Retractable support handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static support handles in bathrooms, such as fixed grab bars, are inadequate for individuals with mobility issues as they are difficult to reach, occupy space, and cannot adjust with user repositioning, making it hard for them to stand up from a seated position.
Innovation Solution
A retractable support handle with a spring-loaded hinge that can be lowered to a horizontal position for use and automatically retracts to a vertical position for storage, allowing for easier movement and space-saving design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed grab bar is used, then it provides stable support, but it occupies space and is difficult to reach
Solution Approach 1:
The support bar is transformed from a fixed static structure to a dynamic movable one. The bar can rotate between a horizontal extended position for use and a vertical retracted position for storage, allowing it to adapt its position based on user needs while minimizing space occupation when not in use.
Solution Approach 2:
The support bar utilizes rotational movement to change its spatial orientation from horizontal to vertical. This dimensional transition allows the same structure to serve both as an accessible horizontal grab bar and a compact vertical storage element, effectively resolving the space occupation issue.
2Device complexity
If a fixed grab bar is used, then it provides structural simplicity, but it cannot adjust with user repositioning
Solution Approach 1:
The introduction of the spring-loaded hinge mechanism adds controlled dynamics to the structure. The spring provides automatic tension to return the bar to vertical position, while the hinge allows rotational movement. This maintains relative structural simplicity while enabling adaptability to user repositioning needs.
Solution Approach 2:
The spring-loaded mechanism provides self-service functionality by automatically returning the support bar to its storage position after use. The spring tension creates a self-resetting system that requires no manual intervention to return to the vertical position, maintaining simplicity while adding adaptability.
3Area of stationary object
If a retractable support handle is used, then it saves space when retracted, but it requires additional mechanical components
Solution Approach 1:
The support bar utilizes rotational movement to change its spatial orientation from horizontal to vertical. This dimensional transition allows the same structure to serve both as an accessible horizontal grab bar and a compact vertical storage element, effectively resolving the space occupation issue.
Solution Approach 2:
The spring-loaded mechanism provides self-service functionality by automatically returning the support bar to its storage position after use. The spring tension creates a self-resetting system that requires no manual intervention to return to the vertical position, maintaining simplicity while adding adaptability.

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 retractable support handle assists users in standing up by providing a usable handle that automatically returns to a compact position, preserving space and user mobility, thus enhancing independence and confidence.
Implementation Method 1
The spring-loaded hinge is configured to bias the support bar to the raised vertical position

AI summary
A retractable support handle includes a mounting bracket having a rear plate configured to secure to a mounting surface via one or more fasteners. A support bar includes a first end connected to a spring-loaded hinge within the mounting bracket and a second end extending outwardly from a slot disposed on a front plate of the mounting bracket. The support bar is rotatable between a raised vertical position and a lowered horizontal position. The spring-loaded hinge is configured to automatically return the support bar to the raised vertical position when the retractable support handle is not in use. A user may grasp and rotate the support bar to the lowered horizontal position to provide a support handle when needed. When the user releases the support bar, the spring-loaded hinge automatically retracts the support bar to the raised vertical position.
