Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor resolution and task model complexity are increased to improve task accuracy, then task accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the sensor resolution and task model complexity adjustable rather than fixed. The system dynamically configures these parameters based on the specific task requirements, starting with low settings and incrementally increasing them only until the desired accuracy threshold is met. This resolves the contradiction by allowing the system to adapt its resource consumption to the actual needs of each task.
Solution Approach 2:
The patent changes key parameters (sensor resolution, sampling frequency, task model complexity) to resolve the contradiction. By systematically varying these parameters and evaluating task accuracy at each step, the system identifies the minimum configuration needed to achieve acceptable performance, thereby minimizing energy consumption while maintaining sufficient accuracy.
2Use of energy by moving object
If sensor resolution and task model complexity are decreased to reduce energy consumption, then energy consumption is reduced, but task accuracy deteriorates
Solution Approach 1:
The patent applies partial action by using only the minimum sensor resolution and task model complexity necessary to achieve the required accuracy threshold. Rather than consistently using high-resolution sensors and complex models, the system uses just enough computational resources to meet the task requirements, avoiding excessive energy consumption while preventing accuracy deterioration through systematic evaluation.
Solution Approach 2:
The patent employs simpler, less energy-intensive sensor configurations and task models when sufficient for the task, rather than always using expensive high-performance components. The system selectively uses higher resolution and complexity only when necessary, effectively deploying the lowest-cost configuration that still achieves acceptable performance.
3Use of energy by moving object
If data transmission from sensors is compressed to reduce energy consumption, then energy consumption is reduced, but data quality and task accuracy may deteriorate
Solution Approach 1:
The patent applies preliminary action by configuring sensor resolution and data collection parameters before data transmission occurs. By determining the appropriate sensor settings in advance based on task requirements, the system avoids the need for post-processing compression that could degrade data quality, while still minimizing energy consumption from the outset.

AI summary
Embodiments disclosed herein relate to methods and apparatus for managing a sensor grid system including configuring and using sensor grids for various tasks. In one embodiment there is provided a method of configuring a sensor grid system having a plurality of sensors arranged to collect data from a working space. The method includes applying an output from the sensors to a task model for performing a task associated with the working space. A task accuracy parameter is corresponding to the accuracy with which the task model performs the task is determine.
