Pet Absorbent Core Fit via Overlapping Elastic Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles for pet animals face issues with the absorbent core displacement due to elastic element contraction, leading to potential leakage of body exudates, especially at the ventral region end edges, which can separate from the pet's body during movement.
Innovation Solution
Incorporating a ventral side elastic element that extends in the transverse direction within the absorbent article, ensuring the absorbent core's first end portion overlaps the elastic element in a planar view, maintaining a high fit with the pet's body and preventing leakage by contractile force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the elastic elements are positioned at a predetermined distance from the end edges of the absorbent core, then the absorbent article can be manufactured with standard positioning, but the absorbent core becomes prone to displacement and separation from the pet's body during movement
Solution Approach 1:
The elastic elements are positioned to overlap with the end edges of the absorbent core in the flat state, so that when the absorbent article is put on the pet, the elastic elements automatically contract to secure the absorbent core to the body contours before any movement occurs. This preliminary positioning ensures reliable fit without requiring complex adjustment mechanisms.
2Stability of the object's composition
If the elastic elements contract to secure the absorbent article to the body, then the fit is improved, but the absorbent core may be pulled away from the body edges causing leakage
Solution Approach 1:
The elastic elements serve as an intermediary between the absorbent core and the body. By positioning the elastic elements to overlap the end edges of the absorbent core, the contraction force is transmitted through the elastic elements to secure the absorbent core to the body contours, preventing both displacement and leakage simultaneously.
3Area of stationary object
If the absorbent core is made larger to ensure coverage, then the absorbent area is increased, but the end edges are more prone to separation from the body during movement
Solution Approach 1:
The elastic elements are pre-positioned to overlap with the end edges of the absorbent core, creating a securing mechanism before the absorbent article is put on the pet. This ensures that even when the absorbent core is made larger for comprehensive coverage, the elastic elements will contract to maintain reliable contact with the body contours during movement.
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 restricts leakage of body exudates by maintaining a high degree of contact between the absorbent core and the pet's body, ensuring a stable fit even during movement.
