Modular Folding Bed with Console Supports for Stable Wide Double Beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding bed systems require robust body components to handle high forces and torques, necessitating complex assembly and transport, and cannot be designed as stable double beds with a width over 160 cm without a wide central gap, or without visible swivel fittings.
Innovation Solution
A modular folding bed system with self-supporting console supports between the bed frame's longitudinal beams, eliminating the need for solid side walls and allowing compact, cost-effective swivel fittings, and incorporating gas pressure springs for ease of pivoting and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If robust body components are used to handle high forces and torques, then mechanical stability is improved, but assembly and transport complexity increases
Solution Approach 1:
The base frame is divided into modular components: side panels, console supports, and cross members that can be separately manufactured and assembled. This segmentation allows each component to be optimized for its specific function while simplifying overall assembly and transport operations.
Solution Approach 2:
The swivel fittings are extracted from the body side walls and repositioned to be supported by console supports that extend between the longitudinal beams. This extraction eliminates the need for robust body components to handle swivel forces, thereby reducing assembly and transport complexity while maintaining mechanical stability.
2Stability of the object's composition
If solid side walls extending above pivot fittings are used, then structural stability is improved, but a wide central gap is created disrupting sleeping comfort
Solution Approach 1:
The side walls are extracted from their traditional position above the pivot fittings and repositioned to extend only up to the level of the longitudinal beams. The pivot fittings are simultaneously extracted from the side walls and repositioned to be supported by console supports. This dual extraction eliminates the wide central gap while maintaining structural stability through the console support mechanism.
Solution Approach 2:
The support structure for pivot fittings transitions from a vertical dimension (side walls extending above pivot points) to a horizontal dimension (console supports extending between longitudinal beams). This dimensional change allows the side walls to be lower, eliminating the central gap while maintaining stability through the horizontal console support structure.
3Ease of operation
If swivel fittings are supported by body side walls, then pivot function is achieved, but visible fittings and complex body construction are required
Solution Approach 1:
The swivel fittings are extracted from the body side walls and repositioned to be supported by console supports that extend between the longitudinal beams. This extraction achieves two objectives: the pivot function is maintained while the fittings become invisible when the bed frame is swung out, and the body construction is simplified as it no longer needs to provide structural support for the swivel mechanism.
Solution Approach 2:
Console supports are introduced as intermediary elements between the longitudinal beams and the swivel fittings. These console supports serve as the new support structure for the pivot fittings, eliminating the need for the body side walls to provide this function. This intermediary structure simplifies body construction while maintaining pivot functionality and achieving invisible fittings.
4Ease of operation
If bed frame width is increased to over 160 cm, then sleeping comfort is improved, but deflection and noise problems occur
Solution Approach 1:
The base frame is segmented into multiple support elements: side panels, console supports, and cross members. This segmentation distributes the load across multiple points rather than relying on a single continuous structure, reducing deflection and noise while allowing the bed frame to span wider distances for improved sleeping comfort.
Solution Approach 2:
The console supports extend beyond the minimum required length to provide adequate support for the swivel fittings and distribute loads effectively. This excessive action ensures that even with bed frame widths over 160 cm, the structure maintains sufficient rigidity to prevent deflection and noise while accommodating the wider sleeping surface.
