Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical consent forms are used for personal data authorization, then verification records can be provided, but costs and time consumption become excessively high

Engineering Contradiction:

Improveverification recordVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces physical consent forms with electronic copies stored on a blockchain. The blockchain creates a digital replica of the consent form that maintains verification capabilities while eliminating the need for physical printing, handling, and delivery. The electronic consent form is hashed and stored immutably on the blockchain, providing a verifiable record without time and cost losses associated with physical forms.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical physical consent form system with an electronic blockchain-based system. The mechanical processes of printing, signing, and physically delivering forms are replaced by electronic generation, digital signing, and automated delivery through the blockchain network, significantly reducing time and operational costs.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If physical consent forms are used for personal data authorization, then authorization can be obtained, but costs associated with paper, printing, and delivery become excessively high

Engineering Contradiction:

Improveauthorization processVSAvoidcost

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent uses blockchain to create a digital copy of the consent form that eliminates the need for physical paper, printing resources, and delivery logistics. The blockchain stores a cryptographic hash of the consent form, providing a cost-effective verification mechanism that replaces expensive physical infrastructure.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical physical consent form system with an electronic blockchain-based system, eliminating costs associated with paper production, printing operations, and delivery services while maintaining the authorization functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of time

If electronic consent forms are implemented, then costs and time are reduced, but data tampering and verification reliability become concerns

Engineering Contradiction:

Improveprocessing timeVSAvoiddata integrity

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent applies preliminary cryptographic hashing of the consent form content before storage on the blockchain. This pre-computed hash serves as a digital fingerprint that can be used to verify the integrity of the consent form later, preventing tampering while enabling rapid electronic processing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses blockchain's immutable ledger as a disposable verification record that can be rapidly generated and verified. The blockchain entry serves as a single-use verification mechanism that provides reliable integrity checking without requiring ongoing physical form management.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Reliability

If third-party validation is enabled, then verification records can be provided, but system complexity and infrastructure requirements increase

Engineering Contradiction:

Improvethird-party validationVSAvoidsystem infrastructure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the blockchain serve multiple functions: it stores the consent form hash, provides verification records, enables third-party validation, and maintains data integrity. This multi-functional approach eliminates the need for separate complex validation infrastructure while providing comprehensive third-party verification capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A dynamic consent management platform and a personal information management method thereof are provided. The dynamic consent management platform includes a dynamic consent module, a blockchain and a system database, and the personal information management method includes: the dynamic consent module transmitting an unsigned dynamic consent form to a signer module, wherein the unsigned dynamic consent form is generated according to personal data usage ss; the dynamic consent module receiving the signed dynamic consent form from the signer module, wherein the signed dynamic consent form is generated through an identity verification procedure; the dynamic consent module receiving a confirmation signal from the signer module as authorization to generate a decentralized identity verifiable certificate according to the identity verification procedure and the signed dynamic consent form; the blockchain receiving and recording the decentralized identity verifiable certificate; and the system database storing the signed dynamic consent forms.
