Solution Overview
Problem
Existing building aperture cover systems, such as windows, are often unintuitive and require substantial manual effort for opening and closing, leading to user operation mistakes and difficulties, especially for guests and in scenarios where remote controls are lost or unclear in functionality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a remote control system is used to operate the building aperture cover, then automation is improved, but reliability deteriorates due to loss or unclear functionality of remote controls
Solution Approach 1:
The patent introduces an intermediary sensor arrangement in the handle that detects physical user interactions and converts them into control signals. This mediator bridges the gap between manual operation and automated actuation, allowing the system to maintain reliability through direct physical interaction while achieving automation through sensor-based control signal generation.
2Reliability
If manual operation of the building aperture cover is required, then reliability is improved, but ease of operation deteriorates due to substantial manual effort required
Solution Approach 1:
The patent replaces the purely mechanical operation system with a hybrid system that incorporates sensor arrangements to detect user interactions. The sensor arrangement converts physical interactions into control signals that drive the actuator, substituting direct mechanical force application with a more efficient sensor-actuator mechanism while maintaining the reliability of direct user control.
3Ease of operation
If control elements and sensors are integrated in the handle, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the control elements and sensors directly into the handle structure, combining multiple functions (user interaction interface, sensor detection, and control signal generation) into a single integrated component. This merging approach improves ease of operation by providing intuitive control while managing device complexity through functional integration rather than separate components.
4Ease of operation
If directional user interactions are detected to control opening and closing, then ease of operation is improved, but measurement precision requirements increase
Solution Approach 1:
The patent applies local quality by positioning sensors at specific locations on the handle where they can detect directional user interactions. Different sensor locations and orientations provide specialized detection capabilities for specific interaction directions, allowing the system to distinguish between opening and closing commands with adequate precision while maintaining ease of operation through intuitive physical interactions.
