One-Piece Rocking Exercise Device for Seated Blood Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged sitting leads to poor blood circulation in the lower extremities, particularly in individuals who cannot stand or walk due to mobility limitations, and existing exercise devices are often bulky, non-portable, and not designed for seated use.
Innovation Solution
A one-piece, lightweight exercise device with a longitudinal central axis and transverse central axis, featuring an arcuate section for floor contact and inclined ramps for foot placement, allowing users to rock back and forth while seated, promoting blood circulation without requiring standing or walking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional exercise devices are designed to be sturdy and long-lasting using metal and metal alloys, then strength and durability are improved, but weight and portability deteriorate
Solution Approach 1:
The exercise device uses a composite structure combining a foam core material with a plastic shell. The foam core provides structural strength and durability, while the plastic shell provides a smooth surface and lightweight construction. This composite approach achieves both strength and portability, allowing the device to be both sturdy and easily portable.
Solution Approach 2:
The device employs a foam core material with a porous structure that provides structural support while minimizing weight. The porous foam core maintains sufficient strength to support exercise functions while being significantly lighter than solid metal construction, enabling portability.
2Ease of operation
If exercise devices are designed to be large and open for stability and functionality, then exercise effectiveness is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The device uses a thin-walled plastic shell that encloses the foam core. This thin shell provides sufficient structural integrity for effective exercise while minimizing the overall size and weight, making the device portable yet functionally effective.
3Ease of operation
If exercise devices are designed for stationary use in gyms, then exercise functionality is improved, but adaptability to different locations and situations deteriorates
Solution Approach 1:
The exercise device is designed to be universally applicable in multiple settings including gyms, offices, homes, and during travel. Its compact size and lightweight construction allow it to be used in diverse locations while maintaining exercise functionality, making it adaptable to various situations.
4Strength
If exercise devices are made from dense materials for durability, then strength is improved, but ease of transport and storage deteriorate
Solution Approach 1:
The device combines foam core material with plastic shell to achieve durability without weight. The foam core provides the necessary structural strength for long-lasting use, while the plastic shell adds protection and maintains shape. This composite construction ensures durability while keeping the device lightweight for easy transport.
Solution Approach 2:
The foam core material uses a porous structure that provides structural integrity and durability while minimizing density and weight. This allows the device to be both durable for long-term use and easy to transport quickly.

AI summary
An exercise device is disclosed for facilitating blood circulation in the lower extremities of a person's legs and feet. The exercise device includes a one piece member having upper surface and a lower surface. The lower surface has an arcuate section designed to directly contact a floor. The arcuate section is located between first and second planar sections. Each of the first and second planar sections is inclined downward at an angle relative to the arcuate section. A pair of spaced apart ramps is formed in the upper surface and each extends downwardly from a back surface to a front surface. Each of the ramps is designed to receive a portion of a person's foot while an adjoining heel of each foot rest on the floor. The person can rock the exercise device back and forth by shifting his weight from one foot to the other.
