Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing translational-rotational fittings for rotating elements are tailored to specific cross-sectional areas, necessitating different fittings for rotating elements with varying dimensions.
Innovation Solution
A rotating element design with a cuboid-shaped body and a translation-rotation fitting that includes a base plate and a rotating plate, allowing adjustable positioning of a positioning plate relative to the floor or ceiling, enabling collision-free movement across different cross-sectional areas by aligning imaginary boundary lines with adjacent edges, and utilizing holes or locking receptacles for secure attachment based on panel thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a translational-rotational fitting is tailored to a predetermined cross-sectional area of the rotating element, then collision-free movement is achieved for that specific size, but different fittings are required for rotating elements with different cross-sectional areas
Solution Approach 1:
The translation-rotation fitting is designed with adjustable positioning elements that can be positioned at different locations on the rotating element's circumference. This dynamic adjustability allows the fitting to adapt to various cross-sectional areas while maintaining collision-free movement through predetermined angular ranges, resolving the contradiction between reliability for specific sizes and adaptability to different sizes.
Solution Approach 2:
The fitting system incorporates variable parameters including adjustable positioning radii and configurable angular ranges. By changing these parameters based on the rotating element's cross-sectional area, the same fitting design can accommodate different sizes while ensuring collision-free operation, thus achieving both reliability and versatility.
2Reliability
If multiple translational-rotational fittings are provided for different cross-sectional areas, then each fitting is optimized for its specific size, but device complexity and inventory requirements increase
Solution Approach 1:
A universal translation-rotation fitting design is created that can serve multiple functions across different rotating element sizes. The fitting incorporates adjustable positioning mechanisms and configurable angular ranges, allowing a single fitting type to be optimized for various cross-sectional areas, thereby reducing device complexity and inventory requirements while maintaining reliable performance.
Solution Approach 2:
The fitting system is segmented into modular components with independent adjustable features. This segmentation allows customization of the fitting's positioning and angular parameters without requiring completely different fitting designs, reducing the number of unique fitting types needed while maintaining optimized performance for each application.
3Adaptability or versatility
If panels with different material thicknesses are attached to the rotating element body, then the width and depth of the rotating element change, but the fitting must be repositioned to maintain collision-free movement
Solution Approach 1:
The fitting system incorporates pre-calculated positioning options that account for different panel thicknesses. By providing predetermined positioning locations that are pre-determined to work with various thickness configurations, the system simplifies the assembly process while maintaining adaptability to different panel dimensions.
Solution Approach 2:
A positioning plate or intermediary component is introduced between the fitting and the rotating element body. This intermediary provides adjustable positioning capabilities that accommodate different panel thicknesses, simplifying the overall assembly process while maintaining the ability to adapt to various configurations.
