Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC system controls require complex and inaccessible mechanisms for changing settings and troubleshooting, making it difficult for users and technicians to conveniently view and modify system information, especially in hard-to-reach locations.
Innovation Solution
A user interface module with a visual display and keypad for navigating menus and selecting control inputs, designed to be easily mounted and used within HVAC equipment cabinets, providing access to system information, error codes, and troubleshooting options, while being resistant to environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If jumpers and DIP switches are used for control system changes, then the control system can be configured, but the interface becomes inaccessible and difficult to use
Solution Approach 1:
A remote interface device is introduced as an intermediary between the user and the HVAC control system. This remote interface communicates with the control system via telephone lines or other communication channels, allowing users to access and modify control parameters without physically accessing the inaccessible control system location. The intermediary translates user-friendly inputs into control system commands.
Solution Approach 2:
The patent replaces mechanical jumpers and DIP switches with an electronic communication-based interface. Instead of physically manipulating mechanical components located in inaccessible areas, users interact with an electronic interface that transmits commands remotely through communication lines, substituting mechanical interaction with electronic signaling.
2Ease of operation
If control systems are located in inaccessible places, then the HVAC system can be compactly installed, but user access for viewing and modifying settings becomes difficult
Solution Approach 1:
The remote interface device serves as a mediator that bridges the gap between the user and the inaccessible control system. It handles all communication and data transmission remotely, eliminating the need for users to physically travel to or access the location of the control system to view or modify settings.
Solution Approach 2:
The user interface functions are extracted from the physical control system location and placed in a remotely accessible interface device. This separation allows the control system to remain in its optimal (inaccessible) location while the interface functions are available wherever the user can access the communication channel.
3Loss of information
If sophisticated electronic controls are used, then system monitoring and control capabilities are enhanced, but the user interface becomes more complex and difficult to use
Solution Approach 1:
The remote interface device acts as an intermediary that simplifies complex system information for users. It receives detailed data from the sophisticated control system and presents it in an easily understandable format, translating technical parameters into user-friendly displays and controls.
Solution Approach 2:
The interface creates simplified copies or representations of the complex control system data. Instead of presenting raw technical information directly from the control system, it generates user-friendly copies of the information that maintain essential details while removing complexity.

AI summary
A user interface for a control system for an air conditioning apparatus includes a visual display and keys for scrolling menu items and entering commands to the control system. The interface is mounted in the apparatus cabinet and on a rotatable bracket to orient the interface for ease of reading the display and actuating the respective keys.
