Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional chip-based instruments store sensitive information locally, then data accessibility is improved, but security vulnerability increases

Engineering Contradiction:
Improvedata accessibilityVSAvoidsecurity vulnerability
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts sensitive data storage from the chip-based instrument by using EEPRAM that is erased after each transaction. The chip no longer stores user or instrument information locally, instead relying on temporary EEPRAM storage that is deleted after use, thereby removing the harmful factor of persistent local storage while maintaining data accessibility during transactions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies dynamic storage by using EEPRAM that changes its state from populated to erased after each transaction. The storage capacity is dynamically adjusted based on transaction needs, and the data is temporarily stored then removed, transforming the static storage vulnerability into a dynamic secure storage mechanism.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If EEPRAM is used to minimize local storage, then security is improved, but device complexity increases

Engineering Contradiction:
Improvesecurity vulnerabilityVSAvoidchip functionality
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent makes the chip multi-functional by integrating EEPRAM storage, cryptographic hash key generation, transaction verification, and data erasure capabilities into a single chip. This universal chip design handles multiple functions (storage, security, verification, erasure) that were previously separate systems, thereby managing complexity through integration while achieving enhanced security.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The chip performs self-service by automatically erasing its own EEPRAM content after each transaction without external intervention. The chip verifies transactions, stores data temporarily, and then erases itself, reducing the need for external security management systems and simplifying the overall system architecture despite the advanced functionality integrated into the chip.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If data is temporarily stored in EEPRAM and then deleted, then data security is improved, but processing time increases

Engineering Contradiction:
Improvedata securityVSAvoidtransaction processing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring the EEPRAM storage capacity and erasure protocols before transactions occur. The chip is pre-programmed with cryptographic hash keys and erasure instructions, so when transactions happen, data can be stored and erased immediately without lengthy setup procedures, minimizing processing time while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent rushes through the storage and erasure process by using fast EEPRAM technology that can quickly store and delete data. The transaction process skips unnecessary intermediate steps by directly storing encrypted data in EEPRAM, verifying through cryptographic hashes, and then immediately erasing, thereby reducing processing time while ensuring data security throughout the abbreviated process.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

Systems, computer program products, and methods are described herein for a secure transactional process utilizing a novel approach to data management within resource instruments. The described technology specifically addresses the need for enhanced security in electronic transactions by incorporating a system that dynamically retrieves, encrypts, stores, and subsequently erases transactional data in a secure manner. At the core of these systems is the use of electrically erasable programmable read-only memory (EEPRAM) which temporarily houses transaction details in an encrypted form. The details are securely fetched from an entity server following the verification of a transaction terminal integrity through unique cryptographic keys.
