Segmented Recliner Bed With Pivot Supports for Natural Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recliner devices restrict natural movement and posture, leading to muscle tensions, spine malpositions, and discomfort, particularly for individuals with weakened muscle tone or those requiring physiotherapy, as they often fix the lying or sitting position and do not allow for free torsional movement between the chest and pelvis.
Innovation Solution
A recliner device with independently movable thigh and back/head supports, each equipped with pivot bearing devices that allow for horizontal axis rotation, enabling the person to recline in a natural posture, promoting balance and muscle tone through free movement along the spinal axis, and incorporating lever arms for adjustable support and micro-movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional recliner devices are used with fixed planar construction, then structural stability is improved, but natural movement freedom and posture adaptability deteriorate
Solution Approach 1:
The recliner device is divided into multiple independent support modules: a first thigh support, a second thigh support, and a back support, each capable of independent movement. This segmentation allows each module to adapt to different body positions while maintaining overall structural stability through their coordinated arrangement.
Solution Approach 2:
The patent implements dynamic capabilities by equipping each support module with pivot bearing devices that enable free rotation around horizontal axes. The thigh supports can pivot independently, and the back support can rotate freely, allowing the structure to adapt dynamically to natural body movements and postures while maintaining stability through controlled degrees of freedom.
2Device complexity
If fixed posture support is provided, then structural simplicity is improved, but muscle tone development and balance exercise deteriorate
Solution Approach 1:
The device maintains relative structural simplicity while enabling balance exercises through strategic placement of pivot mechanisms. The thigh supports pivot around horizontal axes at defined locations, and the back support rotates around a horizontal axis, creating controlled degrees of freedom that require active muscle engagement for stabilization without requiring complex control systems.
Solution Approach 2:
The recliner device enables users to perform balance exercises and muscle tone development independently without requiring external assistance or complex control mechanisms. The free rotation capabilities and pivot bearing devices allow users to spontaneously adjust their posture and engage in therapeutic exercises on their own initiative.
3Adaptability or versatility
If independent movable thigh supports and back support are provided, then natural movement freedom is improved, but device complexity increases
Solution Approach 1:
The device achieves movement freedom through segmentation into independent support modules, each with its own pivot mechanism. The first thigh support, second thigh support, and back support are independently mounted and can move freely within their respective degrees of freedom, allowing natural body movements without requiring a fully complex integrated system.

AI summary
The invention relates to a recliner device for supporting a lying person, the recliner device having a foot and arranged thereon (i) a first movably mounted thigh support for supporting the first thigh of the person, (ii) a movably mounted second thigh support for supporting the second thigh of the person, the second thigh support being independent of the first thigh support and being combinable with the first thigh support to form a complete support, and (iii) a movably mounted back and head support that is independent of the first and second thigh supports.
