Reversible Slider Window Sash Width Limiter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for limiting the opening width of sashes or window doors require complex conversions and a large number of components to adapt to different requirements, making them inefficient in terms of ease of use and component management.
Innovation Solution
The device features a slider with a vertically aligned baffle surface that can be mounted with or without a locking mechanism, allowing for easy adaptation to various requirements without additional components, and includes a stopper design with holding means and a friction element for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different components are used for different requirements (locking vs non-locking), then the device can be adapted to different requirements, but the device complexity and quantity of components increase
Solution Approach 1:
The slider is designed with dual functionality: it can be mounted in two different orientations to provide either locking capability (when the locking means engage with the stopper) or non-locking capability (when mounted with the impact surface facing the stopper). This universal design eliminates the need for separate components for different requirements, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The mounting orientation of the slider is made dynamically adjustable rather than fixed. The slider can be intentionally mounted with either the impact surface or the locking means facing the stopper, allowing the system to adapt its behavior (locking or non-locking) based on installation requirements without changing the physical components
2Reliability
If the sash is held in the extended position by locking elements, then the opening width is limited securely, but the ease of operation is reduced when locking is not desired
Solution Approach 1:
The locking behavior is made dynamic through the mounting orientation of the slider. When non-locking operation is desired, the slider is mounted with the impact surface facing the stopper, allowing free opening and closing. When secure limitation is needed, the slider is mounted with the locking means facing the stopper, enabling engagement. This dynamic configuration resolves the contradiction between reliability and ease of operation
