Solution Overview

Problem

Current balancing machines require users to frequently interrupt the balancing process to acquire information from the display system, leading to potential errors and inefficiencies in attaching counterweights, especially when dealing with multiple balancing positions.

Innovation Solution

A method that includes a display unit connected to a control unit, allowing users to view the position of the balancing device relative to balancing regions before moving it, enabling the user to decide the sequence and reducing the need for manual marking, with a sensor detecting position data and guiding the balancing device into the correct position for counterweight attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the user frequently checks the display system for balancing position information, then the user can acquire necessary information, but the balancing process is interrupted and time is lost

Engineering Contradiction:
Improveinformation acquisitionVSAvoidbalancing process time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent implements a feedback mechanism where the display system continuously provides balancing position information to the user during the operation. The control unit processes sensor data about the balancing device position and feeds back this information to the display, allowing the user to monitor progress without interrupting the workflow. This resolves the contradiction by enabling information acquisition while maintaining process continuity.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the user manually positions the balancing device based on display information, then the counterweight can be attached, but errors may occur in positioning accuracy

Engineering Contradiction:
Improvemanual positioningVSAvoidcounterweight attachment position
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical positioning with an automated control system. The control unit receives position data from sensors, processes this information, and automatically controls the balancing device movement to the correct position. This substitution of manual operation with automated control eliminates positioning errors while maintaining ease of operation through intuitive display guidance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The balancing device has self-positioning capability through integrated sensors and automated control. The device can detect its own position relative to the shaft, process this information, and automatically move to the correct balancing region without requiring manual intervention for precise positioning. This self-service mechanism ensures both ease of operation and high positioning precision.

Inventive Principle:
Principle #25Self-service

3Reliability

If the balancing device mobility is restricted by manually positioned end stops, then counterweights can only be attached in specified regions, but the user must manually position end stops and manage complexity

Engineering Contradiction:
Improvecounterweight attachment region controlVSAvoidend stop positioning system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical end stop system with an automated sensor-based position control system. Instead of using physical end stops that require manual positioning, the system uses sensors to detect the balancing device position relative to the shaft and the control unit automatically determines when the device is in the correct balancing region. This eliminates the complexity of manual end stop management while maintaining reliable region control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A balancing device for installing a counterweight in a specified shaft balancing region paired with a balancing plane includes a securing device which can be controlled via a control unit. The securing device has a first and a second receiving area for a counterweight or the shaft at a free end. A slot is arranged on the balancing device such that the balancing device can be moved along the shaft in the axial direction. The balancing device has a sensor for ascertaining the position of the balancing device relative to the shaft. The balancing device further includes a display unit which is connected to the control unit so as to exchange data and which is designed such that the position of the balancing device relative to the balancing region can be displayed.
