Height-Adjustable Bed Assembly With Longitudinal Sliding Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motorhomes or caravans, vertically sliding beds often obstruct passage to toilet or storage areas when lowered, making user movement difficult due to their cumbersome position.
Innovation Solution
A height-adjustable bed assembly with a support that slides vertically between a rear storage position and a front position, equipped with a lifting mechanism, flexible suspension links, and a device to detect the bed's storage position, allowing the bed to be lifted and slid longitudinally to free up space, with a motor for controlling the vertical position and guide rails for smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bed is lowered into the position of use, then the bed can be used for sleeping, but it blocks the passage of users to toilet area or storage area
Solution Approach 1:
The bed structure is divided into two independent sliding components: the support slides vertically along fixed vertical slides, while the bed base slides longitudinally along the support. This segmentation allows the bed to be positioned in multiple configurations - when the bed base is slid forward along the support, it clears the passage area while maintaining usability
Solution Approach 2:
The bed assembly incorporates dual sliding mechanisms that enable dynamic repositioning. The support can slide vertically between retracted and lowered positions, and the bed base can slide longitudinally between rear storage position and front position. This dynamic capability allows users to adjust the bed configuration to either maximize passage area or optimize sleeping space as needed
2Area of stationary object
If the bed base is positioned at the rear for storage, then space is freed in the cockpit area, but the bed cannot be used
Solution Approach 1:
The longitudinal sliding mechanism allows the bed base to be dynamically repositioned from the rear storage position to the front position. When the bed base is at the rear, the cockpit area is maximized; when sliding to the front, the bed becomes usable. This dynamic repositioning resolves the contradiction between storage space and usability
3Area of stationary object
If a vertically sliding bed is used, then living space is freed when retracted, but the bed becomes cumbersome and blocks passage when lowered
Solution Approach 1:
The bed system is segmented into the support (which slides vertically) and the bed base (which slides longitudinally on the support). This allows independent control of vertical retraction for living space and longitudinal positioning for passage clearance, resolving the contradiction between living space and user movement
Solution Approach 2:
The invention adds a longitudinal sliding dimension to the traditional vertical sliding bed. The bed base can slide along the length of the support, providing an additional degree of freedom. This dimensional addition allows the bed to clear passage areas horizontally while maintaining vertical retraction capability for living space optimization
