Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a skeletal structure is used for assembly in conventional reed relays, then the assembly process can be simplified, but the position tolerance and precision of the reed switch cannot be guaranteed
Solution Approach 1:
The patent replaces the traditional mechanical skeletal structure with a PCB base that uses surface mount technology for component placement. The PCB provides precise positioning through its manufactured structure, eliminating the need for manual assembly on skeletal frameworks while ensuring consistent position tolerance and precision across mass-produced units.
2Ease of operation
If manual assembly is used for reed relay production, then flexibility is maintained, but production efficiency is reduced
Solution Approach 1:
The patent enables complete mechanization by replacing manual assembly operations with automated surface mount technology. The PCB base design with standardized mounting features allows robotic pick-and-place machines to precisely position and solder components, achieving both high production efficiency and consistent quality in mass production environments.
3Adaptability or versatility
If secondary processing of the reed switch is required, then assembly flexibility is maintained, but position tolerance and precision become difficult to guarantee
Solution Approach 1:
The patent incorporates the reed switch directly into the PCB base design with pre-defined mounting positions and electrical connections. The reed switch is positioned and secured during the initial surface mount assembly process without requiring secondary processing operations, ensuring that position tolerance and precision are maintained throughout the entire production cycle.
