Mattress Rotation Mechanism With Parallelogram Stable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattress adjustment mechanisms do not facilitate easy rotation of 180 degrees for changing the top and bottom surfaces, which is necessary for airing and load adjustment, and often require manual effort or complex installations, lacking a stable position for bed-making or massage functions.
Innovation Solution
A mechanism involving a lifting and rotating system with cables and discs connected to the mattress frame, actuated by winding drums on the ceiling, allows for 180-degree rotation of the mattress, incorporating a parallelogram structure with telescopic cylinders and rollers for stable positioning, and an optional anti-mite system with UV LEDs for improved sleep quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rotation of the mattress is performed, then the mattress can be rotated 180 degrees to change surfaces, but it requires significant user effort and physical strain
Solution Approach 1:
The patent replaces the manual mechanical rotation system with an automated motorized system. A motor (21) drives a drum (22) that winds a cable (20), which is attached to the mattress frame (10). This substitution eliminates the need for users to manually lift and rotate the heavy mattress, automatically performing the rotation task through mechanical automation.
Solution Approach 2:
The patent employs a counterweight system to balance the mattress weight during rotation. A counterweight (26) is connected via a cable (24) and pulley (25) system to the mattress frame (10). This counterbalancing mechanism reduces the force required to initiate and maintain mattress rotation, making the operation easier and more energy-efficient.
2Adaptability or versatility
If the mattress is rotated without a stable positioning mechanism, then rotation is possible, but the mattress cannot be securely held in the rotated position for bed-making or massage functions
Solution Approach 1:
The patent incorporates a feedback mechanism through a limit switch (30) that detects when the mattress has reached the desired rotated position. The motor (21) receives feedback from this switch to automatically stop the rotation at the correct angle, ensuring the mattress is securely positioned for bed-making or massage functions without requiring manual intervention to judge the position.
Solution Approach 2:
The patent uses an intermediary locking mechanism (29) that engages with the mattress frame (10) to secure the mattress in its rotated position. This intermediary component acts as a mediator between the motorized rotation system and the mattress, providing stable positioning and preventing unintended movement once the rotation is complete.
3Ease of operation
If complex wall-mounted rail systems are used for bed adjustment, then vertical movement is achieved, but the installation becomes complicated and requires wall attachments
Solution Approach 1:
The patent extracts the adjustment mechanism from the wall-mounted rail system and relocates it to a self-contained unit attached to the bed frame itself. The motor (21), drum (22), and cable (20) system are integrated into the bed structure, eliminating the need for complex wall installations while maintaining the bed adjustment capability. This simplifies installation by removing the requirement for wall attachments.
4Productivity
If the mattress remains in a fixed position, then the same surface is always facing up, but the mattress cannot be easily aired or have its load distribution changed
Solution Approach 1:
The patent enables the mattress to serve itself by automatically rotating to different positions. The motorized system allows the mattress to periodically flip and rotate without external intervention, facilitating air circulation and load distribution changes. This self-service capability maintains mattress hygiene and comfort by automatically performing maintenance functions that would otherwise require manual effort.

AI summary
The invention relates to a method and to a mechanism for adjusting mattresses or chair beds into an operating position. The mechanism comprises extendable guides or telescopic cylinders or drives (6 and 7), in which rods (8 and 9) run, which merge in a joint pin (10), which interacts indirectly or directly with pins of a mattress, which protrude from a center line of the mattress. According to the invention, a parallelogram has joints (22 and 10), which are connected to each other through an elongated-hole guide (41), with one joint (22) that can be moved in the elongated-hole guide (41), wherein the rods (8 and 9) are articulated to the joint pin (10), a bushing (44) being arranged therebetween, wherein the pin (10) extends into a pulley having a restoring spring (43) from one side, on which pulley a cable (42) is wound, which cable is fastened at a free end thereof to the joint (22), wherein, at a certain height of the mattress, that is, at a certain angle between the two rods (8 and 9), the cable (42) is tensioned and the angle is reduced further, wherein the cable causes the rotation of the pulley (43) in such a way that the mattress itself is rotated.
