Seed Phrase Disk Assembly for Concealed Crypto Key Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cryptographic keys and seed phrases stored on physical media, such as paper, are susceptible to loss or theft, posing a security risk.
Innovation Solution
A seed phrase storage device comprising encoding disks with physical representations of numbers arranged on a holding rod, secured by separator and anchor nuts, ensuring the seed phrase is not visible upon inspection and thus secure against theft or loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If seed phrases are stored on physical media such as paper, then the storage is simple and accessible, but the security is compromised as they are susceptible to loss or theft
Solution Approach 1:
The seed phrase is segmented into multiple individual encoding disks, each representing a portion of the complete seed phrase. This segmentation allows the information to be distributed across multiple components rather than stored on a single vulnerable medium, thereby improving security while maintaining accessibility through the assembly of parts.
Solution Approach 2:
The encoding disks are designed to be nested or stacked together in a compact configuration, similar to nested dolls. This allows the complete seed phrase information to be contained within a small, portable device that can be securely stored while remaining easily accessible when needed.
2Ease of operation
If the seed phrase is made visible or easily readable, then accessibility is improved, but vulnerability to unauthorized access increases
Solution Approach 1:
The seed phrase information is divided and encoded across multiple separate disks rather than being displayed as a continuous readable text. Each disk shows only a fragment or coded representation, making it impossible to reconstruct the complete seed phrase without assembling all disks in the correct sequence, thus preventing unauthorized reading while maintaining legitimate accessibility.
Solution Approach 2:
The encoding disks utilize visual encoding methods where the information is represented through patterns, colors, or symbolic representations rather than direct text. This allows the seed phrase to be readable by the intended user who knows how to interpret the encoding, while appearing as meaningless patterns to potential thieves or unauthorized observers.

AI summary
A seed phrase storage device includes a holding rod and a sequence of encoding disks configured to represent a word in a seed phrase. Each encoding disk comprises an encoding disk hole and a physical representation of a number, where the encoding disk hole enables each encoding disk to slide onto the holding rod. The storage device includes at least one separator nut including a separator nut hole that enables the separator nut to attach to the holding rod. The at least one separator nut separates a first sequence of encoding disks and a second sequence of encoding disks. The storage device includes at least one anchor nut configured to secure the separator nut and the sequence of encoding disks to the holding rod.
