Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playard bed frames are complicated to operate, making it difficult for users to fold and unfold them efficiently, resulting in a poor user experience.
Innovation Solution
A one-button foldable bed frame design featuring a base, brackets, and folding mechanisms with a connecting rod assembly and sliding member that allows for quick unfolding and folding, facilitated by a locking mechanism for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking devices are used on each side of the playard, then the bed frame can be securely locked, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple independent locking devices into a single centralized locking mechanism. Instead of requiring separate locking operations for each side of the playard, the invention integrates all locking functions into one unified system that can be operated simultaneously, reducing the number of steps from four separate locking actions to a single locking operation.
Solution Approach 2:
The centralized locking mechanism serves multiple functions: it locks all four sides of the playard simultaneously, provides both locking and unlocking functions through a single device, and enables both folding and unfolding operations through one operational interface. This multi-functional design eliminates the need for separate locking devices on each side.
2Reliability
If multiple separate locking operations are required, then each side can be independently secured, but the folding efficiency decreases and user experience deteriorates
Solution Approach 1:
The invention merges the locking operations for all four sides into a single simultaneous action. The centralized locking mechanism engages all locking points at the same time, ensuring that each side is securely locked while completing the operation in one step rather than requiring sequential operations for each side.
Solution Approach 2:
The locking mechanism is designed to pre-position and simultaneously engage all locking components before the folding operation begins. The structural design ensures that when the single locking action is performed, all sides are already prepared and aligned for simultaneous locking, maximizing folding efficiency while maintaining security.
3Stability of the object's composition
If a complex multi-step folding process is used, then each component can be properly positioned, but the operation becomes difficult to manage and time-consuming
Solution Approach 1:
The invention combines multiple positioning steps into a single unified folding action. The centralized locking mechanism and integrated structural design allow all components to be positioned and locked simultaneously through one operational sequence, rather than requiring separate positioning operations for each component.
Solution Approach 2:
The folding mechanism incorporates dynamic elements that automatically guide components into their correct positions during the folding process. The structure is designed to naturally align and position each component as it moves, eliminating the need for manual positioning adjustments and reducing the overall operation time while maintaining positioning accuracy.
