Lightweight foldable bed with reinforcing unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable beds are heavy and costly due to the need for reinforcing structures to prevent deformation under user weight, which limits their lightweight and cost-effective design.
Innovation Solution
A lightweight foldable bed design featuring a reinforcing unit with a first and second base frame that can convert between folded and unfolded positions, utilizing a first and second rod with a reinforcing plate that distributes pressure from a jack member to stabilize the base frames, reducing the likelihood of deformation and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional reinforcing structures (reinforcing bars and connection bars) are used to prevent deformation, then structural stability is improved, but weight and cost increase
Solution Approach 1:
The patent applies local reinforcement by positioning reinforcing plates only at critical stress points where the rods connect to base frames, rather than using continuous reinforcing bars throughout the structure. This localized approach provides necessary structural stability while minimizing additional weight compared to conventional full-perimeter reinforcing structures.
Solution Approach 2:
The patent combines different structural elements (rods, reinforcing plates, base frames) to create a composite structure that achieves both lightweight properties and structural stability. The reinforcing plates act as composite elements that strengthen the rod-to-base-frame connections without requiring heavy continuous reinforcing bars.
2Stability of the object's composition
If conventional reinforcing structures (reinforcing bars and connection bars) are used to prevent deformation, then structural stability is improved, but manufacturing cost increases
Solution Approach 1:
The patent segments the reinforcing function into discrete reinforcing plates positioned at specific locations rather than using continuous reinforcing bars. This segmentation reduces material usage and simplifies manufacturing, as the reinforcing plates can be independently produced and attached, lowering overall manufacturing cost while maintaining structural stability.
Solution Approach 2:
The patent extracts only the essential reinforcing function needed at critical connection points, removing the unnecessary portions of continuous reinforcing bars. This extraction approach reduces material costs and simplifies the manufacturing process by focusing reinforcement only where structurally necessary.
3Adaptability or versatility
If the base frames are designed to be convertible between folded and unfolded positions, then adaptability is improved, but structural stability deteriorates
Solution Approach 1:
The patent incorporates reinforcing plates in advance during the design and assembly process, before the bed is put into service. This preliminary reinforcement ensures that the convertible base frames maintain structural stability throughout their folding and unfolding cycles, preventing deformation that could occur with simple hinge connections alone.
Solution Approach 2:
The patent applies reinforcing plates specifically at the connection points between rods and base frames, where stress concentrates during folding and unfolding operations. This localized reinforcement maintains structural stability during the convertible operations without interfering with the foldability mechanism itself.

AI summary
A foldable bed includes first and second base frames, first and second rods fixed respectively to the first and second base frames, a first support frame mounted turnably to the first base frame, a first jack member coupled between the first rod and the first support frame for driving movement of the first support frame, and at least one reinforcing unit. The reinforcing unit includes a first reinforcing plate mounted on one of the first and second rods. When the first and second base frames are in an unfolded position, the first reinforcing plate is brought into abutting engagement with the other one of the first and second rods so as to distribute a pressure from the first jack member to the second base frame through the second rod.
