Solution Overview
Problem
Current breast pumps often cause discomfort and injuries due to their suction-only mechanisms, which do not mimic the natural suckling patterns of infants, leading to adverse side effects such as nipple soreness and lactation complications, and result in early termination of breastfeeding.
Innovation Solution
A bio-inspired breast pump system that replicates infant suckling patterns using soft pneumatic actuators and piezoelectric sensors, providing adjustable vacuum and compression pressures, temperature control, and AI-controlled milk extraction to optimize comfort and milk yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction-only mechanisms are used in breast pumps, then milk extraction function is achieved, but user comfort and safety deteriorate causing nipple soreness and lactation complications
Solution Approach 1:
The breast pump system segments the milk extraction process into distinct phases: compression phase (mimicking infant jaw pressure), relaxation phase (mimicking infant tongue movement), and suction phase (mimicking infant vacuum). This segmentation allows each phase to be optimized independently, achieving effective milk extraction while preventing tissue damage through proper timing and pressure control.
Solution Approach 2:
The system employs periodic cyclic operation with alternating compression and suction phases, replicating the natural rhythmic suckling pattern of infants. This periodic action prevents continuous suction damage by incorporating relaxation intervals, thereby reducing nipple soreness and lactation complications while maintaining effective milk transfer.
2Speed
If continuous suction is applied, then milk extraction speed is improved, but user comfort deteriorates causing adverse side effects
Solution Approach 1:
The system uses periodic cyclic operation with alternating compression and suction phases, replicating the natural rhythmic suckling pattern of infants. This periodic action prevents continuous suction damage by incorporating relaxation intervals, thereby reducing nipple soreness and lactation complications while maintaining effective milk transfer.
Solution Approach 2:
The breast pump system dynamically adjusts pressure parameters and timing based on detected milk flow rates and user feedback. The compression force, suction pressure, and phase durations are continuously optimized to maximize milk extraction speed while preventing tissue damage, adapting to different breastfeeding stages and individual user needs.
3Productivity
If compression and vacuum pressures are coordinated, then milk transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The system merges compression and vacuum functions into a single integrated breast pump device with coordinated control. The compression rollers and vacuum pump operate synchronously under unified control, achieving effective milk transfer without requiring multiple separate devices. This integration manages complexity through shared control architecture and coordinated timing mechanisms.
Solution Approach 2:
The system incorporates sensors that detect milk flow rates and provide real-time feedback to the control system. This feedback enables automatic adjustment of compression force and suction pressure to optimize milk transfer efficiency. The closed-loop control compensates for variations in breast tissue properties and milk flow characteristics, maintaining optimal performance without requiring complex manual calibration.
