Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are included in the stylus to detect various operating environment parameters, then the amount of sensor data that can be transmitted to the computing device increases, but the device complexity and data processing overhead increase
Solution Approach 1:
The patent segments the data processing function by introducing a dedicated sensor controller that separates sensor data acquisition and processing from the main computing device. The sensor controller is divided into multiple modules including a sensor interface module for receiving raw sensor data, a data processing module for filtering and processing the data, and an output module for transmitting processed data to the computing device. This segmentation allows the stylus to maintain multiple sensors while reducing the data processing burden on the computing device.
2Adaptability or versatility
If multiple sensors are included in the stylus to detect various operating environment parameters, then the adaptability and versatility of the stylus improve, but the amount of data to be transmitted and processed increases
Solution Approach 1:
The patent extracts and processes only the essential and relevant sensor data before transmission to the computing device. The data processing module selectively filters sensor data based on predefined criteria and gesture recognition algorithms, extracting only meaningful information such as validated gesture events and relevant environmental parameters. This extraction approach maintains the versatility of multiple sensors while significantly reducing the volume of data transmitted to the computing device.
3Measurement precision
If the stylus processes and transmits detailed sensor data to the computing device, then the measurement precision and input accuracy improve, but the data transmission time and processing overhead increase
Solution Approach 1:
The patent performs preliminary processing of sensor data within the stylus before transmission to the computing device. The data processing module pre-filters, validates, and consolidates sensor data in real-time, preparing it in advance for efficient transmission. By performing these actions preliminarily within the stylus, the system maintains high measurement precision through thorough data validation while reducing transmission time by sending only processed and essential data rather than raw sensor streams.
