Motorized Window Treatment Control With Daylight Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of load control systems, particularly in residential or office settings, face difficulties in configuring and understanding the settings for motorized window treatments, leading to inaccurate or unintended adjustments in daylight control, due to lack of clear information and confusing presentation of system operation.
Innovation Solution
A load control system that includes motorized window treatments with control states such as automated, bright override, manual override, and dark override, along with logging and graphical display of control information, allowing users to view and adjust parameters like maximum daylight penetration, shade positions, and override thresholds, and providing recommended adjustments based on user input for optimal daylight management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If automated control of motorized window treatments is implemented, then energy conservation and comfort are improved, but user understanding and configuration ease deteriorate
Solution Approach 1:
The system provides feedback to users through a user interface that displays control information, operational status, and configuration options for motorized window treatments. This feedback mechanism allows users to understand and adjust system behavior while maintaining automated energy-saving operations.
Solution Approach 2:
A controller serves as an intermediary between the automated control system and the user. It manages the complex automated operations internally while presenting simplified interaction interfaces to users, bridging the gap between sophisticated automation and user-friendly operation.
2Adaptability or versatility
If multiple control states and override options are added, then system adaptability and control flexibility are improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distinct control states (automated, manual override, bright override, dark override) that can be independently managed. Each state handles specific scenarios, reducing the cognitive load on users while maintaining comprehensive control flexibility.
Solution Approach 2:
The system dynamically transitions between different control states based on environmental conditions and user interactions. This dynamic behavior allows the system to adapt to changing conditions without requiring users to understand the underlying complexity of state management.
3Loss of information
If detailed control information is provided to users, then user understanding and configuration accuracy are improved, but information presentation complexity increases
Solution Approach 1:
The user interface presents information with local quality by displaying different levels of detail in different contexts. Common operations show simplified information while advanced configuration options are available when needed, allowing users to access complete information without being overwhelmed by it during routine use.
Data Source
AI summary
Motorized window treatments may each adjust a position of a covering material to allow light into a space in a building. The control information for controlling the motorized window treatments may be stored and/or accessed to understand how the motorized window treatments are operating. The control information may indicate a control state and/or a position of the covering material when an identified daylight intensity is being received at the space. The control information may inform a user of the operation of the motorized window treatments and allow the user to adjust various control parameters by which the motorized window treatments may be controlled. Recommended adjustments may also be provided to the user based on a user-identified problem with the operation of the motorized window treatments. The recommended adjustments to the control parameters may be accepted by the user and may be stored for being accessed and/or edited.
