providing a manageable access point for users to remove packages without needing to fit hands between interior walls and the package.
2Device complexity
If a lock box requires manual unlocking and locking by courier, then the device complexity is reduced, but the delivery time increases and relocking may be forgotten
Solution Approach 1:
The lock box incorporates an automatic locking system with sensors that detect when a package has been placed inside. The system automatically unlocks the top lid for the courier, locks it after package insertion is detected, and subsequently unlocks the front access panel for the user. This self-service automation eliminates manual courier intervention for locking, speeds up delivery, and ensures the box is always secured without requiring courier memory or attention.
3Device complexity
If a lock box has basic locking functionality, then the device complexity is low, but security against theft and unauthorized access is insufficient
Solution Approach 1:
The lock box integrates multiple security and access control functions into a single system: barcode scanning for package identification, motion sensing for courier detection, automated locking/unlocking sequences, and differentiated access for courier and user. This multi-functional approach provides robust security against theft and unauthorized access while maintaining manageable system complexity through integrated control.
4Adaptability or versatility
If a lock box is used in warm climates, then the delivery service coverage is improved, but the interior temperature becomes high enough to damage goods
Solution Approach 1:
The lock box includes an automatic temperature monitoring and cooling system. Temperature sensors continuously monitor the interior environment, and when elevated temperatures are detected, the system automatically activates cooling mechanisms. This self-regulating approach allows the lock box to be deployed in warm climates and various geographic locations while protecting temperature-sensitive goods from damage without requiring manual intervention.

AI summary
A lock box system includes a bottom base. A rear section extends upwards from the base. A side wall cover removably abuts against a perimeter of the base and opposing sides of the rear section. The cover is pivotally attached to an upper portion of the rear section. A locking mechanism is operable to lock the cover to the rear section. A top lid is sized to removably fit over the cover. The lid is pivotally attached to the upper portion of the rear section. The base, rear section, cover and lid define an interior of the lock box system, which is sized to receive packages. The lid is operable to pivotally open automatically to receive a package within the interior. The locking mechanism is operable to unlock automatically to enable the cover to pivotally open to allow a user access to the package within interior.
