Ostomy Appliance Modular Cap Wafer Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy devices lack a seamless integration of caps and wafers, leading to complex and costly production, limited user options, and increased user effort in attaching separate components, which can be cumbersome for individuals with poor motor skills or preferences for specific components.
Innovation Solution
An ostomy appliance system that couples a cap to an ostomy wafer through an adaptable mechanism, allowing for temporary or permanent attachment, with a sealing system to prevent gas and waste leakage, and incorporating a flushing mechanism for hygiene and irrigation, enabling the use of uncoordinated cap and wafer designs for reduced production costs and enhanced user convenience.

Engineering Contradiction Analysis
1Adaptability or versatility
If separate cap and wafer components are used in existing ostomy devices, then users have limited options and production is complex and costly, but this also increases user effort in attaching components and is cumbersome for individuals with poor motor skills
Solution Approach 1:
The ostomy device is divided into separate functional modules: a wafer module with adhesive skin barrier and a cap module with pouch attachment. These modular components can be independently manufactured, selected, and attached, providing users with options while simplifying production through standardized interfaces.
Solution Approach 2:
The ostomy device is designed with universal attachment mechanisms that allow different cap designs to be compatible with different wafer designs. The standardized interface enables one wafer to work with multiple cap types and vice versa, expanding user options without proportionally increasing production complexity.
2Ease of manufacture
If separate cap and wafer components are used in existing ostomy devices, then production costs increase, but this also increases user effort in attaching components
Solution Approach 1:
The wafer and cap components are pre-assembled with their respective attachment mechanisms during manufacturing. The adhesive layer is pre-applied to the wafer and the pouch attachment mechanism is pre-installed on the cap, eliminating the need for users to perform complex assembly operations and reducing attachment effort.
Solution Approach 2:
A standardized interface mechanism serves as an intermediary between the wafer and cap components. This intermediate attachment system simplifies the user's task by providing a clear, intuitive connection method while allowing flexible component selection and independent manufacturing.
3Adaptability or versatility
If existing ostomy devices lack seamless integration of caps and wafers, then production is complex and costly, but this also limits user options and increases attachment effort
Solution Approach 1:
The device utilizes parameter standardization in the attachment interface, allowing different components with varying parameters (size, shape, material) to be compatible through standardized connection parameters. This enables seamless integration of diverse cap and wafer designs without increasing overall system complexity.
