Secure containing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Logistics personnel face challenges in ensuring secure delivery and pickup operations without face-to-face contact, as existing solutions lack effective mechanisms for safeguarding items during transportation.
Innovation Solution
A secure containing device with an adjustable volume, featuring a bag covered by an active element that engages with a lock assembly, allowing authorized access while maintaining item security through a combination of connecting-rod assemblies, a lock assembly with identity verification, and a design that compresses for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure containing device is used for logistics delivery without face-to-face contact, then item security is improved, but device complexity increases
Solution Approach 1:
The secure containing device is divided into distinct functional modules: a containing space for items, a seal mechanism with sealing wall and sealing engagement structure, and an identification mechanism with sensor. This segmentation allows each component to perform its specific function independently, achieving reliable item security through coordinated modular operations rather than a monolithic complex system.
Solution Approach 2:
The seal mechanism acts as an intermediary between the containing space and the external environment, providing a physical barrier that prevents unauthorized access. The sealing wall with sealing engagement structure creates an intermediate secure state during delivery, allowing the device to maintain item security without requiring direct human intervention or complex monitoring systems.
2Adaptability or versatility
If the containing device has adjustable volume, then adaptability is improved, but device complexity increases
Solution Approach 1:
The containing device incorporates a dynamic volume adjustment mechanism that allows the containing space to expand or contract based on item volume. This dynamic adaptability enables a single device design to accommodate various sized items without requiring multiple fixed-volume containers or complex modular assembly systems.
Solution Approach 2:
The device changes its geometric parameters (volume, shape) in response to different loading conditions. The containing structure can deform or adjust its dimensions to match the size of inserted items, providing versatile adaptability through continuous parameter adjustment rather than discrete configuration changes.

AI summary
A secure containing device with an adjustable volume for receiving and safeguarding items includes a bag, a rear cover, a mounting element connected to opposite sides of the bag, a lock assembly on the rear cover and protruding toward the mounting element, and an active element overlapping with the mounting element. When the mounting element moves to a closed position, the bag is compressed. When the mounting element moves to an unfolded position away from the rear cover, the bag presents a containing space. When the mounting element is in the unfolded position, the active element is movable and rotatable relative to the mounting element to cover a top of the bag and engage with the lock assembly.
