Method and apparatus for secure delivery of take-out food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tamper-evidence bags for food delivery do not effectively prevent tampering during transit, as they do not provide sufficient security to ensure the integrity of the food packaging.
Innovation Solution
A secure food delivery bag equipped with an electromechanical lock that uses QR code or pin code access control, where the lock is set with a unique code for each use, ensuring that only the intended recipient can open the bag, thereby deterring tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tamper-evidence bags are used to indicate evidence of tampering, then consumer reassurance is improved, but the ability to actually prevent tampering deteriorates
Solution Approach 1:
The patent replaces traditional mechanical tamper-evidence mechanisms with an electromechanical lock system that uses electronic codes (QR code or pin code) for access control. This substitution provides active prevention rather than passive evidence, as the electronic lock can actively deny access to unauthorized persons while still providing clear indication when opened by the authorized recipient.
2Object-affected harmful factors
If a secure electromechanical lock with access control is implemented, then tampering prevention is improved, but device complexity deteriorates
Solution Approach 1:
The patent extracts the access control functionality into a separate, standardized electromechanical lock module that can be integrated into the food delivery bag. This modular approach manages complexity by isolating the complex electronic components into a self-contained unit with defined interfaces, making the overall system more manageable while maintaining strong security capabilities.
Solution Approach 2:
The electromechanical lock is designed to support multiple access methods (QR code scanning and pin code entry) through a single device interface. This multi-functionality reduces overall system complexity by consolidating different access control approaches into one unified mechanism rather than requiring separate systems for each method.

AI summary
A secure food delivery bag with a single point for securing closure with a lock having an associated QR code or pin code enabled access control. The QR code or pin code is uniquely set for each use of the bag and is provided to the intended recipient of the food at the time the food is placed and locked in the bag. The recipient uses the unique QR code or pin code to access the bag contents upon receipt of the bag.
