Mobile Standing Frame With Slope Sensing and Anti-Tipping Foot Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile standing frames lack user-adjustable features and stability when transitioning between seated and standing positions, particularly on slopes, and are prone to tipping during locomotion.
Innovation Solution
A mobile standing frame with motor-driven wheels, adjustable components for user fit, and a slope sensor that adjusts the frame's position based on slope angle to prevent tipping, featuring a low center of mass and a forward-moving foot plate to stabilize the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mobile standing frame is designed with a single actuator motor to raise and lower the frame, then device complexity is reduced, but the ability to independently control foot plate position for tipping prevention is lost
Solution Approach 1:
The single actuator motor is designed to perform multiple functions: raising and lowering the mobile standing frame, and independently controlling the foot plate position. This multi-functionality reduces device complexity while maintaining the reliability needed for tipping prevention through coordinated control of these functions.
2Stability of the object's composition
If the center of mass is positioned lower in the standing configuration, then stability is improved, but the structural height of the device is reduced
Solution Approach 1:
The foot plate is designed to move forward in the horizontal dimension when transitioning to standing configuration, rather than only moving vertically. This forward movement extends the fulcrum length and shifts the effective center of mass position, improving anti-tipping stability without compromising the necessary vertical device height for user comfort.
3Ease of operation
If manual adjustment control elements are made easily accessible, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Multiple adjustment functions are combined into integrated control elements that can be easily accessed by the user. Rather than having separate controls for each adjustment parameter, the design merges these controls into accessible locations, improving ease of operation while managing device complexity through functional integration.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user comfort and stability by allowing easy adjustments and preventing tipping, ensuring safe and intuitive transitions between seated and standing positions, especially on inclines and declines.
Implementation Method 1
a slope sensor, such as a gyroscope, will detect the slope
Implementation Method 2
a single actuator motor raises and lowers the mobile standing frame
Implementation Method 3
the mobile standing frame will be lowered depending upon the angle of the decline

AI summary
A mobile standing frame is described that is designed to raise a user from a seated into a standing position, and return the user back to a seated position. The mobile standing frame is provided with a number of unique features that improve the user experience when using the mobile standing frame. For example, the mobile standing frame can be provided with a number of easily accessible individual user adjustment features (i.e. manual adjustment control buttons) that allow easy adjustment of components of the mobile standing frame to accommodate the size of the user. The mobile standing frame also includes a slope sensor to automatically lower the frame of the mobile standing frame from a fully standing position based on the sensed slope of a surface that the mobile standing frame is traveling along.
