Inserting Member Fixing Device for Swinging Suppression and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding structures for inserting members, such as drivelines, fail to effectively suppress swinging and maintain sealing integrity due to external forces, leading to potential deformation of the kink guard and compromised sealing functionality.
Innovation Solution
An inserting member fixing device comprising a main body with a chuck portion, inner sealing portion, inserting member supporting portion, and movement restricting portion, which includes a communicating portion to maintain the inserting member in a linear shape and restrict movement, ensuring compatibility between swinging suppression and sealing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional holding structure with a kink guard is used to fix the inserting member, then the inserting member can be held in close contact with the fixing member, but the sealing member may be deformed under external forces causing loss of sealing function
Solution Approach 1:
The holding structure is divided into functionally independent components: the chuck member for holding, the inner sealing portion for sealing, the inserting member supporting portion for stability, and the movement restricting portion for constraint. This segmentation allows each component to perform its specific function without interfering with others, preventing deformation of the sealing member while maintaining reliability
Solution Approach 2:
The inserting member supporting portion acts as an intermediary between the inserting member and the movement restricting portion. It provides a stable support structure that prevents direct transmission of external forces to the sealing member, thereby maintaining both swinging suppression and sealing integrity
2Reliability
If the sealing member is positioned to seal the inserting member, then close contact and sealing are achieved, but the sealing member becomes vulnerable to deformation under radial loads
Solution Approach 1:
The inner sealing portion is positioned as an intermediary element between the inserting member and the external environment. It provides sealing contact with the inserting member while being structurally supported by the holding structure, preventing direct transmission of radial loads that would cause deformation
Solution Approach 2:
The inner sealing portion is designed as a flexible sealing element that can maintain close contact with the inserting member while accommodating minor movements. Its flexible nature allows it to conform to the inserting member surface for effective sealing without being rigid enough to resist radial loads directly

AI summary
This device is an inserting member fixing device to fix a linear inserting member to an insertion target, the inserting member fixing device comprising: a main body; a chuck portion; an inner sealing portion to be brought into close contact with an outer periphery of the inserting member; an inserting member supporting portion to support the inserting member; and a movement restricting portion to restrict movement of the inner sealing portion and the inserting member supporting portion. The inserting member supporting portion and the inner sealing portion are provided adjacent to each other in an axial direction of the inserting member, and a space is provided between the inserting member supporting portion and the inner sealing portion so that a main body-side end portion of the inserting member supporting portion is displaceable when the inserting member swings.
