Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding beds face challenges in simplifying the usage and folding process while reducing weight, as existing designs often require complex assembly and heavy materials.
Innovation Solution
An easy-assembling folding bed design featuring a bed surface, side rods, and a footing component with C-shaped engaging pieces, L-shaped supporting rods, and a reset torsional spring mechanism that allows for simple assembly and disassembly by adjusting the distance between engaging pieces using a lever principle and automatic locking/unlocking with a locking hook and spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional folding bed designs are used, then the bed can be folded and retracted for space saving, but the assembly and folding process becomes complex and time-consuming
Solution Approach 1:
The bed frame is divided into multiple detachable components including footing components, bed side rods, and connecting components. Each footing component can be independently assembled and disassembled from the bed side rods through simple insertion and locking actions, avoiding complex folding mechanisms while achieving easy assembly and disassembly.
2Ease of operation
If traditional folding bed designs are used, then the bed can be folded for portability, but the weight increases due to heavy materials and complex structure
Solution Approach 1:
The bed is segmented into multiple lightweight components that can be separately carried and assembled. The footing components and bed side rods are designed as separate detachable parts, allowing users to carry only necessary components and assemble them at the destination, reducing overall transport weight while maintaining portability.
Solution Approach 2:
The complex folding mechanism and heavy support structures are extracted and replaced with simple detachable footing components that lock into the bed side rods. This extraction of unnecessary complexity significantly reduces the weight while maintaining the bed's structural integrity and portability.
3Ease of manufacture
If simple connecting structures are used, then the bed is easier to assemble, but the stability and strength of the bed surface decreases
Solution Approach 1:
The footing components are pre-designed with C-shaped engaging pieces that automatically engage with the bed side rods upon insertion. The locking pieces are pre-positioned to automatically lock when the footing components are inserted, providing strong stable connections without requiring complex assembly procedures or tools.
Solution Approach 2:
The footing components feature self-locking mechanisms where the locking pieces automatically engage with the bed side rods when the footing components are inserted. This self-service locking mechanism ensures strong stable connections while maintaining assembly simplicity, as the structure secures itself without additional fastening steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design results in a lightweight, easy-to-carry folding bed with a simple structure that can be quickly assembled and disassembled, reducing packaging volume through a straightforward mechanism that tightens and locks the bed surface using a torsional spring and lever system.
Implementation Method 1
a reset torsional spring; the top of the second C-shaped engaging piece is hinged to the end of the second L-shaped supporting rod, and the bottom thereof is hinged with the locking hook by the reset torsional spring
Implementation Method 2
under the torsion of the reset torsional spring
Implementation Method 3
the first L-shaped supporting rod and the opposite end of the second L-shaped supporting rod are connected via an elastic cord

AI summary
Disclosed is an easy-assembling folding bed, comprising a bed surface, bed side rods, and a footing component; the rods are disposed in parallel, the footing component is arranged in multiple groups, uniformly disposed and is engaged with the rods; the footing component comprises first and second components. The invention has simple structure, less materials, lighter weight and is convenient to carry. By rotating the second C-shaped engaging piece, the distance between the first and second C-shaped engaging pieces is changed, so the surface is tightened. The locking hook can automatically hook the locking fixing piece and lock it by the reset torsional spring, so the consumer can tighten and lock the surface. By twisting the hook to overcome the torsion of the spring and then rotating, the hook and the fixing piece are disengaged, and the footing component can be easily removed and folded to reduce the packaging volume.
