Cantilevered Mounting Module for Wearable Injector Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable injectors often transfer motor vibration and noise to the user, which can be bothersome, and reducing motor speed or using costly noise-reducing motors are not optimal solutions.
Innovation Solution
A noise and vibration mounting module with a cantilevered mounting arm and vibration-reducing pads that independently secures within the injector housing, absorbing and dampening vibrations before they reach the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If motor speed is reduced to reduce vibration and noise, then noise and vibration are reduced, but delivery rates are restricted
Solution Approach 1:
The patent extracts the harmful vibration and noise from the motor assembly by introducing a mounting module with vibration-absorbing elements that isolate the motor from the injector housing, allowing the motor to operate at high speeds without transferring harmful vibrations to the user or restricting delivery rates
2Object-affected harmful factors
If specialized noise and vibration reducing motor components are used, then noise and vibration are reduced, but cost increases
Solution Approach 1:
The patent introduces a mounting module as an intermediary component between the motor and the injector housing. This module contains vibration-absorbing elements that reduce noise and vibration without requiring expensive specialized motor components, thereby maintaining cost-effectiveness while achieving the desired noise and vibration reduction
Solution Approach 2:
The mounting module employs composite construction combining rigid mounting arms with vibration-absorbing materials, creating a composite structure that provides both mechanical support and noise/vibration reduction functionality at a lower cost than specialized motor components
3Device complexity
If motor is mounted directly to injector chassis, then structural simplicity is maintained, but vibration and noise are transferred to user
Solution Approach 1:
The patent segments the motor mounting function from the main injector structure by introducing a separate mounting module. This module can be selectively secured to the injector housing, providing vibration isolation while maintaining relatively simple overall structure through modular design

Function Achieved in This Case
Effectively reduces motor vibration and associated noise, allowing for higher delivery rates without increasing costs by isolating the actuator from the injector housing.

AI summary
An independent mounting module is receivable within a housing of an injector configured to dispense a substance from a cartridge insertable into the housing through an injection needle of the injector. The mounting module includes a first mount and a second mount. The first mount is configured to receive a driving assembly engageable with the cartridge to expel the substance therefrom. The first mount is selectively securable to the injector housing and has a cantilevered mounting arm extending therefrom. The second mount is configured to receive an actuator operatively connectable with the driving assembly. The second mount is attached to the cantilevered mounting arm and suspended therefrom, thereby being supported by the cantilevered mounting arm.
