Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adult diapers are excessively large, leading to side leaking, wasteful material usage, and environmental concerns, particularly for female and male users, and individuals requiring long-term bed lying, due to inadequate fit and design that causes immersion of external sex organs in feces, urinary tract infections, and inefficient urine collection.
Innovation Solution
An absorbent article with a liquid permeable top layer, liquid impermeable bottom layer, and absorbent core, featuring easy tear line openings and hook-and-loop fasteners for secure fitting with enclosing pants, reducing material waste, preventing side leaking, and allowing for easy installation and ventilation, while accommodating urine tubes and sacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a full-coverage diaper is used to ensure complete body coverage, then absorption capacity is improved, but material waste increases and side leaking occurs due to poor fit
Solution Approach 1:
The diaper is divided into distinct functional zones: a rear pad with absorbent core for waste absorption, and optional front pad components that can be selectively attached or omitted. This segmentation allows the absorbent materials to be concentrated where needed (rear section) while reducing or eliminating material in areas where it is unnecessary (front belly section for females, or entire front section for urine tube users), thus resolving the contradiction between ensuring adequate absorption capacity and reducing material waste.
2Quantity of substance
If a full-coverage diaper is used to ensure complete body coverage, then absorption capacity is improved, but side leaking occurs due to poor fit
Solution Approach 1:
The diaper design applies local quality by providing high absorbency and full coverage in the rear pad section where fecal matter is generated, while using minimal or no material in the front belly section where it is not needed. The rear pad extends sufficiently to cover the gluteal region and prevent side leaking, while the optional front pad can be attached only when required (for females needing belly coverage) or omitted entirely (for urine tube users), thus achieving reliable side leaking prevention without unnecessary material in inappropriate areas.
3Adaptability or versatility
If a large-sized diaper is used to accommodate various body sizes, then versatility is improved, but fit precision deteriorates leading to side leaking
Solution Approach 1:
The diaper is segmented into a mandatory rear pad section and an optional front pad section. The rear pad is designed with standardized dimensions that provide adequate coverage for all users, ensuring consistent fit precision in the critical absorption zone. The front pad, when used, can be selected and attached based on individual needs (female belly coverage vs. urine tube accommodation), allowing versatility in sizing and configuration while maintaining precise fit where it matters most (rear section).
Solution Approach 2:
The diaper design incorporates dynamic adaptability through optional front pad attachment and easy-tear lines that allow the front section to be selectively opened or closed. This dynamic configuration enables the same diaper structure to adapt to different user needs and body types, maintaining fit precision in the rear absorption zone while providing flexibility in front section coverage, thus resolving the contradiction between versatility and fit precision.
4Object-affected harmful factors
If the front belly section is kept closed to maintain coverage, then protection is improved, but ventilation deteriorates causing Stuffing and high temperature
Solution Approach 1:
The front belly section incorporates easy-tear lines that enable dynamic opening and closing of the front pad. When ventilation is needed, users can tear open the front section to allow air circulation and reduce Stuffing and temperature. When protection is prioritized, the front section can be kept closed. This dynamic configurability resolves the contradiction between protection from soiling and ventilation by allowing users to adjust the front section state based on immediate needs.
5Quantity of substance
If the diaper is made large and heavy to ensure coverage, then absorption capacity is improved, but handling burden increases for caregivers
Solution Approach 1:
The diaper is segmented into a rear pad with absorbent core and an optional front pad. The rear pad contains the necessary absorbent materials to ensure adequate absorption capacity for fecal matter. The front pad, which adds significant weight and bulk, is made optional and can be attached only when needed (for female belly coverage) or omitted entirely (for urine tube users or when ventilation is prioritized). This segmentation reduces the default weight of the diaper while maintaining sufficient absorption capacity in the critical rear section, thus resolving the contradiction between absorption capacity and handling burden.

AI summary
An absorbent article and enclosing pants and a method for wearing the combination thereof are provided. The absorbent article has a front lifting section and a rear lifting section that are provided with apertures to allow male and female parts of hook-and-loop fasteners of the enclosing pants to touch inside the apertures and to engage outside the apertures for preventing skidding. An isolating absorbent article may have an easy tear line opening for selectively tearing and tightly surrounding around a rear root portion of the scrotum to isolate the external sex organ and for installation or extension of a urine tube or a urine sack. The enclosing pants has the front pad and a rear pad having two lifting and looping sections and a central opening section, the central opening for fixing and correspond the easy tear line opening.
