Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support bar is attached to trampoline legs via intermediate pieces with lateral struts, then stability is improved, but device complexity and material requirements increase
Solution Approach 1:
The invention extracts the essential function of support bar attachment from the complex intermediate piece and strut assembly, simplifying the structure to directly connect the support bar to the trampoline frame while maintaining stability through optimized connection geometry and distribution of attachment points
Solution Approach 2:
The support bar connection system is designed to serve multiple functions: providing structural stability, enabling height adjustment, and facilitating easy assembly/disassembly, thereby replacing multiple separate components with a multi-functional integrated solution
2Ease of operation
If a clamping device is welded to the frame for holding the support bar, then ease of assembly is improved, but reliability and service life deteriorate
Solution Approach 1:
The connection system employs a nested structure where the support bar fits into a receptacle on the frame, with adjustable clamping elements that can be inserted and removed independently, allowing for easy assembly while maintaining strong mechanical connection through nested geometric interlocking
Solution Approach 2:
The frame is pre-equipped with recesses and connection elements during manufacturing, so that the support bar can be directly attached without requiring现场 welding or complex assembly steps, thereby maintaining both ease of assembly and structural reliability
3Ease of operation
If conventional support bar attachment methods are used, then ease of assembly is improved, but stability and load-bearing capacity worsen
Solution Approach 1:
The connection system utilizes composite construction combining the frame material with reinforced connection elements and clamping mechanisms, creating a hybrid structure that maintains ease of assembly while significantly enhancing load-bearing capacity through material optimization and structural reinforcement at critical connection points
