Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If acoustic panels are threadedly connected, then assembly is simplified, but gaps appear at joints reducing acoustic insulation
Solution Approach 1:
The connection structure is segmented into multiple functional components: positioning grooves for alignment, positioning cylinders for stable engagement, fixing blocks for mechanical connection, and sealing assemblies for gap closure. This segmentation allows each component to perform its specific function optimally while working together to eliminate gaps and maintain acoustic insulation.
Solution Approach 2:
The sealing assembly acts as an intermediary element between the positioning cylinder and the joint space. It includes a sealing block that fills and seals the gap at the joint, preventing sound transmission through the connection interface while allowing the mechanical connection to function.
2Reliability
If positioning grooves and cylinders are added to eliminate gaps, then acoustic insulation improves, but device complexity increases
Solution Approach 1:
Multiple functions are merged into integrated components. The fixing block combines mechanical connection and positioning functions. The positioning cylinder integrates alignment, connection, and sealing support functions. The sealing assembly merges gap filling and acoustic sealing functions. This merging reduces the number of separate components while achieving multiple objectives.
Solution Approach 2:
The positioning cylinder serves multiple purposes: it provides mechanical connection between panels, ensures precise alignment through the positioning groove, supports the sealing assembly, and maintains the structural integrity of the joint. This multi-functionality reduces the need for separate components for each function.
3Reliability
If sealing assemblies with springs and wire ropes are used, then gap sealing improves, but manufacturing complexity increases
Solution Approach 1:
The sealing assembly incorporates springs that provide dynamic sealing pressure. The springs automatically adjust to maintain contact between the sealing block and the joint surface, compensating for manufacturing tolerances and installation variations. This dynamic mechanism ensures reliable sealing without requiring extremely precise manufacturing.
Solution Approach 2:
The spring-based sealing assembly is self-adjusting and self-sealing. The springs automatically exert force to push the sealing block into the gap, maintaining sealing pressure without external intervention. The wire rope mechanism allows the sealing components to self-position and self-adjust during assembly.
