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.

Innovation Solution

A rotary disc balancing simulation mass that simulates the mass of multiple components, attaching to fewer features than the number it simulates, and can be repositioned to cover all attachment points, allowing for faster and more accurate balancing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

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

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

Solution Approach 1:

The patent uses a simulation mass that replicates the combined mass characteristics of multiple rotary components rather than using individual dummy masses for each component. This copying approach maintains balancing accuracy while reducing the number of separate attachment operations required, thereby reducing time consumption.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulation mass combines the mass effects of multiple rotary components into a single integrated balancing element. By merging multiple mass simulations into one component, the patent reduces the number of attachment features needed and simplifies the balancing procedure, directly addressing the time consumption issue.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If individual dummy masses are used to simulate each rotary component, then the balancing precision is maintained, but the device complexity and number of attachments increase

Engineering Contradiction:
Improvebalancing precisionVSAvoidnumber of attachments
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The simulation mass integrates multiple mass simulations into a single device that attaches to the rotary disc through fewer attachment features than the number of simulated components. This merging reduces device complexity and the number of attachments while preserving balancing precision through proper mass distribution.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The simulation mass serves multiple functions simultaneously: it simulates the mass of multiple different rotary components and attaches to the disc through a reduced number of features. This multi-functionality maintains precision while reducing complexity.

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

3Reliability

If multiple attachment features are used to secure balancing components, then the reliability of attachment is improved, but the ease of operation and speed of balancing deteriorate

Engineering Contradiction:
Improveattachment reliabilityVSAvoidease of balancing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By combining multiple mass simulations into one simulation mass that uses fewer attachment features, the patent reduces the number of attachment operations required. This improves ease of operation and speeds up the balancing process while maintaining sufficient attachment reliability through the consolidated design.

Inventive Principle:
Principle #5Merging (Combining)

4Measurement precision

If the number of attachment features matches the number of rotary components, then the accuracy of mass simulation is improved, but the productivity and efficiency decrease

Engineering Contradiction:
Improvemass simulation accuracyVSAvoidbalancing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The simulation mass merges multiple mass simulations into a single component that attaches through fewer features than the number of simulated components. This approach maintains mass simulation accuracy through proper mass distribution while improving productivity by reducing the number of attachment operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The simulation mass creates a simplified copy of the combined mass characteristics of multiple components rather than creating individual copies for each component. This copying strategy maintains accuracy while improving efficiency by reducing the number of attachment features needed.

Inventive Principle:
Principle #26Copying
