Solution Overview

Problem

Existing methods for balancing rotary discs, such as installing component sets or using dummy masses, are time-consuming and prone to errors due to the complexity and number of components involved.

Innovation Solution

A rotary disc balancing simulation mass that simulates the mass of multiple components by attaching to fewer attachment features, allowing for quicker and more accurate balancing procedures by distributing mass circumferentially around the disc.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If component sets or individual dummy masses are installed on the rotary disc for balancing, then the balancing accuracy is improved, but the time consumption and complexity of the procedure increase

Engineering Contradiction:
Improvebalancing accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines multiple individual dummy masses into a single integrated balancing simulation mass that represents the collective mass of multiple rotary components. This merging approach maintains the required balancing accuracy while significantly reducing the time and complexity associated with installing and managing multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a simplified copy or representation of the actual rotary components through a balancing simulation mass. Instead of using the actual components or multiple individual dummy masses, a single simulation mass replicates the essential mass characteristics needed for balancing, thereby reducing procedural complexity while maintaining accuracy.

Inventive Principle:
Principle #26Copying

2Measurement precision

If multiple individual dummy masses are used to simulate components, then the balancing accuracy is improved, but the device complexity and number of components increase

Engineering Contradiction:
Improvebalancing accuracyVSAvoidnumber of components
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple individual dummy masses into a single integrated balancing simulation mass. This consolidation reduces the number of components from multiple separate masses to one unified component, thereby reducing device complexity while maintaining the ability to accurately simulate the mass characteristics of multiple rotary components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The balancing simulation mass serves multiple functions simultaneously: it represents the collective mass of multiple rotary components, provides the necessary balancing capability, and simplifies the overall system by reducing the number of components. This multi-functionality reduces device complexity while maintaining balancing accuracy.

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

3Measurement precision

If component sets are installed on the rotary disc for balancing, then the balancing accuracy is improved, but the ease of operation and installation are reduced

Engineering Contradiction:
Improvebalancing accuracyVSAvoidease of installation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent combines multiple installation operations into a single operation by using one integrated balancing simulation mass instead of multiple separate components. This merging approach maintains balancing accuracy while significantly improving ease of operation, as operators only need to handle and install one component rather than multiple separate masses.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The balancing simulation mass provides a simplified copy of the actual component system that is easier to handle and install. Instead of managing multiple individual components, operators work with a single simulation mass that replicates the essential mass properties, thereby improving ease of operation while maintaining balancing accuracy.

Inventive Principle:
Principle #26Copying
