Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current tracking methods are used to track disseminated data in wireless ad-hoc networks, then data dissemination tracking is achieved, but network resources are consumed heavily
Solution Approach 1:
The patent extracts the tracking information (sign data) from separate transmission and embeds it within the data payload itself through encoding. This eliminates the need for separate tracking messages and verification packets, thereby reducing network resource consumption while maintaining tracking capability.
Solution Approach 2:
The patent combines the data payload and tracking information (sign data) into a single encoded message. By merging these functions into one transmission unit, the system avoids redundant network traffic and reduces overall resource consumption while preserving both data delivery and tracking functionalities.
2Measurement precision
If verification data is transmitted separately to track data dissemination, then tracking accuracy is improved, but verification data may be easily destroyed
Solution Approach 1:
By combining verification data with the main data payload through encoding, the system ensures that both are transmitted together and received together. This eliminates the risk of separate verification data being lost or destroyed during transmission, while maintaining tracking accuracy through the integrated verification mechanism.
Solution Approach 2:
The patent incorporates verification data into the encoded payload in advance, creating a resilient structure where verification information is protected within the main data stream. This prior integration cushions against potential loss or destruction of verification data during transmission.
3Quantity of substance
If sign data is encoded into digital data through linear combination operation, then data size remains unchanged, but decoding complexity increases
Solution Approach 1:
The patent uses linear combination operations with carefully selected parameters (encoding coefficients) that enable efficient decoding. By changing the mathematical parameters of the encoding scheme, the system achieves compact representation without excessive decoding complexity, balancing data size efficiency with computational feasibility.
