Chair Platform Assembly for Safe Sitting Over a Desk Treadmill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing office equipment solutions for exercise treadmills do not provide a safe and versatile method for using a standard office desk chair when the treadmill is not in use, often requiring the treadmill to be moved or stored, and do not accommodate a wide range of chair types and sizes, nor do they allow for uninterrupted access to a full-sized desktop.
Innovation Solution
A platform and desk assembly that supports and stabilizes a standard office desk chair over an exercise treadmill when the treadmill is not in use, allowing the treadmill to remain in place while providing a height-adjustable desk for both standing and sitting positions, compatible with various treadmill and chair sizes, and featuring wheels and grooves to secure the chair in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the treadmill is moved or stored when not in use, then the user can safely use their office chair, but the user loses access to their full-sized desktop and requires extra time and effort to move the treadmill
Solution Approach 1:
A platform is introduced as an intermediary component between the treadmill and the office chair. The platform has a recess that receives the chair, allowing the chair to be positioned safely over the treadmill without direct contact. This mediator enables the chair to be used securely while the treadmill remains in place, eliminating the need to move the treadmill while maintaining safety.
2Ease of operation
If the desk is lowered to accommodate sitting on the treadmill, then the user can sit comfortably, but the user loses access to the full-sized desktop and computing equipment
Solution Approach 1:
The desk system is segmented into two independent components: a full-sized stationary desktop that remains in its original position, and a movable desk surface that can be positioned over the treadmill. This allows the user to have access to the full-sized desktop when not exercising, and to position the movable desk surface over the treadmill when exercising, without compromising either function.
3Adaptability or versatility
If a standard office chair is placed directly on the treadmill, then the user can use their preferred chair, but the chair may rock or damage the treadmill belt due to wide legs
Solution Approach 1:
The platform serves as a mediator between the chair and treadmill. It features a recess that is shaped and sized to receive the chair legs, providing a stable platform that prevents rocking. The recess confines the chair legs, distributing the weight evenly and preventing the wide chair legs from directly contacting and potentially damaging the treadmill belt.
4Reliability
If the treadmill is folded under the desk, then the treadmill can be stored in place, but the user loses leg space when sitting beneath the desk
Solution Approach 1:
Instead of folding the treadmill vertically under the desk (occupying vertical space), the platform extends the usable space horizontally by creating a recess that receives the chair. This dimensional change allows the chair and user legs to be positioned in the horizontal recess space rather than requiring vertical clearance, maintaining leg space while keeping the treadmill in place.

AI summary
Exercise treadmill chair platform that resides horizontally over a treadmill when it is not in use to stabilize an office chair while it resides beneath the desk. The platform has a top and bottom flat plate, aligned, square or rectangular shaped, and of a low profile, that slides over the treadmill to cover the belt when the treadmill is not in use, thus enabling the user to safely sit at the desk without having to store away the treadmill. The platform may further comprise a right and left side wall; and, four corner wheels to assist the user in moving the platform, and two bumpers to protect the wheels from entanglements. The top flat plate further comprises oval shaped grooves arranged in a circle, designed to house the wheels of a variety of types of swivel chairs in order to keep the chair from rolling off of the platform.
