Adjustable Stopper Locking Ring for Axial Position Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spacer devices in the automobile sector are prone to operator error during installation, which can lead to incorrect axial positioning and potential liquid-tightness issues, as they require manual manipulation of components that may inadvertently alter the position of the buffer head, and existing solutions fail to ensure complete fluid-tightness.
Innovation Solution
A self-adjusting spacer device comprising a bushing, pin, and locking member, where the pin is axially locked without direct manipulation, and the locking member is designed to rotate between adjustment and locking positions, preventing translational movement and ensuring liquid-tightness through a coupling mechanism that engages threaded portions to maintain the pin's position and prevent fluid ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual manipulation of the buffer head or auxiliary component is used to lock the axial position, then the device can be adjusted and locked, but operator error may inadvertently alter the axial position before locking, rendering the device ineffective
Solution Approach 1:
The device enables self-adjustment through the resilient element that automatically pushes the buffer head axially as the auxiliary component is rotated into place. The threaded engagement between the auxiliary component and buffer head converts rotational movement into precise axial positioning without requiring manual manipulation of the buffer head itself, thereby eliminating operator error while maintaining ease of operation.
2Adaptability or versatility
If the auxiliary component is capable of moving axially to allow adjustment, then the device can be positioned at different degrees of insertion, but operator error may inadvertently alter the axial position of the buffer head
Solution Approach 1:
The resilient element acts as an intermediary between the auxiliary component and the buffer head. It transmits the axial force generated by rotating the auxiliary component into the buffer head, ensuring precise positioning. The threaded engagement mechanism serves as another intermediary that converts rotational adjustment into controlled axial movement, allowing versatility while preventing operator error through mechanical guidance.
3Object-generated harmful factors
If small axial displacement is introduced to impart pretension and reduce vibrations, then vibration reduction is achieved, but a gap is created that may allow fluid ingress
Solution Approach 1:
The resilient element provides dynamic adjustment capability, allowing the buffer head to be pushed axially to create pretension that reduces vibrations. The element's elasticity enables it to maintain continuous contact and pressure between components, creating a sealed interface that prevents fluid ingress while sustaining the vibrational damping effect through controlled deformation.

Function Achieved in This Case
The solution reduces the risk of operator error by locking the pin axially without direct manipulation and ensures liquid-tightness by preventing axial movement of the locking member, thus maintaining the device's position and preventing fluid ingress, effectively reducing vibrations and ensuring the device remains sealed.
