Segmented Wearable Defibrillator Case Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable defibrillators lack durability and usability, posing risks due to potential damage from impacts and the need for timely application during acute arrhythmic emergencies, with existing devices often being impractical for long-term use outside a hospital setting.
Innovation Solution
A multi-part removable case for wearable medical devices, featuring a first part and second part connected to form a parting line around the external housing, with locking mechanisms and a tool for secure attachment and detachment, ensuring durability and ease of use while preventing accidental removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable defibrillator is made compact and portable, then it can be worn by patients for long-term use outside hospital, but it lacks durability and may be damaged from impacts
Solution Approach 1:
The case is divided into multiple separable parts (first part and second part) that can be assembled around the device. This segmentation allows the case to be designed with optimized protection features in each section while maintaining overall portability, and enables easy replacement or repair of individual parts without compromising the entire structure.
2Strength
If the case is made secure and durable with locking mechanisms, then it protects the device from damage, but it may prevent timely removal during acute arrhythmic emergencies
Solution Approach 1:
The case is segmented into multiple parts that can be independently removed or accessed. During emergencies, users can quickly access critical components or remove specific sections without having to dismantle the entire case, thus maintaining security during normal use while enabling rapid access when needed.
Solution Approach 2:
The locking mechanisms are designed with dynamic characteristics, allowing them to be securely locked during normal operation but quickly released when needed. The system transitions between locked and unlocked states efficiently, ensuring both security and rapid accessibility during critical situations.
3Strength
If the case is made as a single integrated piece, then it provides continuous protection, but it cannot be easily replaced or repaired
Solution Approach 1:
The case is divided into multiple replaceable parts that can be independently removed, inspected, and replaced. This segmentation maintains continuous protection when assembled while enabling easy repair or replacement of individual components, extending the overall lifespan and maintainability of the device.
Solution Approach 2:
The segmented case design allows individual parts to be discarded or replaced when worn or damaged, while the remaining parts continue to function. This enables selective replacement of only the necessary components rather than replacing the entire case, improving ease of repair and reducing waste.
