Solution Overview
Problem
Existing cable sealing and retaining devices require complex assembly processes and handling of small, intricate parts, making them time-consuming and prone to errors, with insufficient sealing or retaining performance often requiring disassembly of all components to identify defective parts.
Innovation Solution
A cable sealing and retaining device design where the sealing and fixation parts are accessible from the outside, allowing for separate handling and simplifying assembly, with a fixation part that can be securely attached to the sleeve portion without the need for internal threads or bolts, enabling easier installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing part and fixation part are integrated with internal threads and require bolt assembly, then reliable sealing and retaining are achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines the sealing part and fixation part into a single integrated component with external threads. The sealing part includes an outer surface with threading that directly engages with the sleeve portion, eliminating the need for separate fixation parts, internal threads, and bolt assemblies. This merging reduces the number of parts and simplifies the assembly process while maintaining reliable sealing and retaining functions.
Solution Approach 2:
The sealing part is designed to perform multiple functions simultaneously: it provides sealing through the seal ring, fixation through external threading engagement with the sleeve portion, and cable retention through the integrated structure. This multi-functional design eliminates the need for separate specialized components for each function, simplifying the overall device.
2Reliability
If multiple small parts (fixation part, seal ring, washer, bolt portion) are used, then reliable sealing and retaining are achieved, but handling and assembly become difficult and time-consuming
Solution Approach 1:
The patent merges the fixation part, seal ring, and washer into a single integrated sealing part. The sealing part includes an outer surface with threading, a passageway for the cable, and integrated features for sealing and fixation. This eliminates the need to handle and assemble multiple small separate parts, making the device much easier to install and maintain while maintaining reliable sealing and retaining performance.
3Volume of stationary object
If the fixation part is small and received within the passageway, then the sealing part size is reduced, but handling and assembly become more difficult
Solution Approach 1:
Instead of having the fixation part received within the passageway of the sealing part, the patent inverts the arrangement by providing external threading on the outer surface of the sealing part. This allows the sealing part to engage with the sleeve portion from the outside, making it easier to handle and assemble while avoiding the constraints of confined internal spaces.
4Reliability
If all parts must be disassembled to locate defective parts, then complete sealing and retaining functionality is ensured, but maintenance time and complexity increase
Solution Approach 1:
The patent segments the device into the sealing part and the sleeve portion as separate, easily detachable components. The sealing part with external threads can be independently removed from the sleeve portion for inspection, maintenance, or replacement without disassembling other parts. This segmentation facilitates easier locating and replacement of defective parts while maintaining complete sealing and retaining functionality.

Function Achieved in This Case
This design simplifies the assembly and handling of cable sealing and retaining devices, allowing for secure sealing and retention of cables with fewer parts, reducing the risk of errors and enabling easier maintenance by allowing the sealing part to be replaced without disassembling the fixation part.
Implementation Method 1
the seal ring is compressed and exerts a pressing force in radial direction towards the sealing part and the cable to provide a sealing therebetween

AI summary
The present invention relates to a cable sealing and retaining device capable of sealingly guiding and retaining a cable through an opening of the cable sealing and retaining device. The present invention provides an improved cable sealing and retaining device which allows a simple releasable fixation of a cable to the cable sealing and retaining device while the cable is sealingly guided through an opening provided with the cable sealing and retaining device. The cable sealing and retaining device (40; 60) comprises a sealing part (11) providing a passageway with an inner seal (14) through which a cable (2) is sealingly guidable, and an outer seal (15) arranged on an outer circumference of the sealing part (11). The cable sealing and retaining device (40; 60) comprises a fixation part (12) for retaining the sealing part (11) in longitudinal direction of the passageway; and a sleeve portion (47; 67) forming an opening (41; 61) for receiving the fixation part (12) and the sealing part (11) of the cable sealing and retaining device (40; 60). The sleeve portion (47; 67) provides a sealing section (42; 62) for co-operating with the outer seal (15) to perform a sealing therebetween. the cable sealing and retaining device (40; 60) is characterized by the fixation part (12) which provides fixation means (24) on its outer circumferential surface to fix the fixation part (12) to the sleeve portion (47; 67).
