Window Lining Measuring Tool with Arcuate Track and Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for installing window linings face challenges in accurately measuring and cutting complex shapes, especially in inclined roof installations, where the geometry requires adaptation based on roof inclination and wall thickness, and there is a need for simplified and fail-safe measurement and installation processes.
Innovation Solution
A measuring tool comprising an angle element with an arcuate track and a ruler element, where the pin's position in the track defines the angle between the elements, allowing for correct marking of cutting lines on the lining panels, and featuring indicating means for easy alignment and marking of apertures for fastening holes, facilitating the preparation of window linings for various inclinations and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual measurement and cutting methods are used for window lining panels, then the installation process requires multiple measuring steps and manual adaptation, but this increases the risk of incorrect installation and reduces measurement precision
Solution Approach 1:
A measuring tool serves as an intermediary device between the window frame and the lining panels. The tool includes an angle element with an arcuate track and a ruler element with a pin that slides along the track, allowing the pin's position to define the angle between elements. This intermediary tool transfers the geometric relationships directly to the panels, enabling precise marking of cutting lines and aperture positions without complex calculations or multiple measurement steps.
2Ease of operation
If the measuring tool includes indicating means for alignment and marking, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The measuring tool incorporates indicating means that automatically align with pre-marked positions on the lining panels. The angle element has indicating means that match corresponding markings on the panel, and the ruler element has indicating means that mark aperture positions. When the tool is correctly positioned, the indicating means self-align and self-mark, eliminating the need for additional measuring steps or complex alignment procedures by the operator.

AI summary
The measuring tool (1) is intended for preparation of a window lining (7) to fit between a window frame (4) and an inner wall (5), and comprises an angle element (2) and a ruler element (3). The angle element (2) has a first edge (21) adapted for abutment with the window frame (4) and a second edge (22) substantially perpendicular to the first edge (21), and including an arcuate track (23). The ruler element (3) has two side edges (31, 32) and two opposite end edges (34), and a pin (33) near one end edge, the pin (33) being slidingly accommodated in the arcuate track (23). The angle element (2) and the ruler element (3) are adapted to be rotated through a predefined angle interval defined by the ends (23a, 23b) of the track (23) in the angle element (2) to position at least one side edge (32) of the ruler element (3) and the second edge (22) of the angle element (2) at an angle with respect to each other.
