Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a handrail is attached to conventional trampolines using existing solutions, then the handrail can be securely attached, but the material costs are high and the assembly process is complex

Engineering Contradiction:
Improvesecure attachmentVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment device is divided into separate modular components: a first attachment element that connects to the trampoline frame, a second attachment element that connects to the trampoline leg, and a tensioning element that joins them together. This segmentation allows each component to be independently manufactured and assembled, reducing overall complexity while maintaining secure attachment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment elements are designed with pre-formed connection interfaces and attachment points that are prepared in advance. The sockets, connection points, and tensioning mechanisms are pre-configured to enable straightforward assembly without requiring complex field modifications or custom fabrication during installation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If existing handrail attachment solutions are used, then secure attachment is achieved, but material costs are high

Engineering Contradiction:
Improvesecure attachmentVSAvoidmaterial cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The attachment device uses simple, easily manufactured components such as metal brackets, bolts, and tensioning elements that can be produced at low cost. These components are designed to be functional and durable without requiring expensive materials or complex manufacturing processes, making the overall attachment solution cost-effective.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The attachment elements are designed with universal connection interfaces that can accommodate different trampoline frame and leg configurations. The sockets and connection points are standardized to work with various trampoline types, eliminating the need for custom-made attachment solutions for each specific trampoline model and reducing material costs through standardized production.

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

3Adaptability or versatility

If the rod holder is designed to accommodate various trampoline geometries and suspension types, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvecompatibility with trampoline typesVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment elements feature universal connection interfaces with sockets and connection points that can accommodate different trampoline frame shapes, sizes, and leg configurations. The tensioning element can be adjusted to work with various suspension types (springs or rubber ropes) without requiring design modifications, achieving versatility through a standardized modular architecture.

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

Solution Approach 2:

The tensioning element is designed to be adjustable and movable, allowing it to adapt to different distances and angles between the frame and leg. This dynamic adjustment capability enables the same attachment device to accommodate various trampoline geometries without requiring multiple specialized designs, reducing overall device complexity while maintaining high adaptability.

Inventive Principle:
