Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional pipe shoes are used to support hot piping, then the pipe is mechanically supported, but acoustic propagation and thermal stress are not effectively dampened
Solution Approach 1:
The patent introduces acoustic isolators as intermediary elements positioned between the pipe and the pipe shoe support structure. These isolators serve as a mediator that decouples the direct mechanical connection, thereby dampening acoustic propagation and vibration transmission from the pipe to the support structure while maintaining mechanical support functionality.
Solution Approach 2:
The acoustic isolators are constructed from composite materials that combine acoustic damping properties with heat-resistant characteristics. This composite material approach allows the isolators to simultaneously address acoustic propagation dampening and withstand the thermal environment of hot piping systems.
2Object-affected harmful factors
If insulation materials are used for cold piping, then acoustic propagation is dampened, but the materials are inadequate for high temperature and compressive forces
Solution Approach 1:
The patent employs composite materials in the acoustic isolators that integrate the acoustic damping properties of insulation materials with the high-temperature resistance and compressive strength of refractory or heat-resistant materials. This composite construction enables the isolators to function effectively in hot piping environments where conventional insulation materials would fail.
Solution Approach 2:
The invention changes the material parameters of the acoustic isolators to withstand high temperatures and compressive forces. By selecting materials with appropriate thermal stability and mechanical strength parameters, the isolators can operate in elevated temperature environments while maintaining their acoustic damping functionality.
3Adaptability or versatility
If the pipe shoe base slides along the pipe rack surface, then thermal expansion is accommodated, but thermal stress is not effectively managed
Solution Approach 1:
The acoustic isolators act as an intermediary layer between the pipe shoe base and the pipe rack surface, providing a interface that accommodates thermal expansion movements while managing thermal stress. This intermediary layer allows for controlled movement and stress distribution.
Solution Approach 2:
The patent incorporates design features that explicitly account for thermal expansion, allowing the pipe shoe base to slide along the pipe rack surface while the acoustic isolators manage the associated thermal stress through their material properties and structural design.
