Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collapsible infant bed mechanisms are expensive, difficult to manufacture, and have reliability issues, with existing designs often lacking simplicity and ease of operation while failing to achieve a compact collapsed state effectively.
Innovation Solution
A collapsible infant bed frame with a top frame, legs, support frames, and links that pivot to allow for easy transition between stretched and collapsed states, featuring a sliding mechanism and inverted V-shape design to reduce volume and facilitate quick collapse, while maintaining firm engagement and low manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional collapsing mechanisms are used, then the infant bed can be collapsed, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The frame body is divided into multiple top frames and leg assemblies that can independently pivot and collapse. Each top frame is connected to legs through separate pivot connections, allowing modular collapse without requiring a complex centralized mechanism.
Solution Approach 2:
Instead of using a complex centralized collapsing mechanism from below the bassinet floor, the patent uses simple pivot connections at the corners where top frames connect to legs. This inverted approach places the collapsing function at the peripheral connection points rather than the center, simplifying the overall structure.
2Productivity
If conventional collapsing mechanisms are used, then the infant bed can be collapsed, but manufacturing and combination difficulty increases
Solution Approach 1:
The infant bed is divided into independent leg assemblies and top frame sections that can be manufactured separately and then assembled through simple pivot connections. This segmentation allows for easier manufacturing and combination compared to a monolithic collapsing mechanism.
Solution Approach 2:
The patent inverts the conventional approach by placing simple pivot connections at the corner connections between top frames and legs, rather than using a complex centralized mechanism. This inversion makes each component simpler to manufacture and easier to assemble.
3Volume of moving object
If the infant bed is collapsed effectively, then the volume is reduced, but the engagement firmness may be compromised
Solution Approach 1:
The pivot connections are designed with predetermined engagement positions that ensure firm engagement when the bed is collapsed. The top frames and legs are configured to naturally align and lock into place during the collapsing motion, providing reliable engagement without requiring additional locking mechanisms.
Solution Approach 2:
The pivot connections use curved or rounded surfaces that guide the top frames and legs into proper alignment during collapse. This curvature ensures smooth motion and reliable engagement at the final collapsed position, maintaining firmness while achieving compact volume.
