Ostomy Waste Bag Support Structure for Extended Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy appliances with larger capacity bags for extended use face challenges in efficiently managing waste collection and support during sleep or extended periods without frequent emptying, particularly in adapting to various support stands and hangers.
Innovation Solution
A waste collection bag design featuring a flexible portion between two attachment zones, allowing for multiple support configurations, including a support system with first and second attachment zones and a flexible portion that enables easy folding and adaptation to different stands or hangers, along with a handle for carrying and hanging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a larger capacity bag is used to extend the time between emptying, then the duration of action is improved, but the device complexity increases due to the need for additional support mechanisms
Solution Approach 1:
The support system is segmented into two distinct attachment zones (first and second attachment zones) with a flexible portion between them, allowing independent attachment to different support structures. This segmentation enables the single bag to adapt to various support stands without increasing overall system complexity.
Solution Approach 2:
The flexible portion between the attachment zones allows the support system to dynamically adapt to different support stand configurations. The flexibility enables the bag to be securely attached whether using one or both attachment zones, accommodating various user needs and support structures without requiring a completely different bag design.
2Duration of action of moving object
If a larger capacity bag is used for extended wear, then the duration of action is improved, but the adaptability to various support stands deteriorates
Solution Approach 1:
The bag is designed with universal adaptability through its dual attachment zone system that can accommodate multiple support stand types. The flexible portion between zones allows the bag to securely attach to different stand configurations, making the same bag design suitable for various support structures while maintaining extended capacity for longer wear duration.
Solution Approach 2:
By dividing the support attachment area into two separate zones connected by a flexible portion, the design enables selective attachment to different support stand configurations. This segmentation provides versatility in adapting to various support stands while maintaining the larger capacity needed for extended wear.
3Strength
If the bag structure is made more rigid to maintain shape, then the strength is improved, but the ease of operation deteriorates due to reduced flexibility in positioning
Solution Approach 1:
The bag exhibits local quality by having different mechanical properties in different regions: the attachment zones provide structural strength and stability for secure attachment, while the flexible portion between zones provides the necessary flexibility for easy positioning and adaptation to different support stands. This localized differentiation of mechanical properties resolves the contradiction between overall strength and operational flexibility.
