Fenestration Handle With Gesture Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building fenestration control solutions, such as roller blinds and shutters, can be user-unfriendly, leading to operational mistakes and the loss or misplacement of remote controls, which complicates the intuitive control of sunlight and privacy settings.
Innovation Solution
A fenestration system with a handle integrated user interaction sensor arrangement that detects hand gestures around a specific rotation axis, allowing intuitive control of an electric architectural cover driver to adjust the covering of an insulating glass unit, reducing the need for remote controls and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handheld remote control is used to operate the covering unit, then user friendliness is improved, but the risk of losing the remote control and operational mistakes increases
Solution Approach 1:
The patent combines the control functionality with the existing handle structure of the fenestration. The sensor arrangement is integrated into the handle, merging the control device with the operational component, eliminating the need for a separate remote control that can be lost or misplaced.
Solution Approach 2:
The handle with integrated sensor arrangement serves itself by detecting hand gestures directly at the control location. The system uses the user's natural hand movements when interacting with the handle to control the covering unit, eliminating the need for external remote controls.
2Device complexity
If mechanical string or direct manual operation is used to control the covering part, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent replaces mechanical control mechanisms (strings, direct manual pulling) with a sensor-based detection system. The sensor arrangement detects hand gestures and rotational movements to control the electric motor, substituting mechanical operation with electronic sensing while maintaining operational simplicity.
Solution Approach 2:
The handle serves multiple functions: it acts as both the mechanical operator for the fenestration and the control interface for the covering unit. This multi-functionality eliminates the need for separate control mechanisms while maintaining device simplicity.
3Adaptability or versatility
If the rotation axis is not aligned with the bottom profile direction, then adaptability to different installation orientations is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a dynamic range for the rotation axis orientation (within 30 degrees of parallel to the bottom profile) rather than requiring exact alignment. This allows the system to adapt to different installation orientations while maintaining functional performance, balancing manufacturing tolerances with installation flexibility.
