Tool-Free Cable Control Line Gasket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gasket solutions for sealing cable control lines in engine compartments are labor-intensive, often requiring specialized tools and resulting in high service costs due to potential damage and inefficiencies in mounting and maintenance.
Innovation Solution
A gasket composed of two parts: an elastic rubber component with encircling grooves and a slider with bridges and mounting clips, facilitated by an air cushion for easy installation, along with noise- and heat-insulating agents, allowing for secure and rapid mounting without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tool is used to fit the gasket in the opening, then the gasket can be mounted securely, but the process becomes labor-intensive and requires specialized tools
Solution Approach 1:
The gasket is designed with self-centering features including an encircling groove that engages with the opening and mounting clips that automatically position the gasket correctly, eliminating the need for specialized tools and reducing labor intensity while maintaining secure mounting
2Reliability
If the gasket is made with exact fit and low tolerances, then gas-tight and liquid-tight sealing is achieved, but the gasket can be damaged during assembly
Solution Approach 1:
The gasket is divided into functional segments: a compliant sealing body made of soft stable rubber that provides tight sealing, and a separate slider component with mounting clips that provides structural support and protection during assembly, preventing damage to the sealing portion
Solution Approach 2:
The slider acts as a protective cushion during assembly operations, absorbing mechanical stresses and protecting the precisely toleranced sealing surfaces from damage while maintaining the exact fit required for gas-tight and liquid-tight sealing
3Device complexity
If the mounting clips are positioned close to the slider, then the structure is compact, but insufficient force can be exerted on the bottom of the gasket
Solution Approach 1:
The mounting clips are positioned at an optimized distance from the slider to provide sufficient leverage and mounting force while maintaining a compact overall structure through three-dimensional space utilization and efficient force transmission geometry
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
Enables quick, secure, and tight sealing of cable control lines in engine compartments with reduced service costs and improved durability, facilitating easy assembly and maintenance.
Implementation Method 1
There is an air cushion between the surface of the gasket and the slider that facilitates mounting
Implementation Method 2
It is advantageous here if the side of the gasket facing the wall is chamfered so that the gasket can be drawn more easily into the passage in the wall. It is also advantageous to introduce a noise-damping and/or a heat-insulating agent into the cavity that exists between the slider and the gasket.
Implementation Method 3
It is also advantageous to introduce a noise-damping and/or a heat-insulating agent into the cavity that exists between the slider and the gasket.

AI summary
A gasket for the passage of at least one cable control line in the wall of an engine compartment, principally the engine chamber of motor vehicles, with the gasket being premounted on the cable control line and closing the engine compartment opening for the cable control line quickly and tightly, and having a slider. The gasket has a circumferential groove for the wall of the engine compartment, a recess for a slider, at least one opening for the cable control line, and at least one mounting groove for mounting clips of a slider. The slider has bridges and mounting clips that engage in the mounting grooves of the gasket. There is also a blocking lip on the gasket, which in the mounted state prevents the slider from sliding back, and a pull device on the slider.
