Solution Overview

Problem

Current technologies do not effectively allow for remote operation of vehicle windows or sunroofs to ventilate the interior based on temperature differences, which can lead to discomfort and security issues.

Innovation Solution

An information processing device and method that acquires temperature data inside and outside a vehicle, generating commands to open or close windows based on temperature differences, allowing remote operation to ventilate the vehicle while also considering security by preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If windows are opened for ventilation based on temperature differences, then comfort inside the vehicle is improved, but security against unauthorized entry deteriorates

Engineering Contradiction:

Improvetemperature difference between inside and outside vehicleVSAvoidunauthorized entry risk

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The system dynamically changes the window opening parameter based on temperature differential. When the temperature difference exceeds a predetermined threshold, the window opens automatically; when the threshold is not met, the window remains closed. This parameter-based control resolves the contradiction by opening windows only under specific thermal conditions that justify the ventilation need while limiting exposure time.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system continuously monitors temperature inside and outside the vehicle, processes this feedback information, and adjusts window opening decisions accordingly. The control unit receives temperature data, compares it against thresholds, and automatically adjusts window state. This closed-loop feedback mechanism ensures windows open only when thermal conditions warrant ventilation, balancing comfort improvement with security maintenance.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If windows are opened remotely without temperature verification, then ease of operation is improved, but energy loss increases

Engineering Contradiction:

Improveremote window operationVSAvoidair conditioning efficiency

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The system performs preliminary temperature verification before executing window opening operations. The control unit checks whether the temperature differential meets the predetermined threshold before allowing remote window opening. This preliminary action prevents unnecessary window openings that would waste energy, while still providing ease of operation when conditions are appropriate.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses temperature differential as a controlling parameter that must exceed a predetermined threshold to enable remote window opening. This parameter-based gatekeeping ensures that windows are opened remotely only when thermal conditions justify energy expenditure on ventilation, preventing premature or unnecessary openings that would compromise air conditioning efficiency.

Inventive Principle:
