Intelligent Window Pull Handle with Integrated Sensor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window pull handles lack a simple and unobtrusive means to control window functions such as locking and unlocking, requiring additional effort and compromising visual appearance when rotary handles are used.
Innovation Solution
Integration of a manually operable operating element and/or sensor on the pull handle with a signal transmitter to output electrical or electromagnetic signals upon actuation or gripping, enabling control of window functions like locking, tilting, and shut-off, and allowing for automatic triggering of functions when the handle is grasped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary handle is added to control locking functions, then window locking control is improved, but device complexity and visual appearance deteriorate
Solution Approach 1:
The pull handle is designed to perform multiple functions: it serves as both the primary gripping element for opening/closing the sash and as a control interface for locking functions through integrated operating elements (buttons, switches) or sensors that trigger locking mechanisms when actuated during handle manipulation
Solution Approach 2:
The locking control elements are merged into the pull handle structure itself, combining the gripping function and locking control function into a single integrated handle assembly, thereby eliminating the need for a separate rotary handle and reducing overall device complexity
2Adaptability or versatility
If a separate rotary handle is used for locking control, then locking function control is improved, but ease of operation deteriorates
Solution Approach 1:
The pull handle serves dual purposes as both the sash operation interface and the locking control interface, allowing users to perform both functions with a single handle manipulation action, thereby improving ease of operation by eliminating the need to switch between different handles
3Adaptability or versatility
If additional control elements are added to the pull handle, then window function control versatility is improved, but device complexity increases
Solution Approach 1:
The pull handle is designed as a multi-functional component that integrates gripping elements, operating elements (such as buttons or switches for locking), and sensors into a single structure, enabling control of multiple window functions including opening/closing, locking, tilting, and shut-off without requiring separate control mechanisms
Solution Approach 2:
The control elements and sensors are nested within or integrated into the pull handle structure itself, with the handle serving as a container for multiple functional components, thereby achieving high versatility while minimizing the overall space occupied and maintaining a relatively simple external appearance

AI summary
A window hardware assembly comprises a pull handle with a gripping section designed for human grasping. The pull handle is equipped with at least one manually operable control element and/or a sensor designed to detect an impending or actual grasping of the gripping section. The hardware assembly includes a signal transmitter connected to the at least one control element and/or the sensor, configured to output an electrical or electromagnetic control element signal and/or sensor signal when the at least one control element is manually operated and/or when the gripping section is detected by the sensor.
