Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple stages of switches are used in a multi-channel switch device, then the signal transmission capability is improved, but the layout space increases
Solution Approach 1:
The patent combines multiple switch stages into a single integrated switch circuit that can perform multi-stage switching operations. The switch circuit includes multiple switching elements that can be configured in series to achieve the signal transmission capability of multiple discrete switch stages, thereby reducing the overall layout space while maintaining adaptability.
Solution Approach 2:
The patent implements a nested structure where switching elements are arranged in a hierarchical configuration within the single switch circuit. Inner switching elements are controlled by outer switching elements, creating a nested control architecture that enables multi-stage switching functionality in a compact form factor, effectively reducing layout space while preserving signal transmission capabilities.
2Adaptability or versatility
If multiple stages of switches are used in a multi-channel switch device, then the switching functionality is improved, but the device complexity increases
Solution Approach 1:
The patent designs a universal switch circuit that can perform multiple switching functions through a single integrated structure. The switching elements are configured to enable various switching configurations (series, parallel, nested) within the same circuit, allowing the device to achieve complex multi-stage switching functionality without proportionally increasing device complexity.
Solution Approach 2:
The patent implements dynamic control where the switching elements can be selectively activated or deactivated based on operational requirements. The nested and series configurations allow the circuit to adapt its effective complexity dynamically, enabling full multi-stage functionality when needed while simplifying to fewer active stages for simpler operations, thus managing device complexity flexibly.
