Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional relay-based switch matrices are used, then signal routing functionality is achieved, but the system becomes large and expensive
Solution Approach 1:
The patent merges multiple relay functions into a single integrated switching element. The switching element integrates a first contact, second contact, third contact, and movable contact all within one device, eliminating the need for multiple separate relays. This consolidation reduces system size, component count, and cost while maintaining the ability to route signals between multiple inputs and outputs.
Solution Approach 2:
The switching element is designed as a universal component that can perform multiple switching functions simultaneously. By incorporating multiple contacts and a movable contact that can connect different input-output pairs, a single element replaces what would traditionally require multiple specialized relays, reducing overall system complexity while preserving routing versatility.
2Device complexity
If fewer relays are used to reduce size, then system compactness is improved, but blocking conditions become more likely
Solution Approach 1:
The patent combines multiple contact sets within a single switching element, creating redundant pathways internally. The first contact, second contact, third contact, and movable contact work together to provide alternative routing options, ensuring that signal flow is maintained even when certain contact combinations are engaged, thereby preventing blocking conditions.
Solution Approach 2:
The switching element is designed with built-in redundancy before blocking can occur. The multiple contact arrangements and alternative pathways are pre-configured within the element structure, providing cushioning against blocking conditions by ensuring that if one path is occupied, other paths remain available for signal routing.
3Strength
If integrated PWB switching elements are used, then system robustness and power handling are improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates multiple contact elements and switching mechanisms into a single PWB-mounted switching element. This consolidation allows the robust power handling capabilities of multiple contacts to be achieved within one manufacturable unit, balancing the need for high power handling with manufacturing efficiency through integrated construction.
