Railcar Storage Box Access Mechanism for Key Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autorack railcars face significant challenges in protecting vehicle keys and key fobs from theft, leading to vandalism and operational disruptions, as existing security measures are either ineffective or require complex logistics for access.
Innovation Solution
A secure storage box system integrated into the railcar, featuring a lockable storage box with a sliding panel and two-factor authentication, where the storage box is recessed into the railcar floor or attached to the doors, and accessible only when the railcar doors are open, providing secure storage and easy access for authorized personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keys and key fobs are stored inside vehicles on the autorack, then access to keys is convenient for loading and unloading, but theft and vandalism risk increases
Solution Approach 1:
The patent extracts keys and key fobs from the vehicles themselves and places them in a separate, secure storage box mounted on the autorack. This separation removes the harmful factor (theft risk) while preserving the useful function (access to keys). The storage box can be accessed independently of the vehicles, allowing convenient key retrieval without compromising security.
Solution Approach 2:
The storage box acts as an intermediary between the vehicles and the keys. Instead of directly storing keys inside vehicles (creating security risks) or storing them separately in secure locations (reducing accessibility), the storage box provides a middle ground that balances both security and accessibility needs.
2Object-affected harmful factors
If a secure storage system is implemented for keys, then theft prevention improves, but access complexity and operational time increase
Solution Approach 1:
The patent segments the access control system into multiple independent components: the storage box itself, the locking mechanism, and the combination input device. This segmentation allows for a balance between security and accessibility, where the storage box provides robust theft prevention through its secure locking system, while the combination-based access method maintains operational efficiency by allowing quick access without complex procedures.
3Ease of operation
If the storage box is accessible from the outside when railcar doors are closed, then access convenience is improved, but security is compromised
Solution Approach 1:
The patent implements a dynamic access system where the accessibility of the storage box changes based on the state of the railcar doors. When doors are closed, the storage box remains accessible through its own independent opening and locking mechanism, maintaining operational convenience. When doors are opened, the system can transition to a locked state, enhancing security. This dynamic behavior allows the system to adapt to different operational contexts.

AI summary
According to some embodiments, a railcar comprises a railcar door for accessing an interior of the railcar, and a storage box comprising an access opening. The storage box is disposed such that when the railcar door is in a closed position, the railcar door prevents access to the storage box access opening, and when the railcar door is in an open position, the storage box access opening is accessible. In some embodiments the railcar door comprises a double door, and the storage box comprises a first portion coupled to a first door and a second portion coupled to a second door and adjacent to the first portion of the storage box. The first portion of the storage box prevents access to the second portion when the double doors are in a closed position. In some embodiments, the storage box is recessed into the railcar floor beneath the railcar door.
