Remote Air Conditioning Start System Positional Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote air conditioning start systems do not consider the user's positional information, leading to situations where the air conditioner is stopped too early, causing the vehicle's interior to return to an undesirable temperature before the user arrives.
Innovation Solution
A remote air conditioning start system that includes a portable terminal, a center server, and a vehicle, equipped with units to acquire user and vehicle positional information, allowing the controller to adjust the air conditioner's start timing and operation based on the distance between the user and the vehicle, and to restrict or delay the start if the distance is too large, thereby preventing unnecessary energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the air conditioner operation time is set based on a fixed duration without considering user position, then the system is simple to operate, but the air conditioner stops too early causing the vehicle interior to return to an undesirable temperature
Solution Approach 1:
The system performs preliminary calculation of the air conditioner operation time based on the user's current position and estimated arrival time at the vehicle. By anticipating when the user will arrive and pre-calculating the optimal operation duration, the system ensures the air conditioner stops at the right moment to maintain comfortable temperature without requiring complex real-time adjustments.
Solution Approach 2:
The system incorporates feedback by continuously monitoring the user's positional information and comparing it with the vehicle location. This feedback loop allows the system to dynamically adjust the air conditioner operation time based on the actual distance and estimated arrival time, ensuring the vehicle interior temperature remains comfortable throughout the user's approach.
2Temperature
If the air conditioner operates for a long duration to ensure comfortable temperature upon arrival, then the temperature comfort is maintained, but energy consumption increases
Solution Approach 1:
The system calculates the optimal air conditioner operation time in advance by determining the user's estimated arrival time based on current position and speed. This preliminary calculation allows the air conditioner to operate only for the necessary duration to achieve comfortable temperature, avoiding unnecessary extended operation and associated energy waste.
Solution Approach 2:
The system dynamically adjusts the air conditioner operation time based on real-time user position data and movement patterns. By continuously updating the estimated arrival time and recalculating the optimal operation duration, the system adapts to changing conditions to minimize energy consumption while ensuring temperature comfort is maintained until the user arrives.
3Loss of energy
If the system restricts air conditioner start when user distance is large, then energy wastage is prevented, but the system cannot ensure temperature comfort if user arrives later than expected
Solution Approach 1:
The system dynamically evaluates the user's position, movement speed, and estimated arrival time to make intelligent decisions about air conditioner operation. When the user is far away, the system calculates whether the estimated arrival time suggests a delayed approach; if so, it adjusts the operation duration accordingly rather than simply restricting start, thus preventing energy waste while maintaining reliability of temperature comfort.
Solution Approach 2:
The system uses continuous feedback from positional information to monitor whether the user is approaching faster or slower than initially estimated. This feedback allows the system to adjust the air conditioner operation timing in real-time, ensuring that even if the user arrives later than expected, the vehicle interior temperature remains comfortable while avoiding unnecessary energy consumption from premature or extended operation.
