Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding beds require multiple steps to fold, consume labor, and occupy significant space after folding, making storage and carrying inconvenient.
Innovation Solution
A folding bed design featuring a fixed support frame with hinged side support frames and transmission rods that allow simultaneous folding of bed leg support frames, eliminating the need for separate folding of second leg support frames, and incorporating U-shaped frames for safety and handling, with screw bolts for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bed leg support frames are folded separately in existing folding beds, then the folding mechanism can be simple, but the folding steps become many and labor is wasted
Solution Approach 1:
The patent combines the folding actions of multiple bed leg support frames into a single synchronized motion through the transmission rod mechanism. When one side support frame is folded, the transmission rod transmits this motion to simultaneously fold all connected second bed leg support frames, merging multiple independent folding operations into one unified action.
Solution Approach 2:
The transmission rod acts as an intermediary mechanical element that transfers and coordinates the folding motion from the side support frame to the second bed leg support frames. This intermediary mechanism enables synchronized folding without requiring complex independent control for each leg support frame.
2Ease of manufacture
If folding beds are designed with traditional folding mechanisms, then the structure can be simple, but the folded size remains big and storage is inconvenient
Solution Approach 1:
The patent implements a nested folding configuration where the second bed leg support frames are positioned to nest within or alongside the first bed leg support frames during folding. The transmission rod mechanism coordinates this nesting arrangement, allowing the folded structure to occupy minimal space while maintaining structural integrity.
Solution Approach 2:
The folding mechanism utilizes multi-dimensional space optimization by arranging the support frames to fold in coordinated directions. The transmission rod system enables the structure to collapse into a compact three-dimensional configuration that minimizes volume while maintaining ease of manufacture.
3Device complexity
If multiple folding steps are required, then the mechanism can be simple, but time is wasted during operation
Solution Approach 1:
The transmission rod mechanism ensures continuous and synchronized folding action across all bed leg support frames. As one side support frame begins to fold, the transmission rod immediately transmits this motion to all connected frames, eliminating sequential delays and ensuring all components fold simultaneously in a continuous useful action.
Solution Approach 2:
The transmission rod mechanism is pre-configured to establish mechanical connections between all bed leg support frames before folding begins. This preliminary arrangement ensures that when folding is initiated, all frames are already positioned and connected to receive the folding motion simultaneously, eliminating setup time during the actual folding operation.

AI summary
The disclosure relates to the technical field of folding beds, disclosing a folding bed, which includes a bed plate support frame and bed leg support frames disposed at lower ends of the bed plate support frame. The bed plate support frame includes a fixed support frame and side support frames, each bed leg support frame includes a first bed leg support frame and a second bed leg support frame. When the folding bed needs to be stored, the side support frames are upwards turned and folded relatively to the fixed support frame. In this process, the second bed leg support frames are driven to be turned and folded through the transmission rods, which do not need to be singly folded, so the use is convenient, and the labor is saved. After being folded, the folding bed occupies a small space, and is convenient to store and carry.
