Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners lack the ability for users to customize the temperature curve during sleep mode, leading to discomfort for many individuals, as the existing sleep function is not adaptable to personal preferences and geographical environments.
Innovation Solution
An air conditioner system that allows users to set a user-defined temperature curve using a remote controller, enabling personalized temperature adjustments over time, with data stored in the air conditioner's MCU control chip and transmitted via infrared signals for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sleep mode temperature curve is implemented based on mass data statistics, then the air conditioner can provide automatic temperature adjustment during sleep, but it cannot adapt to individual user preferences and geographical environments
Solution Approach 1:
The system pre-provides multiple typical temperature curve patterns (e.g., gradual increase, step increase, gradual decrease, step decrease) that users can select in advance. This allows users to choose their preferred pattern before sleep begins, eliminating the need for complex real-time adjustments while still providing personalized temperature control.
Solution Approach 2:
The system dynamically switches between different temperature curve patterns based on user selection and automatically adjusts the temperature according to the selected pattern during sleep. This dynamic adaptation enables the system to respond to individual user preferences while maintaining operational simplicity through automated execution of the selected pattern.
2Ease of operation
If the sleep mode automatically adjusts temperature according to pre-set patterns, then the operation is simplified, but the user cannot customize the temperature curve according to personal habits
Solution Approach 1:
Users pre-select their preferred temperature curve pattern (gradual increase, step increase, gradual decrease, or step decrease) before entering sleep mode. The system then automatically executes the selected pattern without requiring further user intervention, combining ease of operation with customization capability.
Solution Approach 2:
Once the user selects a temperature curve pattern, the system autonomously executes the temperature adjustment according to the selected pattern throughout the sleep period. The air conditioner independently manages the temperature control process, eliminating the need for continuous user input while maintaining personalized temperature profiles.
3Device complexity
If the air conditioner functions only as a cold source or hot source in sleep mode, then the system operation is simplified, but it cannot provide comprehensive comfort according to human physiological changes
Solution Approach 1:
The system changes the temperature parameter dynamically during sleep mode based on the selected curve pattern, transitioning from static temperature control to dynamic temperature adjustment. This allows the air conditioner to adapt to human physiological changes during sleep while maintaining simplified system operation through automated pattern execution.
