Hinged Alignment Sleeve for Ostomy Sensor Patch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy appliances face challenges with adhesive failure leading to leakage incidents, which are embarrassing and stigmatizing, and often occur suddenly, reducing the quality of life for ostomists. Current solutions do not provide reliable guidance for users to react to impending or actual adhesive failure.
Innovation Solution
An alignment aid comprising a sleeve with a first sleeve section and a second sleeve section connected by a hinge, allowing precise alignment and transfer of a sensor patch onto a base plate for an ostomy appliance. The alignment aid facilitates correct orientation and attachment of the sensor patch to the base plate, ensuring proper adhesion and reducing the risk of leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sensor patch is manually aligned and attached to a base plate, then the attachment process is simple, but the alignment precision is insufficient leading to leakage incidents
Solution Approach 1:
The alignment aid acts as an intermediary device between the sensor patch and base plate. It includes a first sleeve section for securing the sensor patch and a second sleeve section for securing the base plate, with a hinge connecting them. This intermediary structure enables precise alignment through mechanical guidance while maintaining a relatively simple attachment process.
Solution Approach 2:
The alignment aid is divided into multiple functional segments: a first sleeve section for the sensor patch, a second sleeve section for the base plate, and a hinge connecting them. This segmentation allows each component to perform its specific function independently while working together to achieve precise alignment, resolving the contradiction between precision and complexity.
2Reliability
If adhesive materials are used to attach the base plate to skin, then the attachment is initially strong, but adhesive failure occurs over time due to moisture and body fluids
Solution Approach 1:
The sensor patch attached through the alignment aid provides feedback capability to monitor the condition of the adhesive attachment over time. This allows detection of early signs of adhesive degradation before complete failure occurs, enabling timely intervention to maintain reliability while extending effective wear time.
3Stability of the object's composition
If hydrocolloid materials are added to absorb moisture, then the adhesive stability is improved, but the device complexity increases
Solution Approach 1:
The moisture absorption function is extracted from the adhesive composition itself and implemented through a separate mechanical structure - the alignment aid with its sleeve sections. This allows the adhesive to maintain its original simple composition while the alignment aid structure provides the moisture management capability, resolving the contradiction between stability and complexity.

AI summary
An alignment aid for aligning a sensor patch (20) on a base plate (30) for an ostomy appliance, the alignment aid facilitates easy and precise alignment of the sensor patch on the base plate. The alignment aid comprises a sleeve (10) having a first surface comprising a first sleeve section (40) and a second sleeve section (50), the first sleeve section and the second sleeve section being connected along a connection line (60), said connection line defining a hinge enabling the first sleeve section to pivot and superimpose the second sleeve section. The first sleeve section is configured to secure the proximal side of sensor patch and the second sleeve section is configured to secure the distal side base plate. When the first sleeve section is pivoted to overly the second sleeve section, the sensor patch is transferred to the proximal surface of the base plate.
