Portable Wireless Wheel Alignment Diagnosis System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel alignment measurement systems require operators to frequently move between the vehicle and a fixed analysis station, leading to inefficiencies and increased time, as changes to one wheel alignment parameter often affect others, necessitating continuous adjustments and re-checks.
Innovation Solution
A portable diagnosis system with wireless communication and a control unit that allows real-time measurement and display of wheel alignment parameters on a portable device, enabling operators to make adjustments while monitoring changes directly at the vehicle, reducing the need for constant movement between the vehicle and the analysis station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed analysis station is used for measuring wheel alignment parameters, then measurement accuracy is ensured, but operator efficiency deteriorates due to frequent movement between the vehicle and the analysis station
Solution Approach 1:
The patent replaces the fixed mechanical analysis station with a portable diagnostic device that uses wireless communication to transmit and display measurement data. The portable device includes a control unit that receives signals from sensors mounted on the vehicle wheels and displays alignment parameters directly at the workspace, eliminating the need for operators to physically move to a fixed station for data retrieval.
2Manufacturing precision
If operators frequently check wheel alignment parameters at the fixed analysis station, then adjustment accuracy improves, but time consumption increases due to continuous movement
Solution Approach 1:
The portable diagnostic device acts as an intermediary between the measurement sensors and the operator. It wirelessly receives data from the sensors mounted on the wheels and displays the alignment parameters directly at the workspace, serving as a mobile interface that brings the analysis station's functionality to the operator's location without requiring physical movement.
3Reliability
If mechanical adjustments are made to wheel alignment parameters, then wheel alignment correctness improves, but the complexity of the adjustment process increases due to interdependencies between parameters
Solution Approach 1:
The system implements real-time feedback by continuously displaying wheel alignment parameters on the portable diagnostic device during adjustment operations. As operators modify suspension components or adjustment mechanisms, the sensors detect changes and immediately update the display, providing continuous feedback on how adjustments affect individual parameters and their interdependencies, enabling informed decision-making without leaving the workspace.
