Solution Overview

Problem

Existing blockchain-based digital tokens lack flexibility in modifying or adding asset-specific attributes after issuance, leading to compliance issues with standard changes and inability to adapt to new standards.

Innovation Solution

The digital token is designed with a structure containing a header, attribute, and immutable component, allowing modification or addition of asset-specific attributes via key-value pairs post-issuance, enabling compliance with evolving standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the digital token uses a fixed standard with predefined asset-specific attributes at issuance, then the token structure is simple and compliant with the standard, but the user is unable to modify or add asset-specific attributes after issuance

Engineering Contradiction:

Improveability to modify or add asset-specific attributesVSAvoidtoken structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The token is segmented into distinct components: a header component containing standard-required attributes, an attribute component containing modifiable asset-specific attributes stored as key-value pairs, and an immutable component containing fixed attributes. This segmentation allows the attribute component to be modified independently while maintaining compliance with the fixed standard structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attribute component is designed to be dynamic, allowing asset-specific attributes to be added, modified, or removed after token issuance through smart contract functions. This dynamic capability enables adaptation to changing standards or new asset requirements without reissuing the entire token.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the digital token uses a fixed standard with predefined asset-specific attributes, then the token issuance process is straightforward, but the user is unable to keep up with standard changes or adapt to new standards

Engineering Contradiction:

Improvecompliance with evolving standardsVSAvoidtime to adapt to standard changes

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The token structure preliminarily allocates separate mutable and immutable components, preparing the framework for future standard changes. The attribute component is pre-configured as modifiable, so when standards evolve, users can immediately update attributes without structural changes or reissuance delays.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the digital token allows modification of asset-specific attributes after issuance, then the token is flexible and adaptable, but the standard compliance may be compromised

Engineering Contradiction:

Improveflexibility in attribute modificationVSAvoidstandard compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Different parts of the token have different qualities: the header and immutable components maintain fixed, standard-compliant attributes, while the attribute component allows localized modifications. This local quality differentiation enables flexibility in non-critical attributes while preserving standard compliance in critical structured fields.

Inventive Principle:

Principle #3Local quality

AI summary

This disclosure enables a digital token with a set of asset-specific attributes. where the set of asset-specific attributes is modifiable or enabled to receive a new asset-specific attribute at least after the digital token with the set of asset-specific attributes is issued on a blockchain-based tokenization platform. Such functionality may be enabled via the digital token containing an attribute component with a set of key-value pairs populated with a subset of the set of asset-specific attributes. where the set of key-value pairs is programmed to be modified or have a new key-value pair being added thereto after the digital token is issued on the blockchain-based tokenization platform.
