Bed Frame with Interchangeable Spacers for Mattress Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed frames do not allow for adjustable mattress height, necessitating a specific mattress choice to match the bed's design, limiting flexibility in mattress replacement and aesthetic compatibility with other furniture.
Innovation Solution
A bed frame with interchangeable spacer members, such as metal tubing spars, that adjust the height of the bed base to accommodate mattresses of varying thicknesses, ensuring a constant upper surface height regardless of mattress thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bed frame uses a fixed structure without adjustable components, then the manufacturing and assembly are simple, but the mattress height cannot be adjusted to accommodate different mattress thicknesses
Solution Approach 1:
The bed frame is divided into modular components: a fixed headboard assembly, a removable bed base, and interchangeable spacer members. This segmentation allows the spacer members to be replaced to adjust mattress height while keeping the main frame structure simple and unchanged.
Solution Approach 2:
The spacer members serve multiple functions: they provide structural support for the bed base, determine the height of the mattress above the ground, and enable adjustment for different mattress thicknesses. This multi-functionality allows a single component to address multiple requirements without increasing overall system complexity.
2Adaptability or versatility
If the bed frame is designed with a specific mattress height requirement, then the aesthetic balance with furniture is maintained, but the customer is constrained in mattress replacement choices
Solution Approach 1:
The bed frame incorporates adjustable spacer members that can be removed and replaced to change the bed base height. This dynamic adjustment capability allows the mattress height to be modified while maintaining the aesthetic balance established by the headboard and footboard designs, as the overall frame structure remains unchanged.
Solution Approach 2:
The spacer members come in different height specifications, allowing customers to change the vertical parameter of the bed base to match different mattress thicknesses. This parameter adjustment enables mattress replacement flexibility while preserving the aesthetic proportions of the bed frame relative to other furniture pieces.
3Ease of operation
If the bed base height is fixed relative to the ground, then the structural design is simple, but the upper side of the mattress cannot maintain a constant height when mattress thickness varies
Solution Approach 1:
The spacer members act as intermediary elements positioned between the bed base and the ground. By adjusting the height of these spacers, the mattress height above the ground can be maintained at a constant level even when mattress thickness varies, without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The appropriate spacer members are selected and installed in advance based on the mattress thickness before the bed is assembled. This preliminary action ensures that the mattress will be at the correct height from the ground, eliminating the need for complex adjustments after assembly and maintaining ease of operation.

AI summary
The bed frame (100) comprises a first and a second transverse element (1, 2), made of metal having a box shape, respectively arranged close to the headboard (10) and the front head (11) of the bed (L), mutually connected by a pair of longitudinal elements (6). Said first and second transverse elements (1, 2) support bed joineries (8, 9), arranged inside the aforementioned longitudinal elements (6), suitable to act as spacers to support a bed base (12) on which the mattress (M) of the bed (L) itself is placed. By appropriately calibrating the height of the bed joineries (8, 9), which are interchangeable, according to the greater or lesser thickness of the mattress (M), it is obtained that the height from the ground of the upper horizontal side (20) of the latter, as well as its protrusion with respect to the upper edges of the longitudinal elements 6, are almost constant.
