Pet Absorbent Article Gather Portions Inverted U-Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles for pets with urethral openings positioned further forward than the base of the hind legs, such as miniature dachshunds, tend to incline inward when put on, leading to inadequate coverage of the urinary organ and potential urine leakage, along with physical stress on the pet's sex organ due to shorter gather configurations.
Innovation Solution
An absorbent article designed with a liquid permeable top sheet and a liquid impermeable back surface layer, featuring a first and second gather portion that can be releasably joined to ensure proper alignment and coverage, along with a manufacturing method that includes folding and cutting steps to form these portions, allowing for improved fit and reduced stress on the pet's urinary organ.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upright part of the gather is configured to be shorter, then the gather is easy to incline inward during putting on, but the gather can no longer cover the back side of the urinary organ and urine may leak
Solution Approach 1:
The invention transitions from a two-dimensional flat gather structure to a three-dimensional structure by folding the gather upward and outward to form an inverted U-shape. This dimensional change allows the gather to maintain adequate length for coverage while preventing inward inclination during putting on, as the folded structure provides geometric stability.
Solution Approach 2:
The gather is designed with dynamic characteristics by making it flexible and foldable rather than rigid. The inverted U-shape configuration allows the gather to adapt its shape during the putting-on process while maintaining its functional form, balancing ease of operation with reliability.
2Ease of operation
If the upright part of the gather is configured to be shorter, then the gather is easy to incline inward, but intense stress is applied to the base of the sex organ and the pet may be physically stressed
Solution Approach 1:
By folding the gather upward and outward to form an inverted U-shape, the invention distributes the contact area and reduces point stress on the base of the sex organ. The three-dimensional configuration spreads the mechanical load across a larger area, reducing intense stress while maintaining ease of putting on.
3Reliability
If the gather is configured to prevent inward inclination, then urine leakage is prevented, but the structure becomes more complex
Solution Approach 1:
The invention uses a dynamic folding structure rather than a complex rigid mechanism. The gather is simply folded upward and outward to form an inverted U-shape, which is achieved through flexible material properties rather than additional components or complex structural elements, thus maintaining simplicity while preventing inward inclination.
4Reliability
If the gather is configured to cover the back side of the urinary organ, then urine leakage is prevented, but the upright part must be longer which makes it difficult to put on
Solution Approach 1:
The invention solves the length problem by utilizing the third dimension (vertical folding) rather than simply increasing the horizontal length. The gather is folded upward to form an inverted U-shape, which provides adequate coverage of the urinary organ while the folded configuration makes the overall structure more compact and easier to manipulate during putting on.
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 absorbent article effectively prevents urine leakage and reduces physical stress on the pet by ensuring the gather portions remain aligned with the urinary organ, maintaining coverage and comfort during use.
Implementation Method 1
an absorbent core disposed between the top sheet and the back surface layer
Implementation Method 2
a liquid permeable top sheet
Implementation Method 3
a liquid impermeable back surface layer disposed on a second face of the absorbent core
