Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for vibration isolation and load measurement, then each component can be optimized independently, but the installation complexity and device complexity increase
Solution Approach 1:
The patent combines the vibration isolation pad and load measurement sensor into a single integrated element. The load sensor is embedded within the vibration isolation pad structure, allowing simultaneous vibration isolation and load measurement functions in one component, thereby reducing installation complexity while maintaining both functions' performance
Solution Approach 2:
The integrated element serves multiple functions: it provides vibration isolation through the elastic material layer while simultaneously measuring load forces and tilting movements through the embedded sensor arrangement. This multi-functionality eliminates the need for separate components and simplifies the overall system
2Reliability
If separate components are used for vibration isolation and load measurement, then each component can be optimized independently, but the storage and supply efficiency decrease
Solution Approach 1:
By merging the vibration isolation pad and load sensor into one integrated element, the system reduces the number of separate parts that need to be stored, managed, and supplied to construction sites. This single-element approach improves storage efficiency and supply chain management while maintaining both vibration isolation and load measurement capabilities
3Ease of operation
If a combined element is used for vibration isolation and load measurement, then installation and storage are simplified, but the device structure becomes more complex
Solution Approach 1:
The integrated element is designed with a modular structure where the load sensor arrangement is segmented into discrete sensor elements that can be independently positioned within the vibration isolation pad. This segmentation allows for simplified manufacturing and assembly while achieving the desired structural integration
Solution Approach 2:
The elastic material layer serves as an intermediary between the rigid components, providing both vibration isolation and a medium for force transmission to the sensors. This intermediary element simplifies the structural design by creating a flexible connection that accommodates both functions without requiring complex rigid linkages
4Device complexity
If traditional separate components are used, then the system is simpler in structure, but tilting movement measurement capability is lost
Solution Approach 1:
The integrated element maintains the simplicity of a single-component system while adding multi-functionality. By embedding multiple sensor elements within the vibration isolation pad, the system gains tilting detection capability without requiring additional separate components, thus preserving structural simplicity while enhancing versatility
