Steering Column Auto-Alignment for Instrument Panel Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for setting and auditing the position of a steering wheel and steering column in vehicles are prone to errors due to manual operator dependence, tool variability, and potential damage, which affect the alignment and visibility of the instrument panel, especially during the manufacturing process.
Innovation Solution
A control system that includes a motor and controller to automatically adjust the steering column and wheel to a predetermined 'Clear Vision' position based on the visibility of the instrument panel, activated only during factory mode, eliminating manual intervention and minimizing manufacturing cycle time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual operator dependence is used for setting and auditing steering wheel position, then flexibility and adaptability are maintained, but alignment precision and consistency deteriorate due to operator errors and tool variability
Solution Approach 1:
The system performs self-alignment by automatically commanding the motor to move the steering column to a predetermined position based on instrument panel visibility requirements, eliminating the need for external manual operators and tools while maintaining high alignment precision
Solution Approach 2:
The manual mechanical adjustment process is replaced with an automated electronic control system that uses a controller to command a motor, substituting human operators and manual tools with an automated electromechanical system for superior precision and consistency
2Productivity
If manual adjustment methods are used, then device complexity is low, but manufacturing time increases due to operator dependence and potential rework
Solution Approach 1:
The system executes the alignment action automatically as part of the ignition on/off cycle, performing the positioning task in advance during normal vehicle operation rather than requiring separate manual adjustment steps, thereby reducing manufacturing cycle time without adding complex automation infrastructure
3Reliability
If manual operator adjustment is used, then ease of operation is maintained, but reliability deteriorates due to potential damage and alignment errors
Solution Approach 1:
The system protects itself by automatically controlling the motor to precisely position the steering column without manual intervention, eliminating the risk of operator-induced damage while maintaining operational simplicity through automated execution during ignition cycles
Solution Approach 2:
The system uses the completion of ignition on/off cycles as a trigger signal to execute alignment, creating a feedback-based automated control mechanism that ensures reliable positioning without requiring continuous manual monitoring or adjustment

AI summary
A vehicle is able to be set to operate in a factory mode (as opposed to a normal mode) in which certain features are disabled, such as an alarm system, a power liftgate, etc. This allows assembly workers to assemble, test, and calibrate the vehicle without various systems in the vehicle being undesirably activated. While in the factory mode, the vehicle can accomplish multiple ignition on/off cycles while being tested or driven between stations. A steering column and connected steering wheel are provided in the vehicle, and are situated between an instrument panel and a front seat. In response to the ignition completing an on/off cycle, a controller commands a motor to move the steering wheel and steering column to a predetermined position that is based on a visibility of the instrument panel relative to the steering wheel and steering column.
