Bed Frame With Sliding Lid and Roller Tracks for Sheet Changing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed and frame devices do not efficiently facilitate the changing of sheets on a mattress, as they lack a mechanism to easily access the mattress for sheet changes while maintaining the mattress in a sleeping position.
Innovation Solution
A bed and frame device featuring a box with slidably positioned tracks and a lid that can be rolled between open and closed positions using roller units, integrated with a sliding unit and a jack for mechanical actuation, allowing the lid to be easily moved between positions for sheet changing and sleeping configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is kept in the closed position to maintain the mattress in a sleeping position, then the sleeping configuration is maintained, but access for changing sheets becomes difficult
Solution Approach 1:
The lid is designed to be dynamically movable between a closed position (for sleeping) and an open position (for sheet changing). The roller units enable the lid to slide along the tracks, transforming the static bed frame into a dynamic system that adapts to different operational needs without requiring complete disassembly or reconfiguration
2Ease of operation
If a lifting mechanism is used to raise the mattress for sheet changing, then access is improved, but the device complexity increases
Solution Approach 1:
The bed frame is segmented into a stationary box and a movable lid that can be independently positioned. This segmentation allows the lid to be separated from the box for sheet changing without requiring complex lifting mechanisms, as the lid simply slides along tracks rather than needing to be raised vertically
Solution Approach 2:
Roller units serve as intermediary elements between the lid and the box, enabling smooth lateral movement of the lid along the tracks. These rollers facilitate the sliding action without requiring complex mechanical systems, reducing overall device complexity while maintaining ease of operation
3Ease of operation
If a sliding mechanism is introduced to move the lid laterally, then ease of operation for sheet changing is improved, but the device complexity increases
Solution Approach 1:
The sliding mechanism uses simple roller units that can be easily integrated into the box structure. The rollers provide a flexible, low-complexity solution for lateral movement compared to rigid mechanical linkages or hydraulic systems, maintaining simplicity while enabling easy lid positioning
Solution Approach 2:
The sliding mechanism transforms the static lid into a dynamically positionable component that can move laterally along the tracks. This dynamic capability allows the lid to be easily accessed for sheet changing without requiring complex actuation systems, as the movement is achieved through simple rolling contact
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
Enables easy access for changing sheets by sliding the lid to a second position, while maintaining the mattress in a sleeping position when the lid is closed, enhancing usability and accessibility.
Implementation Method 1
A plurality of roller units is each disposed on the lid and rollably engages a respective one of the tracks to facilitate the lid to be rolled between the first position and the second position

AI summary
A bed and frame assembly includes a box that is positionable on a horizontal support surface. A pair of tracks is each of the tracks is removably disposed on the box. A lid is slidably disposed on the box for supporting a mattress. The lid is positionable in a first position to close the box or a second position to facilitate sheets on the mattress to be changed. A plurality of roller units is each disposed on the lid and rollably engages a respective one of the tracks to facilitate the lid to be rolled between the first position and the second position. A sliding unit is integrated into the box and the sliding unit is in mechanical communication with the lid. The sliding unit is actuatable in a closing condition for sliding the lid into the first position and the sliding unit is actuatable in an opening condition for sliding the lid into the second position.
