Folding Bed Bracket with Lean Leg Bars for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding bed designs with X-shaped frames are prone to deformation and fail load tests when used with wider beds, due to excessive force on leg bars, resulting in poor performance and reduced service life.
Innovation Solution
The enhanced folding bed bracket incorporates lean leg bars and linkage mechanisms between bar members, allowing the lean leg bars to fold and unfold with the frame, distributing force more evenly and increasing structural strength without affecting the folding/unfolding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bed width is increased for better comfort, then the usability is improved, but the leg bars receive excessive force causing deformation and failure
Solution Approach 1:
The support frame is divided into multiple leg bars (front left, front right, rear left, rear right leg bars) that separately bear the load. This segmentation distributes the force from the widened bed across multiple structural elements rather than concentrating it on fewer bars, preventing deformation while maintaining adaptability to different bed widths
Solution Approach 2:
The patent introduces a spatial arrangement where leg bars are positioned at different locations (front and rear, left and right) and oriented at specific angles relative to the ground. This three-dimensional distribution of support points creates a more robust structural framework that can accommodate wider bed dimensions while maintaining sufficient strength through geometric optimization
2Strength
If reinforcement structures are added to improve strength, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The T connecting member serves multiple functions: it connects the fulcrum bars to form the X-shaped frame, provides attachment points for multiple leg bars, and enables the folding mechanism. This multi-functional design strengthens the bracket structure without adding separate reinforcement components, thereby avoiding increased complexity
Solution Approach 2:
The patent combines the support function and the folding mechanism into a unified structure where the same bar members and connecting components serve both structural reinforcement and articulation purposes. The leg bars are integrated into the existing frame geometry rather than being added as separate reinforcement elements, maintaining structural simplicity while achieving the required strength

AI summary
A enhanced folding bed bracket, lean leg bars are installed on both sides of the X shaped folding bracket for dispersing the force received by the bracket, the lean leg bars are linked with the leg bars of the bracket through connecting member, thereby the lean leg bar can be folded or unfolded along with the fold or unfold of the fold folding frame. The strength of the bracket is increased, in the mean time the folding or unfolding is not affected. The improved enhanced folding bed bracket, its bracket receives much less force, is not easy to be deformed and folding and unfolding are easy.
