Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the circuit board assembly is designed with fixed dimensions and components, then manufacturing precision is maintained, but adaptability deteriorates as design changes require new components and manufacturing resources
Solution Approach 1:
The circuit board assembly incorporates adjustable elements that allow dynamic reconfiguration of terminal positions and header connections. The connection matrix and matrix connector enable the header to be positioned at multiple locations without requiring physical changes to the circuit board itself, transforming a static design into a dynamically adaptable system.
Solution Approach 2:
The connection matrix serves multiple functions: it provides solder pads for electrical connections, defines terminal positions, and enables header placement at various locations. This multi-functional element allows the same circuit board design to serve multiple configuration needs, eliminating the requirement for separate designs for each terminal arrangement.
2Adaptability or versatility
If the header position is fixed relative to the circuit board, then manufacturing simplicity is maintained, but adaptability deteriorates as terminal positions cannot be adjusted
Solution Approach 1:
The connection system is segmented into distinct components: the connection matrix with multiple solder pad locations and the matrix connector that interfaces with the header. This segmentation allows the header to connect to different segments (solder pads) of the connection matrix, enabling position adjustment while keeping the overall assembly process simple and standardized.
3Adaptability or versatility
If design changes are implemented through new manufacturing components, then adaptability improves, but loss of time and resources increases due to additional design review and manufacturing setup
Solution Approach 1:
The connection matrix is pre-configured with multiple potential connection points and solder pad locations during the initial design phase. This preliminary preparation of multiple connection options eliminates the need for subsequent design changes, tooling modifications, or manufacturing setup changes when terminal positions need to be adjusted, saving significant time and resources.
4Adaptability or versatility
If multiple connection matrices and matrix connectors are used, then adaptability improves for reconfigurable assemblies, but device complexity increases
Solution Approach 1:
The connection matrix and matrix connector are designed as integrated components that work together as a unified system. The matrix connector is specifically configured to mate with the connection matrix, creating a standardized interface that simplifies the overall connection system despite enabling multiple configuration options. This merging reduces the complexity that would arise from using separate, incompatible connection elements.
