Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connecting structure is used to connect handrails and columns, then the connection is stable, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The connecting structure is divided into separate components: a connecting component with engaging slots and engaging components with engaging protrusions. This segmentation allows each part to be independently manufactured and assembled, simplifying the overall assembly process while maintaining connection stability through the interlocking engaging structures.
Solution Approach 2:
The engaging components act as intermediary elements between the handrails and columns. These engaging components with protrusions fit into slots on the handrails and connect to the columns, serving as a mediator that simplifies the connection process while ensuring stable assembly.
2Reliability
If a conventional connecting structure is used, then the connection is stable, but the structure becomes complex
Solution Approach 1:
The connecting structure is segmented into modular components: connecting components with slots and engaging components with protrusions. This modular segmentation reduces structural complexity by breaking down a complex integrated structure into simpler, standardized parts that are easier to manufacture and assemble.
Solution Approach 2:
The design changes the geometric parameters of the connecting structure by using standardized slot and protrusion dimensions. This parameter standardization simplifies the overall structure while maintaining connection stability, as the standardized parameters ensure proper fit and strength without requiring complex custom designs.
3Reliability
If the playard frame is assembled in a conventional manner, then the structure is stable, but the packaging size becomes large
Solution Approach 1:
The playard frame is segmented into separable components (handrails, columns, and engaging components) that can be disassembled and compactly packaged. This segmentation allows the components to be nested or stacked in a reduced volume while maintaining structural stability through the engaging slot-protrusion connection system during assembly.
Solution Approach 2:
The disassembled components of the playard frame can be nested within each other during packaging, with smaller components fitting inside larger ones. This nesting arrangement significantly reduces the packaging volume while the components retain their structural integrity for stable reassembly.
