Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulating bed frames are not suitable for residential use as they require a box spring assembly and cannot achieve a compact height, limiting their placement in standard residential beds.
Innovation Solution
A bed frame design featuring a lower support structure with a carriage for translational movement, an upper support structure pivotally connected to the carriage, and an actuator with a lever arm that creates lifting moments to pivot the upper body support section, allowing for a compact height and integration with standard bed frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an articulating bed frame is designed with a carriage and roller system, then the bed frame can articulate and adjust position, but the overall height cannot be reduced to a compact size suitable for standard residential beds
Solution Approach 1:
The bed frame employs a dynamic linkage system with moveable connections between the carriage, support members, and articulating sections. The support members pivotally connect to both the carriage and the articulating bed frame sections, enabling continuous adjustment of the frame's configuration and height while maintaining articulation capability.
Solution Approach 2:
The bed frame is divided into distinct modular sections: a lower support structure, a carriage, upper support structures, and articulating bed frame sections. Each segment can move independently through pivotal connections, allowing the overall height to be reduced to approximately 4.5 inches while preserving the articulation function through coordinated movement of segments.
2Strength
If the bed frame uses a traditional box spring assembly, then it provides structural support, but it increases the overall height and prevents compact integration into standard residential beds
Solution Approach 1:
The invention extracts and eliminates the traditional box spring assembly from the bed frame design. Instead, structural support is provided by the lower support structure with longitudinal members and cross members, combined with the carriage and linkage system that provides both support and articulation functions in a compact configuration achieving approximately 4.5 inches height.
Solution Approach 2:
The lower support structure with its longitudinal members and cross members serves multiple functions: providing structural support, guiding carriage movement, and enabling compact height reduction. The carriage itself performs dual functions of supporting the upper structures and enabling articulation through its moveable connections.
3Length of stationary object
If the bed frame is reduced to a compact height of about 4.5 inches, then it can be integrated into standard residential beds, but the complexity of the linkage and support system increases
Solution Approach 1:
The invention merges multiple functions into integrated components: the lower support structure combines structural support with carriage guidance; the carriage combines upper support mounting with articulation enablement; the support members combine linkage function with structural support. This merging reduces the number of separate components and simplifies the overall system while achieving compact height.
Solution Approach 2:
The bed frame employs composite construction with longitudinal members and cross members forming an integrated lower support structure. The support members act as composite linkages that simultaneously provide structural support and enable articulation movement, reducing complexity by eliminating the need for separate support and linkage components.
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 enables the bed frame to be substituted for a box spring assembly, achieving a compact height of about 4.5 inches, suitable for standard residential beds, while maintaining easy access to bedside items and securely retaining a mattress in position.
Implementation Method 1
A lever arm has a first end connected to the actuator and a second end rigidly connected to the upper body support structure adjacent where the edge thereof is pivotally connected to the seat section. The actuator and lever arm are arranged such that application of force from the actuator to the first end of the lever arm provides a motive force for moving the carriage and the upper support structure on the lower support structure while also producing a first lifting moment on the upper body support section.
Implementation Method 2
A support arm has a first end pivotally connected to the lower support structure and a second end pivotally connected to the upper body support section. The support arm is arranged such that movement of the carriage toward the head end of the lower support structure produces a second lifting moment on the upper body support section.

AI summary
A bed frame comprises a lower support structure having a head end and a foot end and a carriage arranged for translational movement on the lower support structure. An upper support structure is mounted on the carriage. The upper support structure includes a seat and an upper body support section pivotally connected thereto. A support arm is pivotally connected between the lower support structure and the upper body support section. An actuator is connected to the lower support structure. A lever arm is connected between the actuator and the carriage. Application of force from the actuator to the lever arm moves the carriage on the lower support structure while applying a lifting moment to the upper body support section. The support arm is arranged such that movement of the carriage toward the head end of the lower support structure also produces a lifting moment on the upper body support section.
