Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized media monitoring system is used, then coordination and control are simplified, but the system becomes prone to disruptions and inefficiencies
Solution Approach 1:
The patent divides the centralized monitoring system into multiple independent nodes distributed across a blockchain network. Each node (media monitoring entity or broadcaster) operates autonomously while contributing to the collective watermark encoding and metadata aggregation process, eliminating the single point of failure inherent in centralized systems.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary layer between media monitoring entities and broadcasters. This decentralized intermediary enables peer-to-peer communication and coordination without requiring a central authority, thereby maintaining ease of operation while improving system reliability through distributed consensus.
2Device complexity
If manual-intensive offline media exposure measurement is used, then system complexity is reduced, but human errors and data duplication increase
Solution Approach 1:
The patent implements automated watermark encoding and metadata aggregation where the system performs measurements and data collection autonomously. Media monitoring entities and broadcasters automatically encode watermarks into media and submit metadata to the blockchain without manual intervention, eliminating human errors while maintaining manageable system complexity through standardized protocols.
Solution Approach 2:
The patent replaces manual mechanical processes with automated digital operations. Instead of manual data collection and watermark encoding, the system uses automated software agents that interact with the blockchain network to perform measurements, encode watermarks, and aggregate metadata, thereby eliminating human errors while keeping the system accessible through standardized interfaces.
3Device complexity
If watermark encoding is performed manually, then device complexity is reduced, but encoding accuracy and consistency deteriorate
Solution Approach 1:
The patent standardizes the watermark encoding process by defining specific parameters and protocols that nodes must follow when encoding watermarks into media. This standardization ensures consistent encoding accuracy across different nodes while maintaining manageable complexity through well-defined technical specifications.
Solution Approach 2:
The patent replaces manual watermark encoding with automated encoding performed by software agents running on each node. This automation ensures consistent and accurate watermark encoding across all media assets while keeping the encoding process accessible through standardized interfaces, thereby improving precision without significantly increasing operational complexity.
4Ease of operation
If centralized metadata aggregation is used, then data collection is simplified, but data security and immutability are compromised
Solution Approach 1:
The patent divides the centralized metadata aggregation function into a distributed network where each node independently contributes metadata to the blockchain. This segmentation ensures data security through decentralization while maintaining simplified data collection through standardized submission protocols that any node can follow.
Solution Approach 2:
The patent uses the blockchain network as an intermediary for metadata aggregation. The blockchain's immutable ledger serves as a secure, decentralized repository that automatically records and preserves metadata from multiple sources, thereby ensuring data security and immutability while maintaining ease of operation through automated submission processes.
