Problem
Modern HVAC controllers are complex and difficult for novice and non-technical users to program and operate due to their increased functionality, necessitating a more intuitive and user-friendly interface.
Innovation Solution
The development of HVAC controllers featuring a touch screen interface that provides flexible information display and input options, including a processor, memory block, and data port for uploading and downloading settings, along with intuitive menu navigation and help screens, to simplify programming and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HVAC controllers include increased functionality and complexity to provide more features, then the system capabilities and features are improved, but the ease of operation deteriorates making programming difficult and confusing for novice users
Solution Approach 1:
The display screen is segmented into multiple regions (first region, second region, third region) that can independently display different types of information. This segmentation allows the interface to present complex system capabilities across multiple organized sections while keeping each individual section simple and easy to understand, thus maintaining ease of operation despite increased functionality.
Solution Approach 2:
The patent utilizes a multi-dimensional display approach by dividing the screen into multiple spatial regions rather than using a single linear display. This dimensional organization allows users to access different types of information simultaneously in different areas of the screen, reducing the complexity of navigation while providing comprehensive system control capabilities.
2Loss of information
If HVAC controllers provide comprehensive information display to improve user understanding, then the information completeness is improved, but the device complexity increases making the interface more complicated
Solution Approach 1:
Comprehensive system information is segmented and distributed across multiple display regions. The first region displays primary operational information, the second region displays secondary information, and the third region displays additional details. This segmentation allows complete information delivery while maintaining a clean, organized interface that does not appear complex to users.
Solution Approach 2:
Different regions of the display are assigned different qualities and purposes - the first region for primary information, the second for secondary information, and the third for supplementary details. This local differentiation allows comprehensive information presentation while each region maintains simple, focused content that avoids contributing to overall interface complexity.
Data Source
AI summary
An HVAC controller is described that is configured to be more intuitive and user friendly to program and operate than convention HVAC controllers. In some instances, the HVAC controller may include a touch screen interface that provides greater flexibility in displaying information to the user and/or soliciting information from the user.
