Integrated Display Measuring Head for Vehicle Chassis Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current measuring devices for motor vehicle chassis calibration require operators to be positioned on a wheel or below the vehicle to read measurement data, making the adjustment process inefficient and prone to errors.
Innovation Solution
A measuring head with rear- and front-facing image recording devices and an integrated display device, positioned centrally next to the vehicle, allows for reading measurement data and instructions from a convenient position next to or below the vehicle, enhancing readability and reducing the risk of incorrect adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is positioned on the measuring head for reading measurement data, then the measurement data can be read during adjustment process, but the display device occupies space and may interfere with the measurement process
Solution Approach 1:
The display device is integrated directly into the measuring head, combining the measurement and display functions into a single unit. This allows the operator to read measurement data directly at the measurement location without needing separate display equipment, thereby improving ease of operation during the adjustment process.
Solution Approach 2:
The display device acts as an intermediary between the measurement system and the operator, providing visual feedback of measurement data at the point of measurement. This enables the operator to monitor and adjust vehicle parameters in real-time without leaving the working position.
2Loss of information
If the operator positions themselves on a wheel or below the vehicle to read measurement data, then the measurement data is accessible, but the adjustment process becomes inefficient and error-prone
Solution Approach 1:
The measuring head provides self-service by incorporating its own display device that shows measurement data directly at the measurement location. This eliminates the need for the operator to move to specific positions or use separate display equipment, allowing continuous monitoring and adjustment from the working position, thereby improving productivity.
3Ease of operation
If the display device is integrated into the measuring head, then measurement data can be read from any position, but the measuring head structure becomes more complex
Solution Approach 1:
The display device is merged with the measuring head structure, integrating multiple functions (measurement and display) into a single compact unit. This reduces the need for separate components and simplifies the overall system architecture, making the measuring head more versatile without proportionally increasing complexity.

AI summary
A measuring head (10) for measuring the chassis of a motor vehicle (6) for arrangement laterally next to the motor vehicle (6) which is to be measured comprises at least one image capturing device (12a, 12b) which is designed to capture images of at least one measuring panel (8a, 8b) attached to a wheel (7a, 7b) of the motor vehicle (6), and at least one display device (22) which is integrated in the measuring head (10) and is designed to display graphics and/or alphanumeric characters. The at least one display device (22) is more particularly designed on a lateral face (11b, 11c) of the measuring head (10), said lateral face being oriented substantially parallel to a direction of view (B) of the at least one image capturing device (12a, 12b).
