Foldable Bed Frame with Pivoting Bedding Support Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable bed frames are inconvenient to use due to the difficulty in unlocking telescopically coupled bars and require separate detachment of bedding supports for folding and unfolding, making them time-consuming and cumbersome.
Innovation Solution
The design includes a bedding support assembly with linking mechanisms that allow the bedding support to pivotally connect with the bed frame, and adjustable supports with a locking and unlocking mechanism using inner and outer tubular bars, enabling easy folding and unfolding of the bed frame while maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopically coupled bars with push buttons are used to connect legs, then the bed frame can be folded, but the push buttons require very hard pressure to unlock the bars
Solution Approach 1:
A cam mechanism acts as an intermediary between the push button and the locking surfaces. When the button is pressed, the cam rotates and uses its geometric shape to amplify the unlocking force, reducing the direct force requirement on the button while still effectively releasing the locked state
Solution Approach 2:
The locking mechanism transitions from a direct force-application design to one that uses mechanical advantage through cam geometry. The cam profile changes the force parameters by converting small button pressure into larger unlocking forces through rotational motion and lever arms
2Adaptability or versatility
If bedding supports are attached separately to the bed frame, then they can provide support functionality, but they cannot be folded or unfolded along with the bed frame components
Solution Approach 1:
The bedding support structure is merged with the bed frame's leg assembly through linking mechanisms. The support's left and right segments are connected to the respective legs via links, creating a unified structure that moves together during folding and unfolding operations
Solution Approach 2:
The bedding support transitions from a static, fixed attachment to a dynamic, movable connection. The linking mechanisms with pivot points allow the support to change its configuration and position relative to the bed frame, enabling it to adapt during folding and unfolding while maintaining structural integrity
3Loss of time
If bedding supports are attached separately to the bed frame, then they can provide support functionality, but they require detachment and removal for folding and unfolding operations
Solution Approach 1:
The bedding support structure is merged with the bed frame's leg assembly through linking mechanisms. The support's left and right segments are connected to the respective legs via links, creating a unified structure that moves together during folding and unfolding operations
Solution Approach 2:
The bedding support transitions from a static, fixed attachment to a dynamic, movable connection. The linking mechanisms with pivot points allow the support to change its configuration and position relative to the bed frame, enabling it to adapt during folding and unfolding while maintaining structural integrity
