Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If secondary pouring is performed for molding the plug, then the plug signal terminals can be molded together with the plug insulator, but the production process becomes tedious and efficiency decreases
Solution Approach 1:
The plug components are divided into two separate manufacturing stages: the plug insulator is molded first, then the plug signal terminals are inserted into pre-formed insertion grooves on the plug insulator. This segmentation eliminates the need for secondary pouring, simplifying the molding process while maintaining production efficiency.
Solution Approach 2:
The insertion grooves are pre-formed on the plug insulator during the first molding process. This preliminary action allows the plug signal terminals to be simply inserted later without requiring additional molding operations, thus improving productivity while keeping the manufacturing process simple.
2Stability of the object's composition
If secondary pouring is performed for molding, then the plug structure can be integrated, but the production process becomes complex and time-consuming
Solution Approach 1:
The manufacturing process is segmented into two independent stages: molding the plug insulator with integrated insertion grooves, and separately preparing and inserting the plug signal terminals. This segmentation reduces production time while maintaining the integrated structure through precise insertion and positioning mechanisms.
Solution Approach 2:
The insertion grooves act as intermediaries that connect the plug insulator and plug signal terminals. These grooves are pre-formed on the plug insulator and receive the plug signal terminals, enabling structural integration without requiring time-consuming secondary pouring operations.
3Ease of manufacture
If the plug insulator is molded with integrated signal terminals, then manufacturing is simpler, but ultra-small spacing cannot be achieved
Solution Approach 1:
The plug components are manufactured separately with high precision: the plug insulator is molded with precisely positioned insertion grooves, and the plug signal terminals are separately prepared with matching dimensions. This segmentation enables ultra-small spacing precision to be achieved through precise insertion rather than integrated molding.
Solution Approach 2:
The mechanical connection between plug signal terminals and plug insulator is achieved through precise insertion into grooves rather than through integrated molding. This substitution allows for ultra-small spacing precision to be achieved through mechanical fitting and positioning after molding.
