Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing male contraception methods suffer from low reliability, high failure rates, discomfort, permanence, and potential health risks, disproportionately burdening women with reproductive health responsibilities.
Innovation Solution
A reversible male birth control implant device with a wireless-controlled sperm flow mechanism, using a biocompatible tubular component and wireless receiver to switch between sperm flow states, ensuring reliability, convenience, and reversibility without hormonal side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vasectomy is performed, then contraceptive efficacy is improved, but reversibility deteriorates
Solution Approach 1:
The patent applies a dynamic occlusion mechanism that can switch between open and closed states to block or allow sperm passage. The implant includes a movable occlusion element that can be positioned to block the vas deferens lumen or retracted to allow passage, enabling reversible contraception without permanent surgical alteration of the vas deferens structure.
Solution Approach 2:
The patent segments the vas deferens into three parts: proximal segment, implant segment with occlusion mechanism, and distal segment. This segmentation allows the occlusion function to be isolated to a specific segment while preserving the integrity and functionality of the proximal and distal segments, facilitating both effective blockage and potential reversibility.
2Adaptability or versatility
If condoms are used, then reversibility is maintained, but reliability deteriorates
Solution Approach 1:
The patent employs a self-contained implant with an integrated occlusion mechanism that automatically maintains the blocked state without requiring user action. The device is implanted surgically and then functions autonomously to block sperm passage, eliminating the user compliance issues associated with condoms while maintaining reversibility through controlled activation/deactivation of the occlusion mechanism.
3Ease of operation
If chemical and hormonal methods are used, then convenience is improved, but health risks worsen
Solution Approach 1:
The patent replaces chemical and hormonal mechanisms with a purely mechanical occlusion system. The implant uses a physical barrier and movable occlusion element to block sperm passage mechanically, eliminating the need for chemicals or hormones that could cause systemic side effects, while maintaining the convenience of a set-and-forget approach similar to hormonal methods.

AI summary
The present invention introduces a groundbreaking solution in the field of male contraception-a reversible male birth control implant device. The device offers enhanced flexibility in family planning by controlling the amount of sperm ejaculated. It consists of a tubular component surgically inserted into each severed vas deferens, with a wireless receiver attached. The wireless receiver receives external wireless signals and enables the device to switch between a state that permits the flow of sperm and a state that impedes it. The device also features an outlet for the safe elimination of obstructed sperm. The use of biocompatible materials and compatibility with medical imaging devices, such as MRI, ensures safety and usability. This innovative device empowers individuals with convenient and discreet control over their fertility, revolutionizing male contraception and opening new possibilities in reproductive health.
