Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional windows and doors lack automation, making it inconvenient to manage ventilation, energy efficiency, and security, as users often cannot manually open or close them when busy or away, and there is no real-time feedback on drafts or temperature effects.
Innovation Solution
An automated sliding window mechanism with motors, controllers, air pressure sensors, and temperature sensors that can open or close windows based on user preferences, real-time conditions, and pre-programmed settings, allowing for automatic operation and override via smart devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If windows are opened manually for ventilation, then air flow is achieved, but user convenience deteriorates when users are busy or away
Solution Approach 1:
The window system automatically monitors indoor and outdoor air pressure, detects drafts, and opens/closes windows without human intervention. The processor continuously reads sensor data and autonomously controls the motor to adjust window position, enabling the system to serve itself rather than requiring manual user operation.
Solution Approach 2:
The patent replaces manual mechanical window operation with an automated electromechanical system. A motor driven by the controller substitutes for human hand operation, while electronic sensors and processors replace human sensory detection and decision-making, transforming a purely mechanical system into an intelligent automated system.
2Reliability
If windows are closed for security, then security is improved, but ventilation capability deteriorates
Solution Approach 1:
The window system dynamically adjusts its state between closed and open positions based on real-time sensor readings. Rather than remaining statically closed for security, the system continuously monitors air pressure differentials and automatically opens when drafts are detected, creating a dynamic balance between security and ventilation needs.
Solution Approach 2:
The system uses air pressure sensors to provide continuous feedback about draft conditions. The processor receives real-time pressure data, compares it against threshold values, and automatically triggers window opening/closing actions. This closed-loop feedback mechanism enables the system to respond adaptively to changing environmental conditions while maintaining security.
3Productivity
If windows are opened for ventilation, then air flow is improved, but energy efficiency deteriorates due to heat loss
Solution Approach 1:
The system performs preliminary detection of draft conditions using air pressure sensors before opening windows. By anticipating the need for ventilation through draft detection, the system can open windows at optimal moments when outdoor temperature is favorable, thereby reducing subsequent heat loss while maintaining effective ventilation.
Solution Approach 2:
The system monitors and responds to changes in air pressure parameters to detect drafts. By detecting pressure differentials that indicate incoming air flow, the system can proactively open windows to enhance ventilation before significant temperature differences develop, thereby improving ventilation efficiency while minimizing energy loss through controlled timing.
4Ease of operation
If automated control is added to windows, then convenience is improved, but device complexity increases
Solution Approach 1:
The automated window system integrates multiple functions into a single unified device: air pressure sensing, draft detection, motor control, and user interface all work together in one system. This multi-functional integration, while increasing complexity, provides comprehensive automation that far exceeds the convenience of simple manual operation, justifying the added complexity through significant functional benefits.

Function Achieved in This Case
Enables efficient ventilation, energy savings, and enhanced security by automatically managing drafts and temperature, providing real-time feedback and user control, and integrating with smart home systems for seamless operation.
Implementation Method 1
at least two air pressure sensors in communication with a processor. If the window is open, based on signals from the air pressure sensors, the processor determines whether a draft is flowing through the window.
Implementation Method 2
the processor provides at least two temperature sensors in communication with the processor, whereby the processor can determine the temperature effect of opening the window if closed or the temperature effect of closing the window if open.

AI summary
An automated sliding window mechanism is disclosed. An automated sliding window mechanism includes a motor attached to a first component of a sliding window and configured to open and close the sliding window, a controller that controls the motor, and at least two air pressure sensors in communication with a processor. If the window is open, based on signals from the air pressure sensors, the processor determines whether a draft is flowing through the window. If the window is closed, based on signals from the air pressure sensor, the processor determines whether a draft would flow through the window if opened. The processor sends a signal to the controller to either open or close the window, depending on whether a user has elected to have a draft flow through the window. In a preferred embodiment, a system is provided with at least two automated windows.
