Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If paper sign-bills are used for logistics delivery confirmation, then the delivery process can be completed, but the sign-bills are easy to be lost and damaged, resulting in low reliability

Engineering Contradiction:

Improvesign-bill return reliabilityVSAvoidloss and damage of paper documents

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces physical paper sign-bills with electronic copies stored on the blockchain. The electronic sign-bill is a digital replica of the traditional paper document, eliminating the physical medium that is prone to loss and damage while maintaining the essential function of delivery confirmation.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical paper-based system with a digital blockchain-based system. Instead of physically handling, mailing, and storing paper sign-bills, the system uses cryptographic hashing and distributed ledger technology to store and verify delivery information, eliminating the vulnerabilities of the mechanical paper system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If paper sign-bills are mailed back to senders, then delivery confirmation can be achieved, but the process is time-consuming and inefficient

Engineering Contradiction:

Improvesign-bill return efficiencyVSAvoidtime for mailing and manual processing

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-storing the sign-bill information and its hash value on the blockchain at the time of delivery. This eliminates the need for subsequent mailing and manual processing, as the information is already available for immediate verification and retrieval by the sender.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical mailing process with instantaneous digital transmission. The sign-bill information is uploaded to the blockchain network in real-time, allowing senders to retrieve confirmed delivery status immediately without waiting for physical mail delivery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple logistics systems are used for sign-bill management, then various logistics functions can be performed, but data synchronization issues arise across systems

Engineering Contradiction:

Improvelogistics system functionalityVSAvoiddata synchronization issues

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates a universal blockchain-based platform that can serve multiple logistics systems simultaneously. The blockchain acts as a common data layer that different logistics systems can access and interact with, enabling various logistics functions while ensuring consistent data synchronization across all connected systems through the shared ledger.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Measurement precision

If manual verification of sign-bills is performed, then accuracy can be checked, but the process is labor-intensive and error-prone

Engineering Contradiction:

Improveverification accuracyVSAvoidmanual intervention requirements

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements self-service verification through cryptographic hash functions. The blockchain automatically verifies the integrity of sign-bill information by comparing hash values, eliminating the need for manual human verification. The system performs its own validation, ensuring accuracy while reducing labor requirements.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual human verification with automated cryptographic verification. Instead of personnel manually checking sign-bill authenticity, the system uses hash value comparison and blockchain consensus mechanisms to automatically verify data integrity, reducing errors and labor intensity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method and apparatus for sign-bill return based on a blockchain, a device and a readable storage medium, through acquiring (SI01) a sign-bill return request sent by a shipment terminal; acquiring (SI02) pre-stored target sign-bill information according to the sign-bill return request; acquiring (SI03) a target hash value corresponding to the target sign-bill information from the blockchain; and sending (SI04) the target sign-bill information to the shipment terminal, when verifying that the target sign-bill information is correct by the target hash value, the tamper-proof blockchain storage of the target sign-bill information is achieved, which not only improves efficiency of the sign-bill return, but also improves reliability of the sign-bill return.
