Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stand-alone sensing system is used, then the system structure is simple, but the sensing performance is low
Solution Approach 1:
The patent combines the sensing system with the transportation device control system into an integrated system. The sensing unit detects object information while the arithmetic operation unit processes this data together with transportation device data (position, speed, operation state) to generate control commands. This merging improves sensing performance by enabling collaborative processing while managing complexity through integrated architecture.
Solution Approach 2:
The arithmetic operation unit serves multiple functions: it processes sensing data from the sensing unit, integrates transportation device data from various sensors, performs arithmetic operations to calculate object information, and generates control commands for the transportation device. This multi-functionality improves sensing performance by enabling comprehensive data processing while avoiding the need for separate dedicated systems.
2Measurement precision
If only visible light sensing is used, then the system is simple, but the detection accuracy is insufficient
Solution Approach 1:
The sensing unit combines visible light sensing and infrared sensing into a single integrated configuration. Both sensing elements detect different physical targets (visible light and infrared radiation) from the same object, providing complementary information that improves detection accuracy while sharing common structural components.
Solution Approach 2:
The sensing unit is segmented into multiple sensing elements that detect different physical targets. The visible light sensor and infrared sensor are separated into distinct elements within the sensing unit, each optimized for its specific wavelength range, allowing independent optimization while achieving comprehensive detection through combination.
3Measurement precision
If multiple physical targets are sensed simultaneously, then the object signal accuracy is improved, but the calculation complexity increases
Solution Approach 1:
The arithmetic operation unit is designed to handle multiple types of input data (visible light signal, infrared signal, transportation device data) and perform various arithmetic operations (addition, subtraction, multiplication, division, comparison) to calculate different object information parameters. This universal processing capability improves object signal accuracy by enabling comprehensive data integration while managing calculation complexity through unified processing architecture.
