Ostomy Waste Collection Bag With Flexible Attachment Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy appliances with larger capacity bags for extended use face challenges in efficiently connecting to various support systems and maintaining flexibility for different hanging configurations, limiting user convenience and adaptability.
Innovation Solution
A waste collection bag design featuring a flexible portion between two walls, with distinct attachment zones and a support system that allows for multiple hanging configurations, including a handle for additional support and adaptability to various stands and hangers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a larger capacity bag is used for extended waste collection, then the duration of action is improved, but the device complexity increases due to challenges in connecting to various support systems
Solution Approach 1:
The waste collection bag is designed with multiple attachment zones that can connect to various types of support systems (bed rails, chairs, tables, stands), making the device universal and adaptable to different environments and user needs, thereby resolving the complexity issue while maintaining extended duration capability
2Adaptability or versatility
If the bag is designed for multiple hanging configurations, then the adaptability is improved, but the structural stability may be compromised
Solution Approach 1:
The attachment system is segmented into multiple distinct attachment zones with different configurations (first attachment zone with first configuration, second attachment zone with second configuration), allowing the bag to be segmented and attached in different ways to various support systems while maintaining structural integrity through the flexible portion design
3Reliability
If the walls are connected to form a sealed pouch, then the reliability of waste containment is improved, but the flexibility for different configurations is reduced
Solution Approach 1:
The pouch arrangement has different local qualities: the first and second walls are connected in the lower portion to ensure reliable waste containment, while the upper portion includes a flexible portion where the walls are not connected, providing the necessary flexibility for different hanging configurations and attachment options
