Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional inspection methods are used for wheel blanks, then the inspection process is simpler, but the accuracy of determining load points and minimizing inclination is insufficient, leading to potential tool damage and reduced manufacturing precision
Solution Approach 1:
The inspection process is divided into distinct stages: path acquisition, depth measurement, and load point localization. Each stage processes specific data independently, allowing for precise measurement without overwhelming system complexity. The depth sensor captures depth values at multiple positions along the scanning path, which are then processed separately to determine load points and inclination.
Solution Approach 2:
The system transitions from traditional 2D imaging to 3D depth measurement by introducing a depth sensor that captures depth values. This dimensional enhancement allows for more accurate determination of load points and inclination by analyzing depth variations across the wheel blank surface, resolving the contradiction between measurement precision and device complexity.
2Manufacturing precision
If a depth sensor and computing control module are used to perform path acquisition, depth measurement, and load point localization, then manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The system performs path acquisition and depth measurement before the actual processing of the wheel blank. By pre-determining the load points and inclination through depth sensor scanning and computation, the system ensures that subsequent processing operations can be performed with high precision without requiring complex real-time adjustments during manufacturing.
Solution Approach 2:
The invention replaces traditional mechanical measurement methods with a depth sensor-based optical/electronic system. The depth sensor non-contactively measures depth values, and the computing control module processes this data to determine load points and inclination, eliminating the need for complex mechanical measurement apparatus while improving manufacturing precision.
3Reliability
If load points are not accurately determined, then the inspection process is faster, but tool collisions may occur during processing, reducing reliability
Solution Approach 1:
The depth sensor systematically scans the wheel blank along predetermined paths and automatically captures depth values at multiple positions. The computing control module independently processes this data to determine load points and inclination without requiring manual intervention or additional external equipment, achieving reliable results efficiently through self-contained operation.

AI summary
A wheel blank inspection device is for inspecting a wheel blank and includes a depth sensor and a computing control module electrically connected to the depth sensor. The computing control module executes a path acquisition process, a depth measurement process and a load point localization process. The path acquisition process is controlling the depth sensor to scan the wheel blank, obtaining a center fitted to a flange of the wheel blank, and calculating at least one detection path based on the center. The depth measurement process is controlling the depth sensor to scan the flange of the wheel blank according to the at least one detection path to capture depth values of the flange. The load point localization process is obtaining load points and information of relative positions of the load points with respect to a reference point of the wheel blank based on the depth values.
