Pivoting Mattress Assembly for Bed Entry and Exit in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed systems require large spaces and are not very flexible in operation, making them cumbersome and difficult to use in tight spaces.
Innovation Solution
A bed system with a mattress assembly pivotably mounted on a bed frame, controlled by a controller device that allows the mattress to pivot between 30 to 80 degrees and tilt the leg part at least 45 degrees, enabling flexible positioning and operation in limited spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mattress assembly is made pivotable to improve flexibility and ease of operation, then ease of operation is improved, but device complexity increases due to additional mounting mechanisms and control systems
Solution Approach 1:
The mattress assembly is made dynamically pivotable relative to the bed frame, transitioning from a static to a dynamic configuration. This allows the mattress to rotate about a pivot axis between 30-80 degrees, enabling flexible positioning for easier entry and exit while maintaining structural integrity through controlled mechanical joints
2Ease of operation
If the leg part is tilted at large angles to facilitate entry and exit, then ease of operation is improved, but stability of the bed structure deteriorates
Solution Approach 1:
The leg part is designed with dynamic tilting capability, allowing it to rotate relative to the seat part through controlled angular ranges. This enables the leg to be tilted forward at least 45 degrees to create a ramp-like surface for easier entry, while the mechanical joint constraints maintain structural stability during operation
3Adaptability or versatility
If the pivot angle is increased to expand positioning options, then adaptability is improved, but the space required for operation increases
Solution Approach 1:
The bed system utilizes rotational movement about a vertical pivot axis to achieve positioning in a different dimensional space. By pivoting the mattress assembly between 30-80 degrees, the system expands its positioning capabilities without requiring additional floor space, as the adjustment occurs through angular displacement rather than linear extension
