Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pressure sensing devices are re-designed and re-manufactured for different sensing ranges, then the sensing range can be adjusted, but the manufacturing time and cost increase
Solution Approach 1:
The pressure sensing device is divided into multiple independent pressure sensing units that can be spliced together in different configurations. Each unit has standardized contact structures that enable modular assembly, allowing the sensing range to be adjusted by simply connecting or disconnecting units rather than re-manufacturing the entire device.
Solution Approach 2:
The pressure sensing units are designed with universal interfaces and standardized structures that allow them to function in multiple configurations. The same basic unit can be used in different sensing ranges by varying the number of units spliced together, eliminating the need for custom manufacturing for each application.
2Adaptability or versatility
If pressure sensing devices are re-designed for different sensing ranges, then the sensing range can be adjusted, but the device complexity increases
Solution Approach 1:
By segmenting the device into identical or similar modular units with standardized interfaces, the design complexity is reduced. Each module follows the same design patterns, making the overall system simpler to design and manufacture compared to creating custom devices for each sensing range.
Solution Approach 2:
The pressure sensing units are designed to nest or splice together in a standardized manner, where each unit contains the necessary components in a compact arrangement. This nested structure allows multiple units to be combined without proportionally increasing the overall complexity.
3Ease of manufacture
If fixed-range pressure sensing devices are used, then the manufacturing process is simple, but the flexibility to adjust sensing range immediately is lost
Solution Approach 1:
The pressure sensing device transitions from a fixed configuration to a dynamic, reconfigurable system. The splicable units can be easily connected or disconnected to change the sensing range on-demand, providing operational flexibility while maintaining manufacturing simplicity through standardized modular components.
Solution Approach 2:
The use of flexible circuit boards and thin-film structures in the pressure sensing units enables easy connection and disconnection without complex mechanical assemblies. The flexible nature of these components allows for simple splicing operations that maintain ease of manufacture while providing range adjustment flexibility.
