Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals, particularly women and older men, experience discomfort and health issues such as urine leakage, hemorrhoids, and poor blood circulation due to pregnancy, childbirth, menopause, prostatic hyperplasia, sedentary lifestyles, and bedridden conditions, which current pads fail to adequately address.
Innovation Solution
A pad for the human body featuring a sheet body made of fibers with a polymer substrate and pyroelectric materials like kaolin, forsterite, maifan stone, montmorillonite, and tourmaline, which are polarized under an electric field to enhance blood circulation and reduce discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pads are used, then basic absorption function is provided, but blood circulation improvement and muscle function enhancement are not achieved
Solution Approach 1:
The pad incorporates a composite material containing pyroelectric particles (such as PVDF) embedded in the absorbent core and/or surface layers. This composite structure enables the pad to generate electrical signals through temperature changes, stimulating blood circulation and muscle function while maintaining absorption capabilities.
Solution Approach 2:
The pad utilizes changes in temperature parameters to trigger pyroelectric effects. When the pad contacts the body, temperature variations generate electrical signals that stimulate physiological functions. The patent also mentions adjusting parameters like particle concentration, size distribution, and material composition to optimize both therapeutic effect and absorption performance.
2Reliability
If pyroelectric materials are added to enhance blood circulation, then therapeutic effect is improved, but manufacturing complexity increases
Solution Approach 1:
The patent extracts the pyroelectric functional component as a separate additive material that can be mixed with or embedded in the conventional pad structure. This allows manufacturers to incorporate the therapeutic function without completely redesigning the manufacturing process, simply by adding pyroelectric particles during the forming stage.
Solution Approach 2:
The pyroelectric particles act as an intermediary between the thermal environment (body heat) and the biological tissue. They convert temperature changes into electrical signals that stimulate blood circulation, serving as a bridge that translates physical environmental changes into therapeutic biological effects without requiring complex mechanical or electronic systems.
3Reliability
If multiple pyroelectric materials are combined, then therapeutic effectiveness is enhanced, but material cost and processing difficulty increase
Solution Approach 1:
The patent employs different pyroelectric materials with complementary properties in different regions or layers of the pad. For example, certain materials may be concentrated in areas targeting specific muscles or circulation pathways. This local differentiation optimizes therapeutic effects for specific conditions while managing overall material complexity.
