Solution Overview

Problem

Existing sealing systems for cables, wires, or pipes through partition walls face challenges in efficiently detecting leakage and are costly due to complex manufacturing processes and potential clogging issues, leading to increased waste and malfunction risks.

Innovation Solution

A sealing system comprising insert blocks with fluid-permeable layers that form a communication system, allowing pressurized fluid to be directed through the blocks for efficient leakage detection, connected to a gauge for pressure loss measurement, and using polymer materials for durability and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sealing systems use compressed air, manometer, or double bulkhead systems for pressure testing, then leakage detection is possible, but the system becomes expensive and inconvenient

Engineering Contradiction:
Improveleakage detection capabilityVSAvoidtesting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insert blocks incorporate permeable layers that allow fluid to pass through when defective, creating a simple yet effective leakage detection mechanism. This porous material approach enables direct pressure testing without complex testing equipment, resolving the contradiction between reliable leakage detection and system simplicity.

Inventive Principle:

2Reliability

If insert blocks with bores are used for pressure testing, then leakage can be detected, but manufacturing becomes difficult and costs increase

Engineering Contradiction:
Improveleakage detection capabilityVSAvoidinsert block manufacturing
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Instead of manufacturing complex bores through insert blocks, the invention uses permeable layers that can be more easily integrated into the block structure. This approach maintains leakage detection functionality while significantly simplifying the manufacturing process and reducing production costs.

AI summary

The present invention relates to an insert half 100 for sealing around a cable 2, pipe or wire. The insert half 100 comprising: a body 101 with a first end 101a and a second end 101b. A first side 102 intended to be arranged towards a corresponding first side 102 of a substantially identical insert half 100, forming an insert block 4. A groove arranged in the first side 102 and extending between the first and second end along an axis A. The body 101 of the insert half 100 comprises a fluid permeable layer 105 extending in a plane transverse to the longitudinal direction of the axis A. A plurality of insert blocks 100 may be arranged in a frame 3 for allowing cables, wires, or pipes to be arranged through a partition wall. The arrangement creates a network connection of permeable layers 105 through a plurality of insert blocks 4. The permeable layers 105 may be used for the detection of leakage through the application of a pressurized fluid thereto.
