Motorized Window Treatment Control States for Daylight Overrides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load control systems for managing electrical loads in user environments, such as residences or office buildings, lack user-friendly interfaces for accessing and configuring settings for motorized window treatments, leading to inefficient energy management and user dissatisfaction.
Innovation Solution
A load control system that includes motorized window treatments with multiple control states (automated, bright override, manual, hold visor, and dark override) and a user interface for displaying control information, allowing users to visualize and adjust control parameters, including automated and override settings, to optimize daylight management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If automated control of motorized window treatments is implemented, then energy efficiency is improved, but user control and flexibility deteriorate
Solution Approach 1:
The system dynamically switches between automated control mode and manual override mode, allowing the control mechanism to adapt its degree of automation based on user needs. The user interface enables transition from fully automated operation to manual control when users require flexibility, resolving the contradiction by making the system's automation level dynamic rather than fixed.
Solution Approach 2:
The system provides self-service through automated control that manages window treatments based on environmental sensors and pre-set parameters, reducing energy consumption without requiring constant user intervention. Users can configure override parameters once, and the system autonomously handles daily operations, balancing energy efficiency with user control.
2Adaptability or versatility
If multiple control states and override parameters are added, then user flexibility is improved, but system complexity increases
Solution Approach 1:
The control system is segmented into distinct control states (automated, manual override, bright override, dark override) with clearly defined parameters for each. This segmentation allows users to understand and manage each state independently through a structured user interface, reducing perceived complexity while maintaining flexibility.
Solution Approach 2:
Override parameters and control settings are pre-configured in the system, allowing users to establish their preferences in advance. Once configured, the system automatically applies these pre-set parameters without requiring users to manually adjust complex settings each time they want to override automated control, simplifying the user experience.
3Ease of operation
If user interface for accessing control information is provided, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The user interface presents a simplified digital representation or copy of the control system's state and parameters, rather than exposing the full complexity of the underlying control logic. Users interact with intuitive visual displays of window treatment positions, daylight levels, and control modes, which mirror the actual system state without requiring users to understand the complex automated control algorithms.
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.
