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

VSEngineering 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

Engineering Contradiction:
Improvewindow locking controlVSAvoidhandle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If a separate rotary handle is used for locking control, then locking function control is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvelocking function controlVSAvoidoperating effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If additional control elements are added to the pull handle, then window function control versatility is improved, but device complexity increases

Engineering Contradiction:
Improvewindow function controlVSAvoidhandle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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.
