Infusion Pump Charging Cover for Stable Inductive Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambulatory infusion pumps face challenges in efficient and stable inductive charging due to misalignment and accidental dislodging during charging, which can affect battery charging efficiency and reliability.
Innovation Solution
A cover with a cutout and engagement mechanism is designed to fit the ambulatory infusion pump, ensuring optimal alignment and secure retention on an inductive charging device, using clips and anti-rotation features to prevent movement and enhance charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover with cutout and engagement mechanism is added to the inductive charging device, then alignment stability and prevention of accidental dislodging are improved, but device complexity increases
Solution Approach 1:
A cover is introduced as an intermediary component between the inductive charging device and the infusion pump. The cover includes a cutout that receives the pump and engagement mechanisms (clips, tabs, or latches) that secure the pump in place, preventing accidental dislodging while maintaining inductive charging functionality.
Solution Approach 2:
The cover is designed as a separate, removable component rather than integrating the retention features directly into the charging device body. This segmentation allows the cover to be optimized for both alignment and retention functions while keeping the main charging device structure simpler.
2Reliability
If the pump is securely retained on the charging device, then charging reliability is improved, but ease of operation for removing and repositioning the pump deteriorates
Solution Approach 1:
The engagement mechanisms are designed to provide secure retention during charging while allowing easy release when needed. Clips can be spring-loaded or friction-based to hold the pump firmly but release with gentle pressure, and latches can be manually actuated to quickly release the pump for removal or repositioning.
Solution Approach 2:
The cover and engagement mechanisms are designed to automatically engage and disengage the pump without requiring additional tools or complex operations. The pump can be simply placed into the cover cutout for automatic engagement, and removed by applying minimal force to the release mechanism.
