Standing Aid Loop Handles Prevent Slipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raising aids pose a risk of the person requiring help slipping out during the standing process due to the non-slip surface, leading to unfavorable strain on both the helper and the person, potentially resulting in falls.
Innovation Solution
The raising aid features a holding belt with length-adjustable pull handles that form a loop, allowing for secure grip and reduced slipping by being fixed on one end to the belt and sliding through guides, with additional fixed handles providing additional support and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-slip surface is used on the holding belt to prevent slipping, then the grip security is improved, but the risk of the entire raising aid slipping uncontrollably on the person's back increases
Solution Approach 1:
The raising aid is divided into two distinct functional components: a holding belt with non-slip surface for secure grip, and separate loop structures that prevent uncontrollable slipping. The loop is formed by guide elements and a closing element, creating a segmented system where each part addresses specific safety concerns independently.
Solution Approach 2:
The loop structure acts as an intermediary safety mechanism between the holding belt and the person's body. It provides an additional layer of protection that prevents the entire raising aid from slipping uncontrollably, mediating the interaction between the non-slip surface and the person's clothing or skin.
2Device complexity
If fixed-length pull handles are used on the holding belt, then the structural simplicity is maintained, but the adaptability to different person sizes and positions is reduced
Solution Approach 1:
The pull handles are designed with adjustable length capability through guide elements that allow the closing element to move along the guide. This dynamic adjustment enables the handles to adapt to different person sizes and positions while maintaining a relatively simple overall structure when not in use.
Solution Approach 2:
The adjustable handle system serves multiple functions: it provides secure grip assistance for different body sizes, accommodates various positioning scenarios, and maintains structural simplicity when not adjusted. The same mechanism serves both as a structural component and an adaptive feature.
3Ease of operation
If the pull handles are made length-adjustable to accommodate different positions, then the ease of operation for different users is improved, but the device complexity increases
Solution Approach 1:
The handle length adjustment mechanism uses simple guide elements and a movable closing element that can slide along the guide. This dynamic design allows easy adjustment of handle length to accommodate different user needs while keeping the mechanical complexity minimal through straightforward sliding motion.
Solution Approach 2:
The closing element can be easily manipulated by users to adjust the handle length according to their own size and positioning needs. The adjustment mechanism is designed to be user-friendly, allowing individuals to configure the device for themselves without requiring complex controls or assistance.

AI summary
The aid has a retaining belt (1) with a surface (2) attached at rump areas or a lower rear area of a person. Two pulling handles (3.1, 3.2) are laterally positioned at opposite sides of the surface of the belt. The handles are fixed together at the belt by ends (4.1, 4.2) of the handles. The handles are pulled by respective guide (6.1, 6.2) and connected to a strap (7) that is changeable in length opposite to the belt. The guides are provided in an area of lateral ends of the belt. The strap is attached at a bottom or upper limb of the person.
