Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a preformed solder part is used as solder depot, then the soldered connection can be produced, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The solder depot is extracted from being a separate preformed component and is instead formed in situ within the connector inner conductor. The radial solder receiving bore provides a cavity where solder wire can be placed and melted to create the solder depot directly at the connection point, eliminating the need for complex preformed solder parts and simplifying the assembly process.
Solution Approach 2:
The radial solder receiving bore acts as an intermediary structure that facilitates the creation of the solder depot. It provides a controlled cavity within the connector inner conductor that receives and contains the solder wire, enabling reliable soldered connections while simplifying the overall assembly process by integrating the solder depot formation into the connector structure itself.
2Reliability
If preformed solder parts are used, then soldered connection can be achieved, but the introduction of solder depot becomes complex
Solution Approach 1:
The complexity of introducing preformed solder parts is eliminated by extracting the solder depot formation process from external components and relocating it to the radial solder receiving bore within the connector inner conductor. This allows solder wire to be simply placed into the bore and melted, greatly simplifying the manufacturing process while maintaining reliable soldered connections.
Solution Approach 2:
The connector inner conductor with its radial solder receiving bore is designed to be self-sufficient for creating the solder depot. The bore structure itself provides the necessary cavity and containment for the solder wire, eliminating the need for separate preformed solder parts and complex introduction mechanisms. The structure serves its own function of creating and containing the solder depot.
3Reliability
If multiple radial solder receiving bores are used, then sufficient wetting of contact surface is achieved, but the connector inner conductor structure becomes more complex
Solution Approach 1:
The solder depot formation is segmented into multiple radial solder receiving bores distributed around the connector inner conductor. This segmentation allows the solder to wet multiple contact surfaces simultaneously, improving connection reliability. The bores are simple radial cavities that are straightforward to manufacture, so the structural complexity increase is minimal while achieving superior wetting coverage.
Solution Approach 2:
Each radial solder receiving bore provides localized solder depot formation at specific contact points around the connector inner conductor. This local quality approach ensures that each contact surface receives adequate solder wetting where needed, while the overall structure remains simple with just a few radially oriented bores in the connector inner conductor wall.
