Vehicle Console Slide Rail Damping for Smooth Low-Vibration Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle consoles suffer from increased assembly complexity and vibration transmission due to gaps in sliding mechanisms, leading to quality deterioration and poor operation feel.
Innovation Solution
A slide transfer device with a damper mounted inside a mounting hole to absorb vibrations and a bearing to support the sliding movement, along with a reducer to reduce rotation speed and compensate for shaft misalignments, using elastic materials with radial holes to minimize friction and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bearing is assembled to a moving rail to enable sliding movement, then the sliding function is achieved, but a gap is generated between the bearing and rail which transmits vibration and requires additional components
Solution Approach 1:
The patent introduces a damping element as an intermediary component between the bearing and the moving rail. This damping element fills the gap that would otherwise transmit vibration, while still allowing the bearing to perform its sliding function. The intermediary element thus resolves the contradiction by blocking the harmful vibration transmission path without interfering with the useful sliding movement.
Solution Approach 2:
The patent employs composite material structure by combining the bearing (metallic component for sliding) with a damping element (viscoelastic or polymeric material for vibration absorption). This composite approach allows the assembly to simultaneously achieve smooth sliding movement through the bearing while the damping material absorbs vibrations that would otherwise be transmitted through the gap.
2Object-affected harmful factors
If additional components are included to compensate for the gap in the bearing assembly, then vibration transmission is reduced, but the number of assembly processes and components increases
Solution Approach 1:
The patent merges the gap compensation function and vibration damping function into a single integrated damping element. Rather than adding separate components for gap filling and vibration damping, the invention uses one component that performs both functions simultaneously, thereby reducing the total number of components and assembly processes while still effectively reducing vibration transmission.
Solution Approach 2:
The damping element is designed with multi-functionality: it serves as both a gap compensator (maintaining proper clearance and alignment) and a vibration damper (absorbing vibrational energy). This universal component approach eliminates the need for multiple specialized components, simplifying the overall assembly while addressing the vibration problem.
3Ease of operation
If a bearing is assembled to a moving rail, then sliding movement is enabled, but the gap generates high operating force and deteriorates operation feeling
Solution Approach 1:
The damping element acts as an intermediary that fills the gap between the bearing and rail, eliminating the play or clearance that causes high operating forces. By providing continuous contact and support, the damping mediator ensures smooth force transmission during sliding operation, improving operation feeling without affecting the sliding function.
Solution Approach 2:
The patent changes the physical parameters of the interface between bearing and rail by introducing the damping element. This modifies the contact characteristics, friction properties, and force distribution in the sliding interface. The damping material's viscoelastic properties allow it to deform under load, maintaining consistent contact and reducing the peak forces required for operation.
