Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal pipes are sleeved with multi-directional joints for firm connection, then connection reliability is improved, but the overall strength of the main structure is reduced due to overlapping
Solution Approach 1:
The connection structure is divided into separate functional components: a connection plate for joining metal pipes and a connection joint for multi-directional connection. This segmentation eliminates the need for sleeving, preventing overlap and maintaining the full length and strength of metal pipes while achieving reliable connections through the distributed connection points.
2Length of stationary object
If metal pipes are made long to achieve desired span, then construction span is improved, but overall strength is reduced due to overlapping with joints
Solution Approach 1:
The connection plate and connection joint are designed as separate segmented components that connect to the metal pipe at different locations. This allows the metal pipe to maintain its full length for achieving the desired construction span without any portion being overlapped or wasted in connection areas.
3Reliability
If sleeving is used to connect metal pipes and joints, then connection firmness is improved, but assembly difficulty increases due to tolerance issues
Solution Approach 1:
The connection system is segmented into a connection plate with multiple connection points and a separate connection joint. This eliminates the single-point sleeving connection that is sensitive to tolerance accumulation, distributing the connection function across multiple points and components for easier assembly while maintaining firmness.
Solution Approach 2:
The connection plate serves as an intermediary component between the metal pipe and the connection joint. It provides a standardized interface that mediates the connection, eliminating the need for precise tolerances in direct sleeving while ensuring firm connection through the multi-point attachment system.
4Reliability
If metal pipes are overlapped with joints for connection, then connection stability is improved, but material waste increases
Solution Approach 1:
The connection structure is segmented into separate components (connection plate, connection joint, metal pipe) that connect without overlapping. Each component maintains its full material integrity and length, eliminating the material waste that occurs when pipes are overlapped with joints for connection.
5Reliability
If overlapping connections are used, then connection reliability is improved, but production energy consumption increases
Solution Approach 1:
The segmented connection design eliminates overlapping, reducing the total material volume required for connections. This reduces the energy consumption associated with material production, processing, and transportation while maintaining connection reliability through the distributed multi-point connection system.
