Sensor Data Buffering for Flexible Low-Latency Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sensor systems lack flexibility in data manipulation and output, with limited control over the time interval between data provision and output, leading to inefficiencies in data processing and increased latency.
Innovation Solution
A sensor system with a data processing device, such as a microcontroller, that allows for configurable time intervals between data provision and output, enabling data manipulation, correction, and compression within a predetermined time window, reducing latency and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sensor data are outputted immediately after provision without manipulation time, then latency is reduced, but flexibility in data manipulation is limited
Solution Approach 1:
The system dynamically adjusts the time interval between data provision and output based on manipulation requirements. The control device can configure different time intervals allowing data to remain in the provision device for varying durations, enabling flexible manipulation while managing latency according to specific application needs.
Solution Approach 2:
The provision device acts as an intermediary buffer between the sensor element and output device. This intermediate storage allows data to be held temporarily, enabling manipulation operations while decoupling the timing of data generation and output, thus resolving the conflict between immediate output and manipulation flexibility.
2Productivity
If data manipulation operations are performed within the time interval, then data processing effectiveness is improved, but device complexity increases
Solution Approach 1:
The control device performs multiple functions: it controls the sensor element, manages the provision device, configures time intervals, and orchestrates data manipulation operations. This multi-functionality consolidates complexity into a single control unit rather than requiring separate dedicated components for each function.
Solution Approach 2:
The system uses its own internal resources (provision device, control device) to perform data manipulation operations on the sensor data before output. The data processing is self-contained within the sensor system, eliminating the need for external complex processing equipment.
3Adaptability or versatility
If a configurable time interval is provided between data provision and output, then flexibility is increased, but loss of time increases
Solution Approach 1:
The time interval is made dynamic and configurable rather than fixed. The control device can adjust the interval duration based on manipulation requirements, allowing the system to optimize between flexibility and time loss for different operating conditions and application scenarios.
Solution Approach 2:
Data are prepared and stored in the provision device in advance of output, during the configurable time interval. This preliminary storage and preparation enables manipulation operations to be performed without rushing the process, allowing flexible timing while ensuring data readiness for output when needed.
