Bag Sealing System with Integrated Spool Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag sealing methods for valuables and dangerous items are not tamper-proof and can be easily defeated, necessitating the development of cost-effective, bespoke solutions for secure storage and transportation.
Innovation Solution
A bag sealing system comprising a moveable frame, a closable bag with a securing element, and a closing device actuated by a driving device, which securely closes the bag by moving the frame from an open to a closed configuration, locking the securing element within a rotatable spool housing to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sealing methods are used, then the sealing process is simple, but the security against tampering is insufficient
Solution Approach 1:
The securing element is stored within the closing device itself, with the distal end embedded in the bag neck and the proximal end stored in the closing device. This nesting approach integrates the securing mechanism into the closing device structure, providing tamper-proof security while avoiding the need for separate external locking components.
Solution Approach 2:
The securing element is divided into distinct functional segments: the distal end embedded in the bag neck for anchoring, the intermediate portion for tensioning, and the proximal end stored in the closing device for controlled release. This segmentation allows each part to perform its specific function efficiently while contributing to overall system security.
2Reliability
If a secure closing mechanism is implemented, then tamper resistance improves, but the device complexity increases
Solution Approach 1:
The closing device combines multiple functions into a single integrated structure: it closes the bag opening, stores the securing element proximal end, provides tensioning through the spool mechanism, and enables controlled release. This merging reduces the number of separate components needed while maintaining high tamper resistance through the integrated secure closing mechanism.
3Difficulty of detecting and measuring
If the securing element is stored in the closing device, then tamper detection capability improves, but the manufacturing complexity increases
Solution Approach 1:
The closing device structure provides its own tamper detection capability through the integrated securing element storage. The spool mechanism and housing naturally indicate when the securing element has been removed or tampered with, without requiring additional sensors or detection systems. This self-service approach enhances security while keeping manufacturing relatively simple.

AI summary
A bag sealing system for securing one or more items in a closable bag comprises a moveable frame, a closable bag, a closing device and a driving device. The moveable frame can have an open configuration, intermediate configurations and a closed configuration. The closable bag has an open end and a closed end wherein the open end of the closable bag is coupled to the moveable frame. The closing device is provided for securely closing the open end of the bag via a securing element, and the driving device is coupled to the closing device to actuate the closing device to securely close the closable bag.
