Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for guiding lines through openings in walls face challenges in simplified assembly and secure sealing, particularly in ensuring the final element is securely tensioned against the wall surface.
Innovation Solution
The device employs an elastic deformation mechanism where the pipe element and/or final element can be axially deformed to generate a pressing force against the wall, using a coupling section with elastic deformable coupling elements and a cuff for sealing, allowing for easy assembly and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manually applied clamping force is used between closure elements to secure the device against the wall, then the device can be fixed in position, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The pipe element is designed to generate its own clamping force through elastic deformation during insertion. As the pipe element is pushed through the wall opening, it elastically deforms and automatically generates a pressing force against the closure elements, eliminating the need for manual clamping operations and complex adjustment mechanisms
Solution Approach 2:
The pipe element utilizes elastic deformation as a parameter change mechanism. By controlling the degree of elastic deformation during insertion, the system automatically generates the required clamping force, transforming the insertion process into a self-regulating fixation mechanism that simplifies assembly while ensuring reliable fixation
2Reliability
If expansion bodies are used to generate clamping force, then secure fixation is achieved, but the device structure becomes more complex with additional components
Solution Approach 1:
The invention extracts the clamping force generation function from separate expansion body components and integrates it directly into the pipe element itself. The pipe element's elastic deformation capability is utilized to generate the required clamping force, eliminating the need for distinct expansion bodies and reducing the overall component count
Solution Approach 2:
The clamping function and the structural pipe element are merged into a single integrated component. The pipe element simultaneously serves as the structural conduit and the active element that generates clamping force through elastic deformation, reducing component count and simplifying the overall device structure
3Reliability
If multiple closure elements are arranged on opposite sides of the wall with manual clamping, then secure sealing is achieved, but the installation time and effort increase
Solution Approach 1:
The system performs self-service by automatically generating the clamping force required for sealing through the elastic deformation of the pipe element during insertion. This eliminates the need for manual clamping operations on both sides of the wall, significantly reducing installation time and effort while maintaining sealing quality
Solution Approach 2:
The pipe element is pre-designed with elastic deformation characteristics that will automatically generate the required clamping force during the insertion process itself. This preliminary design of the deformation behavior ensures that the sealing action occurs automatically as part of the installation process, rather than requiring separate manual clamping steps
