Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether is used to connect the portable digital detector to other components, then power and data transmission are reliable, but the positioning flexibility and ease of operation are reduced
Solution Approach 1:
The patent removes the tether connection from the system by implementing wireless communication capabilities. The portable digital detector includes wireless transceivers that enable power and data transmission without physical cables, thereby eliminating the constraint on positioning flexibility while maintaining transmission reliability
Solution Approach 2:
The mechanical tether connection is replaced with an electromagnetic wireless communication system. The detector incorporates radio frequency transceivers and antennas that substitute the mechanical cable connection, enabling contactless power and data transmission while improving operational ease
2Device complexity
If wireless communication is used without multiple antennas, then device complexity is reduced, but data transmission reliability and throughput are insufficient due to interference
Solution Approach 1:
The wireless communication system is segmented into multiple independent antenna elements. Each antenna can transmit and receive signals independently, allowing the system to divide data streams across multiple channels. This segmentation enables MIMO (Multiple-Input Multiple-Output) communication that improves reliability and throughput without proportionally increasing overall system complexity
Solution Approach 2:
Multiple antenna elements are combined into a unified wireless communication system that works cooperatively. The detector integrates multiple antennas with a shared processing unit that combines signals from all antennas, achieving enhanced data transmission reliability through signal diversity and spatial multiplexing while managing complexity through integrated architecture
3Productivity
If multiple antennas are implemented, then data throughput and interference resistance improve, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The multiple antenna system is designed with universal, standardized components that can be mass-produced using conventional manufacturing techniques. Each antenna element uses identical or similar designs, allowing for modular assembly and simplified production. The same antenna design serves multiple functions including transmission, reception, and interference rejection, reducing the need for specialized components
