Chair Foot Attachment for Controlled Wobble and Student Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children often struggle with excess energy, anxiety, hyperactivity, and boredom, which hinders their ability to focus on schoolwork, and existing solutions do not effectively address these issues while allowing for discreet energy expenditure during seated activities.
Innovation Solution
A chair foot attachment that transforms a standard school chair into a wobbling chair, enabling students to wiggle and wobble freely without lifting the chair legs off the floor, promoting blood flow and a calming influence, thereby enhancing focus and reducing stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standard school chair is used, then the chair is stable and stationary, but the student cannot expend excess energy or improve focus
Solution Approach 1:
The patent applies the dynamics principle by transforming a static chair into a dynamic one that allows controlled movement. The foot attachment includes a movable platform that can rock or pivot relative to the chair leg, enabling students to rock their feet and expend energy while remaining seated. This dynamic element resolves the contradiction by allowing energy expenditure without compromising the overall stability of the chair during academic work.
2Productivity
If the chair allows free movement, then energy can be expended, but the chair legs may lift off the floor and disturb others
Solution Approach 1:
The patent applies local quality by confining the movement to a specific localized area - the foot attachment platform - while keeping the rest of the chair and the student's upper body stationary. The movement is restricted to small oscillations at the foot level, which does not translate to chair leg movement or disturbance to others. This resolves the contradiction by allowing energy expenditure locally without creating harmful disturbances globally.
3Productivity
If the chair is made wobbly, then focus can be improved, but the chair stability decreases
Solution Approach 1:
The patent applies segmentation by separating the chair into two functional zones: a stable base (chair legs and seat) and a movable element (foot attachment platform). The foot attachment is connected to the chair leg but designed to move independently through rocking or pivoting motion. This segmentation allows the foot area to be dynamic for energy expenditure while the main chair structure remains stable for writing and reading, resolving the contradiction between wobbling for focus and stability for composition.

AI summary
A chair foot attachment for improving focus is a flexible hollow member having a height with side walls defining bottom edges of the hollow member and having an upper wall with a cavity extending downwardly into the hollow member from the upper wall. The cavity extends only partially into the hollow member and defines a cavity height that is less than the height of the hollow member. The cavity has an upwardly facing bottom surface for abutting a bottom of a chair foot when the chair foot is installed in the cavity. When a chair foot is positioned in the cavity, it permits an associated chair to wobble.
