Automated Lift Platform for Adjustable Height Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional step ladders pose risks of balance loss and physical strain due to the need for users to step and climb, particularly for those with physical limitations or seniors, as they require fixed height steps that may not align with task requirements, leading to potential falls and discomfort.
Innovation Solution
A step ladder with a moveable platform that automatically raises and lowers vertically along support legs, powered by a mechanical or electrical system, and equipped with safety features like a safety strap and optional support brace to enhance balance and stability, allowing users to adjust height without stepping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional step ladders with fixed height steps are used, then the structure is simple and easy to manufacture, but users experience balance loss and physical strain when climbing
Solution Approach 1:
The ladder transforms from a static structure with fixed steps to a dynamic structure where the standing platform can automatically move vertically along the support legs. This allows the platform to adapt its position automatically, eliminating the need for users to manually climb fixed steps while maintaining structural simplicity through the use of automated movement mechanisms.
Solution Approach 2:
The patent replaces the manual mechanical climbing action with an automated mechanical or electrical system. The moveable platform is powered by a motorized mechanism that automatically raises and lowers the user, substituting the user's physical climbing effort with an automated propulsion system integrated into the ladder's support structure.
2Adaptability or versatility
If fixed height steps are provided, then the device structure is simple, but the height may not align with task requirements causing users to stretch and lose balance
Solution Approach 1:
The standing platform is designed to be dynamically adjustable in height, moving automatically along the support legs to reach the optimal position for different tasks. This eliminates the need for multiple fixed steps while providing continuous height adaptability, allowing users to achieve task-aligned heights without stretching or losing balance.
3Extent of automation
If users must take steps to elevate, then the ladder structure remains simple, but physical energy is expended and risk of falling increases
Solution Approach 1:
The patent substitutes the user's manual stepping action with an automated motorized system. A moveable platform powered by a mechanical or electrical motor automatically transports the user to the desired height, eliminating physical exertion and the associated fall risks while integrating the movement mechanism into the ladder's existing support structure.
Solution Approach 2:
The ladder system provides self-service by automatically positioning the standing platform at the required height without user intervention for climbing. The motorized mechanism detects or receives input for the desired height and autonomously moves the platform, making the ladder serve itself in the height adjustment function.

AI summary
An automated system for raising and lowering a person to various desired levels enables the person to more comfortably and safely perform activities and tasks that require them to be at an elevated position relative to floor or ground surface. This system can comprise a lift platform attached to a series of vertical rails. The lift platform moves vertically along the rails, a user elevates to a desired position or height to perform the intended task. This system enables the user to determine their exact position instead of being at predetermined heights from using conventional devices such as ladders or stools. Once on the lift platform, a user can further secure themselves to the lift platform with a brace attached to the vertical rails. This brace would fit around the user's back and side straps would secure the brace to the vertical rails of the system.
