Bed Base Suspension Stop With Adjustable Compression Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for mattresses are complex in design and lack easy adjustment of the reception stroke, making them difficult to simplify and customize.
Innovation Solution
A suspension device with a movable stud abutment that can interlock with the base, featuring multiple contact zones of different lengths, allowing for adjustable reception strokes and enhanced damping levels through elastic deformation, enabling easy adjustment and customization of the device's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suspension device uses a fixed abutment design, then the structure is simple, but the reception stroke cannot be adjusted
Solution Approach 1:
The abutment is designed with a movable active part (stud) that can rotate about its longitudinal axis, transforming a static structure into a dynamic one. This rotation allows the active part to engage with different contact zones on the damping element, thereby adjusting the reception stroke length while maintaining a relatively simple overall structure.
Solution Approach 2:
The solution adds rotational freedom in the angular dimension around the longitudinal axis of the stud. By rotating the active part to different angular positions, different contact zones are engaged, enabling adjustment of the reception stroke without adding complex linear displacement mechanisms.
2Adaptability or versatility
If the suspension device allows easy adjustment of reception stroke, then the device is more versatile, but the design becomes more complex
Solution Approach 1:
The movable active part of the abutment can rotate about its longitudinal axis to engage different contact zones, enabling adjustment of the reception stroke. This dynamic element is integrated into the existing structure, allowing customization without substantially increasing overall device complexity.
Solution Approach 2:
The damping element is designed with multiple contact zones on its surface, creating a composite structure that combines the damping function with the adjustment function. This integrated design allows the same component to serve multiple purposes, reducing the need for additional separate adjustment mechanisms.

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 solution simplifies the architecture of the suspension device, allowing for easy adjustment of the reception stroke and increased damping levels, providing a more versatile and customizable solution for mattress support.
Implementation Method 1
a damping element connecting the plate to the base, this damping element being capable of moving from a so-called rest position in which the plate is separated from the fixing base in a damping position in which the damping element is compressed
Implementation Method 2
The stop 6 arranged between plate 3 and base 2 in rest position of the damping element 5 takes the form of a stud with a longitudinal axis XX′ substantially parallel to the direction D of movement of the plate 3... This elastic stop is deformable in the direction of a crushing in the bearing contact position

AI summary
Device (1) that can be interposed between a support structure and a mattress and comprising: - a base (2) for fixing the device (1) to the support structure, - a support plate (3) for the mattress, - an element (5 ) damper connecting the plate (3) to the base (2) and compressible in the direction of bringing the plate (3) closer to the base (2), -a stop (6) arranged on the path followed by the plate ( 3) and/or the damping element (5) during compression. The stop (6) is mounted to move between two positions, and has in each position a zone (8) of contact with which the plate (3) and/or the damping element (5) are configured to come into abutment in the so-called position end of home race, said contact zones (8) corresponding, one, to a first home race, the other to a home race of different length from the first race.
