Quilt Marking Assembly Using Yarn Grid and Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking devices for quilting lack precision and consistency in marking blankets, as they often rely on pre-printed grids or templates that may not accurately align with the blanket's dimensions, leading to inaccuracies in quilting patterns.
Innovation Solution
A marking device comprising a measuring tape with graduated indicia, pins for even spacing on a quilting frame, and a roll of yarn stretched between pins to create a customizable grid, with a marker to mark intersections for precise quilting, allowing for accurate and customizable marking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-printed grids or templates are used for marking blankets, then the marking process is simplified, but the precision and alignment accuracy with the blanket's dimensions deteriorates
Solution Approach 1:
The patent employs a flexible measuring tape that can be dynamically adjusted and repositioned along the blanket, allowing the grid system to adapt to the blanket's actual dimensions rather than being fixed to a rigid template. This dynamic approach enables precise alignment while maintaining ease of operation.
Solution Approach 2:
The patent allows for changing the parameters of the grid system by adjusting the measuring tape's position and orientation on the blanket. This enables the grid to be customized to match the blanket's specific dimensions, resolving the contradiction between using a simple template and achieving precise alignment.
2Device complexity
If a fixed template is used for quilting, then the device complexity is reduced, but the adaptability to different blanket dimensions deteriorates
Solution Approach 1:
The patent creates a universal marking system using a flexible measuring tape that can be applied to blankets of various sizes and dimensions. The tape can be repositioned and reconfigured to accommodate different blanket dimensions, providing multi-functionality without requiring multiple specialized templates.
Solution Approach 2:
The flexible nature of the measuring tape allows it to be dynamically adjusted to fit different blanket dimensions, making the simple device adaptable to various quilting projects while maintaining its structural simplicity.

AI summary
A quilt marking assembly includes a measuring tape which has graduated indicia printed thereon to measure distance along a blanket when the measuring tape is stretched along the blanket. A plurality of pins is provided and each of the pins is insertable into a quilting frame upon which the blanket is positioned to mark a preferred location on the blanket. The pins are positionable such that the pins are evenly spaced along a distance measured by the measuring tape. A roll of yarn is dividable into a plurality of lengths of the yarn. Each of the lengths of yarn is stretchable between a respective pair of pins to define a grid on the blanket. A marker is provided to mark the blanket at each of a plurality of intersections of the grid defined by the lengths of yarn for quilting the blanket.
