Wheel Balancer Weight Error Correction via Stored Imbalance Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheel balancing systems often require repetitive 'chasing weights' due to operator errors, leading to excessive weight installation, time consumption, and potential unbalanced wheels, which can result in unjustified distrust of the system and costly repairs.
Innovation Solution
A wheel balancing system comprising a wheel imbalance measuring system, memory, user interface, and processing system that stores initial imbalance information, recalls it for residual measurements, and communicates weight placement and amount information to the user through a user interface, including location pointing systems to assist in accurate weight installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator installs weights based on initial imbalance information without error correction, then the balancing process is simple, but operator errors lead to excessive weight installation and time consumption
Solution Approach 1:
The system implements feedback by storing initial imbalance information and retrieving it during residual imbalance measurement. The processing system compares the residual imbalance with the stored initial imbalance to detect operator errors and provides corrective weight information, preventing the 'chasing weights' phenomenon and reducing time consumption.
2Manufacturing precision
If the system provides detailed weight placement guidance, then operator accuracy improves, but system complexity increases
Solution Approach 1:
The system performs self-verification by automatically comparing residual imbalance measurements with stored initial imbalance data. The processing system independently detects operator errors and generates corrective guidance without requiring additional external equipment or complex intervention mechanisms.
3Reliability
If the operator removes and restarts the balancing process, then error correction is achieved, but time consumption increases significantly
Solution Approach 1:
The system performs preliminary action by storing the initial imbalance information before the operator installs weights. This stored information is then used during residual measurement to provide error correction guidance, eliminating the need for the operator to remove weights and restart the process from scratch.

AI summary
A wheel balancing system may include a wheel imbalance measuring system, a memory system, a user interface, and a processing system. The processing system may be configured to cause initial imbalance information relating to an initial imbalance in a wheel assembly that was measured by the wheel imbalance measuring system to be stored in the memory system. The processing system may also be configured to recall the initial imbalance information from the memory system after a residual imbalance measurement of the wheel assembly by the wheel imbalance measuring system. The processing system may also be configured to cause the user interface to communicate weight information to the user about an amount and placement location of at least one weight needed to correct for the imbalance based on the initial imbalance information recalled from the memory system.
