Modular Suction Grab Bar for Adaptable Bathroom Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding devices for sanitary areas, such as bathrooms, lack universal application and are not suitable for infirm or obese individuals due to insufficient holding force and adaptability to different surfaces.
Innovation Solution
A holding device with a hand grip arrangement and modular attachment means featuring at least two pairs of suction heads, coupled using separate coupling components like node or cross members, allowing for adjustable and secure attachment to various surfaces, including those with different slopes, and enabling easy detachment and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional holding devices with single suction heads are used, then the device structure is simple, but the holding force is insufficient for infirm or obese persons
Solution Approach 1:
The holding device is divided into multiple independent suction heads (at least two pairs) that can be separately attached to the wall. Each suction head acts as an independent force-generating element, and their combined effect provides sufficient holding force for infirm or obese persons while maintaining relatively simple individual component structures.
Solution Approach 2:
Multiple suction heads are combined into a single integrated hand grip arrangement. The coupling means (node or cross members) merge the force-generating capabilities of individual suction heads into a unified structure that provides both increased holding force and structural coherence.
2Adaptability or versatility
If fixed handles are installed permanently, then the holding force is reliable, but the adaptability to different surfaces and locations is limited
Solution Approach 1:
The holding device transitions from a fixed permanent installation to a dynamic removable system. The suction heads can be attached and detached as needed, allowing the device to adapt to different wall surfaces and locations without requiring permanent modification of the installation environment.
Solution Approach 2:
The hand grip arrangement with multiple suction heads is designed to be universally applicable to various even surfaces in sanitary areas. The same device can be used in bathrooms, showers, or other locations, and can be attached to different wall surfaces without modification, providing multi-functional versatility.
3Adaptability or versatility
If modular coupling components are used to connect suction heads, then the adaptability and adjustability increase, but the device complexity increases
Solution Approach 1:
The device is segmented into modular components (suction heads, coupling means, hand grip arrangement) that can be independently manufactured and assembled. This segmentation enables flexible configuration while keeping each individual component relatively simple in design.
Solution Approach 2:
Coupling means (node or cross members) serve as intermediary elements that connect the suction heads to the hand grip arrangement. These intermediaries provide standardized connection interfaces that simplify the overall assembly process while enabling configuration flexibility and adaptability.
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 device provides enhanced holding force and adaptability, ensuring safety and ease of use for elderly or infirm persons in sanitary areas, with the ability to be adjusted for different heights and surface types, and can be easily stored when not in use.
Implementation Method 1
a hand grip arrangement with an associated attachment means, which has at least two pairs of suction heads, of which the hand grip arrangement is able to be held firmly in position on an even surface
