Articulated Arm Human Body Positioning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human body positioning systems, such as stationary beds and surgical tables, hinder access to various parts of the body due to their bulk and weight distribution, making it difficult to reposition patients during surgeries and other activities, and pose challenges for individuals with physical disabilities during sexual activities.
Innovation Solution
A human body positioning system utilizing a base with multiple articulated arms connected via hinges, allowing for manual or motorized movement and alignment of cutout regions to provide unobstructed access to the body, enabling efficient and safe repositioning and support of the human body in various orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stationary beds and surgical tables are used to support the human body, then the human body is stable and supported, but access to various parts of the body is hindered due to bulk and weight distribution
Solution Approach 1:
The support structure is divided into multiple articulated arms (first arm, second arm, third arm) that can be independently positioned and adjusted. Each arm can be segmented to provide access to different body parts while maintaining support functionality, resolving the contradiction between structural bulk and accessibility.
Solution Approach 2:
The support system transitions from a static bed or table to a dynamic articulated arm system with hinges and joints. This allows the structure to adapt its configuration dynamically, providing both support and unobstructed access to body parts by moving arms out of the way when needed.
2Weight of moving object
If mechanized beds reposition appendages to alter weight distribution, then weight distribution is improved, but surfaces still extend superior, inferior and lateral to the body creating obstructions
Solution Approach 1:
Instead of extending surfaces laterally and vertically around the body (traditional bed approach), the articulated arms position support points in three-dimensional space above and around the body. This dimensional repositioning allows weight distribution adjustment while maintaining clear access to all body surfaces.
3Stability of the object's composition
If retention straps are used to hold the human body, then the human body is secured, but repositioning the body becomes difficult and access is obstructed
Solution Approach 1:
The system replaces static retention straps with dynamic articulated arms that can be repositioned independently. The arms maintain body retention through adjustable positioning rather than constraining straps, allowing easy repositioning by simply moving the arms to new configurations without obstructing body access.
4Stability of the object's composition
If surgical tables are used during procedures, then the human body is supported stably, but rotation and repositioning require multiple people and risk injury
Solution Approach 1:
The support system is segmented into multiple independently controllable articulated arms rather than a single rigid table. This segmentation allows individual arms to be adjusted and repositioned separately, enabling complex body repositioning operations to be performed by a single operator through coordinated arm movements, reducing the need for multiple people and associated injury risks.

AI summary
A human body positioning system can employ a base that supports a first arm via a first hinge, a second arm connected to the first arm via a second hinge, and a third arm connected to the second arm via a third hinge. A human body may be supported within the third arm by a body support. Each of the arm can be configured with a cutout region positioned to provide physical access to a portion of the human body.
