Variable-Length Bed Exercise Equipment for Lower Body Strengthening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients lying in bed for extended periods experience weakened lower body muscles due to limited physical activity, and existing exercise equipment requires them to be out of bed or involves complex configurations.
Innovation Solution
A lower body exercise equipment comprising a first and second support element, a variable-length connection element, and a stand, designed to be placed on a bed, allowing patients to perform exercises while lying down without additional complicated structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lower body exercise equipment is used, then patients can exercise their lower bodies, but they must be out of bed or require complicated additional structures
Solution Approach 1:
The exercise equipment is divided into separate functional components: a first support element for the lower body, a second support element for the upper body, and a connection element linking them. This segmentation allows each component to be simple and independent, eliminating the need for complex integrated structures while enabling effective lower body exercise.
Solution Approach 2:
The support elements are designed to serve multiple functions: they provide structural support, enable exercise movement, and can be positioned flexibly on the bed. The connection element serves both as a structural link and as a guide for exercise motion, reducing the need for additional specialized components.
2Reliability
If patients exercise with conventional equipment, then lower body muscles can be strengthened, but they must leave the bed
Solution Approach 1:
The connection element acts as an intermediary between the first support element (lower body) and the second support element (upper body). It transmits the force and motion generated by upper body movement to facilitate lower body exercise, enabling patients to strengthen leg muscles while remaining in bed without requiring direct contact or complex mechanical linkages.
3Device complexity
If simple support elements are used, then equipment complexity is reduced, but the ability to provide effective exercise resistance is limited
Solution Approach 1:
The connection element is designed to be dynamically adjustable in length and configuration. This allows the resistance and range of motion to be modified according to patient needs without adding complex mechanical resistance mechanisms. The dynamic adjustment of the connection element provides variable exercise intensity while maintaining overall structural simplicity.
