Elastic Bobbin Holding Member for Organized Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bobbin storage solutions, such as thread winding clips and bobbin tidies, face issues with bobbins becoming disorganized and restricting space for storing other sewing machine accessories, as they are either difficult to detach or occupy most of the storage space, limiting the ability to store accessories like scissors and pressers.
Innovation Solution
A bobbin holding member with a C-shaped body made of elastically deformable synthetic resin, featuring fitting portions and target portions for connecting multiple clips, allowing for secure bobbin storage and easy organization, while also enabling the storage of other sewing machine accessories by attaching the clips to a storage case with matching fitting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If thread winding clips are fixed inside the tidy with an adhesive agent to store bobbins in order, then bobbins can be stored in order, but the clips cannot be detached and the space for storing other accessories is restricted
Solution Approach 1:
The invention divides the storage system into separate functional modules: a tidy for storing accessories and a separate bobbin case with holding members for storing bobbins. This segmentation allows each component to be optimized independently - the tidy provides flexible accessory storage while the bobbin case provides organized bobbin storage, resolving the contradiction between storage order and space flexibility.
Solution Approach 2:
The invention introduces a separate bobbin case as an intermediary component between the tidy and the bobbins. The bobbin case with its holding members provides a dedicated storage solution for bobbins, while the tidy remains available for other accessories. This intermediary structure resolves the conflict by creating a specialized sub-system for bobbin storage.
2Stability of the object's composition
If a bobbin tidy structure with U-shaped bobbin catching strips is used to line up bobbins on the inner bottom surface, then bobbins can be stored in order, but most of the inner space of the tidy is occupied and accessories cannot be stored
Solution Approach 1:
The invention separates the storage functions by creating a dedicated bobbin case that attaches to the tidy. The U-shaped holding members are confined to the bobbin case rather than occupying the entire tidy interior. This segmentation allows the tidy to maintain its full volume for accessory storage while the bobbin case provides organized bobbin storage.
Solution Approach 2:
The invention transitions from a two-dimensional layout (lining up bobbins on the bottom surface of the tidy) to a three-dimensional structure (a separate bobbin case with vertical walls and U-shaped holding members). This dimensional change allows bobbins to be stored in an organized manner without occupying the horizontal storage space needed for accessories in the tidy.
3Adaptability or versatility
If thread winding clips are not fixed to store bobbins, then storage space is flexible, but the clips may scatter in the tidy and bobbins cannot be stored in order
Solution Approach 1:
The invention segments the storage system into a tidy and a separate bobbin case. The holding members are attached to the bobbin case structure, providing stability and order for bobbin storage. The bobbin case itself can be detached from the tidy, maintaining flexibility. This segmentation resolves the contradiction by providing structure where needed (bobbin holding) and flexibility where appropriate (overall storage configuration).
Solution Approach 2:
The bobbin case serves as an intermediary structure that provides the necessary stability for ordered bobbin storage through its holding members, while remaining detachable from the tidy to preserve overall storage flexibility. This intermediary component mediates between the conflicting requirements of stability and flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for efficient, organized storage of bobbins and other sewing machine accessories, preventing clips from scattering and optimizing storage space by enabling flexible arrangement and connection of bobbin holding clips in various configurations within the storage case.

AI summary
A bobbin holding member holds a bobbin, and the bobbin holding member includes a body portion that holds detachably an outer periphery of a brim portion provided to both ends of a middle body section of the bobbin, wherein the body portion includes a fitting portion and a fitting target portion to be fitted to the fitting portion of any of the other bobbin holding members.
