Collapsible Intimate Hygiene Device with Fixed Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intimate hygiene devices, such as douches and enemas, often lack comfort, safety, and effectiveness, with many being non-disposable and causing unnecessary pressure or harm to mucosal regions, and existing solutions do not cater well to specific hygiene needs for vaginal and anal areas.
Innovation Solution
A portable, collapsible, and disposable device with a flexible casing and a fixed applicator nozzle, designed for ergonomic handling, providing controlled fluid delivery without excessive pressure, suitable for both vaginal and anal hygiene, and capable of standing without a valve, allowing for efficient cleaning and treatment of pelvic cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional douches with fixed structure are used, then fluid delivery is achieved, but comfort and ease of operation deteriorate due to rigid design and lack of adaptability
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid, fixed structure of conventional douches into a flexible, collapsible body that can dynamically adapt its shape and volume. The flexible material allows the device to collapse as fluid is dispensed, maintaining structural integrity while improving comfort and ease of operation during use.
Solution Approach 2:
The patent implements flexible shells and thin films by constructing the entire device body from flexible material that can bend and collapse. This flexible construction replaces rigid components, enabling the device to conform to anatomical shapes and improve user comfort while maintaining functional performance.
2Manufacturing precision
If shower douches with high water pressure are used, then deep cleaning is achieved, but harmful effects occur on the mucosa of the anal region
Solution Approach 1:
The patent applies parameter changes by controlling the fluid delivery pressure through the flexible collapsible design. As the body collapses during dispensing, it naturally regulates pressure to prevent excessive force, thereby achieving effective cleaning while avoiding mucosal damage that occurs with high-pressure shower douches.
3Reliability
If non-disposable devices are used, then device functionality is maintained, but hygiene and safety deteriorate due to repeated use and cleaning requirements
Solution Approach 1:
The patent implements disposable design by creating a single-use device that is discarded after one application. This eliminates hygiene and safety risks associated with repeated use and cleaning of non-disposable devices, while maintaining full functionality during the single use through the flexible collapsible construction.
4Stability of the object's composition
If rigid pouches are used, then structural stability is maintained, but portability and ease of handling deteriorate
Solution Approach 1:
The patent applies dynamics by creating a flexible collapsible body that transitions from a stable, filled state to a collapsed, portable state as fluid is dispensed. This dynamic transformation maintains structural stability when needed while dramatically improving portability and ease of handling during and after use.
