Engineering Contradiction Analysis
1Reliability
If traditional soldering and assembly methods are used to mount command devices on printed circuit boards, then reliable electrical connection is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The command device is divided into separate modular components (actuator, contactor, holding means) that can be independently assembled and replaced. The holding means serves as a separate mounting component that interfaces with both the PCB and the command device components, eliminating the need for complex soldering while maintaining reliable electrical connections through the contactor's electrical contacts.
Solution Approach 2:
The holding means acts as an intermediary component between the printed circuit board and the command device components. It provides both mechanical support and electrical connection pathways, simplifying the overall assembly process by consolidating mounting and electrical connection functions into a single intermediate component that requires no soldering.
2Ease of operation
If traditional assembly methods with multiple components are used, then functional requirements are met, but assembly time and complexity increase
Solution Approach 1:
The holding means is pre-configured with both mechanical mounting features (attachment means for PCB integration) and electrical connection features (electrical contacts for connecting to the contactor) before assembly. This preliminary preparation allows for rapid assembly of the command device components without requiring complex multi-step procedures during the actual assembly process.
Solution Approach 2:
The holding means combines multiple functions into a single component: mechanical mounting to the PCB, electrical connection provision, and structural support for the actuator and contactor. This merging of functions reduces the number of separate components and assembly steps required, thereby reducing assembly time and complexity.
