Thermal Insulating Carrying Case for Implantable Blood Pump Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The external controller for implantable blood pumps is often cumbersome due to the percutaneous driveline, making it unwieldy for users to carry.
Innovation Solution
A carrying case with a flexible pouch designed to retain the controller, featuring thermal insulating and dissipating materials, along with adjustable straps for comfortable wear, and an additional pouch for a Smartphone to prevent electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is carried externally with percutaneous driveline, then the controller can be used to control the implantable blood pump, but the controller becomes unwieldy and cumbersome for users to carry
Solution Approach 1:
The patent combines the controller with a carrying case that integrates multiple functions: thermal management (insulating and dissipating materials), driveline management (pockets and channels), and additional device storage (smartphone pouch). This merging transforms a cumbersome external controller into an organized, manageable system where the carrying case becomes an integral part of the controller assembly, directly addressing the ease of carrying issue.
2Temperature
If thermal management materials are added to the carrying case, then heat buildup is prevented, but the device complexity increases
Solution Approach 1:
The patent applies different thermal properties to different faces of the carrying case: the first face includes thermal insulating material to prevent heat transfer to the user, while the second face includes thermal dissipating material to conduct heat away from the controller. This localized application of different material properties effectively manages heat without requiring the entire case structure to be complex, addressing thermal management needs at specific locations.
3Ease of operation
If multiple pouches and straps are added to the carrying case, then the controller and Smartphone can be organized and carried comfortably, but the manufacturing complexity increases
Solution Approach 1:
The carrying case is designed as a multi-functional system where a single structure serves multiple purposes: the first pouch holds the controller, the second pouch holds the smartphone, the waist strap provides secure attachment and comfortable wear, and the thermal materials provide heat management. This multi-functionality consolidates what would otherwise be separate items into one integrated product, improving ease of operation while managing manufacturing complexity through unified design.
