Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not allow for independent modification of sensor data without affecting the sensor or the consuming application, making it difficult to validate applications with diverse data conditions, simulate sensor variations, or forward data to multiple applications with different requirements.
Innovation Solution
A method and system that receive and modify sensor data by rearranging, adding, removing, or altering samples and timestamps, effectively emulating hardware sensors to send modified data to consuming applications without their awareness, allowing for simulation of different sensor conditions or formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor data is directly transmitted from hardware sensor to consuming application, then data transmission is simple and direct, but the data cannot be independently modified to validate applications with diverse data conditions or simulate sensor variations
Solution Approach 1:
The patent introduces an intermediary component that sits between the hardware sensor and the consuming application. This intermediary receives sensor data, modifies it according to various conditions (adding noise, changing sampling rates, altering timestamps), and forwards the modified data to the application. This resolves the contradiction by enabling diverse data validation scenarios without requiring changes to the sensor or application, while keeping the added complexity localized to the intermediary layer.
Solution Approach 2:
The patent segments the data transmission system into distinct functional layers: the hardware sensor layer, the data modification layer (intermediary), and the consuming application layer. This segmentation allows independent modification of data in the intermediary layer without affecting the sensor or application, enabling versatile validation while maintaining clear system boundaries and manageable complexity.
2Adaptability or versatility
If sensor data is modified independently of sensor and application, then comprehensive validation and simulation capabilities are enabled, but additional data processing infrastructure is required
Solution Approach 1:
The patent creates a virtual copy or emulation of the sensor data stream that can be independently modified. Instead of modifying the actual sensor hardware or the application's data processing, the system creates a副本 (copy) of the sensor data in the intermediary layer and applies various transformations to this copy. This enables comprehensive simulation of sensor variations while keeping the infrastructure requirements limited to the software-based intermediary.
3Productivity
If sensor data is forwarded to multiple applications with different requirements, then data utilization efficiency increases, but data routing and management complexity increases
Solution Approach 1:
The patent designs the intermediary component with multi-functional capabilities to handle diverse data requirements from multiple applications. The same intermediary can apply different modification strategies (noise addition, sampling rate changes, timestamp adjustments) to the same sensor data stream based on the specific requirements of each consuming application. This universal approach improves data utilization efficiency while concentrating routing and management complexity in a single multi-functional component rather than requiring separate processing paths for each application.
Data Source
AI summary
From a hardware sensor at a first time, sensor data comprising a first sample and a second sample is received. The sensor data is modified to create new data, wherein a first data point of the new data corresponds to the first sample, a second data point of the new data corresponds to the second sample, and wherein the first data point and the second data point are arranged differently from the first sample and the second sample. The hardware sensor is emulated by sending, to a consumer of hardware sensor data at a second time, the new data instead of the sensor data.
