Copper T-Shaped Cervical Device for HPV Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack an effective solution for reducing the incidence and prevalence of human papillomavirus (HPV) types 16 and 18, which are major contributors to uterine cervical cancer, and for enhancing local immunity in women, while also serving as a contraceptive device.
Innovation Solution
A uterine cervical device comprising copper, designed to be placed between the cervix and uterus, with a T-shaped frame and copper filaments, modifies the cervical microbiota, reduces inflammatory responses, and increases leukocyte levels, thereby enhancing local immunity and preventing HPV-related cancers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional contraceptive methods are used, then contraception is provided, but protection against HPV and cervical cancer is not achieved
Solution Approach 1:
The intrauterine device is designed to perform multiple functions simultaneously: contraception through copper ion release, HPV prevention through microbiome modification, and immune system stimulation through leukocyte attraction. This multi-functionality resolves the contradiction by integrating several protective mechanisms into a single device that addresses both contraceptive needs and cervical cancer prevention.
Solution Approach 2:
The device combines copper filaments with a T-shaped frame structure, creating a composite material system that releases copper ions while maintaining structural integrity. This composite approach enables the device to achieve both contraceptive efficacy and antiviral protection through the synergistic effects of the materials used.
2Reliability
If copper area is increased to enhance HPV protection, then immune response is improved, but device complexity increases
Solution Approach 1:
The copper is divided into multiple filaments arranged in a specific pattern on the T-shaped frame, rather than using a single large copper component. This segmentation allows for optimized copper distribution that enhances immune response while maintaining manageable device complexity through modular construction.
Solution Approach 2:
The device specifies a copper area between 380-524 mm² with optimal ranges identified through research. By optimizing this critical parameter, the device achieves maximum immune stimulation and HPV protection efficacy without unnecessarily increasing complexity, as the copper area is carefully controlled within specific boundaries.
