Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection circuit stores and processes all sensor data locally, then measurement precision is improved, but device complexity and memory requirements increase
Solution Approach 1:
The patent extracts the data storage and processing function from the detection circuit and relocates it to the application processor. The detection circuit only performs initial sensor data acquisition and transmits raw data externally, while the application processor handles comprehensive data processing, three-dimensional coordinate calculation, and application execution. This extraction reduces the detection circuit's memory requirements and complexity while maintaining measurement precision through external processing capabilities.
2Speed
If positional coordinates are calculated locally in the input panel module, then processing speed is improved, but adaptability and data utilization for multiple applications are limited
Solution Approach 1:
The patent implements universality by enabling the application processor to handle multiple application types (touch input, hovering detection, gesture recognition) through a unified raw data processing architecture. The detection circuit transmits comprehensive sensor data that can be processed by different applications according to their specific requirements, making the system adaptable to various functions while maintaining efficient processing through the centralized application processor.
3Adaptability or versatility
If three-dimensional information is transmitted to the application processor, then adaptability is improved, but data transmission volume and processing load increase
Solution Approach 1:
The patent applies segmentation by dividing the data processing workflow into two stages: the detection circuit performs initial sensor data acquisition and transmits only essential raw data (capacitance values and electrode identifiers) to the application processor, while the application processor performs subsequent three-dimensional coordinate calculation and application-specific processing. This segmentation reduces the immediate data transmission volume while enabling comprehensive adaptability through external processing of three-dimensional information.
