Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorized breast pumps generate high levels of noise and vibration, disrupting the natural ambiance needed for efficient milk expression and making it difficult for women to use them discreetly outside the home.
Innovation Solution
A motorized head for a breast pump featuring a resiliently deformable member that connects the motor mounting portion to the body mounting portion, reducing vibration transfer and incorporating a sinuous form with raised portions to minimize contact area and enhance acoustic damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a motor and drive mechanism are used to automate breast pump operation, then pumping efficiency and productivity are improved, but noise level and vibration increase
Solution Approach 1:
A resiliently deformable member is introduced as an intermediary element between the motor mounting portion and the body mounting portion. This mediator absorbs and dampens vibrations generated by the motor and drive mechanism, preventing them from being transmitted to the breast pump body and reducing noise levels while maintaining pumping efficiency
Solution Approach 2:
The resiliently deformable member changes the mechanical parameters of the connection between mounting portions by introducing elasticity and compliance. This parameter change allows the system to maintain the benefits of motorized automation while reducing harmful vibrations and noise through the deformable connection
2Productivity
If a motor and drive mechanism are used to automate breast pump operation, then pumping efficiency and productivity are improved, but vibration transfer to the breast pump body increases
Solution Approach 1:
The resiliently deformable member serves as a vibration-isolating intermediary between the motor mounting portion and the body mounting portion. It absorbs and dampens vibrations, preventing their direct transmission to the breast pump body and maintaining operational stability
Solution Approach 2:
By introducing the resiliently deformable member, the mechanical connection parameters are changed to include vibration-damping properties. This allows the motorized system to operate efficiently while the deformable member absorbs and dissipates vibrations before they reach the pump body
3Productivity
If conventional motorised breast pumps are used, then milk expression can be achieved, but the natural ambiance is disrupted and comfort is reduced
Solution Approach 1:
The resiliently deformable member acts as a mediator that isolates the user from the mechanical vibrations and noise generated by the motorized pump. This allows the pump to maintain its milk expression functionality while creating a more comfortable and natural ambiance for the user
