Eccentric Transverse Beam Bed Support for Adjustable Orthopaedics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed systems fail to adapt orthopaedic support to changes in the human body over time, with previous solutions offering limited and cumbersome height adjustments that can lead to incorrect or unstable installations.
Innovation Solution
A mattress supporting system with a height adjustment system featuring rotatable transverse beams having an eccentric rotation axis, accessible from outside the frame, allowing for limited and precise height adjustments without disassembling the structure, and a blocking mechanism to prevent unintended position changes under dynamic loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If height differences are built in the mattress structure in a fixed manner, then orthopaedic support for different body parts is improved, but the bed system cannot be adapted to changes in the human body over time
Solution Approach 1:
The patent applies the dynamics principle by making the mattress supporting structure adjustable rather than fixed. The height of the supporting structure can be dynamically changed to adapt to different body profiles over time, while still providing reliable orthopaedic support through controlled positioning mechanisms
2Adaptability or versatility
If a limited area of the mattress supporting structure is adjusted, then height customization is achieved, but the adjustment process becomes cumbersome and requires multiple steps
Solution Approach 1:
The patent merges the adjustment mechanism into the overall mattress supporting structure, allowing for coordinated adjustment of multiple areas simultaneously. This integration reduces the number of separate adjustment steps required while maintaining the ability to customize height for different body regions
3Adaptability or versatility
If the left and right side of the bed are separately installed, then height adjustment is possible, but incorrect installation and unstable supporting structure are likely
Solution Approach 1:
The patent designs a universal adjustment mechanism that functions identically on both left and right sides of the bed. This standardized multi-functional design ensures consistent installation procedures and reduces the risk of incorrect assembly, thereby improving overall structural stability
4Adaptability or versatility
If triangular rotation means are used for height adjustment, then three different height levels are provided, but the contact surface is too small to provide stable support
Solution Approach 1:
The patent transitions from small contact surface rotation means to a broader base supporting structure. By expanding the contact area in the horizontal dimension while maintaining vertical height adjustment capability, the system achieves both height variability and stable support
5Reliability
If additional slats are added on top of rotation means to support springs, then support is provided, but the height of the mattress supporting system is adversely increased
Solution Approach 1:
The patent integrates the spring support function directly into the rotation means structure itself, rather than adding separate slats on top. This nested design allows the springs to be supported by the rotated structure, eliminating additional height while maintaining support capability
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
The system provides stable and customizable orthopaedic support by allowing users to adjust the height of specific areas with minimal risk of incorrect installation, ensuring optimal support for varying body parts over time while maintaining structural stability.
