Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing semiconductor technologies are used for protection devices, then single-channel protection is provided, but multi-channel protection capability is insufficient
Solution Approach 1:
The protection device is divided into multiple independent conductive channels, each capable of handling transient voltage surges separately. The device includes a first conductive channel with first and second semiconductor chips, and a second conductive channel with third and fourth semiconductor chips, allowing simultaneous multi-channel protection operations
Solution Approach 2:
Multiple semiconductor chips are integrated into a single monolithic device structure with shared substrate layers and encapsulation. The first and second substrate layers provide common support for all four semiconductor chips, creating a unified multi-channel protection device that combines the functionality of multiple individual protection components
2Adaptability or versatility
If multiple semiconductor chips are integrated into a monolithic structure, then multi-channel protection is achieved, but device complexity increases
Solution Approach 1:
The first and second substrate layers serve multiple functions simultaneously: they provide mechanical support for all semiconductor chips, establish electrical connections between chips and external leads, and provide structural framework for the encapsulation process. This multi-functionality reduces the need for additional specialized components
Solution Approach 2:
The semiconductor chips are nested between the first and second substrate layers in a compact stacked arrangement. The fill material is then nested around the chips and substrate layers, creating a dense integrated structure where components are efficiently packed within the monolithic device housing
