Programmable Thermostat Presets for Simpler Setback Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most programmable thermostats are not programmed due to the complexity and number of non-intuitive steps required, leading to low user adoption and energy inefficiency despite their widespread installation.
Innovation Solution
A programmable thermostat with a simplified and intuitive interface that allows users to program common settings with minimal commands, using preconfigured options for five-day work week and two-day weekend schedules, reducing the need for manual specification of event times and temperatures through a graphic display and onscreen text instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional programmable thermostat programming is implemented with multiple events per day and seven-day scheduling, then energy efficiency and programmability benefits are enhanced, but the number of commands and programming complexity increase significantly
Solution Approach 1:
The programming interface is segmented into simplified preset options (e.g., 'Away', 'Sleep', 'Five and Two') that break down the complex seven-day, four-events-per-day programming into manageable, pre-configured templates. Users select from these segments rather than programming each event individually, reducing the number of commands while maintaining energy efficiency benefits.
Solution Approach 2:
The thermostat includes pre-configured programming templates with default temperature setbacks and schedules already established. These preliminary actions (pre-set programs) allow users to implement energy-efficient scheduling without performing the complex programming steps, thereby reducing programming complexity while preserving energy savings.
2Adaptability or versatility
If comprehensive programming options with multiple events per day are provided, then adaptability and customization are improved, but the number of commands and time required for programming increase
Solution Approach 1:
The system provides pre-configured programming templates that represent common scheduling patterns (e.g., work week vs. weekend, away mode, sleep mode). These preliminary configurations allow users to adapt to their needs by selecting appropriate templates rather than programming from scratch, significantly reducing programming time while maintaining adaptability.
Solution Approach 2:
The thermostat implements a tiered programming approach where basic common settings are provided through simplified presets (partial action), while more comprehensive customization options remain available but are not required for most users. This allows the system to achieve sufficient adaptability for the majority of users without requiring them to invest excessive time in programming.
3Manufacturing precision
If detailed programming instructions and user manual references are provided, then programming accuracy and completeness are improved, but ease of operation deteriorates due to non-intuitive steps
Solution Approach 1:
The thermostat interface is designed to be self-explanatory and intuitive, with clearly labeled buttons and display messages that guide users through programming without requiring external user manuals. The system serves itself by providing embedded instructions and logical flow that make programming accurate and complete while maintaining ease of operation.
Solution Approach 2:
The programming interface is segmented into logical, intuitive steps with clear visual cues and confirmation displays. Each programming stage is broken down into manageable sections with explicit instructions displayed on the thermostat itself, eliminating the need to refer to external manuals and improving both accuracy and ease of operation simultaneously.

AI summary
A programmable thermostat usable to program their thermostat in a more intuitive manner using the fewer commands. The programmable thermostat provides a simplified level of programming that is intuitive and quick, based on a common set of settings, such as a nighttime setback programming that automatically adjusts the thermostat setpoint down in the evening and resetting the setpoint up in the morning, and a “five and two” programming reflecting the normal five-day work week and two-day weekend, as well as four events per day during the work week but only two events during the two weekend days. By compromising infinite flexibility and customization of programming for the efficiency of assuming that the most common settings are sufficient for most users, and these most common settings can be accomplished with a greatly reduced set of intuitive commands, making it easier for users to making use of thermostat programming.
