Slatted Bed Frame Hardness Adjustment With Anti-Shift Slat Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hardness adjustment devices for three-slat arrangements in slatted frames tend to shift over time, leading to a loss of customized spring elasticity and lying comfort, as they are not adequately fixed in position during long-term use.
Innovation Solution
The solution involves enhancing the positional fixation of the hardness adjustment device by increasing frictional forces between the upper slats and the holding area through the use of separate slat holders with side walls and prestressing means, which generate high frictional forces when the holding bracket is in the closed position, preventing unintended movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hardness adjustment device is designed as a simple slide without additional fixation mechanisms, then the device complexity is reduced and ease of operation is improved, but the positional stability deteriorates and the device automatically shifts along the three-slat arrangement over time
Solution Approach 1:
The holding bracket is pre-configured with a closed position that automatically engages with the upper slats when the hardness adjustment device is placed in the receiving chamber. This preliminary positioning action occurs before use, ensuring the device remains fixed at the selected position without requiring additional fixation steps during operation.
Solution Approach 2:
The holding bracket serves as an intermediary element between the hardness adjustment device and the upper slats. It mediates the connection by providing a closed-position latch mechanism that secures the device against the slats, preventing automatic shifting while maintaining ease of adjustment when opened.
2Stability of the object's composition
If the holding bracket is designed to fully enclose the upper slats in the closed position, then the positional fixation is improved and automatic shifting is prevented, but the ease of installation and removal deteriorates
Solution Approach 1:
The holding bracket is designed with dynamic functionality, allowing it to switch between an open position for easy installation/removal and a closed position for secure fixation. This dynamic state change enables the same structure to fulfill both contradictory requirements at different operational stages.
Solution Approach 2:
The closed position of the holding bracket is pre-configured to automatically engage with the upper slats upon insertion, providing immediate fixation without requiring additional manual adjustment or complex assembly steps, thus maintaining ease of installation while ensuring positional stability.
3Adaptability or versatility
If the hardness adjustment device allows free movement along the three-slat arrangement, then the adaptability is improved and spring elasticity can be adjusted, but the reliability deteriorates and the device shifts automatically during long-term use
Solution Approach 1:
The holding bracket is pre-configured to automatically latch into the closed position when the hardness adjustment device is placed at the desired location. This preliminary fixation action occurs immediately after positioning, preventing any subsequent automatic shifting during long-term use while preserving the ability to adjust spring elasticity by selecting different positions.
Solution Approach 2:
The holding bracket acts as an intermediary that temporarily restrains the hardness adjustment device at the selected position. It provides reliable long-term positioning by mediating between the need for adjustability and the need for stability, allowing movement only when intentionally repositioned.

AI summary
The present invention relates to a hardness adjustment device (1) for a three-slat arrangement (2) of a slatted frame for a bed, having a holding area (5) and a supporting area (6), the holding area (5) having at least one receptacle (7) through which at least one upper slat (3) extends through it, and has at least one retaining clip (8) for fixing the hardness adjustment device (1) to the three slat arrangement (2), which is between a closed position (SS) in which it holds at least one of the upper slats ( 3) overlaps and closes the respective receiving chamber (7), and an open position (OS) can be adjusted in which it opens the respective receiving chamber (7) along its circumference so that it is accessible through a circumferential opening (11), and wherein the respective retaining bracket (8) is secured in the closed position by means of a latching device (13). The function is improved if the holding area (5) for the two upper slats (3) each has a slat receptacle (14) with two side walls (15, 16) for lateral positioning of the respective upper slat (3) and with a floor (17 ) for placing the respective upper slat (3), and if prestressing means (18) are provided which generate a prestress in the closed position (SS) of the respective retaining bracket (8), which at least one of the side walls (15, 16) laterally brings a longitudinal edge (19, 20) of the respective upper slat (3) into contact under pretension.
