Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If oral contracts are used for on-the-spot agreements, then convenience and speed of contract formation are improved, but reliability and provability of contract contents deteriorate due to forgery and falsification risks
Solution Approach 1:
The patent creates digital copies of oral contract conversations through audio/video recording and generates corresponding text transcripts. These digital copies are then stored on IPFS and recorded on blockchain, creating an immutable record that proves the contract contents without requiring physical written documents during the signing process.
Solution Approach 2:
The patent replaces traditional mechanical documentation methods (handwriting, typing, physical signatures) with electronic and digital systems. Audio/video recordings are converted to text through speech recognition, and the entire contract process is managed through electronic platforms with automated timestamping and cryptographic verification.
2Reliability
If written contracts are used to prove contract contents, then reliability and provability are improved, but time consumption and documentation costs increase
Solution Approach 1:
The system performs preliminary actions by automatically recording audio/video of the contract conversation and generating text transcripts in real-time during the negotiation process. The timestamp and metadata are captured automatically at the moment of signing, eliminating the need for post-signing documentation efforts.
Solution Approach 2:
The contract system performs self-service by automatically capturing audio/video, generating transcripts, creating digital signatures, and storing records on IPFS and blockchain without requiring manual intervention for documentation. The system autonomously ensures provability through automated cryptographic verification and immutable storage.
3Ease of operation
If traditional storage methods are used for contract records, then ease of access is improved, but security and integrity of contract contents deteriorate due to potential forgery and data manipulation
Solution Approach 1:
The patent segments the contract storage system into multiple independent components: audio/video files stored on IPFS, metadata stored on blockchain, and cryptographic signatures distributed across the network. This segmentation ensures that no single point of failure can compromise the entire contract record, and each component can be accessed independently for verification.
Solution Approach 2:
The system changes the storage parameters from centralized databases to distributed decentralized storage (IPFS) and immutable ledgers (blockchain). The contract data is transformed from editable documents to cryptographic hashes and digital signatures, fundamentally changing how contract integrity is maintained and verified.
Data Source
AI summary
A server for providing a contract support service communicates with a plurality of contractor terminals, the InterPlanetary File System (IPFS) and a blockchain network, and manages member information for the plurality of contractor terminals. The contract support service provision server acquires audio/video contents including audio/video files in which contract-related audio/video data are stored and metadata for audio/video, in response to a request for contract support from one contractor terminal of the plurality of contractor terminals, generates contract document information corresponding to the contract-related audio/video data, generates a provisional contract content including the generated contract document information and audio/video contents, generates first link information adapted to provide access to the generated provisional contract content and second link information adapted to provide connection with a web page to receive electronic signatures of the plurality of contractor terminals as an input, and transmits the generated first link information and second link information to the plurality of contractor terminals included in the request for contract support. In addition, when a plurality of electronic signatures are input for each contracting party from the plurality of contractor terminals that have confirmed the provisional contract content, contract support service provision server generates audio/video watermarks for the contract content including the provisional contract content and the plurality of electronic signatures, adds the generated audio/video watermarks to the provisional contract content to generate a contract content for storage, encrypts the contract content for storage using an encryption key, and stores the encrypted contract content for storage in a distributed manner using the InterPlanetary File System (IPFS) and the blockchain network.
