Under-Desk Pedal Exercise Device with Integrated Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chair-based exercise devices are large, cumbersome, and ineffective, failing to provide a substantial workout while being impractical for use in small spaces or during other activities, as they do not elevate heart rate or breathing and require user attention.
Innovation Solution
A compact exercise apparatus comprising a pedal assembly, brake assembly, and adjustable elongated bar that attaches to a chair support, allowing for pedaling while seated, with optional features like resistance adjustment, electricity generation, and monitoring of exercise statistics, designed to fit under a desk and accommodate various chair types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If exercise devices are made compact to fit in small spaces, then space utilization improves, but workout effectiveness deteriorates
Solution Approach 1:
The exercise device is nested within the chair structure, with the pedal mechanism integrated into the chair seat and the resistance mechanism housed within the chair frame. This nesting approach allows the exercise functionality to be contained within the existing chair volume, achieving compactness without sacrificing workout effectiveness through properly sized resistance mechanisms and pedal strokes.
Solution Approach 2:
The chair serves multiple functions: it provides standard seating for work activities and simultaneously functions as an exercise device through the integrated pedal mechanism. This multi-functionality eliminates the need for separate exercise equipment, achieving compactness by combining two functions in one object while maintaining workout effectiveness through dedicated exercise components.
2Volume of moving object
If exercise devices are made compact to fit under desks, then space utilization improves, but positioning accuracy deteriorates
Solution Approach 1:
The exercise device is segmented into modular components: the pedal mechanism is integrated into the chair seat, the resistance mechanism is housed in a separate compartment within the chair frame, and the power generation system is positioned in the base. This segmentation allows each component to be independently positioned and adjusted, achieving proper positioning accuracy while maintaining overall compactness for placement under desks.
3Ease of operation
If exercise devices require user attention to operate, then ease of operation deteriorates, but workout effectiveness improves
Solution Approach 1:
The exercise device automatically generates and tracks workout data through the integrated power generation system and sensors, eliminating the need for user attention to monitor or record metrics. The system self-regulates resistance based on pedaling speed and automatically logs workout statistics, allowing users to exercise while working without requiring their attention, thus improving ease of operation while maintaining workout effectiveness through consistent automated tracking.

AI summary
An apparatus and methods of attaching an exercise device to a chair to provide for a user of the chair to perform exercises. The apparatus generally includes a chair support section configured to be attached to the chair, and an exercise device that includes a support that is positioned on the floor. The chair support section and exercise device are configured to be engaged together when the user is exercising.
