Segmented Calf Massager for Deep Vein Propulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current leg massagers are ineffective in promoting deep vein blood flow due to the deep location of leg deep veins, which are protected by the tibia bone and muscles, and the use of circumferential compression that interferes with blood flow rather than efficiently pumping blood towards the heart.
Innovation Solution
A portable deep vein leg massager with a harness and base holder plate that uses independent compression-decompression mechanical assemblies to apply targeted forces to the calf, powered by batteries and controlled by a timer switch, to simulate the natural muscle contractions and enhance deep vein blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If circumferential compression is applied to the entire leg, then massage coverage is improved, but deep vein blood flow is hindered due to protection by tibia bone and muscles
Solution Approach 1:
The leg massager is divided into multiple independent compression zones along the leg length, with each zone having independently controllable compression elements. This segmentation allows targeted compression of specific areas (calf, thigh, etc.) without circumferential compression that would block deep veins protected by bone and muscle structures.
Solution Approach 2:
Different regions of the leg receive different compression patterns and intensities tailored to local anatomical features. The compression elements are designed to apply force locally to superficial muscles and veins while avoiding areas where deep veins are protected by the tibia bone and muscle layers.
2Force
If air cuffs squeeze the entire leg circumference, then overall leg compression is improved, but blood flow through deep veins is trapped locally
Solution Approach 1:
The compression system uses multiple discrete compression zones rather than a single circumferential air cuff. Each zone can be independently activated and controlled, allowing compression forces to be applied in a sequential or selective manner that propels blood forward through the deep veins without trapping it locally.
Solution Approach 2:
The massager employs periodic compression and decompression cycles at different frequencies and durations for different leg regions. This periodic action mimics natural muscle pump mechanisms, creating pressure gradients that efficiently propel blood through the deep veins toward the heart.
3Reliability
If stationary power source is used, then device functionality is improved, but portability is reduced
Solution Approach 1:
The power system transitions from a fixed stationary power source to a dynamic portable power solution using rechargeable batteries. This allows the device to adapt to different usage environments including travel, home, and outdoor settings while maintaining full functionality through integrated battery packs and wireless control capabilities.
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 device effectively compels deep vein blood flow towards the heart by applying localized compression and decompression, reducing the risk of blood pooling and varicose veins, and is portable for use in various settings without the need for a stationary power source.
Implementation Method 1
Each stage independent mechanical assemblies have mechanical mechanism for applying a compressing-decompressing force to a calf conforming surface area
Implementation Method 2
stages with calf surface area plate-like segments pushed and pulled by each stage mechanical mechanisms... to compel deep vein blood toward the heart
Implementation Method 3
Power in the form of batteries are affixed to the shin bone plate for powering the mechanical mechanism to compress and decompress each stage segmented calf surface component

AI summary
A portable deep vein leg massager apparatus with harness attaching to a human lower leg having a segmented calf surface staged assemblies compressing and decompressing the calf muscle directionally toward the shin. The segmented staged electromechanical assemblies act synchronously to compel deep vein blood vessels to push blood from the ankle towards the heart.
