Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the quantity of input/output interfaces is increased to meet diverse industrial demands, then the functionality and adaptability are improved, but the motherboard size increases resulting in impractical dimensions
Solution Approach 1:
The patent divides the interface expansion functionality into separate adapter circuit boards that can be independently added to the motherboard. Each adapter board provides specific I/O interfaces without requiring the entire motherboard to be enlarged, thus segmenting the interface provision from the main motherboard structure.
Solution Approach 2:
The patent utilizes the height dimension by stacking adapter circuit boards vertically on the motherboard surface. This allows multiple I/O interfaces to be added without increasing the motherboard's planar area, effectively transitioning from two-dimensional expansion to three-dimensional arrangement.
2Quantity of substance
If the motherboard size is increased to accommodate more input/output interfaces, then the interface quantity is improved, but the device becomes less practical for application
Solution Approach 1:
The interface expansion is achieved through separate, modular adapter boards rather than enlarging the main motherboard. This segmentation allows the motherboard to remain compact and practical while still providing numerous I/O interfaces through add-on modules.
Solution Approach 2:
The adapter circuit boards serve as universal interface providers that can be configured with different types of I/O interfaces based on specific industrial requirements. This multi-functionality allows a single compact motherboard to support diverse interface needs without physical enlargement.
3Adaptability or versatility
If adapter circuit boards are added to expand functionality, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The adapter circuit boards are designed to be dynamically addable and removable from the motherboard, allowing the system configuration to be adjusted based on specific needs. This dynamic modularity enables functionality expansion without permanently complicating the base device structure.
Solution Approach 2:
The adapter circuit boards act as intermediary components between the motherboard and various I/O devices. These intermediaries provide standardized connection interfaces that simplify the overall system integration, reducing complexity by creating uniform interface layers.
