Tamper-Resistant Delivery Pouch With Single-Lock Building Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current delivery systems lack secure and tamper-resistant solutions for drop-off and pick-up of packages, requiring someone to be present during delivery and not allowing for easy tracking or secure storage of valuables outside a building.
Innovation Solution
A secure drop-off bag with a tamper-resistant pouch, a locking cable that seals and secures the pouch to a building structure, and a mounting bracket that allows for single-lock operation, combined with RFID tags for tracking, enabling secure delivery and pick-up without needing someone to be present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a secure drop-off bag is left outside a building to receive deliveries, then a person does not need to be home waiting for delivery, but the bag may be tampered with or stolen
Solution Approach 1:
The system divides the security function into multiple components: a tamper-resistant pouch for containing valuables, a separate locking cable for securing the pouch, and a mounting bracket for attachment to the building structure. This segmentation allows each component to be optimized for its specific function while working together to provide comprehensive security.
Solution Approach 2:
The pouch is constructed using composite materials including a tamper-resistant pouch body, a cable lattice structure for reinforcement, and a combination of locking mechanisms. This composite structure provides superior tamper resistance compared to a single-material construction.
2Reliability
If a locking cable is used to secure the pouch to the building structure, then the pouch is tamper-resistant, but the pouch cannot be easily opened and closed by both deliverers and recipients
Solution Approach 1:
The closure system is segmented into a closure mechanism with locking clasp and grommet holes that can be opened and closed repeatedly, while the locking cable with combination lock provides secure sealing. This allows the pouch to be easily opened for delivery/retrieval while maintaining tamper resistance when locked.
Solution Approach 2:
The pouch is pre-equipped with a closure mechanism that includes a locking clasp and grommet holes, allowing it to be quickly opened and closed by both deliverers and recipients without requiring complex tools or procedures.
3Device complexity
If a combination lock is used on the locking cable, then only one lock is needed to both seal the pouch and secure it to the structure, but the lock must perform multiple functions increasing its complexity
Solution Approach 1:
The combination lock on the locking cable is designed to perform multiple functions: it seals the pouch by locking the cable through the closure mechanism, and simultaneously secures the pouch to the building structure by locking the cable to the mounting bracket. This multi-functionality reduces the total number of locks needed.
4Reliability
If a cable lattice is added to the pouch to make it tamper-resistant, then the pouch becomes difficult to tear open, but the pouch structure becomes more complex
Solution Approach 1:
The pouch incorporates a cable lattice structure as a composite reinforcement within or on the pouch body. This cable lattice provides superior tear and cut resistance while maintaining a relatively simple overall pouch structure that is easy to manufacture.

AI summary
A secure delivery apparatus, having: (a) a tamper-resistant pouch; (b) a closure mechanism disposed on the tamper-resistant pouch; (c) a locking cable that passes through the closure mechanism, thereby sealing shut the tamper-resistant pouch; and (d) a mounting bracket attachable to a fixed building structure such as a door or wall, wherein the locking cable connects the tamper-resistant pouch to the mounting bracket, thereby securing the tamper-resistant pouch to the fixed building structure.
