Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors are arranged with different intervals between connection portions and connection pads, then alignment and coupling become easier, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-positioning the first connector and connection pads at different intervals during the manufacturing process. The circuit board is designed with the first connector having connection portions at a first interval and connection pads at a second interval (different from the first interval) before final assembly. This pre-arranged interval difference creates built-in alignment features that guide the coupling process, making assembly easier while the intervals are established with precision during manufacturing.
2Device complexity
If the circuit board design eliminates bridge substrates, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies the extraction principle by removing the bridge substrate component from the system. Instead of using a separate bridge substrate to connect the circuit board to the main circuit board, the invention directly couples the first connector on the circuit board with the corresponding connector on the main circuit board. This eliminates an entire component layer, reducing device complexity and the number of assembly steps, while requiring precise positioning of the connectors which is achieved through the designed interval differences.
3Ease of operation
If connectors are spaced apart on the plane, then ease of coupling is improved, but area occupied increases
Solution Approach 1:
The patent applies dimensionality change by utilizing the third dimension (vertical spacing) to achieve ease of coupling. The first connector and connection pads are spaced apart in the planar direction, but this spacing is compensated by their vertical arrangement on the circuit board. The connection portions extend in a direction substantially perpendicular to the circuit board, allowing the connectors to be spaced apart horizontally while maintaining compact overall dimensions through vertical layering.
