Adhesive Urine-Absorbing Sheath With External Pad Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urine absorbing devices for men do not provide a removable sheath that securely attaches to the penis and includes an adhesive layer and external absorbent pad to prevent movement, while being economical and effective.
Innovation Solution
A urine absorbing sheath with a cylindrical sheath, elastic liner, absorbent layer, adhesive layer, and rubber guiding member, designed to securely attach to the penis and include an external absorbent pad for urine absorption, using materials like polyurethane, cellulose, and sodium polyacrylate, with straps and adhesive for secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a urine absorbing device is designed to be removable and portable, then ease of operation is improved, but secure attachment and stability may worsen
Solution Approach 1:
The device is divided into a removable sheath portion and a separate absorbent pad portion that can be attached and detached independently. The sheath can be removed without removing pants, while the absorbent pad remains secured to the underwear through adhesive layers, allowing easy removal while maintaining secure attachment during use.
Solution Approach 2:
An adhesive layer acts as an intermediary between the absorbent pad and the underwear, providing secure attachment. The adhesive layer allows the device to be firmly attached during use but can be easily removed when needed, resolving the contradiction between secure attachment and ease of removal.
2Stability of the object's composition
If an adhesive layer is added to secure the sheath to the penis, then stability is improved, but device complexity increases
Solution Approach 1:
The adhesive layer is integrated directly into the sheath structure, merging the attachment function with the sheath itself. This eliminates the need for separate attachment mechanisms, providing stable adhesion while maintaining simple device structure and ease of manufacture.
3Reliability
If an external absorbent pad is placed between the penis and testicles, then urine absorption capability is improved, but device complexity increases
Solution Approach 1:
The external absorbent pad is integrated with the sheath and securing members as a single unit, merging multiple functions (absorption, attachment, and positioning) into one component. This provides effective urine absorption while simplifying the overall device structure and reducing the number of separate parts.
Solution Approach 2:
The absorbent pad serves multiple functions: it absorbs urine, provides structural support, and works in conjunction with the adhesive layer and securing members to maintain device positioning. This multi-functionality improves urine absorption capability while avoiding the need for additional separate components.
4Stability of the object's composition
If straps are added to keep the sheath in place, then stability is improved, but ease of manufacture worsens
Solution Approach 1:
The straps are integrated into the sheath as a single molded piece rather than separate components. This merging of the strap function into the main sheath structure improves positioning stability while maintaining ease of manufacture through single-step molding processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sheath effectively absorbs urine without the need to remove pants, maintaining secure attachment and economical implementation.
Implementation Method 1
The sheath 22 may have the absorbent layer 27 entirely extending about an inner surface thereof. The absorbent layer 27 may absorb urine or any other liquid
Implementation Method 2
The absorbent layer 27 may be made of cellulose, fleece or any other suitable material enclosing sodium polyacrylate or any other absorbent material
Implementation Method 3
The adhesive portion 42 may be used to adhere the sheath 22 to the user's penis
Implementation Method 4
The open top portion of the sheath 22 may include the elastic liner 26 extending about a perimeter thereof
