Sanitary Article With Tear-Off Wings and Sealed Main Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary articles often require users to choose between versions with or without lateral portions, limiting flexibility and user preference, and existing designs do not allow for easy and intact removal of these portions without disturbing the main body's integrity.
Innovation Solution
The sanitary article features removable lateral wings with tear lines that allow users to detach them from the main body without disrupting the sealed margins, enabling selective detachment and reconfiguration based on user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral portions are made integral to the main body, then structural integrity is maintained, but user flexibility and adaptability are reduced
Solution Approach 1:
The lateral portions are separated from the main body through tear lines, allowing users to detach them as needed. This segmentation enables the sanitary article to be configured with or without lateral portions, providing user flexibility while maintaining structural integrity of the main body when portions are removed.
2Adaptability or versatility
If lateral portions are made removable, then user flexibility is improved, but risk of damaging main body integrity increases
Solution Approach 1:
Tear lines serve as intermediary structures that facilitate controlled separation between lateral portions and the main body. These tear lines are positioned to allow clean detachment while preserving the integrity of the main body's sealed margins, acting as a mediator that enables removal without damage.
Solution Approach 2:
The sanitary article is segmented into removable lateral portions and a main body through strategically placed tear lines. This segmentation allows users to detach portions without compromising the main body's structural integrity, as the tear lines are designed to separate components cleanly at designated locations.
3Ease of manufacture
If sealed margins are maintained, then product reliability is ensured, but ease of modification is reduced
Solution Approach 1:
Lateral portions are extracted from the main body through tear lines that do not intersect with sealed margins. This extraction allows modification of the article (removal or attachment of portions) while preserving the sealed margins' integrity, enabling ease of manufacture and modification without compromising reliability.
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
Provides users with the flexibility to choose and adjust the size and configuration of lateral portions according to their preferences, enhancing comfort and convenience by allowing easy removal and reconfiguration of the sanitary article.
Implementation Method 1
each one of the two lateral wings having an undergarment contacting portion having an adhesive for adhesively contacting the undergarment of a wearer
Implementation Method 2
the respective tear line of each one of the two lateral wings defines an outer lateral wing portion and an inner lateral wing portion, the inner lateral wing portion being positioned between the tear line and the adjacent sealed lateral margin, wherein the respective tear line of each one of the pair of lateral wings provides for both maintaining the outer lateral wing portion attached to inner lateral wing portion when each of the lateral wings is adhesively contacting the undergarment and for detaching the outer lateral wing portion from the inner lateral wing portion when a sufficient tearing force is applied thereto

AI summary
A sanitary article comprises a main body comprising a top and bottom sides and an absorbent core therebetween surrounded and bounded by a core border formed in the top and bottom sides. The top side defines a body contacting surface within the core border. The bottom side defines an undergarment contacting surface within the core border. A main body contour extends beyond the core border and is surrounded and bounded by a sealed main body perimeter defining opposite main body longitudinal ends and opposite main body lateral sides. Each main body lateral side having front and rear portions thereof and a middle portion therebetween. A respective tear line is defined between the inner lateral part of each one of the pair of wings and the middle portion. When a sufficient tearing force is applied to the tear line thereby a wing is fully removed from the main body without physical integrity disturbance of the sealed perimeter at each of the middle portions.
