Movable Duct Fixing Collar for Sanitary Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of built-in sanitary installations is complex due to reduced accessibility, diversity of configurations, and the number of parts used, making it difficult to facilitate the fixing of pipes and alignment with the drainage network.
Innovation Solution
A fixing device with movable duct fixing elements that form a collar for easy assembly and adjustment, allowing for independent movement and locking of duct elements on a support frame, enabling flexible positioning and connection to the drainage network without requiring the frame to be moved during gluing and fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support frame is fixed in position during installation, then the structural stability is improved, but the accessibility for pipe fixing and alignment is worsened
Solution Approach 1:
The collar is divided into two separate elements (first collar element and second collar element) that can move independently relative to each other along the support frame. This segmentation allows the installer to access and position the pipe between the two elements without needing to move the entire support frame, thereby maintaining structural stability while improving accessibility during installation.
Solution Approach 2:
The collar elements are designed to be movable along the support frame rather than fixed. The first and second collar elements can slide independently to different positions, allowing dynamic adjustment during the installation process to accommodate pipe alignment requirements while the support frame remains stationary and stable.
2Adaptability or versatility
If multiple parts are used for duct fixing, then the adaptability to different configurations is improved, but the device complexity is worsened
Solution Approach 1:
The collar elements are designed with universal functionality to accommodate different pipe diameters and configurations. The same first and second collar elements can adapt to various duct sizes and orientations through their independent movement along the support frame, eliminating the need for multiple specialized fixing components for different configurations.
Solution Approach 2:
The invention combines the functions of multiple potential fixing components into a single integrated collar system. The first and second collar elements working together replace what would traditionally require separate fixing devices, brackets, and fasteners, thereby reducing overall device complexity while maintaining adaptability.
3Manufacturing precision
If the collar elements are fixed in position, then the manufacturing precision is improved, but the ease of operation during installation is worsened
Solution Approach 1:
The collar elements are designed with movable characteristics that allow adjustment during installation while maintaining precise positioning when installed. The elements can slide along the support frame to accommodate alignment variations, then be secured at the desired position, combining ease of operation with manufacturing precision.
Solution Approach 2:
The collar elements are pre-designed with guide features and positioning mechanisms that ensure precise alignment during the adjustment process. This preliminary design of positioning features allows the elements to be easily adjusted to the correct position while maintaining high manufacturing precision in the final installed state.
