Portable Data Stack Holder for Secure Cryptocurrency Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of cryptocurrencies and other sensitive data face challenges in securely storing and accessing password-like data due to its length and vulnerability to loss or unauthorized access, as existing methods lack reliable and secure solutions for memorization and protection.
Innovation Solution
A portable data stack holder comprising a series of tiles with indelibly marked characters that can be slid along a core, featuring a locking mechanism and protective casing to prevent unauthorized access and loss, allowing secure storage and retrieval of sensitive data without specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensitive data is recorded for later recall, then accessibility of the data is improved, but the record could be subject to loss, destruction, or unauthorized access
Solution Approach 1:
The sensitive data is segmented into multiple individual character tiles that can be arranged in sequence. Each tile represents a discrete unit of information, allowing the data to be accessed tile-by-tile while maintaining security. The segmentation enables physical control over information disclosure - only the necessary portion can be exposed at any given time by sliding the appropriate tile into view.
2Ease of operation
If the data is stored in a portable format, then ease of transport is improved, but vulnerability to loss or unauthorized access increases
Solution Approach 1:
The character tiles are nested along a central rod in a compact linear arrangement, allowing the entire data set to be stored in a space-efficient manner. The tiles can be slid along the rod to expose individual characters while remaining physically contained within a small footprint, achieving both portability and security through the nested configuration.
3Quantity of substance
If multiple tiles are stacked to form complete data sets, then information capacity is improved, but difficulty in reading individual characters increases
Solution Approach 1:
The tile stack is designed to be dynamic rather than static, with tiles that can be freely slid along the rod. This dynamic configuration allows the user to easily manipulate the stack to expose individual character tiles for reading, while the tiles remain physically connected when needed for security. The system transitions between a compact stacked state for security and an expanded linear state for reading.

AI summary
A data storage device includes a plurality of tiles whose faces are marked with characters. An elongated core is configured to enable slots of the tiles to fit over an openable end of the core to mount the tiles on the core with the marked faces aligned and to slide along the core. The length of the core is sufficient such that tiles of a mounted stack of tiles are slidable away from other tiles of the stack to form a gap that is sufficient to enable reading the character on the tile. A locking element is placeable on the openable end to prevent removal of tiles from the stack, and removable to enable addition of tiles or removal of tiles. A casing is closable over the core and includes a limiting structure to limit sliding of the tiles when the casing is closed.
