Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImprovestabilityVSAvoidcomplexity of assembly
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveease of assemblyVSAvoidservice life
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If conventional support bar attachment methods are used, then ease of assembly is improved, but stability and load-bearing capacity worsen

Engineering Contradiction:
Improveease of assemblyVSAvoidload-bearing capacity
Core Design Contradiction:
Ease of operationVSStrength

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

Inventive Principle:
Principle #40Composite materials
