Stair Climber Platform with Overturning Mechanism for Narrow Stairs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aids for people with motor disabilities to navigate staircases, such as goods lifts and stairclimbers, require significant structural work, are costly, and have a negative visual impact, making them unsuitable for all buildings and aesthetically unappealing, especially in historical structures, and often require assistance and emphasize the user's disability.
Innovation Solution
A mobility aid system comprising a box-shaped frame with a lifting platform that can be attached to staircases without major architectural changes, featuring a driving mechanism for vertical movement and an overturning mechanism for horizontal alignment, allowing for easy installation and minimal visual obstruction when not in use, and can be customized for various staircase configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed stairclimbers anchored to the wall are used, then staircase navigation is enabled, but installation and maintenance costs increase significantly
Solution Approach 1:
The stairclimber is divided into modular components that can be easily assembled and disassembled. The frame structure consists of separate sections that can be attached to individual steps, allowing for simple installation without significant structural modifications and easy maintenance by replacing only the affected module.
Solution Approach 2:
The device incorporates self-stabilizing mechanisms and automatic positioning features that reduce the need for professional installation and maintenance services. The system can be adjusted and maintained by users or non-specialists through simple operations.
2Reliability
If fixed stairclimbers anchored to the wall are installed, then staircase access is provided, but the staircase appearance is significantly affected
Solution Approach 1:
The stairclimber employs a dynamic design where the frame and platform can move or adjust their position. When not in use, the platform can be retracted or positioned to minimize visual impact, while during operation it provides full accessibility. This dynamic capability allows the device to adapt its appearance based on usage needs.
3Adaptability or versatility
If free stairclimbers are used, then flexibility for narrow staircases is improved, but user independence decreases due to requiring guidance
Solution Approach 1:
The stairclimber incorporates sensors and control systems that provide real-time feedback about the device's position, speed, and stability. This feedback enables automatic adjustments and safety interventions, allowing users to operate the device independently without requiring constant guidance from another person.
4Reliability
If goods lifts are installed, then vertical transport is enabled, but structural work and installation costs increase
Solution Approach 1:
The stairclimber is designed as a multi-functional device that can navigate various staircase configurations (straight, L-shaped, U-shaped) and adapt to different step dimensions. This universal design eliminates the need for custom structural modifications for each installation location, as the device can be configured to work with existing staircase structures.
