Flexible Sensing Panel Edge Protection for Hygiene Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for reusable hygiene monitoring devices that are cost-efficient, robust, and provide comfort while monitoring the hygienic state of users without direct contact, especially for absorbent hygiene articles, to minimize waste and cumbersome cleaning efforts.
Innovation Solution
A flexible sensing panel with a protective layer and fastening means layer is used, where the protective layer is folded over the edges of the substrate to prevent damage, create a soft and non-abrasive surface, and prevent entry of undesired substances, while the fastening layer ensures secure attachment without exposing the edges, using a flexible substrate with sensing elements for monitoring body fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective layer is added to protect the flexible substrate and sensing elements, then the durability and protection against wear is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
A flexible protective layer is applied over the flexible substrate and sensing elements. This thin film structure provides protection against wear and damage while maintaining the flexibility required for the hygiene monitoring device to conform to the absorbent hygiene article surface.
Solution Approach 2:
The sensing panel uses a composite structure combining a flexible substrate, protective layer, and fastening means layer. This composite approach integrates multiple functions (support, protection, and attachment) into a single multi-layer structure, improving reliability while managing complexity through functional integration.
2Stability of the object's composition
If the protective layer is folded over the edges of the flexible substrate, then the robustness and prevention of permanent creases is improved, but the manufacturing complexity and time increase
Solution Approach 1:
The protective layer is folded over the edges of the flexible substrate, creating a curved or rounded edge profile. This curvature prevents sharp edges from creating permanent creases in the flexible substrate during bending and flexing operations, maintaining structural stability over repeated use.
Solution Approach 2:
The protective layer is folded over the edges during the manufacturing process, creating a pre-formed protective edge structure before the device is put into service. This preliminary action ensures that the edges are already protected against crease formation when the device is subsequently bent and used.
3Ease of operation
If the protective layer is folded over the edges, then the comfort and softness of the device surface is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The protective layer is folded over only the edges of the flexible substrate, while the central area remains flat and functional. This localized folding provides comfort and softness at the edges where contact with the user's skin occurs, without affecting the precision requirements for the sensing element areas.
Solution Approach 2:
The folded protective layer creates a curved, rounded edge profile that feels soft and comfortable against the skin. The curvature distributes pressure and creates a more pleasant tactile sensation, improving comfort without requiring high manufacturing precision in the sensing element areas.
4Object-affected harmful factors
If the protective layer is folded over the edges, then the prevention of substance entry is improved, but the device complexity increases
Solution Approach 1:
The protective layer folded over the edges creates a flexible barrier that prevents body fluids and contaminants from penetrating into the sensing panel structure. This thin film barrier maintains flexibility while providing effective protection against harmful substances.
Solution Approach 2:
The protective layer is nested over the edges of the flexible substrate, creating a layered structure where the protective layer envelops the sensing elements and substrate edges. This nested configuration provides comprehensive protection against substance entry while maintaining a compact overall structure.

AI summary
A flexible sensing panel includes a flexible substrate having first and second major surfaces, first and second separated side edges, and first and second ends, the flexible substrate being at least partly disposed between a flexible protective layer and a flexible fastening layer, and at least one sensing element being disposed on the flexible substrate. The protective layer is secured to the first major surface of the flexible substrate and is folded over the first and second side edges onto the second major surface of the flexible substrate and secured thereto to position at least part of the first and second side edges within the so formed folds, and wherein the fastening layer is at least partly disposed on the second major surface of the flexible substrate and secured thereto.
