Belt-Attached Ostomy Bag Change Frame for Hygienic Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy bag changing devices are bulky, uncomfortable, and lack secure disposal bag attachment, leading to hygiene issues and difficulty in changing or emptying bags independently, especially in confined spaces or when mobility is limited.
Innovation Solution
A frame and support structure device that secures a disposal bag in an open configuration, attached to a belt, with a second body section providing counterbalance and comfort, minimizing the risk of spillage and ensuring easy, hygienic disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing ostomy bag changing devices are used, then bag changing is possible, but the devices are bulky and uncomfortable
Solution Approach 1:
The device is divided into separate functional components: a belt-attachable support structure, a frame, and a disposal bag. This segmentation allows the device to be compact when not in use while providing full functionality during operation, resolving the contradiction between ease of operation and device size.
Solution Approach 2:
The device transitions from a two-dimensional flat configuration (when stored) to a three-dimensional operational structure (when deployed). The frame extends outward from the support structure, creating the necessary volume for bag changing only when needed, thus maintaining compactness while enabling ease of operation.
2Ease of operation
If existing ostomy bag changing devices are used, then bag changing is possible, but they lack secure disposal bag attachment
Solution Approach 1:
The frame includes curved attachment points that conform to the shape of disposal bag handles, creating a secure mechanical connection. This curvature design ensures reliable attachment while maintaining ease of operation during bag changing.
Solution Approach 2:
The frame acts as an intermediary structure between the support structure and the disposal bag. It provides dedicated attachment points that securely hold the disposal bag in place, ensuring reliability while enabling easy operation.
3Ease of operation
If existing ostomy bag changing devices are used, then bag changing is possible, but hygiene issues arise due to lack of secure disposal
Solution Approach 1:
The disposal bag is extracted and securely attached to the frame, separating the waste containment function from the body. This extraction ensures that waste is contained in a dedicated, secure location, preventing contamination while maintaining ease of operation.
Solution Approach 2:
The disposal bag is designed as a single-use component that is securely attached to the frame during use, then removed and disposed of. This disposable approach ensures hygiene by preventing cross-contamination while keeping the device simple and easy to operate.
4Ease of operation
If existing ostomy bag changing devices are used, then bag changing is possible, but independence is compromised in confined spaces
Solution Approach 1:
The device features dynamic components including adjustable straps and flexible frame elements that can adapt to different body sizes and confined spaces. This dynamic design enables independent bag changing in various environments while maintaining ease of operation.
Solution Approach 2:
The device is designed with universal attachment mechanisms that can be used in various locations and with different body types. The belt-attachable support structure and adjustable frame provide multi-functionality, enabling independent use in confined spaces while maintaining ease of operation.
