Swingable Underarm Holding Sections for Care Robot Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional care robots face difficulties in easily adjusting the underarm holding sections to align with the body of the care receiver, making it challenging to secure proper alignment.
Innovation Solution
The care robot features swingable underarm holding sections that pivot around a fulcrum point, allowing easy alignment with the care receiver's underarms by swinging the holding sections outward to create a wider arm-passing region and then inward to align with the care receiver's body position.

Engineering Contradiction Analysis
1Manufacturing precision
If slide members are used to adjust the left-right positions of underarm holding sections, then alignment with the care receiver's body is achieved, but the adjustment becomes difficult depending on the care receiver's state
Solution Approach 1:
The underarm holding sections are made swingable about fulcrum points, transforming the static slide member adjustment mechanism into a dynamic swinging mechanism. This allows the holding sections to automatically adapt to different care receiver body positions and states through natural swinging motion, eliminating the difficulty of manual slide member adjustment while maintaining precise alignment capability
Solution Approach 2:
The swingable underarm holding sections can automatically align with the care receiver's body by swinging about the fulcrum points without requiring complex manual adjustment mechanisms. The system uses the care receiver's own body position to guide the alignment process, reducing the need for operator intervention and making adjustment easier regardless of the care receiver's state

AI summary
A care robot (1) is provided with a base (10), and a pair of underarm holding sections (65a and 65b) provided on the base (10) and capable of holding the underarms of a care receiver (M1), and the care robot assists the care receiver (M1) to stand up or sit down. Further, the pair of underarm holding sections (65a and 65b) are provided to be swingable around a fulcrum (C) provided further away from the care receiver (M1) than portions (S) that hold at least the underarms of the care receiver (M1).
