Solution Overview
Problem
Existing sealing elements face challenges in secure mounting, orientation, and resistance to sliding out of cutouts, particularly in applications requiring high reliability and efficiency.
Innovation Solution
A sealing element design featuring a stabilizing surface orthogonal to its longitudinal extent, equipped with a retaining surface and securing elements that project from the stabilizing surface, enhancing retention and preventing sliding, with a preferred width and length ratio for improved stability and vibration damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sealing element design is used, then the structure is simple, but the sealing element cannot be securely retained in the cutout and has poor resistance to sliding out
Solution Approach 1:
The sealing element is divided into functionally distinct surfaces: a stabilizing surface for orientation and positioning, and a retaining surface with securing elements for preventing sliding out. This segmentation allows each surface to optimize its specific function, improving overall retention security without excessive complexity.
Solution Approach 2:
The invention adds a protruding dimension with securing elements that extend beyond the sealing element body into the cutout. This dimensional addition creates mechanical interlocking that significantly improves retention security while maintaining relatively simple overall structure.
2Reliability
If a sealing element without securing elements is used, then the manufacturing is simple, but the mounting security and resistance to sliding out are insufficient
Solution Approach 1:
The sealing element incorporates discrete securing elements as separate functional components on the retaining surface. This segmentation allows the securing elements to be optimized for mounting security while maintaining manufacturing simplicity through integrated molding or attachment of standardized components.
Solution Approach 2:
Securing elements are placed specifically on the retaining surface where they are needed for mounting security, rather than complicating the entire sealing element structure. This local quality approach improves mounting security without significantly increasing overall manufacturing complexity.
3Manufacturing precision
If the sealing element lacks a dedicated stabilizing surface, then the structure is simpler, but the orientation and positioning accuracy in the cutout are poor
Solution Approach 1:
A dedicated stabilizing surface is created with specific geometric properties (area, orientation, position) that are optimized solely for positioning and orienting the sealing element in the cutout. This local quality enhancement improves positioning accuracy without requiring complex modifications to the entire sealing element structure.
Solution Approach 2:
The stabilizing surface utilizes the cross-sectional dimension of the sealing element to create positioning features that engage with the cutout geometry, improving positioning accuracy in the transverse direction without adding longitudinal complexity.
4Reliability
If the securing elements do not project from the stabilizing surface, then the structure is simpler, but the resistance to sliding out of the cutout is reduced
Solution Approach 1:
Securing elements project protrudingly from the stabilizing surface in the longitudinal direction, creating mechanical interlocking with the cutout. This dimensional extension significantly improves sliding resistance while maintaining relatively simple securing element configuration through standardized protruding geometries.
