Nursing Garment Clasp Assembly for Smooth Pump Layer Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nursing garments for breast pumps often suffer from issues such as discomfort and inconvenience due to interference between small fasteners, leading to difficult detachment and connection, and the need for manual holding of the breast shield, restricting the mother's ability to perform other tasks.
Innovation Solution
A nursing garment with a clasp assembly comprising a shoulder strap, a first clasp with a hook and slot, an inner layer with an opening for the breast pump or nipple exposure, and an outer layer with a third clasp that removably attaches to the first hook, ensuring smooth detachment and connection by positioning clasps to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small-sized fasteners are used in the nursing garment design, then the garment structure becomes more compact, but the fasteners interfere with each other causing discomfort and difficult detachment
Solution Approach 1:
The clasp assembly is divided into multiple independent components: a first clasp with hook and slot, a second clasp with hook, and a third clasp with slot. This segmentation allows each component to be positioned separately, eliminating interference between fasteners while maintaining a compact overall structure.
Solution Approach 2:
The clasps are arranged in different spatial dimensions and positions on the garment layers. The first clasp is on the shoulder strap, the second clasp is on the inner layer, and the third clasp is on the outer layer, distributing fasteners across multiple dimensions to avoid interference.
2Shape
If multiple fasteners are positioned close together, then the garment maintains a compact design, but the fasteners press against the body causing discomfort
Solution Approach 1:
Different regions of the garment are designed with different fastening characteristics. The first clasp uses a hook-slot mechanism on the shoulder strap, while the second and third clasps use hook mechanisms on the inner and outer layers respectively. This local differentiation allows optimal positioning that avoids body pressure points.
Solution Approach 2:
Fasteners are distributed across multiple layers (shoulder strap, inner layer, outer layer) rather than being concentrated in one area, spreading the structural elements across different spatial dimensions to reduce localized pressure on the body.
3Device complexity
If the inner and outer layers are designed with simple fastening, then the garment structure is simplified, but the detachment and attachment process becomes unsmooth
Solution Approach 1:
The fastening system is segmented into multiple independent clasp mechanisms rather than using a single complex fastener. Each clasp (first, second, and third) operates independently with simple hook or slot structures, making the overall system both simple and smooth-operating.
Solution Approach 2:
The slot structures act as intermediaries that guide the hook structures during attachment and detachment. The first slot on the first clasp works with the second clasp's hook, and the third clasp's slot works with the first hook, creating smooth mechanical guidance that facilitates easy operation.

AI summary
The present application discloses a nursing garment comprising: shoulder strap; a first clasp connected to the shoulder strap, the first clasp having a first hook and a first slot; an inner layer with an opening configured to support part of a breast pump inserted into the opening, or to allow a user's nipple to be exposed for breastfeeding; a second clasp connected to the inner layer, configured to removably connect the inner layer to the first slot; and an outer layer with a third clasp connected to it, the third clasp configured to detachably connect the outer layer to the first hook.
