Solution Overview

Problem

Conventional pads with smooth or nubbed surfaces are inefficient in reducing swelling and lymphological treatment or stimulation due to their homogeneous structure, which fails to optimally support the targeted outflow of lymph fluid along lymph channels.

Innovation Solution

A pad with a periodic surface structure featuring elongated, wavy elements that mimic wave-like patterns, allowing for a guided lymphatic drainage by creating channels that align with the natural course of lymph vessels, enhancing the massage effect and lymphatic stimulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a smooth or nubbed surface is used on the pad, then the manufacturing is simple, but the lymphological treatment effectiveness is poor due to homogeneous structure

Engineering Contradiction:
Improvesurface structure simplicityVSAvoidlymphological treatment effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The pad surface is divided into different zones with distinct functions: wavy structures create channels for lymph flow in certain areas, while nubbed structures provide massage stimulation in other areas. This local differentiation allows each region to perform its specific function optimally, improving overall lymphological treatment effectiveness while maintaining manufacturing simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The homogeneous surface is segmented into multiple functional elements including wavy channels and nubbed regions. This segmentation creates a heterogeneous surface structure that can simultaneously provide guided lymph drainage through waves and mechanical stimulation through nubs, resolving the contradiction between manufacturing simplicity and treatment effectiveness.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If a homogeneous surface structure is used, then the pad is easy to manufacture, but it fails to guide lymph fluid outflow in a preferred direction

Engineering Contradiction:
Improvesurface structure uniformityVSAvoidlymph fluid guidance capability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The surface structure incorporates wavy regions with specific directional characteristics that guide lymph fluid flow along preferred paths. These localized wavy structures create channels that direct lymph movement, while maintaining overall manufacturing simplicity through consistent fabrication processes.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Wavy structures with curved surfaces are introduced to the pad surface. These curved geometries naturally guide lymph fluid flow along the wave contours, creating preferred drainage directions without requiring complex manufacturing processes. The curvature of the waves provides the guiding function while maintaining ease of manufacture.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Device complexity

If conventional smooth pads are used, then the device complexity is low, but the massage effect and swelling reduction are insufficient

Engineering Contradiction:
Improvepad structure simplicityVSAvoidswelling reduction efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The pad surface is segmented into multiple functional elements including wavy channels and nubbed regions. This segmentation creates a heterogeneous surface structure that can simultaneously provide guided lymph drainage through waves and mechanical stimulation through nubs, resolving the contradiction between manufacturing simplicity and treatment effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pad integrates multiple surface structures (wavy regions and nubbed regions) into a single composite surface. This composite approach combines the benefits of channel guidance and mechanical massage stimulation, enhancing swelling reduction efficiency while maintaining relatively simple device construction through single-material fabrication.

Inventive Principle:
Principle #40Composite materials

AI summary

The pelotte (1) has a cushion made of a flexible material, where a surface of the pelotte exhibits a periodic surface structure made of long-drawn-out elements i.e. wave trains (2), which are separated by gaps (3). Distance between the wave trains is about 0.1 millimeter to 3 centimeters. The periodic surface structure is located on the surface such that the wave trains and gaps run in dependence of a lymph channel to be covered with an angle ranging between minus 45 degrees and plus 45 degrees, relative to anatomical process of lymph vessels. An independent claim is also included for a method for producing a pelotte.
