Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sensor support substrate has high rigidity/stiffness to provide structural support, then structural stability is improved, but sensor displacement is limited and permanent damage to the fiber optic cable may occur
Solution Approach 1:
A viscoelastic material layer is introduced as an intermediary between the rigid sensor support substrate and the fiber optic cable. This intermediary layer allows controlled sensor displacement while the rigid substrate provides overall structural stability. The viscoelastic material absorbs and distributes forces, preventing permanent damage to the fiber optic cable while enabling sufficient sensor displacement for detection.
2Measurement precision
If the fiber optic cable is allowed to deform freely to enable sensor displacement, then signal sensitivity is improved, but permanent damage to the fiber optic cable may occur
Solution Approach 1:
The viscoelastic material serves as a cushioning layer positioned between the rigid substrate and the fiber optic cable before any external force is applied. This pre-positioned cushioning material prevents direct transmission of high forces that could cause permanent damage, while still allowing sufficient displacement for sensitive detection. The material absorbs and distributes mechanical stresses, protecting the fiber optic cable from damage.
3Ease of manufacture
If the fiber optic sensor is directly attached to the rigid substrate via bonding material, then installation simplicity is improved, but signal characterization and detection are adversely impacted
Solution Approach 1:
The attachment system is segmented into multiple functional layers: a bonding material layer for simple installation, a viscoelastic material layer for controlled displacement and signal enhancement, and the rigid substrate for structural support. This segmentation allows each layer to perform its specific function optimally while maintaining ease of installation through the bonding material interface.
