Solution Overview

Problem

Pendulum supports for damping devices in motor vehicle torque transmission systems have high manufacturing and assembly complexity, leading to high costs.

Innovation Solution

A method involving cutting a metal sheet to form a crown shape with radially inward lugs, deforming it to create a central recess and planar peripheral collar, and fixing the crown on the collar, utilizing the previously discarded central cutout to reduce material loss and costs, while allowing for rotation and secure fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional multi-component support structures are used, then mounting flexibility and damping effectiveness are improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvemounting flexibilityVSAvoidsupport structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the central ring and radially outer ring into a single integrated support structure formed from one plate. The plate contains both the central opening for the inner shaft and the radially outer opening for the outer shaft, eliminating the need for separate components and reducing assembly complexity while maintaining mounting flexibility

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single plate structure serves multiple functions simultaneously: it provides the central opening for mounting to the input shaft, the radially outer opening for mounting to the output shaft, and the structural framework for supporting pendulums. This multi-functional design reduces the number of parts needed

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If traditional multi-component support structures are used, then mounting flexibility is improved, but manufacturing cost increases

Engineering Contradiction:
Improvemounting flexibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple support components into a single plate that can be manufactured as one piece, reducing the number of manufacturing operations, material waste, and assembly steps required, thereby lowering production costs while maintaining the flexible mounting capabilities

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate components are used, then assembly flexibility is improved, but assembly complexity increases

Engineering Contradiction:
Improveassembly flexibilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support structure is merged into a single integrated plate that requires fewer assembly operations. The plate is formed with all necessary openings and mounting features during manufacturing, eliminating the need to assemble multiple separate components and reducing assembly complexity

Inventive Principle:
Principle #5Merging (Combining)
