Assisting Device Dual Handle Segmentation for Tilting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assisting devices for care receivers, while providing tiltable chest pads for improved posture adjustment, lack optimal layouts for grips and handles, affecting usability and stability during standing and sitting operations.
Innovation Solution
An assisting device with a movable base, raising and lowering mechanism, oscillating member, and a freely tiltable holding member, featuring separate first and second handles, where the first handle is fixed and the second handle is integrated with the holding member for stable movement and safe tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holding member is made freely tiltable to allow posture adjustment, then the care receiver's comfort and natural movement are improved, but the layout and positioning of handles becomes difficult to optimize
Solution Approach 1:
The patent divides the handle system into two separate components: a first handle fixed to the oscillating member and a second handle fixed to the holding member. This segmentation allows the holding member to tilt freely for posture adjustment while the first handle remains stable for caregiver operation, resolving the conflict between comfort and handle positioning.
2Ease of operation
If the holding member tilts freely to improve usability, then natural standing and sitting movements are enabled, but the stability of movement operation by caregivers deteriorates
Solution Approach 1:
By separating the handle into two independent parts attached to different movable components, the patent enables differential movement: the second handle moves with the tilting holding member for usability, while the first handle remains stable relative to the oscillating member for movement stability.
Solution Approach 2:
The patent implements a dynamic handle system where different parts of the handle can move independently according to their attachment points. The first handle provides stable reference for caregiver control, while the second handle adapts to the tilting holding member, creating a dynamically adaptive interface.
3Device complexity
If a single integrated handle is used, then the structure is simple, but the relative position between the handle and holding member changes during tilting, reducing safety
Solution Approach 1:
The patent segments the handle into two distinct parts attached to different components. This ensures that the second handle maintains a constant relative position to the holding member during tilting, preventing positional shifts that could compromise safety while keeping the overall structure manageable.

AI summary
An assisting device provide with: a movable base on which a care receiver rides; a raising and lowering member supported on the base to be movable in an up-down direction; a raising and lowering drive section configured to drive the raising and lowering member up and down; an oscillating member supported on the raising and lowering member to be capable of oscillating; an oscillating drive section configured to drive the oscillating of the oscillating member; a holding member supported on the oscillating member to be freely tiltable, and configured to hold an upper body of the care receiver; a first handle provided on the oscillating member; and a second handle provided on the holding member, and configured to tilt together with the holding member. Accordingly, practicality is improved with regard to safe moving operation of the assisting device and safe free tilting of the holding member.
