Disposable Circumcision Apparatus with Round Blade Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circumcision apparatuses cause pain, bleeding, infection, and discomfort due to right-angle blade structures, inadequate anti-inflammation design, inconvenient locking mechanisms, and non-standardized tightness, leading to hematoma and prolonged recovery times.
Innovation Solution
A novel disposable circumcision apparatus with a balanus ferrule and fixture device featuring round angles, separate semi-ferrules for penis adaptation, a cavity for medication, and a flexible locking mechanism, ensuring comfortable and standardized operation with reduced pain and infection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a right-angle blade structure is used in the circumcision apparatus, then the device structure is simple, but the foreskin is easily clamped causing severe pain to the patient
Solution Approach 1:
The patent applies curvature by replacing the right-angle blade structure with a rounded blade structure. The rounded shape distributes the clamping force more evenly across the foreskin, preventing localized compression and severe pain while maintaining the simplicity of the device structure.
2Quantity of substance
If traditional external antiphlogistic treatment is used, then the treatment cost is low, but the anti-inflammation effect is insufficient and requires additional medication
Solution Approach 1:
The patent introduces a medication cavity as an intermediary structure within the apparatus. This cavity allows direct delivery of anti-inflammatory medication to the surgical site, enhancing the anti-inflammation effect without requiring additional external medications, thereby reducing overall treatment cost while improving reliability.
3Strength
If screw fixation is used for the locking device, then the locking strength is high, but manual manipulation is inconvenient and increases operation time
Solution Approach 1:
The patent transitions from static screw fixation to a dynamic locking mechanism that can be easily manipulated manually. The new design allows for quick engagement and disengagement through simple manual actions, maintaining sufficient locking strength while dramatically improving ease of operation and reducing operation time.
4Device complexity
If a fixed diameter balanus ferrule is used, then the device structure is simple, but it cannot adapt to penis erection and enlargement causing discomfort
Solution Approach 1:
The patent applies dynamics by making the balanus ferrule expandable rather than fixed. The ferrule can dynamically adjust its diameter to accommodate penis erection and enlargement during the procedure, providing adaptability while maintaining structural simplicity through an expandable design mechanism.
5Device complexity
If binding string is used to secure the foreskin, then the device structure is simple, but the binding string may move relative to the foreskin during expansion causing hematoma
Solution Approach 1:
The patent replaces the rigid binding string with a flexible elastic band. This elastic band maintains continuous contact with the foreskin during penis expansion, preventing relative movement and ensuring complete blood stream blockage while avoiding hematoma formation. The flexibility allows it to adapt to dimensional changes without compromising reliability.
