Vibration-Damping Support Plate With Axial Locking Assembly

Solution Overview

Problem

Existing support plate designs for vibration filtering, such as those used for fans, heat exchangers, and condensers, face issues with cohesion between external and internal elements, particularly in the absence of external stresses, leading to potential slippage and reduced service life, and lack effective methods for classified recovery and recycling.

Innovation Solution

A support plate design featuring a peripheral, rigid outer element with a through hole and an inner, elastically deformable element, where the inner element is housed within the outer element, and active locking zones on the outer element prevent axial disengagement, ensuring secure assembly without bi-material molding or gluing, and allowing for elastic deformation to enhance vibration filtering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If simple fitting or gluing is used to join the inner element and outer element, then the manufacturing process is simple, but the cohesion between elements is insufficient leading to slippage under stress

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidcohesion between elements

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The support plate is divided into two separate elements (inner and outer) that are assembled together through a modular connection system involving protrusions and recesses, allowing simple manufacturing of individual components while achieving reliable assembly through mechanical interlocking

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner element is nested within the outer element, with the inner element's protrusions fitting into recesses of the outer element, creating a hierarchical assembly structure that maintains cohesion while allowing elastic deformation

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If bi-material molding is used to join the inner element and outer element, then the cohesion between elements is improved, but the manufacturing complexity and cost increase

Engineering Contradiction:
