HVAC Controller UI with Breadcrumb Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Special purpose controllers are often difficult to set up, program, and operate due to small displays and non-intuitive menu structures, leading to user frustration and underutilization of their features.
Innovation Solution
A special purpose controller with a user interface featuring a hierarchical menu structure, breadcrumb navigation, and instructional information displayed consistently, along with intuitive button arrangements, to facilitate easier navigation and understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a special purpose controller uses a small display and simple menu structure, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The user interface is segmented into distinct functional areas: a display region showing menu options and a separate instructional information region providing guidance. This segmentation allows the controller to present complex information in an organized, easy-to-navigate format without increasing physical device complexity.
Solution Approach 2:
Instructional information acts as an intermediary between the menu structure and the user. It mediates the interaction by providing context and guidance about what the user should do next, making the controller easier to operate without adding physical complexity.
2Adaptability or versatility
If a special purpose controller provides comprehensive programming options, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
Instructional information serves as a mediator that guides users through comprehensive programming options. It explains what each parameter does and how to configure it, making the setup process easier while maintaining full programming capability.
Solution Approach 2:
The controller provides self-service through on-screen instructional information that automatically guides users through the programming process. Users can independently configure complex parameters without external assistance, as the instructional information adapts to their current position in the setup process.
3Device complexity
If a special purpose controller uses a non-intuitive menu structure, then the device complexity is reduced, but the loss of information deteriorates
Solution Approach 1:
Instructional information acts as an intermediary that prevents users from becoming lost in the menu structure. It provides context about the current menu position and explains what information is being presented, maintaining user orientation without complicating the menu structure itself.
Solution Approach 2:
The instructional information provides continuous feedback to users about their position in the menu hierarchy and what actions are available. This feedback loop prevents users from losing their place or understanding what they are configuring.

AI summary
A temperature controller for controlling the temperature of an inside space that is serviced by one or more pieces of HVAC equipment. The temperature controller may include a controller having a control algorithm for controlling one or more pieces of HVAC equipment as well as a user interface that may be configured to display a hierarchical menu structure and to permit a user to traverse the menu structure. The user interface may be configured to display breadcrumbs that provide an indication to the user of the current location within a hierarchical menu structure, and in some cases, provide instructional information in a designated or common display area that helps instruct the user in using a particular menu or menu option. These and other features may help make the special purpose controller more intuitive to set up, program and operate.
