Motorized Window Treatment Control for Daylight Setting Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of load control systems, such as building managers or occupants, face difficulties in configuring and understanding the settings for motorized window treatments, leading to inaccurate or inefficient energy management 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 (automated, bright override, manual, hold visor, and dark override) and logs control information for display, allowing users to view and adjust parameters like daylight intensity, shade position, and control settings graphically, with recommended adjustments based on user input to optimize energy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If automated control of motorized window treatments is implemented, then energy conservation and occupant comfort are improved, but system complexity and difficulty of configuration increase
Solution Approach 1:
The system performs self-configuration by automatically detecting building geometry, window locations, and solar paths to generate optimized control parameters without requiring manual user input, thereby reducing system complexity while maintaining energy conservation benefits
Solution Approach 2:
The system pre-calculates and stores optimized control schedules and parameters based on building characteristics before operation begins, eliminating the need for complex real-time decision-making and simplifying ongoing system operation
2Manufacturing precision
If detailed control parameters and settings are provided to users, then configuration precision is improved, but information overload and user confusion increase
Solution Approach 1:
The configuration process is divided into discrete, manageable steps with only relevant parameters presented at each stage, allowing users to configure the system accurately without being overwhelmed by all parameters simultaneously
Solution Approach 2:
The system acts as an intermediary by automatically processing complex geometric and solar analysis calculations, presenting only simplified results and essential user decisions rather than raw computational details
3Adaptability or versatility
If manual override capability is added to automated control, then system adaptability is improved, but control complexity and user burden increase
Solution Approach 1:
The system continuously monitors occupancy, environmental conditions, and user interactions to automatically adjust control strategies, reducing the need for manual overrides while maintaining adaptability to changing conditions

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.
