Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single bridge connector is used to connect adjacent sensing pads, then the manufacturing process is simpler, but the connection reliability deteriorates because the bridge connector is easy to break during manufacturing
Solution Approach 1:
The patent divides the single bridge connector connection into multiple bridge connectors (first bridge connector and second bridge connector) connected in cascade between adjacent sensing pads. This segmentation increases connection reliability by providing redundant connection paths while maintaining manufacturing simplicity through the modular cascade structure.
Solution Approach 2:
The patent implements a bridge connector structure with insulating layers and protective designs before manufacturing defects can occur. The multi-connector cascade arrangement provides beforehand cushioning against potential breakage during the manufacturing process, ensuring that if one connector fails, others can maintain the connection.
2Reliability
If multiple bridge connectors are used to connect adjacent sensing pads, then the connection reliability improves, but the device complexity increases
Solution Approach 1:
The patent designs the multiple bridge connectors to serve universal functions: electrical connection, signal transmission, and mechanical support. The first and second bridge connectors perform identical multi-functional roles, allowing the system to achieve higher reliability without proportionally increasing overall device complexity through standardized multi-functional components.
Solution Approach 2:
The patent arranges the first and second bridge connectors in different spatial dimensions or layers, creating a three-dimensional cascade connection structure. This dimensional arrangement increases connection reliability through redundant paths while managing complexity by organizing connectors in structured spatial relationships rather than random arrangements.
3Manufacturing precision
If the bridge connector size is reduced to meet high accuracy requirements, then the sensing precision improves, but the connection reliability deteriorates because smaller connectors are more fragile
Solution Approach 1:
The patent segments the connection function across multiple small bridge connectors rather than relying on a single larger connector. Each small connector meets the high accuracy requirements for compact design, while the collective cascade arrangement of multiple connectors provides the necessary mechanical strength and reliability that a single small connector could not achieve alone.
Solution Approach 2:
The patent combines multiple small bridge connectors in a cascade configuration to achieve the cumulative strength and reliability equivalent to or greater than a single larger connector. This merging approach allows the system to maintain small connector sizes for accuracy while achieving high reliability through the combined structural integrity of multiple connected elements.
