Solution Overview

Problem

Existing air conditioning systems in vehicles require several seconds to detect the temperature and select an appropriate mode, leading to user inconvenience due to waiting times before remote air conditioning is initiated.

Innovation Solution

The system immediately selects the second air conditioning mode using battery power to start air conditioning, followed by a switch to the first mode based on exterior temperature detection, reducing the need for pre-detection delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system detects temperature and selects air conditioning mode before initiation, then the appropriate mode can be chosen, but the user experiences waiting time before air conditioning starts

Engineering Contradiction:

Improvemode selection accuracyVSAvoidwaiting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs temperature detection and mode selection in advance before the user requests air conditioning, so that when the user does request it, the system can immediately start without waiting for detection and selection processes

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically detects temperature and selects appropriate mode without requiring user input or waiting for user confirmation, making the system self-activating based on pre-detection results

Inventive Principle:

Principle #25Self-service

2Temperature

If the system uses engine power for remote air conditioning, then heating capability is improved, but energy consumption increases

Engineering Contradiction:

Improveheating capabilityVSAvoidenergy consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The system changes the energy source parameter from engine power to battery power, altering the operating conditions to reduce energy consumption while maintaining heating capability through electric heater or heat pump operation

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system replaces the mechanical engine-driven air conditioning system with an electrically-driven system using battery power, eliminating the need to run the engine solely for air conditioning purposes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
