Neck-Hanging Breast Pump Body with Counterweight Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast pumps are inconvenient to carry due to their design, which often requires users to hold them by hand or wear them in a way that interferes with routine movement and housework.
Innovation Solution
A breast pump body design featuring a neck-hanging structure with two accommodation housings at its ends, one housing part of the air pump and battery, and the other housing the remaining components, allowing the pump to be securely hung around the neck and providing counterweights for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unilateral electric breast pump is used, then the pump can be compact and simple in structure, but it requires hand holding during use which is inconvenient
Solution Approach 1:
The patent transitions the pump from a handheld device to a neck-worn device, utilizing the neck dimension as a new support location. The neck-hanging structure with accommodation housings allows the pump to be positioned on the user's neck, freeing the hands while maintaining a relatively compact form factor.
2Ease of operation
If a wearable T-shaped breast pump is used, then hands-free operation is achieved, but the pump body weight and volume increase causing instability and seal failure
Solution Approach 1:
The patent divides the pump body into two accommodation housings positioned at opposite ends of the neck-hanging structure. This distribution creates a balanced weight configuration that reduces instability and prevents seal failure, while still achieving hands-free operation on the neck.
Solution Approach 2:
The pump body is segmented into two separate accommodation housings that can independently contain components. This segmentation allows for better weight distribution and modular design, improving both stability and ease of assembly while maintaining neck-worn functionality.
3Ease of operation
If the pump body is made portable and wearable, then ease of carrying is improved, but the pump interferes with routine movement and housework
Solution Approach 1:
The neck-hanging structure incorporates flexible elements that allow the pump to adapt to the user's neck contour and movement. The flexible design enables the pump to remain stable during routine activities while allowing natural head and body movements, improving both portability and adaptability.
