Pet Absorbent Article Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles for pets, particularly those with urethral openings positioned forward, face issues with urine leakage due to inadequate coverage, and current solutions require additional members to maintain a compact, wrapped state, increasing costs.
Innovation Solution
An absorbent article with a liquid-permeable top layer, a liquid-impermeable back layer, and an absorbent core, configured in a rectangular shape with a locking member that allows the article to be wrapped around a pet's waist, featuring a low rigidity area and a hook tape for secure engagement without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rectangular absorbent article is used to cover forward-positioned urethral openings, then coverage reliability is improved, but the article cannot be fixed in a folded or wrapped state requiring additional members
Solution Approach 1:
The locking member is integrated into the absorbent article structure itself, specifically formed from the back surface layer material, rather than being a separate component. This merging of the locking function into the existing structure allows the article to maintain a folded state without adding separate members, resolving the contradiction between reliability and device complexity
Solution Approach 2:
The absorbent article locks itself in the folded state through the locking member that engages with the low rigidity area of the back surface layer. The structure is self-contained and does not require external fastening mechanisms or additional components to maintain its compact form, enabling the article to serve its own containment needs
2Stability of the object's composition
If additional members are provided to fix the folded state, then shape stability is improved, but manufacturing cost increases
Solution Approach 1:
The locking member is formed as an integral part of the back surface layer through embossing or molding during the existing manufacturing process, eliminating the need for separate components. This integration maintains shape stability while avoiding additional manufacturing steps and material costs
Solution Approach 2:
The back surface layer is designed with a low rigidity area that has different physical properties (lower stiffness) compared to the rest of the layer. This parameter change allows the locking member to engage and hold the folded state effectively without requiring additional rigid components, maintaining shape stability while using existing material properties

AI summary
An absorbent article for pets includes a front surface layer, a back surface layer, and an absorbent body, and is formed in a rectangular shape having a first end portion, a second end portion, and a pair of side portions. The first end portion is arranged on the body of the pet, and the second end portion side is detachably attached to the outer surface of the first end portion when worn. The absorbent article further includes an engaging member arranged on the outer surface side of the first end portion, and is engageable with the inner surface of the second end portion. A part of the outer surface of the back surface layer is formed from a member engageable with the engaging member. A low rigidity area is formed towards the second end portion side of the section on the first end portion where the engaging member is arranged.
