Sewing Machine Module Frame and Cover Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for sewing machine modules are complex and difficult to produce modules with high rigidity, as they involve bending metal plates and attaching mechanisms from multiple directions, which complicates the formation of a rigid base plate.
Innovation Solution
A sewing machine module design that incorporates a frame, a cover member, and a joining mechanism, where the frame supports the feed and shuttle mechanisms with the cover member formed into a flat plate shape, providing high rigidity without the need for complex bending or multiple directional attachment of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the base plate is formed by bending a metal plate into a complex shape and members are attached from various directions, then high rigidity is ensured, but the manufacturing process becomes complicated
Solution Approach 1:
The base plate is divided into multiple separate members (first base member, second base member, third base member) that are joined together using joining members. This segmentation allows each member to be manufactured separately with simpler processes while achieving the required rigidity through their combined structure, resolving the contradiction between rigidity and manufacturing complexity
Solution Approach 2:
Multiple base members are stacked and joined together in a layered configuration, with joining members penetrating through multiple layers to secure them. This nesting approach creates a rigid composite structure from simpler individual components, eliminating the need for complex bending processes while maintaining structural integrity

AI summary
A sewing machine module mounted in a sewing machine that includes a feed mechanism, a shuttle mechanism, a frame that covers at least a portion of a side face of the feed mechanism, a portion of a side face of the shuttle mechanism, a portion of a bottom face of the feed mechanism, and a portion of a bottom face of the shuttle mechanism and that supports the feed mechanism and the shuttle mechanism in a state in which a top side of the feed mechanism and a top side of the shuttle mechanism are open, a cover member that is formed into a flat plate shape and that covers the top side of the feed mechanism and the top side of the shuttle mechanism that are supported by the frame, and a joining mechanism that joins the frame and the cover member.
