Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional connector with multiple contacts is used on the circuit board, then reliable electrical connections are achieved, but the area occupied by the connector increases, leaving insufficient space for antenna installation
Solution Approach 1:
The connector is divided into multiple independent contact units, each contact being a separate element that can be independently connected to lands. This segmentation allows for optimized spatial arrangement and reduced overall connector footprint while maintaining reliable electrical connections through multiple discrete contact points.
Solution Approach 2:
The contacts are arranged in a multi-dimensional configuration on the circuit board, utilizing both horizontal and vertical spacing optimization. By strategically positioning contacts in different dimensions and orientations, the connector achieves compact footprint while ensuring adequate connection reliability through distributed contact points.
2Area of stationary object
If the connector size is reduced to free up space for antenna installation, then antenna performance is improved, but the complexity of designing and manufacturing the compact connector increases
Solution Approach 1:
The connector design uses standardized segmented contact units that can be manufactured independently and then assembled or soldered to the circuit board. This modular approach simplifies manufacturing by allowing each contact to be produced using standard processes, reducing the overall complexity despite the compact size requirements.
Solution Approach 2:
The connector dimensions and contact spacing are optimized by adjusting geometric parameters within manufacturing tolerances. By carefully selecting and optimizing dimensional parameters, the connector achieves reduced footprint while remaining compatible with standard manufacturing processes and assembly techniques.
3Device complexity
If multiple contacts are connected to the same land, then the number of lands required is reduced, but the current density and stress on each connection point increases
Solution Approach 1:
Multiple contacts are deliberately connected to shared lands, merging multiple electrical pathways into common connection points. This merging reduces the total number of discrete lands required on the circuit board, simplifying the overall layout and reducing board complexity, while the land design is optimized to distribute and handle the combined current load and mechanical stress.
