Yo-Yo Quilt Holding Tool With Guided Stitching Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of creating yo-yo quilts is labor-intensive and requires skill, as making a large number of uniform yo-yos with gathers can be burdensome and challenging, especially for those without experience.
Innovation Solution
A handicraft assisting tool comprising a supporting member with elongated holes and a holding member with recesses, which allows for easy placement and fixation of cloth, preventing movement and facilitating uniform stitching and cutting, thereby simplifying the creation of yo-yos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If yo-yos are made manually by folding, sewing, and knotting thread, then the quilt parts can be created with traditional craftsmanship, but the process becomes labor-intensive and requires significant skill to produce uniform results
Solution Approach 1:
The tool is divided into two separable components: a supporting member with elongated holes and a holding member with recesses. This segmentation allows the tool to be disassembled for easy cleaning and storage, while also enabling the holding member to be removed after stitching is complete, facilitating quick production of multiple yo-yos.
Solution Approach 2:
The tool introduces an intermediary device between the artisan's hands and the cloth, providing structured guidance for needle insertion and thread tensioning. The elongated holes and recesses act as intermediaries that standardize the stitching process, reducing skill requirements while maintaining production efficiency.
2Quantity of substance
If multiple yo-yos are produced to meet design requirements, then the quilt can achieve the desired decorative effect, but the labor burden on artisans increases significantly
Solution Approach 1:
The cloth is pre-positioned within the holding member before stitching begins. The holding member's recesses and the supporting member's elongated holes are pre-aligned to guide the needle and thread, eliminating the need for continuous manual positioning during the stitching process and reducing production time.
Solution Approach 2:
The tool structure itself performs the positioning and guiding functions that would otherwise require skilled manual operation. The elongated holes automatically guide needle insertion at correct angles and positions, while the recesses maintain proper thread tension, allowing less experienced artisans to produce consistent results more quickly.
3Manufacturing precision
If uniform size and gathers are required for all yo-yos, then the quilt achieves consistency in appearance, but this requires experienced artisans with specialized skills
Solution Approach 1:
The tool provides localized structural features at critical points: elongated holes at specific positions on the supporting member and corresponding recesses on the holding member. These localized features ensure uniform needle insertion angles and thread tensioning, guaranteeing consistent gathers and size across all yo-yos regardless of artisan skill level.
Solution Approach 2:
The tool physically constrains the stitching parameters (needle insertion angle, thread tension, stitch spacing) through its geometric structure. The elongated holes define specific angular orientations, while the recesses control thread tension, transforming variable manual operations into standardized parameters that ensure uniformity.
4Stability of the object's composition
If the holding member is securely fixed to the supporting member, then the cloth remains stable during stitching, but the tool becomes more complex with additional fixation mechanisms
Solution Approach 1:
The holding member and supporting member feature asymmetric recesses and elongated holes that align in a specific orientation. This asymmetric design provides inherent rotational stability, preventing the holding member from rotating on the supporting member without requiring additional symmetric fastening mechanisms.
Solution Approach 2:
The holding member nests onto the supporting member through the alignment of recesses with elongated holes. This nested arrangement provides stable fixation through geometric interlocking, where the holding member's recesses fit within the supporting member's hole structure, creating a stable connection without complex fasteners.

AI summary
A handicraft assisting tool (1) includes a plate-like holding member (3) and a supporting member (2) on which the holding member is placed. The supporting member (2) includes a main plate having a shape corresponding to the holding member (3) and a side plate (22) standing from the periphery of the main plate in the thickness direction of the main plate. The main plate is formed with a plurality of elongated holes (23) arranged adjacent to the periphery of the main plate and spaced from each other along the periphery. The holding member (3) includes a periphery formed with a plurality of recesses (33). Each of the elongated holes (23) includes opposite ends configured to communicate with the recesses (33) when the holding member (3) is placed on the supporting member (2).
