Thermostat Rocker Switch Interface for Simpler Multi-Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermostats often confuse users with complex combinations of hard and soft buttons, leading to difficulty in adjusting settings due to overcrowded display screens with small icons, making it hard to find the right icon for specific functions.
Innovation Solution
A thermostat design featuring a rocker switch with a bar that can be rocked between two positions to adjust alpha-numeric icons on the display screen, allowing for easy increment or decrement of settings, such as temperature or time, while also selecting modes of operation like programming or user settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple hard buttons and touch sensitive areas are provided on the thermostat, then more functions can be controlled, but the device complexity and ease of operation deteriorate due to confusing interactions and sequencing requirements
Solution Approach 1:
The single rocker switch is designed to perform multiple functions across different operating modes. By pressing the switch in different sequences or holding it for different durations, the user can navigate menus, adjust temperature, select days, and modify time settings. This multi-functional design eliminates the need for multiple dedicated buttons while maintaining full thermostat functionality.
Solution Approach 2:
The rocker switch incorporates dynamic operation modes including brief presses for simple selections and extended holds for alternative functions. The system dynamically responds to the duration and pattern of user input, allowing the same physical control element to adapt its function based on contextual usage patterns, thereby simplifying the interface while preserving versatility.
2Quantity of substance
If multiple icons are displayed on the LCD screen to represent maximum functions, then more information is provided, but the icon size becomes small and difficult to locate
Solution Approach 1:
The thermostat interface divides the full set of functions into multiple screens or pages, with each screen displaying a manageable subset of icons. The single rocker switch enables users to navigate between these segmented displays, allowing each individual icon to remain large and easily identifiable while still providing access to the complete range of thermostat functions across multiple views.
3Measurement precision
If detailed instruction guides and user manuals are required to operate the thermostat, then precise control is achieved, but the ease of operation deteriorates due to the complexity of understanding button combinations
Solution Approach 1:
The thermostat interface provides on-screen prompts and visual feedback that guide users through the programming process without requiring external manuals. The display shows the current function being adjusted and the expected outcome, allowing users to operate the device intuitively by observing the screen responses rather than consulting detailed instruction guides.

AI summary
The invention provides for a controller such as a thermostat for an air handler including a housing having a circuit board and a display screen, the display screen having at least one alpha-numeric icon and a group of touch sensitive areas having at least two displayable touch sensitive areas. A microprocessor provided for the display screen. A sole mechanical button or switch is mounted in the housing and the button has a first end and second end and a touch surface extending between the first end and second end. The sole mechanical button signals the microprocessor in order to adjust the alpha-numeric icon, so that the combination of inputs received by the microprocessor from the group of touch pad sensitive areas and sole mechanical button provide for each and every adjustment required for all of the operational functions of the controller. The mechanical button may be a rocker switch.
