Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If programmable thermostats with multiple HVAC-system settings are provided, then energy-saving capability is improved, but device complexity increases making users intimidated and unable to use the features

Engineering Contradiction:
Improveenergy-saving capabilityVSAvoidnumber of controls
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The intelligent thermostat automatically learns and adapts to user temperature preferences and occupancy patterns without manual programming. The system performs self-configuration by monitoring user behavior and environmental data, eliminating the need for users to navigate complex settings while achieving energy-saving goals through automated optimization of HVAC operation schedules.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts temperature setpoints and HVAC operation parameters based on learned user preferences and real-time environmental conditions. By continuously adapting operational parameters rather than requiring fixed user programming, the thermostat achieves energy savings while maintaining simplicity in user interaction.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If intelligent thermostat performs high-power activities (wireless communications, display, calculations) continuously, then learning and adaptation capability is improved, but power consumption increases

Engineering Contradiction:
Improvelearning capabilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The intelligent thermostat implements periodic operation cycles where the high-power microprocessor performs learning calculations and wireless communications at scheduled intervals rather than continuously. Between these periodic high-power intervals, the system operates in low-power mode with basic thermostat functions, thereby maintaining adaptability while significantly reducing average power consumption from the power-stealing circuitry and battery.

Inventive Principle:
