Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data compression techniques are used to reduce data volume, then data transmission bandwidth is reduced, but computational load increases significantly at both source and destination
Solution Approach 1:
The patent extracts and transmits only the principal components of sensor data that are responsive to continuous queries, rather than compressing all data. This selective extraction reduces data volume while avoiding the computational overhead of traditional compression algorithms at both encoding and decoding stages.
Solution Approach 2:
The patent applies different data handling strategies to different portions of sensor data based on their relevance to continuous queries. Principal components that respond to queries are transmitted with higher fidelity, while non-responsive data is filtered out, creating a quality-based differentiation in data transmission.
2Loss of information
If all sensor data is transmitted and stored, then complete information is available for analysis, but bandwidth and storage resources are overwhelmed
Solution Approach 1:
The system extracts only the principal components of sensor data that are relevant to continuous queries performed by user applications. This extraction mechanism ensures that transmitted data maintains information completeness for query purposes while dramatically reducing bandwidth consumption by filtering out non-responsive data.
Solution Approach 2:
Rather than transmitting all sensor data (excessive action) or losing information (insufficient action), the patent transmits a partial but sufficient set of principal components that adequately respond to continuous queries, achieving the right balance between information completeness and resource conservation.
3Speed
If data transmission rate is increased to improve real-time analysis, then response time is reduced, but network bandwidth consumption increases
Solution Approach 1:
The patent extracts and transmits only principal components of sensor data at optimized rates, rather than transmitting all sensor data at maximum speed. This selective transmission achieves real-time analysis capabilities while consuming significantly less network bandwidth by focusing only on query-responsive data.
4Measurement precision
If high precision data is transmitted to maintain application accuracy, then query result accuracy is improved, but data transmission volume increases
Solution Approach 1:
The patent extracts principal components with precision optimized for continuous query requirements. By identifying and transmitting only those data components that actually respond to and affect query results, the system maintains application accuracy while minimizing transmission volume through selective precision application.
Data Source
AI summary
A computer program product include non-transitory computer readable storage media having program instructions embodied therewith. The program instructions are executable by a processor to receive a continuous query for a user application and receive unfiltered sensor data transmitted over a network from a local compute node that is operatively coupled to a plurality of sensors, wherein the sensor data includes data obtained from the plurality of sensors. The program instructions are further executable by the processor to identify one or more principal components of the sensor data that are responsive to the continuous query, instruct the local compute node to continue transmitting only the sensor data that has been identified as the one or more principal components, and provide the user application with the sensor data that has been identified as the one or more principal components.
