Window Vent Latch Sheath for Adjustable Sash Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vent latches are not versatile and cannot be easily moved or repositioned once installed, leading to ineffective sash resistance and potential window damage if not properly realigned, especially in applications requiring different latch types or locations.
Innovation Solution
A vent latch sheath with a spring and housing that allows for easy installation and adjustment along a window jamb, featuring a slot for the vent latch, a lip for engagement, and apertures for securing fasteners, enabling secure anchoring and alignment of vent stop latches, even in tiltable sashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vent latches are installed securely in window jamb, then reliability of sash control is improved, but ease of repositioning deteriorates
Solution Approach 1:
The vent latch system is divided into two separate components: a reusable sheath that remains installed in the window jamb, and a removable latch mechanism that can be easily transferred. This segmentation allows the sheath to provide stable, reliable mounting while the latch portion can be repositioned or replaced without removing the entire assembly, thus resolving the contradiction between secure installation and ease of repositioning.
Solution Approach 2:
The sheath acts as an intermediary component between the window jamb and the vent latch. It provides a standardized interface that simplifies installation and repositioning - the sheath remains permanently secured in the jamb while the latch mechanism can be easily attached and detached. This intermediary structure enables both reliable control and easy reconfiguration.
2Stability of the object's composition
If vent latches are firmly secured to window jamb, then stability of latch position is improved, but adaptability to different locations deteriorates
Solution Approach 1:
By separating the mounting function (sheath) from the latching function (latch mechanism), the system enables stable positioning through the permanently installed sheath while allowing easy adaptation by simply moving the latch mechanism to different sheaths or repositioning within the same jamb location.
Solution Approach 2:
The sheath is designed as a universal mounting component that can be installed in various locations within the window jamb. Once installed, it provides a standardized interface that can accommodate different latch mechanisms, making the system adaptable to different configurations and locations without requiring custom installation for each position.
3Ease of manufacture
If vent latches are installed without alignment tools, then ease of installation is improved, but manufacturing precision of alignment deteriorates
Solution Approach 1:
The sheath is pre-installed in the window jamb at the desired location before the latch mechanism is attached. This preliminary action establishes the correct position and alignment, so that when the latch is subsequently attached, proper alignment is automatically achieved without requiring complex alignment tools or procedures during the final installation step.
Solution Approach 2:
The sheath serves as an intermediary alignment reference that simplifies the installation process. By providing a fixed, pre-positioned mounting structure with standardized features, it guides the latch mechanism into correct alignment during attachment, eliminating the need for complex alignment tools while ensuring precise positioning.
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 solution provides a stable and adjustable vent latch system that ensures proper alignment and resistance, preventing undesired sash movement while allowing for easy repositioning and enhanced security through offset placement, thus addressing the limitations of traditional vent latches.
Implementation Method 1
The sheath includes a spring attached to the housing that engages the window jamb when the sheath is inserted into the window jamb
