Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable feedthrough devices require complex assembly processes, involve multiple parts, and often necessitate additional fastening means like screw sets, leading to increased installation effort and cost, while providing inadequate sealing and ease of use.
Innovation Solution
A cable entry device featuring a feedthrough frame with a closure body and frame cover that snap into place using tapered locking heads, eliminating the need for screws and simplifying assembly by allowing the frame cover to be installed without additional fasteners, ensuring a secure and sealed cable passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable feedthrough devices use multiple parts and additional fastening means like screw sets, then the sealing and mechanical strength are improved, but the assembly complexity and installation effort increase
Solution Approach 1:
The patent combines multiple separate components (frame, cover, sealing elements, and fastening means) into an integrated unit where the frame and cover form a unified structure with built-in sealing and fastening capabilities. The cover is directly connectable to the frame without requiring separate screw sets, merging the functions of structural support, sealing, and fastening into a single integrated assembly.
Solution Approach 2:
The frame and cover are designed as multi-functional components that simultaneously provide structural support, sealing, and fastening functions. The frame rear side integrates mounting capabilities and sealing elements, while the cover incorporates both protective and fastening features, eliminating the need for separate specialized components for each function.
2Strength
If traditional cable feedthrough devices use multiple parts and additional fastening means, then the mechanical strength is improved, but the installation time and cost increase
Solution Approach 1:
The patent merges the fastening function directly into the cover structure, which is directly connectable to the frame. This integration eliminates the need for separate fastening operations and multiple components, reducing installation steps while maintaining the mechanical strength required for secure cable passage.
Solution Approach 2:
The frame and cover are pre-configured with integrated fastening features and sealing elements during manufacturing. The cover is designed with built-in fastening capabilities that enable direct connection to the frame without requiring additional fastening means to be added during installation, thereby reducing installation time and complexity.
3Stability of the object's composition
If traditional cable feedthrough devices require alignment and screw fastening, then the connection stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent combines the alignment and fastening functions into a single integrated operation. The cover and frame feature complementary geometric shapes that guide automatic alignment during the connection process, and the built-in fastening mechanism secures the connection simultaneously as the cover is attached, eliminating separate alignment and fastening steps.
Solution Approach 2:
The frame and cover are designed with self-aligning features where the geometric configuration of the components guides them into proper alignment during assembly. The integrated fastening mechanism automatically secures the connection as the cover is attached to the frame, without requiring manual alignment or separate fastening operations by the installer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a more cost-effective, easier-to-assemble, and user-friendly cable feedthrough device with enhanced sealing capabilities, reducing installation complexity and space requirements while maintaining a secure cable connection.
Implementation Method 1
The locking heads, which are elastically deformable, are pressed into the closure openings and engage in this way
Implementation Method 2
The frame cover can be connected to the feedthrough frame with the locking heads pressed into the closure openings
