Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional acquisition device with frame and electronic modules is used, then data acquisition functionality is provided, but the device becomes bulky and requires extensive installation with cables and fixing screws
Solution Approach 1:
The device is divided into multiple electronic modules that can be independently stacked and connected. Each module contains its own electronic components and can be separately manufactured and assembled, reducing the overall complexity of installation while maintaining functionality.
Solution Approach 2:
Multiple electronic modules are combined into a single stacked assembly that functions as one integrated acquisition device. The modules are electrically connected through conductive tracks on opposing faces, eliminating the need for external cable connections and reducing installation complexity.
2Ease of operation
If a bulky acquisition device is installed close to sensors, then data acquisition is enabled, but the structure requires cable passages and drilling of holes for fixing screws
Solution Approach 1:
The device transitions from a planar configuration requiring surface mounting with screws to a three-dimensional stacked module configuration. This vertical stacking allows the device to be attached as a single unit without requiring multiple drilling operations or cable passages through the structure.
3Reliability
If the vehicle or equipment is instrumented with a fixed acquisition device, then measurements are obtained, but modification of sensor and wiring configuration becomes difficult
Solution Approach 1:
The acquisition device transitions from a static, fixed configuration to a dynamic, reconfigurable system. Modules can be added, removed, or rearranged in the stack to adapt to different measurement requirements, while maintaining reliable electrical connections through the conductive track interface.
Solution Approach 2:
Multiple electronic modules are pre-assembled into a stacked configuration before installation. This preliminary assembly allows for flexible configuration adjustments to be made during setup without requiring complex field modifications or rewiring operations.
4Device complexity
If electronic modules are stacked with conductive tracks on opposing faces, then electrical connections are established without cables, but connection reliability must be maintained under severe environmental conditions
Solution Approach 1:
The electrical connection system replaces traditional mechanical cable connections with integrated conductive tracks formed on the opposing faces of adjacent modules. This substitution eliminates cable routing complexity while providing robust electrical connections that are more resistant to environmental factors such as vibration and moisture.
