Split Plate Sleeve Assembly for Deformation-Free Cable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sealing cables, pipes, or wires passing through partitions often result in deformations due to welding and lack adaptability to different sizes and environments, necessitating complete sleeve replacement and compromising water tightness and fire safety.
Innovation Solution
A modular, openable sleeve system comprising split plates and sleeve elements that can be easily assembled and disassembled using screw means, allowing for customization of height and fastening methods, reducing deformation risks and enabling selective replacement of damaged parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect the sleeve to the partition or plate, then strong connection is achieved, but deformations are formed
Solution Approach 1:
The connection system is segmented into multiple components: split plate divided into halves, sleeve divided into sections, and separate seal element. This segmentation allows assembly without welding, eliminating deformation while maintaining connection strength through mechanical fastening.
Solution Approach 2:
A seal element is introduced as an intermediary component between the sleeve and partition/plate. This seal element provides both the sealing function and the mechanical connection function, replacing the need for welding and preventing deformations.
2Ease of manufacture
If standard sized sleeves are used, then manufacturing is simplified, but adaptability to different demands is reduced
Solution Approach 1:
The sleeve is divided into multiple separable sections and the plate into halves, allowing these standardized components to be recombined in different configurations to accommodate various sizes and requirements while maintaining manufacturing simplicity.
Solution Approach 2:
The connection system is made dynamic and adjustable through screw means and removable seal elements, allowing the same standardized components to adapt to different installation requirements, cable sizes, and partition configurations.
3Reliability
If complete sleeve replacement is required, then sealing reliability is maintained, but loss of time and resources increase
Solution Approach 1:
The seal is provided as a separate, replaceable element rather than being integral to the sleeve. This allows only the seal to be replaced when needed, maintaining sealing reliability while significantly reducing replacement time and avoiding the need to replace the entire sleeve assembly.
4Strength
If welding is used for connection, then structural integrity is improved, but water tightness and fire safety may be compromised
Solution Approach 1:
A seal element made from materials suitable for water tightness and fire safety requirements is introduced as an intermediary between the sleeve and partition/plate. This seal element maintains structural integrity through mechanical connection while ensuring water tightness and fire safety compliance.

AI summary
Combination of a plate and a sleeve (1, 34) to be received at an opening of a transition. The plate is a split plate (2, 35) formed of two plate parts, forming an opening when joined to each other. The sleeve (1, 34) has a through opening to be placed in line with the opening of the transition and the opening of the split plate (2, 35). Said through opening of the sleeve (1, 34) is adapted to receive a seal. The sleeve (1, 34) is formed of a number layers. Each layer is formed of two sleeve elements (3, 12, 19, 23, 36, 45, 52). Each sleeve element (3, 12, 19, 23, 36, 45, 52) used to form the layers of the sleeve (1, 34) has a general form by means of which an opening is formed when two sleeve elements (3, 12, 19, 23, 36, 45, 52) of each layer are brought together.
