Pet Diaper Tail Hole Positioning for Gender Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet diapers fail to fit appropriately based on the gender of the pet due to difficulties in positioning the absorbent and tail through-hole according to the pet's anatomy, as the urethral opening's location differs between males and females.
Innovation Solution
A pet diaper design featuring a back portion, abdominal portion, and crotch portion with specific cut portions and easily-incised areas, including first and second cut portions and easily-incised portions, allows for adjustable tail through-holes to accommodate male and female pets by positioning the absorbent layer effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed tail through-hole position is used in the pet diaper, then the diaper structure is simple and easy to manufacture, but the diaper cannot be properly positioned for both male and female pets due to different urethral opening locations
Solution Approach 1:
The tail through-hole area is segmented into multiple candidate positions (first tail through-hole position and second tail through-hole position) along the longitudinal direction. This segmentation allows the diaper to be adapted to different pet genders by selecting the appropriate position, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The diaper structure incorporates dynamic adjustability by providing multiple tail through-hole positions that can be selected based on the pet's gender. This dynamic configuration enables the same diaper design to accommodate both male and female pets effectively.
2Reliability
If the absorbent body is positioned anteriorly to maximize coverage for male pets, then urine absorption from the genital tip is improved, but the crotch portion cannot be positioned posteriorly to effectively capture urine from female pets' urethral openings
Solution Approach 1:
The absorbent body is segmented into multiple regions with different absorption characteristics. The first absorbent region is positioned anteriorly to handle male pet urine, while the second absorbent region extends posteriorly to capture female pet urine, allowing the single absorbent body to serve both gender types effectively.
Solution Approach 2:
Different regions of the absorbent body have different properties and positions optimized for specific functions. The anterior region is positioned for male pet coverage while the posterior extension provides female pet coverage, creating local quality variations that enhance overall adaptability and reliability.
3Ease of operation
If perforations are made throughout the entire annular portion and division portion, then the tail through-hole can be formed at any position, but it becomes difficult to control the precise positioning of the absorbent body relative to the pet's anatomy
Solution Approach 1:
The perforation pattern is segmented into different zones: a first perforation region and a second perforation region. This segmentation allows flexible tail through-hole formation in the first region while maintaining precise absorbent body positioning control through the structured second region with specific incised and non-incised portions.
Solution Approach 2:
The diaper is pre-configured with specific incised and non-incised portions in the second perforation region to guide proper positioning. This preliminary action ensures that when the tail through-hole is formed, the absorbent body automatically aligns with the correct position relative to the pet's anatomy.

Function Achieved in This Case
Enables the pet diaper to be fitted appropriately for both male and female pets, reducing urine leakage and allowing for proper excretion of feces by adjusting the tail through-hole size based on the pet's gender, ensuring effective absorption and excretion.

AI summary
A pet diaper is equipped with a front surface layer, a back surface layer, and an absorbent layer disposed between the front surface layer and the back surface layer. The pet diaper has a back portion, an abdominal portion, and a crotch portion disposed between the back portion and the abdominal portion. The pet diaper is further equipped with: a first cut portion that is provided on the back portion and that is formed as a convex curve rounding towards the end portion of the back portion; a second cut portion that is provided closer to the crotch portion than the first cut portion and that is formed as a convex curve rounding towards the end portion of the back portion; and a first perforated portion that is formed so as to extend from the second cut portion towards the first cut portion.
