Solution Overview

Problem

Existing systems for sealing cable entries and pipe penetrations in moderate environments are often too costly and complex, requiring specific compression units and not economically justified for protected installations, where stringent tightness demands are less than in harsh environments.

Innovation Solution

A frame and module system that uses automatically compressing modules in two steps: initial compression when inserted into the frame and further compression when attached to an appliance, eliminating the need for a specific compression unit and allowing for easy assembly and use of standard modules, facilitating straight row mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard compression units are used to create tight seals, then sealing performance is improved, but device complexity and cost increase

Engineering Contradiction:
Improvesealing performanceVSAvoidcompression unit requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The module itself performs the compression function through its elastic material properties. The elastic module automatically compresses when inserted into the frame, creating the seal without requiring external compression units. This self-service approach eliminates complex compression mechanisms while maintaining reliable sealing performance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces expensive, complex compression units with simple, inexpensive elastic modules. These elastic modules are designed as single-use or limited-life components that provide adequate sealing for moderate environments, reducing overall system cost and complexity.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If expensive frames and modules are used for harsh environments, then tightness is improved, but cost increases for moderate environments

Engineering Contradiction:
ImprovetightnessVSAvoidcost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention applies different quality levels to different sealing scenarios. For moderate environments, simpler and less expensive elastic modules are used that provide adequate tightness without the overhead cost of harsh-environment specifications. This local quality approach matches the sealing capability to the actual environmental demands.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The elastic modules are designed with specific material parameters (elasticity, compression ratio) that are optimized for moderate environment applications. By adjusting these parameters, the system achieves cost-effective tightness appropriate for protected installations without requiring the enhanced parameters needed for harsh environments.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If specialized compression equipment is required, then sealing reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesealing reliabilityVSAvoidassembly simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The elastic module automatically performs the compression and sealing function upon insertion into the frame. No specialized compression equipment or complex assembly procedures are needed - the module self-compresses through its elastic properties, making assembly simple while maintaining reliable sealing.

Inventive Principle:
Principle #25Self-service

4Reliability

If non-standard modules are used, then tightness is improved, but adaptability deteriorates

Engineering Contradiction:
ImprovetightnessVSAvoidmodule compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The elastic modules are designed with standardized dimensions and interface features that allow them to be used across multiple frame configurations and applications. This universality enables the same module design to serve various cable types and sizes while maintaining adequate tightness, improving adaptability without sacrificing sealing reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention concerns a frame (1) for receiving one or more elastic modules (2) forming cable entries, pipe penetrations or the like. The frame (1) has a form automatically compressing the one or more modules (2) at mounting to an appliance (7). The compression is made in that the modules (2) are received in a central opening of the frame (1) formed by inclining walls (3) and that the overall dimension of the modules (2) received in the central opening is somewhat larger than the inner dimension of the central opening. The modules (2) protrude from the frame (1) and are therefore further compressed when the frame is mounted to the appliance (7).
