Solution Overview
Problem
Patch pumps and other electrically operated drug delivery devices experience vibration and noise during operation, which can be uncomfortable for users and disruptive, necessitating a solution to minimize these issues without compromising device functionality.
Innovation Solution
Incorporating a noise reducing component, such as a vibration and/or noise dampening material, between the mechanical components and the base or housing of the delivery device to absorb and dampen vibrations and noise, thereby reducing their transfer to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If mechanical components are used for drug delivery, then delivery functionality is achieved, but vibration and noise are generated
Solution Approach 1:
A noise reducing component is introduced as an intermediary element between the mechanical components and the device housing. This component absorbs and dampens vibrations and noise generated by the mechanical components, preventing their direct transmission to the housing and reducing the harmful effects perceived by the user.
Solution Approach 2:
The noise reducing component converts the harmful vibrations and noise into beneficial damping effects. By strategically placing materials that dissipate mechanical energy, the system transforms the harmful mechanical vibrations into heat energy through internal friction, thereby reducing the noise and vibration transmission to the user.
2Object-generated harmful factors
If noise reducing component is added, then vibration and noise are minimized, but device complexity increases
Solution Approach 1:
The noise reducing component is designed to serve multiple functions within a single element. It simultaneously provides vibration damping, noise reduction, and structural support, thereby reducing the need for additional separate components and minimizing the increase in device complexity while achieving the desired reduction in harmful vibrations and noise.

AI summary
A delivery device for delivering a medication to a patient includes a catheter with a catheter insertion mechanism, a housing, and a base with a surface for supporting a pump mechanism. A noise dampening member in or on the device inhibits noise and vibrations from the pump mechanism from transferring through the base and housing. The noise dampening member can be an elastomer that is coated on or adhered to the base. The noise dampening member can be molded in or on the base in a suitable location to dampen noise produced by the mechanical component. The noise dampening member can be between the base and the mechanical component or spaced from the mechanical component. The noise dampening member can be molded in a recessed area formed in the base and can have a top face that is recessed, aligned with or project from the top face of the base.
