Innovation Solution

A control mechanism that includes a solar power module, a storage device for heat exchange, a fan for distributing conditioned air, and an energy controller that uses an optical sensor to detect sunlight luminance and temperature to optimize the operation state of the air conditioner outdoor unit, reducing unnecessary energy usage by switching states based on threshold temperatures and sunlight availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the air conditioner outdoor unit switches frequently between active and inactive states to maintain temperature, then the temperature control responsiveness is improved, but the energy consumption increases

Engineering Contradiction:
Improveindoor space temperature controlVSAvoidenergy consumption of outdoor unit
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The solar power module performs preliminary action by generating electrical energy from sunlight before the air conditioner needs to operate. The optical sensor detects sunlight conditions in advance, and the energy controller pre-charges the storage device with solar energy, allowing the air conditioner to run during peak sunlight hours without switching frequently, thereby reducing energy consumption while maintaining temperature control.

Inventive Principle:
Principle #10Preliminary action

2Use of energy by moving object

If the air conditioner outdoor unit remains in active state continuously to avoid frequent switching, then the energy consumption is reduced, but the temperature control flexibility decreases

Engineering Contradiction:
Improveenergy consumption of outdoor unitVSAvoidoperation state adaptability
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The optical sensor continuously provides feedback on sunlight luminance and temperature to the energy controller. Based on this feedback, the energy controller dynamically adjusts the operation state of the outdoor unit - keeping it active when solar energy is abundant and switching it off when solar energy is insufficient, thus maintaining both energy efficiency and operational adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transitions from a static on/off control mode to a dynamic control mode where the outdoor unit's operation state changes continuously based on real-time solar energy availability detected by the optical sensor. This dynamic adjustment allows the system to optimize between continuous operation and frequent switching based on environmental conditions.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the system uses conventional power supply without solar integration, then the system simplicity is maintained, but the energy efficiency and operational costs increase

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The solar power module integrates multiple functions into a single component: it generates electrical energy for the air conditioner, provides temperature sensing through the optical sensor, and enables intelligent control through the energy controller. This multi-functional integration achieves energy efficiency improvements without proportionally increasing system complexity.
