Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional ventilation channels are equipped with separate noise insulation materials, then noise insulation effectiveness is improved, but production cost and installation complexity increase
Solution Approach 1:
The patent combines the ventilation channel structure and noise insulation function into a single integrated element. The ventilation channel is formed directly within the insulating material element, eliminating the need for separate noise insulation materials and reducing construction complexity while maintaining noise insulation effectiveness.
Solution Approach 2:
The insulating material element serves multiple functions simultaneously: it provides noise insulation, forms the ventilation channel structure, and enables air exchange. This multi-functional design reduces the number of components needed and simplifies the overall ventilation system construction.
2Productivity
If multiple separate components are used to form ventilation channels, then ventilation effectiveness is improved, but installation time and production outlay increase
Solution Approach 1:
The patent merges multiple functions into a single element that provides both ventilation channels and noise insulation in one component, reducing the number of installation steps and time required while maintaining effective ventilation performance.
3Object-affected harmful factors
If complex curved ventilation channels are formed, then noise insulation is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes the inherent properties of insulating materials to form ventilation channels with varying geometries (rectilinear or curved) by changing the structural parameters of the material itself, allowing noise insulation enhancement without significantly increasing manufacturing complexity.
