Pivotal Marking Tool for Window Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing windows in building structures are time-consuming and prone to errors due to the trial-and-error nature of creating openings in inner walls, especially when angled cuts are required, which can affect the accuracy and safety of the installation process.
Innovation Solution
A marking tool with a window engaging member that uses elastic tongues for frictional engagement with the window frame, allowing for precise marking of cutting locations and stable attachment, enabling accurate and efficient installation by indicating the intended cutting location without requiring additional actions to relocate it, thus reducing the risk of erroneous installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a smaller initial opening is made in the inner wall at the intended centre of the window, then the risk of the opening being larger than the window dimensions is reduced, but the installation time increases and the procedure becomes susceptible to installation errors
Solution Approach 1:
The marking tool is attached to the window frame before the opening is cut, allowing the precise location and dimensions of the opening to be marked in advance on the inner wall. This preliminary marking action eliminates the need for trial-and-error expansion and ensures accurate opening size from the start, thereby reducing both time and errors.
2Illumination intensity
If a protractor with variable angle measurement is used for piercing at an angle different from perpendicular, then more natural light can enter through the opening, but the device complexity increases
Solution Approach 1:
The marking tool integrates multiple functions: it attaches to the window frame, provides angle indication through its structure, and marks the opening location. By combining these functions into a single tool, the patent eliminates the need for separate protractors and level tools, reducing device complexity while still enabling angled piercing for optimal natural light entry.
3Ease of operation
If the marking tool is removably attached to the frame, then both hands are free to perform other actions, but the attachment stability must be maintained
Solution Approach 1:
The marking tool is designed as a separate, removable component that attaches to the window frame during the marking process. This segmentation allows the tool to be easily attached and detached, providing hands-free operation during marking while maintaining stability through its attachment mechanism. The tool can be removed after marking without affecting the window frame or opening accuracy.
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
The marking tool facilitates accurate and efficient window installation by providing a stable and precise indication of cutting locations, reducing the risk of errors and allowing the installer to perform other actions with both hands free, thereby improving overall installation conditions.
Implementation Method 1
The at least one leg of the window engaging member is configured to be introduced in a groove in the window frame of the roof window, and the removable attachment is provided by frictional engagement between the at least one leg and the groove in the mounted condition of the marking tool.

AI summary
A marking tool (1) for preparation of an opening for a window in an inner wall of a building structure, comprising a window engaging member (3) having a first surface (31), and a marker holder member (5) having angle indicating means (51) in which the window engaging member (3) and the marker holder member (5) are pivotally connected through a pivotal connection. The first surface (31) of the window engaging member (3) is adapted for abutment with the window frame, wherein the marker holder member comprises a marker locking mechanism (53), where the marker locking mechanism (53) has a longitudinal axis (55). The pivotal connection allows modifying an angle (α) between a plane defined by the first surface and the longitudinal axis (55) of the marker locking mechanism (53). The angle indicating means (51) is configured to indicate the angle (α) of the axis of the marker locking mechanism (53) when the marking tool (1) is abutted against the window, and the marker locking mechanism (53) is provided with a marking device (7) for indicating an intended cutting location.
