Sacroiliac Joint Correction Bed with Pivotable Lumbar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sacroiliac joint correction beds are limited in effectively addressing three-dimensional misalignment due to vertical dropping mechanisms, which do not adequately correct the sacroiliac joints.
Innovation Solution
A sacroiliac joint correction bed with a lumbar support system comprising four individually movable and pivotable supporting bodies, each with a holding mechanism that allows for adjustable inclination and impact force application, specifically designed to support and correct the left and right ilium and ischium areas, enabling effective corrective forces to be applied to the sacroiliac joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vertical dropping mechanism is used to apply impact force, then the structure is simple, but the correction effectiveness for three-dimensional misalignment is insufficient
Solution Approach 1:
The supporting body is designed to be pivotable around a horizontal axis, transforming from a static vertical dropping mechanism to a dynamic system that can change its orientation. This allows the supporting body to rotate from a vertical position (for impact application) to an inclined position (for support), providing adaptability that improves correction effectiveness while maintaining reasonable structural complexity
Solution Approach 2:
The invention introduces rotational movement around a horizontal axis, adding a new degree of freedom to the system. Instead of only vertical movement, the supporting body can now rotate to create inclined positions, enabling three-dimensional correction of sacroiliac joint misalignment while maintaining cost-effectiveness
2Adaptability or versatility
If multiple divided members are used to support different body parts, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The lumbar support is divided into multiple independent supporting bodies (first supporting body for ilium, second supporting body for ischium), each capable of independent movement and adjustment. This segmentation allows each component to be optimized for its specific function while maintaining overall system adaptability without excessive complexity
Solution Approach 2:
Each supporting body serves multiple functions: it provides support in an inclined position during treatment, can be rotated to a horizontal position for impact application, and can be independently adjusted for different patient conditions. This multi-functionality reduces the need for separate specialized components
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 bed provides effective correction of sacroiliac joints with an inexpensive configuration by allowing precise adjustment and application of corrective forces, improving stability and alignment while maintaining cost-effectiveness.
Implementation Method 1
configured to pivot the supporting body into a horizontal state from the inclined state when the holding member descends to the descended position by applying an impact force to the supporting body

AI summary
A sacroiliac joint correction bed provided with a lumbar support that supports a lower back, a chest support and a leg support. The lumbar support comprises four bases that respectively correspond to a left ilium, a right ilium, a left ischium, and a right ischium of the patient, and four holding mechanisms each of which exists between each of pairs of the bases and the supporting bodies, each of the holding mechanisms is provided with a main body fixed to the base and a holding member movable up and down on the main body so that the holding member takes an ascended portion and a descended position. When the holding member descends to the descended position by applying an impact force to the supporting body, two of the left supporting bodies are arranged to oppose each other, and two of the right supporting bodies are arranged to oppose each other.
