Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bed frames are either lightweight and limited in functionality or heavy and complex, lacking a balance between simplicity, strength, and ease of use.
Innovation Solution
An adjustable bed frame design featuring structures with mounting units, leg units, support units, and driving units that allow for simple, strong, and easy adjustment between leveled and tilted positions, using sloped surfaces and motorized rotation mechanisms to stabilize and retain support units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If hollow steel or plastic tubes are used for bed frame construction, then the bed frame becomes lightweight, but the strength and functional area are reduced
Solution Approach 1:
The bed frame combines wood and metal materials to create a composite structure. The wooden support units provide strength and stability, while the metal leg units provide durability and structural support. This composite approach allows the bed frame to achieve both light weight and high strength, resolving the contradiction between these two parameters.
2Ease of operation
If motors are added to enable bed frame adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex motorized adjustment mechanisms with a simpler mechanical system. The support units can be manually adjusted between different positions (first position for sleeping, second position for sitting) using a mechanical linkage system with pivoting connections. This substitution maintains ease of operation while significantly reducing device complexity.
3Adaptability or versatility
If multiple segments are used in support units, then adaptability and positioning flexibility are improved, but device complexity increases
Solution Approach 1:
The support units are divided into multiple segments that can pivot relative to each other, allowing the bed frame to assume different configurations (sleeping position, sitting position, etc.). This segmentation provides adaptability and positioning flexibility while maintaining relatively simple construction through the use of pivoting connections between segments.
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 provides a stable, easy-to-use bed frame that can be adjusted to various positions, offering improved comfort and support, while maintaining structural integrity and ease of operation.
Implementation Method 1
The first driving unit is configured to rotate the first segment of the first support unit with respect to the mounting unit. Rotation of the first segment then causes the third segment to move along the first sloped surface of the first leg unit
Implementation Method 2
The third segment has an upper portion fixedly coupled or integrally formed with the second segment and a lower portion abutting the first sloped surface of the first leg unit. Abutting of the third segment on the first sloped surface of the first leg unit defines, at least in part, a slope of the second segment

AI summary
An adjustable bed frame includes one or more structures, each having a mounting unit, a leg unit, a support unit and a driving unit. The leg unit includes a sloped surface. The support unit comprises first, second and third segments. The first segment is rotatable relative to the mounting unit by the first driving unit. The second segment is pivotally coupled with the first segment. The third segment has an upper portion fixed with the second segment and a lower portion abutting the sloped surface of the leg unit. As the first segment rotates relative to the mounting unit, the third segment moves along the sloped surface of the leg unit. By abutting on the sloped surface of the leg unit, the third segment defines, at least in part, a slope of the second segment, and helps to retain the support unit in position.
