Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible connectors are used to connect measurement nodes in a point mode, then the flexible clinometer can adaptively deform to avoid damage, but the connectivity is poor and reliability is low
Solution Approach 1:
The flexible clinometer is divided into multiple measurement nodes (first measurement node, second measurement node, etc.) that are segmented along the flexible connector. Each node contains electronic components and sensing elements that can independently function while maintaining overall system flexibility. This segmentation allows the structure to adapt to deformations while preserving connection integrity through modular design.
Solution Approach 2:
The flexible connector utilizes composite material structure combining flexible substrate with conductive traces and bonding pads. The composite design integrates electrical connection pathways with mechanically flexible properties, enabling the connector to maintain electrical continuity while accommodating large deformations and bending stresses in landslide monitoring environments.
2Measurement precision
If traditional monitoring means are used for landslide deformation, then monitoring can be performed, but it is difficult to reflect the evolution features and deformation laws of a complete cycle of landslide deformation
Solution Approach 1:
The flexible clinometer employs continuous measurement nodes arranged along the flexible connector, enabling continuous monitoring of deformation throughout the complete landslide cycle. The multiple measurement nodes capture deformation evolution continuously from initial stages through failure, providing uninterrupted data for analyzing the complete deformation cycle and evolution characteristics.
Solution Approach 2:
The system incorporates data processing and analysis capabilities that provide feedback on deformation patterns and evolution trends. The measurement nodes continuously monitor and record deformation data, which is then processed to identify evolution features and deformation laws, enabling real-time feedback on landslide behavior throughout the complete monitoring cycle.
