Bed frame for convenient changing of bed sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bed frames in hotels and guest houses require laborious and time-consuming processes for changing bed sheets, as staff need to pull out the bed and maneuver around the bed liner to insert new sheets, due to the mass and design of the bed and mattress.
Innovation Solution
A bed frame design incorporating a sliding module and rotation device allows the bed sheet to be changed by sliding the module out and rotating it through a dedicated mechanism, enabling staff to insert the sheet without walking around the frame, reducing effort and time through low-friction slide rails and universal ball components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bed and mattress are made with large mass for stability and comfort, then the bed structure is stable and comfortable, but the process of pulling the bed out and changing bed sheets becomes more laborious and time-consuming
Solution Approach 1:
The bed structure is segmented into a stationary base and a movable bed assembly (mattress + bed frame). The movable bed assembly can be easily pulled out and pushed back independently from the heavy stationary base, reducing the effort required for bed sheet changing while maintaining the stability of the overall bed structure through the stationary base.
2Stability of the object's composition
If the bed frame is designed with a fixed structure for simplicity and stability, then the structure is stable and easy to manufacture, but the staff need to walk around the bed frame to insert bed sheets, which is time-consuming and labor-intensive
Solution Approach 1:
The bed frame incorporates a movable bed assembly that can be dynamically adjusted. The staff can pull the movable bed assembly outward to create access space, insert bed sheets efficiently, and then push it back into position. This dynamic movement capability resolves the contradiction by maintaining structural stability of the overall frame while enabling time-efficient bed sheet changing operations.
3Ease of operation
If the bed frame uses a drawer-type sliding device for moving the bed liner, then the bed liner can be easily pulled out, but the staff still need to walk around the bed liner to completely insert the bed sheet, which remains time-consuming and labor-intensive
Solution Approach 1:
The bed structure is divided into a stationary base with sliding mechanism and a movable bed assembly. The sliding mechanism is integrated into the base rather than requiring complex drawer-type devices for the entire bed. This segmentation allows the bed assembly to be easily moved for sheet changing while keeping the sliding mechanism simple and integrated, reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables staff to change bed sheets efficiently from a single position, saving energy and time, while also extending the life of the mattress by rotating it 180 degrees during changes.
Implementation Method 1
the slide rail and the sliding block are matched not only with low friction resistance
Implementation Method 2
the sliding part is able to be embedded and roll in the slide slot

AI summary
A bed frame convenient for changing bed sheets includes a base, a rotation module for accommodating a mattress located above the base ,a sliding module located between the rotation module and the base ,a sliding device located between the sliding module and the base , wherein the sliding module is able to slide along a length of the base through the sliding device, and a rotation device located between the sliding module and the rotation module, wherein the rotation module is able to rotate around a central axis of the sliding module through the rotation device. Through the cooperation of the sliding device and the rotation device, a staff is able to change the bed sheet only by standing in one position, which greatly saves energy and time of the staff. After changing the bed sheet every time, the mattress is rotated exactly 180 degrees, which is able to extend the life of the mattress.
