Solution Overview
Problem
Conventional tailgate mounting systems face inaccuracies in loading position due to external mounting jigs, leading to degraded mounting quality, unmanaged quality history, and limited compatibility with various vehicle models, requiring additional facility investments for new vehicle models.
Innovation Solution
A system comprising X-direction and Y-direction regulation jigs, a tailgate loading and mounting robot, and a nut assembly robot that measures and adjusts the tailgate's position on a vehicle body, ensuring accurate mounting and reducing facility costs through standardized regulation arms for different vehicle models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an external mounting jig is used to attach the tailgate, then the mounting process can be automated, but the loading position accuracy is degraded
Solution Approach 1:
The patent introduces an intermediary measurement system consisting of detection sensors and a control unit that acts as a mediator between the automated mounting jig and the tailgate positioning. The detection sensors measure the actual position of the tailgate, and the control unit calculates correction values to compensate for positioning errors, thereby maintaining both automation and precision.
Solution Approach 2:
The patent implements a feedback mechanism where detection sensors continuously monitor the tailgate's position during the mounting process. The measured position information is fed back to the control unit, which then adjusts the mounting parameters to correct any deviations from the target position, ensuring high positioning accuracy while maintaining automation.
2Ease of manufacture
If an external mounting jig is used, then the mounting process can be standardized, but the quality history management is lost
Solution Approach 1:
The control unit records the measurement data and correction values generated during each mounting operation, creating a digital quality history. This feedback system not only manages quality information but also enables traceability and continuous improvement of the mounting process while maintaining standardization.
Solution Approach 2:
The control unit serves as an intermediary that bridges the standardized mounting process with quality management requirements. It collects, stores, and analyzes quality data from each mounting operation, enabling comprehensive quality history management without disrupting the standardized automated process.
3Manufacturing precision
If the mounting jig is designed for specific vehicle models, then the mounting precision can be optimized, but the adaptability to various vehicle models is reduced
Solution Approach 1:
The patent designs the mounting jig with universal features that can accommodate multiple vehicle models. The detection sensors and control unit provide model-specific adjustments and corrections, enabling the same mounting jig to achieve high precision across different vehicle models without requiring model-specific hardware configurations.
Solution Approach 2:
The control unit adjusts mounting parameters such as position coordinates, measurement points, and correction values based on the specific vehicle model being serviced. This parameter-based adaptability allows the mounting jig to maintain high precision for each model while remaining physically compatible with various vehicle types.
