Solution Overview

Problem

Conventional temperature control systems consume excessive energy to quickly reach a target temperature, neglecting user requirements and increasing power costs, as they do not efficiently manage operation power based on specific user-defined time constraints.

Innovation Solution

A temperature control system and method that utilize a control apparatus to calculate and execute an operation strategy, switching between multiple operation modes to minimize energy consumption, considering target time, target temperature, current temperature, and environmental factors, allowing for efficient temperature adjustment within a user-defined time frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the temperature control system performs cooling operation with higher operation power, then the temperature of indoor space can be reduced faster to achieve target temperature, but energy consumption increases

Engineering Contradiction:
Improvetemperature adjustment speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between different operation modes (first operation mode with higher cooling capacity and second operation mode with lower cooling capacity) based on real-time temperature feedback and time constraints. This dynamic adjustment allows the system to achieve fast temperature reduction when needed while minimizing energy consumption during maintenance phases, resolving the contradiction between speed and energy use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control apparatus implements periodic switching between operation modes rather than maintaining a single mode. The system alternates between high-power cooling operations to reduce temperature and lower-power operations to maintain temperature, creating a periodic action pattern that balances speed requirements with energy conservation.

Inventive Principle:
Principle #19Periodic action

2Loss of time

If the temperature control system uses higher operation power to reach target temperature early, then the temperature adjustment time is reduced, but the cost of using power increases

Engineering Contradiction:
Improvetemperature adjustment timeVSAvoidpower cost
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts operation power based on the relationship between remaining time and temperature difference. When time is充裕 and temperature is close to target, it switches to lower power mode to reduce costs. When time is constrained or temperature difference is large, it uses higher power to meet the time requirement, thus dynamically optimizing the balance between time loss and power cost.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control apparatus changes operational parameters (operation mode, power level) based on real-time conditions including time remaining and temperature differential. This parameter adjustment strategy allows the system to minimize power cost while ensuring the target temperature is reached within the required time frame.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the temperature control system maintains continuous high-power cooling operation, then the target temperature can be achieved and maintained reliably, but energy consumption increases

Engineering Contradiction:
Improvetemperature control reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses temperature sensors to continuously monitor indoor temperature and feeds this information back to the control apparatus. Based on the feedback and predefined control rules considering time constraints, the system intelligently switches between operation modes, ensuring reliable temperature control while minimizing energy consumption through optimized power management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control apparatus autonomously determines the appropriate operation mode based on real-time temperature data and time constraints without requiring continuous manual intervention. The system self-adjusts its power consumption levels to maintain reliable temperature control, optimizing energy usage based on its own operational state and environmental conditions.

Inventive Principle:
Principle #25Self-service

AI summary

A temperature control method used for changing a current temperature of an indoor space (Z1) to a target temperature (2422) in a target time (2420) comprises following steps: retrieving the target time (2420), the target temperature (2422) and an operation data of an indoor apparatus (20); retrieving an environmental factor; retrieving the current temperature (2422) of the indoor space (Z1) via a temperature sensor (22); calculating an operation strategy according to the target time (2420), the target temperature (2422), the operation data, the environmental factor and the current temperature; executing the operation strategy to control the indoor apparatus (20) to switch between multiple operation modes. This application uses a better energy-saving way to adjust the temperature of the indoor space (Z1) to achieve the target temperature (2422) in the target time (2420).
