Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioning systems face issues with asynchronous temperature display and scalability when converting between Celsius and Fahrenheit scales due to the linear but non-integer corresponding relationship, leading to errors and complexity in table lookup methods.
Innovation Solution
The system employs first and second converters using the Fahrenheit-Celsius standard conversion formula, rounding Fahrenheit data, and a comparison model to ensure synchronous display and scalability by converting Celsius data to Fahrenheit and vice versa, avoiding table lookup and maintaining accurate temperature representation.

Engineering Contradiction Analysis
1Speed
If table lookup method is used for temperature conversion, then conversion speed is improved, but accuracy deteriorates due to rounding errors and non-integer relationships
Solution Approach 1:
The patent replaces the mechanical table lookup method with a mathematical formula-based conversion system. The conversion formula F = C × 9/5 + 32 is implemented through computational logic that directly calculates temperature values without relying on pre-stored tables, thereby eliminating rounding errors inherent in table methods while maintaining high conversion speed through efficient arithmetic operations.
Solution Approach 2:
The patent changes the conversion approach from discrete parameter values (table entries) to continuous parameter calculation (formula-based). By using the exact conversion formula with floating-point arithmetic, the system maintains precision across the entire temperature range rather than being limited to discrete table values, thus resolving the accuracy-speed contradiction.
2Ease of manufacture
If table lookup method is used for temperature conversion, then implementation is simplified, but scalability deteriorates when adapting to different temperature scales
Solution Approach 1:
The patent implements a universal temperature conversion system based on mathematical formulas that can handle multiple temperature scales (Celsius, Fahrenheit, Kelvin, etc.) through a single unified approach. The conversion logic uses fundamental thermodynamic relationships that are scale-independent, allowing the same computational framework to adapt to any temperature scale without requiring separate table structures or conversion methods for each scale.
Solution Approach 2:
By replacing the mechanical table lookup system with formula-based computation, the patent achieves both implementation simplicity and scalability. The mathematical formulas provide a clear, concise implementation approach that is easier to code and maintain than large conversion tables, while simultaneously enabling seamless adaptation to different temperature scales through parameter adjustment rather than structural modification.
3Device complexity
If asynchronous temperature display is used in multi-terminal systems, then device complexity is reduced, but reliability deteriorates due to inconsistent temperature representation
Solution Approach 1:
The patent implements a feedback mechanism where the central controller continuously monitors temperature data from sensors and actively adjusts the displayed temperature values across all terminals. The controller receives real-time temperature readings, performs precise conversions using the conversion formula, and pushes updated values to all connected terminals, ensuring synchronous and consistent display. This active feedback loop eliminates the inconsistencies that would arise from asynchronous independent displays.
Solution Approach 2:
The patent merges the temperature conversion and distribution function into a centralized controller that serves all terminals. Instead of each terminal independently converting and displaying temperature (which would lead to asynchrony and inconsistency), the system combines these functions in a single central unit that generates authoritative temperature values and distributes them to all terminals, ensuring unity and reliability across the entire system while keeping individual terminal complexity low.
Data Source
AI summary
An air conditioning system includes an outdoor unit, an indoor unit, a wire controller, a terminal device, a first converter, and a second converter. The first converter is configured to obtain Celsius temperature data currently transmitted in the air conditioning system, convert the currently transmitted Celsius temperature data to first Fahrenheit temperature data by using a Fahrenheit-Celsius standard conversion formula, round the first Fahrenheit temperature data to obtain target Fahrenheit temperature data, and send the target Fahrenheit temperature data to at least one of the wire controller or the terminal device. The second converter is applied to the wire controller or the terminal device and is configured to convert received Fahrenheit temperature data to target Celsius temperature data. A method for controlling the air conditioning system is also described.
