Motorized Screen Control Interface for Adjustable Slats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control interfaces for motorized shading or solar protection elements, such as roller shutters and Venetian blinds, lack intuitive and simple control methods, often leading to inadvertent actuation of translation or orientation controls.
Innovation Solution
A control interface using a pointing tool with a main button, a secondary button, and a scrolling aid element, which activates software elements on a computer to detect mechanical actions and interpret them into deployment or orientation commands, establishing a functional link between the buttons and the electromechanical actuator for precise control of motorized adjustable blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate wheel interface is used for orientation control and separate buttons for translation control, then inadvertent actuation is prevented, but the control interface complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines translation control and orientation control into a single unified control interface. The wheel serves dual purposes: when the screen is fully deployed, it controls translation (opening/closing); when the screen is partially deployed, it controls orientation (blade angle). This merging eliminates the need for separate controls while preventing inadvertent actuation through context-aware functionality switching.
Solution Approach 2:
The control interface dynamically changes its function based on the screen's deployment state. The system detects whether the screen is fully deployed or partially deployed and automatically switches the wheel's control mode accordingly. This dynamic adaptation allows one control element to serve multiple functions without causing confusion or inadvertent actuation.
2Measurement precision
If multiple separate control interfaces are provided for different functions, then control precision is improved, but device complexity increases
Solution Approach 1:
The wheel is designed as a universal control element that can perform both translation control and orientation control. Depending on the screen's deployment state, the same physical interface adapts to control different parameters with equal precision. This multi-functionality reduces device complexity while maintaining control precision through context-aware operation.
3Ease of operation
If a graphical control interface on computer screen is used, then ease of operation is improved, but the risk of inadvertent actuation increases
Solution Approach 1:
The system incorporates feedback mechanisms that monitor the screen's actual deployment state and provide information to the control interface. The graphical interface reflects the current state and adjusts available controls accordingly, preventing users from issuing commands that would cause inadvertent actuation. The feedback loop ensures that control options are context-appropriate and reduces the risk of erroneous input.
