Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complete screen is used, then the screen provides full coverage, but the screen lacks stability and is challenging to place in modern window constructions
Solution Approach 1:
The screen frame incorporates sliding corner parts that allow dynamic adjustment of the screen circumference. The corner parts can slide along the profile sections to accommodate different window opening sizes, enabling the screen to adapt its dimensions for easy placement while maintaining stability through the locking mechanism that secures the adjusted position.
Solution Approach 2:
The screen frame allows changes in its circumferential parameter through the sliding corner parts. By adjusting the position of the corner parts along the profile sections, the screen can modify its circumference to match different window opening dimensions, solving the problem of placing a complete screen in various window constructions.
2Adaptability or versatility
If the screen frame circumference is fixed, then the screen structure is simple, but the screen cannot adapt to various window opening sizes
Solution Approach 1:
The screen frame is segmented into modular components with sliding corner parts that can independently adjust along the profile sections. This segmentation allows each corner part to be positioned independently to match the specific dimensions of the window opening, providing adaptability while keeping the overall structure relatively simple and manageable.
Solution Approach 2:
The corner parts are designed as dynamic elements that can slide along the profile sections and lock at different positions. This dynamic capability enables the screen frame to adapt to various window opening sizes without requiring a completely different frame structure for each size, thus improving versatility while controlling complexity.
3Ease of operation
If sliding corner parts are added to allow circumference adjustment, then the screen can be placed on building frames, but the device complexity increases
Solution Approach 1:
The sliding corner parts incorporate a self-locking mechanism that automatically secures the corner part at the desired position along the profile section. This self-service feature eliminates the need for additional fastening operations or complex adjustment mechanisms, simplifying the installation process while keeping the corner part design relatively simple.
Solution Approach 2:
The corner part acts as an intermediary element between the profile sections and the screen mesh. It provides the necessary adjustment capability while maintaining a simple structure that integrates smoothly with the existing screen frame components, thus improving ease of installation without significantly increasing overall device complexity.
