Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional PCB layouts with limited conductive pad arrangements are used, then the assembly process is simpler, but the device size cannot be reduced and space utilization is poor
Solution Approach 1:
The patent transitions from traditional single-row or dual-row conductive pad arrangements to a three-dimensional spatial configuration with conductive pads arranged in multiple rows (first row at bottom end, second row at front end, third row at rear end) across different faces of the PCB. This dimensional expansion allows more connection points within a smaller footprint, reducing overall device size while maintaining connectivity requirements.
Solution Approach 2:
The conductive pads are segmented into three distinct rows positioned at different locations on the PCB (bottom end, front end, rear end), with each row serving specific connection functions. The board-mount connector connects to the first row, plug-in connectors connect to the second row, and additional connections are made at the third row. This segmentation enables optimized space utilization and reduces device dimensions.
2Adaptability or versatility
If more conductive pads and connectors are added to increase functionality, then interconnection efficiency improves, but the device size and structural complexity increase
Solution Approach 1:
The patent implements a nested arrangement where multiple conductive pad rows are integrated into a compact PCB structure. The first row of conductive pads is arranged on a first face of the PCB, while the second and third rows are arranged on a second face opposite the first face, creating a nested three-dimensional configuration that maximizes interconnection efficiency within minimal PCB area.
Solution Approach 2:
By utilizing both faces of the PCB and arranging conductive pads in three rows across different locations and orientations, the patent achieves high interconnection efficiency without proportionally increasing PCB area. The perpendicular arrangement of the first and second rows, along with the third row at the rear end, creates efficient spatial utilization.
3Area of stationary object
If perpendicular arrangements of conductive pads are used, then space utilization improves, but manufacturing precision requirements increase
Solution Approach 1:
The conductive pads are divided into three separate rows positioned at distinct locations on the PCB (bottom end, front end, rear end), with each row having its own set of connection requirements. This segmentation allows for modular manufacturing and assembly processes, where each row can be independently managed, reducing the overall precision burden compared to a single complex arrangement.
Solution Approach 2:
The nested configuration of conductive pad rows across different PCB faces and locations enables efficient space utilization while distributing manufacturing precision requirements across multiple independent connection points, making the overall manufacturing process more manageable.
