Skeleton assembly of umbrella-shaped canopy on top of playpen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infant playpens with canopies face challenges in integrating the canopy skeleton with the playpen skeleton during folding, leading to design complexities and limited options for combined products.
Innovation Solution
A skeleton assembly for an umbrella-shaped canopy that includes a notch and multiple first support frames, which are extendable or retractable, and a connection base that can be fixedly clamped to the playpen's corner portion, allowing for quick mounting and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the canopy skeleton and playpen skeleton are assembled together, then the canopy provides mosquito protection, warming, and shading effects, but conflicts occur during folding making the design process difficult
Solution Approach 1:
The canopy structure is divided into independent modular components: connection bases that attach to playpen corners, first support frames that form the canopy skeleton, and a retractable rod mechanism. This segmentation allows each component to be optimized independently and simplifies the overall design while maintaining adaptability.
Solution Approach 2:
The support frames are designed with retractable rods that can extend and contract, transforming the static canopy structure into a dynamic one. This allows the canopy to adapt between extended (providing full coverage) and retracted (for storage or ventilation) states, resolving the conflict between functionality and folding complexity.
2Ease of operation
If the canopy skeleton is integrated with the playpen, then mounting and disassembly becomes convenient, but the folding mechanism becomes more complex
Solution Approach 1:
The connection base integrates multiple functions: it attaches to the playpen corner structure, provides mounting points for support frames, and incorporates the retractable rod mechanism. This merging reduces the number of separate components and simplifies the overall assembly process while maintaining ease of mounting and disassembly.
Solution Approach 2:
The retractable rod mechanism incorporates spring-loaded or elastic components that automatically extend or contract the support frames during folding and unfolding. This self-service mechanism reduces the need for complex manual operation while maintaining ease of use.
3Adaptability or versatility
If the first support frames are made extendable or retractable, then the canopy can be adjusted, but the structure becomes more complex
Solution Approach 1:
The first support frames incorporate retractable rods that can extend and contract along the frame length. This dynamic mechanism allows the canopy to adjust its size and shape to provide different levels of coverage while maintaining a relatively simple structural design through standardized components.
Solution Approach 2:
The retractable mechanism allows the support frames to change their effective length parameter, enabling the canopy to adapt between fully extended (maximum coverage) and partially retracted (reduced coverage or storage) states. This parameter adjustment provides versatility without requiring multiple different frame sizes.
