Movement cushion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage cushions primarily provide local muscle relaxation and fail to effectively relax and reorient entire muscle complexes, and they often suffer from tangling and handling issues due to complex hose arrangements.
Innovation Solution
A pneumatically regulated movement cushion with independent chambers, each filled and emptied via a dedicated hose, featuring a guide channel for supply hoses to prevent tangling and improve handling, and a robust sheathing for protection, allowing for flexible and space-efficient routing of hoses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple supply hoses are used for each chamber, then each chamber can be filled and emptied independently, but the hoses become tangled and handling becomes difficult
Solution Approach 1:
Multiple supply hoses are merged into a single common supply hose that branches to individual chambers. This reduces the number of separate hoses the user must handle while maintaining independent control of each chamber through electronic valves at the chamber level.
Solution Approach 2:
A common supply hose acts as an intermediary component that connects the air source to multiple chambers through branching connections. This intermediary structure consolidates hose management while preserving individual chamber accessibility through electronic control valves.
2Adaptability or versatility
If supply hoses are routed freely between chambers, then installation is flexible, but the hoses tangle and create handling issues
Solution Approach 1:
The supply hose routing is organized in a structured dimensional pattern where hoses run along specific paths (longitudinally and transversely) between chambers rather than freely in three-dimensional space. This structured routing prevents tangling while maintaining installation flexibility.
Solution Approach 2:
The cushion is divided into distinct chamber sections with designated hose routing paths between them. Each segment has defined entry and exit points for supply hoses, creating an organized routing structure that prevents tangling while allowing flexible installation.
3Ease of manufacture
If local pressure is applied to muscles, then local muscle tension is relieved, but deep relaxation of entire muscle complexes is not achieved
Solution Approach 1:
Chambers are filled and emptied in periodic sequences that create wave-like motion patterns across the cushion surface. This periodic action propagates through entire muscle complexes rather than applying static local pressure, achieving deep relaxation through dynamic movement.
Solution Approach 2:
The system transitions from static local pressure application to dynamic wave-like motion. Chambers are sequentially filled and emptied to create moving pressure waves that traverse entire muscle complexes, providing deep relaxation through dynamic mechanical stimulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables deep relaxation and reorientation of muscle complexes by creating three-dimensional movement patterns, reduces hose tangling, and enhances user convenience and durability, making it suitable for various applications including paraplegics, bedridden individuals, and elderly patients.
Implementation Method 1
pneumatically regulated movement cushion, which consists of several separate chambers that are independent of one another and that can be filled and emptied by means of a suitable medium via a supply hose in each case
