Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing incontinence monitoring systems for absorbent hygiene articles suffer from inaccurate sensing, false positives and negatives, environmental sustainability issues, and user discomfort due to invasive sensor placement and maintenance requirements.
Innovation Solution
A strip element with close contact sensing zones and a flex zone that allows for external attachment to absorbent hygiene articles, featuring mechanical attachment means and a deformation susceptibility zone to prevent measurement errors and promote comfort, enabling reusable and easy-to-clean design without integrating electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is placed close to the skin for accurate detection, then measurement precision is improved, but user comfort deteriorates due to pressure marks and skin irritations
Solution Approach 1:
The patent introduces an intermediary flexible zone between the sensing elements and the skin surface. This flexible zone acts as a mediator that allows the sensor to maintain close proximity for accurate detection while preventing direct pressure contact with the skin, thereby eliminating skin irritation and pressure marks.
2Measurement precision
If the sensor is integrated into the absorbent article for accurate monitoring, then measurement precision is improved, but device complexity increases requiring special tools and customized articles
Solution Approach 1:
The patent segments the monitoring system into a separate removable strip element that can be independently attached to standard absorbent articles. This segmentation eliminates the need for integrating sensors into the absorbent core, allowing use with conventional articles and removing the requirement for special application tools while maintaining monitoring accuracy.
3Measurement precision
If direct contact between sensor and excretion is established for detection, then measurement precision is improved, but hygiene maintenance requirements increase requiring periodic cleaning and replacement
Solution Approach 1:
The patent introduces an intermediary absorbent layer between the sensing elements and the excretion. This layer allows the sensor to detect excretion events through the absorbent material without direct contact, thereby maintaining detection accuracy while eliminating the need for periodic cleaning and replacement of the sensor for hygienic reasons.
4Measurement precision
If the strip element is firmly attached to the absorbent article for stable sensing, then measurement precision is improved, but user comfort deteriorates under external forces causing discomfort
Solution Approach 1:
The patent implements a dynamic attachment system where the flexible zone can adapt its attachment characteristics in response to external forces. The flexible zone maintains stable sensing conditions during normal wear while allowing controlled detachment or movement under higher external forces, thereby preventing discomfort while preserving measurement precision.

AI summary
Disclosed is a strip element configured to be externally and removably provided to an absorbent hygiene article, the strip element comprising at least two sensing elements for obtaining excretion-related information in the absorbent hygiene article, at least two close contact sensing zones for being removably attached to a garment facing surface of the absorbent hygiene article, respectively, and each comprising one of the at least two sensing elements, wherein, each close contact sensing zone includes first attachment means for keeping the close contact sensing zone in contact with the absorbent hygiene article by a first attachment force, the two close contact sensing zones being separated by a flex zone which is either free of any attachment means or includes second attachment means for establishing a second attachment force between the flex zone and the absorbent hygiene article, the second attachment force being a smaller force than the first contact force.
