Auxiliary Template for Cutting V-Sections in Window Profile Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting V-shaped sections in profile seals for windows and doors at corners is challenging due to the need for precise alignment and cutting techniques to ensure clean cuts and accurate bending at 90 degrees.
Innovation Solution
An auxiliary template with a molded body featuring parallel front and rear walls, 90-degree cutting guides, and a receptacle for the seal, allowing for guided cutting with a knife that rests on a cutting surface, ensuring clean cuts and accurate V-section creation, along with features like inclined ramps and vertical cutting guides for precise length adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual cutting of V-shaped sections in profile seals is performed without guidance, then the cutting process is simple and quick, but the cutting precision and alignment accuracy deteriorate
Solution Approach 1:
The patent introduces a molded body as an intermediary device that includes a receptacle for holding the profile seal and cutting guides for directing the knife. This intermediary structure provides the necessary guidance and alignment without requiring complex automated equipment, thus improving cutting precision while maintaining relative simplicity.
Solution Approach 2:
The cutting guides are integrated directly into the molded body, allowing the device to guide its own cutting process. The guides extend from the front wall to the rear wall and automatically align the knife at the correct 45-degree angle and position, enabling the system to self-regulate the cutting operation without external intervention.
2Manufacturing precision
If the seal is held firmly for precise cutting, then cutting accuracy improves, but the seal may be deformed or damaged
Solution Approach 1:
The receptacle in the molded body is designed with appropriate dimensions and flexibility to hold the profile seal securely during cutting. The receptacle accommodates the seal's cross-section without exerting excessive clamping force that could deform the seal, while still providing sufficient restraint to maintain cutting accuracy.
3Manufacturing precision
If the cutting guides extend fully through the molded body, then cutting precision is maximized, but the device complexity and material usage increase
Solution Approach 1:
The cutting guides are segmented into two parts: guides extending from the front wall to the rear wall for the primary cutting path, and additional guides extending from the front wall to the intersection point above the groove for the V-shaped section cutting. This segmentation allows each guide to perform its specific function without requiring the entire structure to be overly complex.

AI summary
To achieve maximum sealing effectiveness, window and door seals must be notched at the corners of the windows or doors to create a continuous sealing profile. Currently, this is achieved either using stationary machines or specialized miter shears. The auxiliary template is intended to replace existing tools, particularly when working on a small number of windows, or to enhance existing solutions through improved handling due to its smaller dimensions. The invention is an auxiliary template with a holder for a seal and cutting guides. The cutting guides are positioned to allow for the creation of a V-shaped notch in the sealing profile or for the sealing to be cut to length.
