Garment Fly Opening for Urinary Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for female urination in a standing position are bulky, difficult to clean, and require multiple sizes due to non-personalization, making them impractical for discreet use and sharing, and often require disrobing or soiling.
Innovation Solution
A hand-held urinary device with a tubular design and a specially positioned fly opening in clothing, such as a skirt or trousers, allows for urine collection without disengaging the garment's securing mechanism, enabling discreet and hygienic urination while standing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large funnel-shaped device is used to enable standing urination, then ease of use is improved, but device size and portability deteriorate
Solution Approach 1:
The garment is divided into functional zones: a securement mechanism (waistband with belt) that remains engaged, and a fly opening that can be independently accessed. This segmentation allows the device to be used without disengaging the main securing mechanism, reducing the required device size while maintaining ease of use.
Solution Approach 2:
The fly opening extracts the access function from the main garment structure, creating a dedicated access point that can be opened and closed independently. This allows the urinary device to be inserted and removed without affecting the overall garment security, enabling a more compact device design.
2Reliability
If sealing devices are added to prevent urine leakage, then reliability is improved, but ease of cleaning and personalization deteriorate
Solution Approach 1:
The fly opening acts as an intermediary mechanism between the garment interior and exterior, providing a controlled access point that maintains sealing when closed but allows easy access when opened. This eliminates the need for complex sealing devices that would hinder cleaning, as the simple flap structure can be easily wiped and sanitized.
3Adaptability or versatility
If multiple sizes are provided to accommodate varying body sizes, then adaptability is improved, but device complexity and portability deteriorate
Solution Approach 1:
The fly opening design provides a universal access mechanism that works with garments of various sizes and styles. The opening can be positioned and sized appropriately for different body types, and the tubular device can accommodate different urethra sizes, eliminating the need for multiple specialized device sizes while maintaining adaptability.
4Ease of operation
If the fly opening is positioned to enable device insertion without disengaging the securing mechanism, then ease of operation is improved, but garment design complexity increases
Solution Approach 1:
The fly opening is pre-positioned and pre-sized in the garment fabric during manufacturing, creating a ready-to-use access point that requires no additional steps or complex mechanisms during operation. The opening is strategically located to provide direct access to the urethra area, simplifying the insertion process while maintaining a relatively simple garment design.

AI summary
A lower garment for a female person has a mechanism that when engaged, secures the garment to the female person, and a fly opening implemented at a specific position in a fabric of the garment, the fly opening comprising a substantially straight slit of a first length covered by a flap of fabric stitched to the fabric of the garment around the slit such that the slit is covered by the flap except for an un-stitched edge of the flap of a length equal to the length of the slit. The specific position in fabric of the garment is a position that enables the female person to engage a tubular portion of an external device through the fly opening, and to move the tubular portion to her vulva and insert same to position of the urethra without disengaging the mechanism that secures the garment to the female person.
