Sewing Template Frame with Non-Slip Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for guiding a sewing machine foot during quilting and large workpiece sewing require users to balance pressure on templates, leading to potential slipping or uneven stitching due to inadequate pressure control, which can ruin designs.
Innovation Solution
A sewing template system with a frame base, extensions, and a guide that supports the guide above the workpiece, allowing the sewing machine foot to move smoothly across the template surfaces without requiring constant pressure adjustment, using non-slip pads and rail retainers for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a user pushes hard on the template to prevent slipping, then the template stability is improved, but the sewing machine cannot move forward
Solution Approach 1:
The template system is segmented into multiple components: the template itself, support feet with non-slip pads at each corner, and a separate sewing machine. This segmentation allows the template to be stabilized independently through the support feet while the sewing machine moves freely on the quilt surface without being constrained by the template's position control mechanism.
Solution Approach 2:
Support feet with non-slip pads act as intermediaries between the template and the quilt surface. These feet provide the necessary friction to prevent template slipping while allowing the sewing machine to move independently. The non-slip pads transfer only the minimal necessary stabilizing force, decoupling the template's position control from the sewing machine's movement.
2Ease of operation
If a user does not push hard enough on the template, then the sewing machine can move easily, but the template slips and ruins the design
Solution Approach 1:
By segmenting the template into a stable base structure with separate support feet equipped with non-slip pads, the system provides sufficient friction to prevent slipping without requiring user pressure. The sewing machine operator can move the machine freely while the template maintains its position independently through the passive friction provided by the non-slip pads.
Solution Approach 2:
The non-slip pads on the support feet provide self-service stabilization by automatically generating the necessary friction force to prevent template slipping. This eliminates the need for the user to manually apply pressure to control template position, allowing the template to self-stabilize while the sewing machine moves freely.
3Device complexity
If templates are placed directly on the quilt surface, then the setup is simple, but the templates slip and require constant pressure adjustment
Solution Approach 1:
The template system is divided into the template body and separate support feet with non-slip pads. This segmentation adds minimal complexity to the setup while fundamentally solving the slipping problem. The support feet are attached to the template corners and provide passive stabilization through friction, eliminating the need for constant pressure adjustment by the user.
Solution Approach 2:
Support feet with non-slip pads serve as intermediaries between the template and the quilt surface. These feet provide the necessary friction interface to prevent slipping without requiring user intervention. The non-slip pads automatically adjust to provide adequate friction, eliminating the need for manual pressure control while maintaining simple setup procedures.
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
Enables precise and consistent stitching by maintaining template stability and reducing user effort, allowing for easier movement of the sewing machine foot across the workpiece without slipping, thus improving design accuracy and user experience.
Implementation Method 1
The templates often have a non slip surface to reduce the chance for the rulers to move
Implementation Method 2
A first rail retainer may be coupled to the first distal end and configured to rest on the second support rail, and a second rail retainer may be coupled to the second distal end and configured to rest on the second support rail

AI summary
A sewing template system and/or device may include a frame base configured to rest on a workpiece support frame. A first and second extension may each be coupled to a frame base. The first extension and second extension may be separated from each other and parallel to each other. A rail retainer may be coupled to each extension and configured to rest on the workpiece support frame. A frame top may be coupled to the extensions. A frame aperture may be formed by the frame base, first extension, second extension, and frame top. A guide may extend across the frame aperture between the first extension and the second extension, and the guide may be supported above the workpiece by the first extension and the second extension. A template, having guide surface(s) that is configured to guide the movement of a sewing machine foot, may be removably coupled to the guide.
