Grooved Sleeve Footrest Assembly for Tool-Free Desk Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physical activity devices for students, such as the FOOTFIDGET, are difficult to install, not easily movable between desks, and challenging to adjust in height to accommodate different users, limiting their practicality and user comfort.
Innovation Solution
A physical activity device featuring elongated sleeves with grooves and loops that can be easily attached and detached from tubular support members, allowing for adjustable height and ergonomic positioning, enabling quick installation and relocation without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal foot assembly with elastic bands is used, then students can expend nervous energy and improve focus, but the device becomes difficult to install and cannot be easily moved between desks
Solution Approach 1:
The device is divided into separate components: a footrest assembly and a desk-mounted base assembly connected by adjustable straps. This segmentation allows the footrest to be easily attached and removed from different desks without permanent installation, resolving the contradiction between versatility and installation ease.
Solution Approach 2:
The base assembly is designed to be universally compatible with different desk types and sizes through adjustable straps and positioning mechanisms. This universal design enables the same device to be used across multiple desks in a classroom, achieving versatility while maintaining easy installation and relocation.
2Reliability
If the foot rest is fixed in position, then it provides stable ergonomic support, but it cannot be quickly adjusted to meet the needs of different students
Solution Approach 1:
The footrest position is made dynamically adjustable through movable straps with multiple positioning holes and buckles. Students can quickly adjust the footrest height and position to match their ergonomic needs, while the connection mechanism maintains stable support when positioned. This resolves the contradiction between reliable ergonomic support and quick adjustability.
3Manufacturing precision
If the device uses multiple attachment points and adjustment mechanisms, then it provides accurate ergonomic positioning, but it increases device complexity and difficulty of adjustment
Solution Approach 1:
Adjustment mechanisms are strategically placed at specific locations on the footrest and base assembly where they are most effective. The straps are positioned to provide optimal ergonomic support, and adjustment holes are spaced to give precise positioning control. This localized placement of adjustment features achieves accurate positioning while minimizing overall device complexity.

AI summary
The disclosure features physical activity devices that include (a) a central footrest, configured to receive at least a portion of a foot of a user, (b) a plurality of elongated sleeves, each sleeve having an inner and an outer surface, and being configured to at least partially enclose an elongated tubular support member, and having spaced grooves in its outer surface extending generally perpendicular to a longitudinal axis of the sleeve, and (c) at least two loops extending from the footrest, the loops being configured to be received by the grooves so that the sleeves support the footrest above a surface on which the tubular support members are positioned. The disclosure also features methods of using such devices.
