Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the holding bar is secured to the leg via intermediate piece and lateral struts, then the trampoline is stable, but it requires large amount of material and complicated assembly
Solution Approach 1:
The holding bar assembly is divided into separate components: the bar itself, the guide secured to the frame, and the inner piece received in the guide. This segmentation allows for simpler assembly where components are independently manufactured and then assembled together, reducing the complexity compared to the previous integrated strut structure.
Solution Approach 2:
The holding bar is extracted from the leg structure and repositioned to be secured directly to the frame via the guide. This removes the need for intermediate pieces and lateral struts connecting the bar to the legs, simplifying the overall structure while maintaining stability through the frame-mounted guide.
2Ease of manufacture
If the holding bar is secured by clamp device welded onto frame, then the construction is simple and easy to assemble, but the useful life is limited under high loads
Solution Approach 1:
The inner piece is designed to be movable within the guide, allowing dynamic adjustment of the holding bar height and position. This movability enables the structure to adapt to different load conditions and usage scenarios, enhancing reliability while maintaining ease of assembly through a simple insertion mechanism.
Solution Approach 2:
The height and position of the holding bar can be adjusted by moving the inner piece within the guide, changing the geometric parameters of the structure. This adjustability allows optimization for different load conditions and usage requirements, extending the useful life under varying high-load scenarios.
3Ease of operation
If the bar is height-adjustable in the guide, then the assembly is easy and maintenance is simplified, but the clamping mechanism must withstand high loads during intensive use
Solution Approach 1:
The guide and inner piece are designed with cylindrical geometries, allowing the inner piece to move smoothly within the guide through rotational or linear motion. This curved geometry simplifies the adjustment mechanism while the distributed contact surfaces maintain high clamping strength to withstand intensive use.
