Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of sanitary napkins are purchased to accommodate varying flow levels and body shapes, then fit and protection are improved, but cost and environmental waste increase
Solution Approach 1:
The patent applies universality by designing a single sanitary napkin that can serve multiple functions through adjustable components. The napkin includes detachable wings and adjustable absorbent sections that allow one product to accommodate various flow levels (light, moderate, heavy) and body shapes, replacing the need for multiple specialized pads
Solution Approach 2:
The patent applies segmentation by dividing the sanitary napkin into detachable components including wings and absorbent sections. These segmented parts can be removed or adjusted independently, allowing customization of the napkin's size, shape, and absorbency level to match individual needs while using a single base product
2Adaptability or versatility
If pads are cut to desired size and shape using scissors, then fit is improved, but pad integrity and effectiveness are compromised
Solution Approach 1:
Instead of cutting the pad which compromises integrity, the patent uses pre-segmented detachable wings and absorbent sections connected by perforated seams. Users can remove entire sections rather than cutting through absorbent material, maintaining pad integrity while achieving custom fit
Solution Approach 2:
The patent transforms the static fixed-size pad into a dynamic adjustable structure. The detachable components allow the pad's dimensions and absorbency to be dynamically adjusted by removing or keeping specific sections, enabling customization without damaging the pad's structural integrity
3Ease of manufacture
If fixed-size pads are used, then manufacturing simplicity is maintained, but user comfort and optimal fit are reduced
Solution Approach 1:
The patent introduces segmentation with detachable wings and absorbent sections connected by perforated seams. This allows the base pad to be manufactured simply while adding modular components that enable users to customize fit and absorbency, balancing manufacturing ease with user comfort
Solution Approach 2:
The patent applies preliminary action by pre-configuring detachable components and perforated seams during manufacturing. This prepares the pad for easy user adjustment without requiring complex manufacturing processes, as the segmentation and attachment mechanisms are built in advance

AI summary
The present invention discloses a multi-functional sanitary napkin designed for customizable menstrual protection. It features a base pad with multiple absorbent layers and a moisture-proof backing for optimal absorption and leak prevention. Removable absorbent sections within the base pad allow users to adjust absorbency by peeling off or detaching sections, each interlocking with adjacent sections to maintain integrity. The napkin includes detachable wings, attached via a perforated seam or snap system, for user preference without compromising structure. Adjustable length and width are achieved through foldable or detachable sections and side panels, secured with fastening mechanisms like Velcro, snaps, or adhesive strips. Re-sealable edges prevent leaks and ensure pad integrity after adjustments. This design prioritizes user comfort, customization, and leak protection, accommodating various needs throughout the menstrual cycle.
