Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional optical reading devices use a single light detector and imaging unit, then the device structure is simple, but the data transmission capacity is limited
Solution Approach 1:
The patent divides the light receiving function into multiple light detectors (at least three) arranged in specific spatial positions. Each detector captures light information from different angles, enabling the system to receive and process higher capacity data through spatial segmentation of the detection function.
Solution Approach 2:
The patent transitions from a single-point detection approach to a multi-dimensional detection system by arranging light detectors in three-dimensional space with specific intervals and orientations. This spatial dimensionality enhancement allows the system to capture more information dimensions simultaneously, increasing data transmission capacity.
2Measurement precision
If conventional optical reading devices read information symbols on metal surfaces, then the reading process is fast, but mirror reflection causes inaccurate data retrieval
Solution Approach 1:
The patent segments the light detection function into multiple detectors positioned at different spatial locations and angles. This segmentation allows the system to capture light information from multiple perspectives, preventing mirror reflection from completely obscuring the data and enabling accurate retrieval even from metal surfaces.
Solution Approach 2:
The patent introduces multiple light detectors as intermediaries between the light source and the data processing unit. These detectors are strategically positioned to intercept light information before it undergoes complete mirror reflection, acting as mediators that capture the required data while mitigating the harmful effects of reflection.
3Quantity of substance
If information symbols are printed on paper, then the information can be stored, but the data capacity remains limited and cannot be modified
Solution Approach 1:
The patent implements a dynamic data transmission system using visible light communication where data can be transmitted, modified, and corrected in real-time. Unlike static printed symbols, the light-based transmission allows for dynamic changes in data content, enabling adaptation and correction during the communication process.
Solution Approach 2:
The patent utilizes parameter changes in light properties (intensity, frequency, modulation) to encode and transmit data. This allows for higher data capacity compared to fixed printed symbols and enables real-time modification of transmitted information by changing light parameters without requiring physical repositioning or repositioning of the information carrier.
