Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a cap structure with grooves is used to hold and position connectors, then positioning accuracy is improved, but connector height cannot be reduced
Solution Approach 1:
The invention extracts the positioning function from the cap structure and relocates it to the connector housing itself through positioning protrusions and positioning holes. This separation allows the cap to focus solely on holding connectors through suction, while positioning accuracy is achieved through the dedicated positioning features on the connectors, enabling reduced connector height without compromising positioning precision
Solution Approach 2:
The invention introduces positioning protrusions on the connector housing that mate with positioning holes in the cap as an intermediary mechanism. This intermediary positioning system decouples the positioning function from the cap's holding structure, allowing the cap to use a simpler suction-based holding mechanism that accommodates reduced connector height while maintaining high positioning accuracy through the protrusion-hole interface
2Productivity
If connector height is reduced for miniaturization, then productivity is improved, but positioning accuracy deteriorates
Solution Approach 1:
The invention moves the positioning mechanism from the vertical dimension (cap groove structure) to the horizontal dimension (positioning protrusions on connector housing mating with positioning holes in cap). This dimensional shift allows reduced connector height in the vertical direction while maintaining positioning accuracy through horizontal protrusion-hole engagement, thus achieving miniaturization without sacrificing positioning precision
Solution Approach 2:
The positioning protrusions are pre-formed on the connector housing during connector manufacturing, establishing the positioning capability before the connectors are mounted on the board. This preliminary positioning feature ensures that even with reduced connector height, the connectors will achieve accurate positioning when the positioning protrusions engage with the positioning holes in the cap during the mounting process

AI summary
A housing has a first positioning hole that penetrates the housing in the vertical direction. A suction cap includes a suction plate part to be sucked by a suction nozzle, and a plurality of positioning protrusion parts, each of which is to be inserted into a first positioning hole of the housing of an input/output board-side connector and a CPU board-side connector in the state where the suction cap holds the input/output board-side connector and the CPU board-side connector. Each positioning protrusion part is inserted into each corresponding first positioning hole in the state where the suction cap holds the input/output board-side connector and the CPU board-side connector, which achieves the positioning of the input/output board-side connector and the CPU board-side connector with respect to the suction cap.
