Bed Frame with Interchangeable Spacers for Constant Mattress Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed frames do not allow for adjustable mattress height, limiting compatibility with different mattress thicknesses and requiring a specific mattress choice that may not be compatible with the bed design or future replacements, affecting both manufacturers and consumers.
Innovation Solution
A bed frame design featuring interchangeable spacer members and a modular structure with transverse box-shaped elements and longitudinal bars, allowing for adjustable height to accommodate mattresses of varying thickness while maintaining a constant upper surface height, suitable for single, queen, and double beds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bed frame uses a fixed structure with rigid perimeter walls, then the structural stability and aesthetic design are maintained, but the mattress height cannot be adjusted for different mattress thicknesses
Solution Approach 1:
The bed frame is divided into modular components: a fixed structural frame and interchangeable spacer members. The spacers are segmented elements that can be removed and replaced to adjust the bed base height, allowing adaptation to different mattress thicknesses without modifying the main frame structure.
Solution Approach 2:
The bed frame transitions from a completely fixed structure to a dynamically adjustable system. The spacer members can be interchanged to change the height configuration, enabling the frame to adapt to different mattress thicknesses while maintaining structural integrity through the fixed frame components.
2Manufacturing precision
If the bed frame is designed with fixed perimeter walls at a specific height, then the aesthetic balance and structural integrity are preserved, but the upper surface height cannot remain constant when mattress thickness varies
Solution Approach 1:
The height adjustment function is segmented into separate spacer members rather than being integrated into the main frame. This allows the frame to be manufactured with fixed, precise dimensions while the spacers provide the variable height compensation needed to maintain a constant upper surface height.
Solution Approach 2:
The spacer members act as intermediary elements between the fixed frame structure and the mattress. These spacers absorb the height variation caused by different mattress thicknesses, allowing the frame to remain simple and easy to manufacture while still achieving precise height control.
3Adaptability or versatility
If the bed frame uses fixed feet at a predetermined height, then the overall frame stability is ensured, but the bed base height cannot be adjusted to accommodate different mattress thicknesses
Solution Approach 1:
The height adjustment capability is segmented into removable spacer members that can be independently installed or removed. This segmentation allows customers to easily assemble and reconfigure the bed base height without complex tools or procedures, maintaining ease of operation while providing adaptability.
Solution Approach 2:
The interchangeable spacer members are designed to be easily installed and removed by the customer without requiring specialized tools or technical expertise. This self-service design enables users to independently adjust the bed base height to match different mattress thicknesses.

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.
