Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peelable cylindrical layers are used to adapt to different cable diameters, then adaptability to different cable sizes is improved, but the complexity of assembly increases and reliable repositioning becomes difficult
Solution Approach 1:
The feedthrough unit is divided into multiple peelable cylindrical layers that can be separately removed to adapt to different cable diameters. Each layer can be independently peeled off in a controlled manner, transforming a complex assembly problem into a simple sequential removal process.
Solution Approach 2:
The cable entry opening is pre-configured with ribs and recesses that guide the peeling process. These pre-formed structural features enable the layers to be peeled back in a predetermined sequence and manner, ensuring proper positioning without requiring complex assembly steps during installation.
2Adaptability or versatility
If multiple peelable layers are used for cable adaptation, then adaptability to different cable diameters is improved, but the number of installation steps increases
Solution Approach 1:
The feedthrough unit transitions from a static multi-layer structure to a dynamically adjustable configuration. The layers are designed to be peeled back progressively during a single installation operation, allowing the opening diameter to dynamically adapt to the specific cable size being installed without requiring multiple separate installation steps.
Solution Approach 2:
The cable entry device performs its own adaptation function through the peelable layers mechanism. During cable installation, the layers are peeled back to accommodate the cable diameter, and the same structural features (ribs and recesses) that guide the peeling process also automatically position and seal around the cable, eliminating the need for separate positioning and sealing steps.
3Force
If corrugated layers are used to reduce contact area, then sealing pressure requirement is reduced, but the complexity of ensuring proper seal increases
Solution Approach 1:
The feedthrough unit employs corrugated cylindrical layers that function as flexible sealing elements. The corrugation pattern creates a labyrinthine seal path that conforms to the cable surface, reducing the required sealing pressure while the pre-formed ribs and recesses ensure proper alignment and contact, simplifying the sealing process.
4Adaptability or versatility
If separated layers are used for cable entry, then adaptability to different cable diameters is improved, but reliable repositioning and sealing becomes difficult
Solution Approach 1:
The cylindrical layers feature asymmetric corrugation patterns and non-uniform wall thickness distributions that create directional sealing forces. When the layers are peeled back and repositioned, the asymmetric geometry ensures they settle into a unique, reliable sealing configuration against the cable surface, preventing misalignment and ensuring consistent seal quality across different cable diameters.
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 system provides improved adaptability and sealing efficacy by ensuring precise positioning and alignment of layers, reducing the risk of oversized openings and enhancing the sealing effect, while simplifying the installation process.
Implementation Method 1
The feedthrough units are generally formed from an elastic material for mounting within an opening of the clamping device, and allow for elastic adaptation to a cable of a specific size.
Implementation Method 2
Compressible feedthrough units can be arranged in the opening of the clamping device; these units are deformed by clamping the clamping device, thus sealing the wires, cables, or pipes passing through them.

AI summary
The invention relates to a cable entry with a frame-shaped clamping device for attaching the cable entry (1) to a wall, and at least one feedthrough unit (3) for passing cables, wires, or pipes through an opening in the wall. The feedthrough unit (3) comprises a clamping element (4) with at least one first feedthrough opening (5) in the axial direction (x), wherein the clamping element (4) can be subdivided along the first feedthrough opening (5) into a first clamping half (6) and a complementary second clamping half (7). A sealing element (8) can be mounted in the first feedthrough opening (5), which, in an assembled state, has a second feedthrough opening (9) extending in the axial direction for inserting the cable, wire, or pipe. The sealing element (8) comprises several stackable layers, so that the second feedthrough opening (9) can be adapted to different diameters.
