Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for robot-guided automatic installation of add-on parts on vehicle bodies require vehicle type-specific installation devices and involve lengthy execution times due to precise alignment and correction processes.
Innovation Solution
A method using a dual reference point system to define the arrangement of body and add-on part hinge halves, allowing for universal installation with a positioning device that measures and corrects hinge positions, enabling rapid and accurate installation across multiple vehicle types without the need for precise part picking and multiple installation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional robot-guided automatic installation methods are used with vehicle type-specific installation devices, then installation precision can be maintained, but installation time increases and device complexity increases
Solution Approach 1:
The patent implements a universal installation device that can handle multiple vehicle types through a standardized reference point system. Instead of requiring separate vehicle type-specific installation devices, the system uses a common positioning approach with vehicle-specific reference point data, allowing one device to serve multiple functions across different vehicle models.
Solution Approach 2:
The patent performs preliminary measurement and calculation of correction values before the actual installation process. The system measures reference points on the vehicle body, calculates the necessary corrections for hinge half positioning, and prepares the positioning data in advance, which significantly reduces the time required during the actual installation execution.
2Manufacturing precision
If conventional alignment and correction processes are used, then installation accuracy is achieved, but the number of required installation devices increases
Solution Approach 1:
The patent creates a universal positioning system that eliminates the need for multiple specialized installation devices. By establishing a standardized reference point system that works across different vehicle types, the same installation device can be used for various vehicles, reducing the total number of devices required while maintaining alignment accuracy through calculated correction values.
Solution Approach 2:
The patent uses a reference point system that creates a digital model or map of the vehicle body geometry. This reference data serves as a template that guides the installation device, replacing the need for physical alignment tools and multiple specialized devices for different vehicle types.
3Manufacturing precision
If vehicle type-specific installation devices are used, then precise installation can be achieved, but setup time increases
Solution Approach 1:
The patent implements a universal installation device configured with vehicle-specific reference point data instead of requiring physically different devices for each vehicle type. This approach eliminates setup time associated with changing or reconfiguring specialized devices, as the same device can quickly adapt to different vehicles by loading the appropriate reference data.
Solution Approach 2:
The patent makes the installation system adaptable and dynamic by using programmable positioning based on reference point data. Rather than static, vehicle-specific hardware configurations, the system dynamically adjusts positioning parameters through software control, allowing rapid reconfiguration between different vehicle types without physical setup changes.
