Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only front window photos are used for hub identification, then the identification process is simple, but the identification accuracy is low leading to frequent misidentification
Solution Approach 1:
The patent combines multiple identification methods (front window photo recognition, dimensional measurement, and weight measurement) into a unified identification system. The processor integrates data from the photo taking device, electronic belt scale, and contact position sensors to comprehensively determine hub type, eliminating reliance on a single method and achieving accurate identification even for similar hub types.
Solution Approach 2:
The patent introduces an electronic belt scale and contact position sensors as intermediary measurement devices between the hub and the identification system. These intermediaries provide objective dimensional and weight data that supplement visual identification, serving as reliable mediators to confirm hub type and eliminate misidentification.
2Device complexity
If manual operation is used for hub identification, then device complexity is low, but productivity is reduced and misprocessing occurs
Solution Approach 1:
The patent implements an automatic identification system where the hub itself provides measurement data through self-contact with the contact position sensors during conveyance. The electronic belt scale automatically weighs the hub, and the contact position sensors automatically record dimensional data without manual intervention, enabling the system to serve itself and achieve high productivity.
Solution Approach 2:
The patent replaces manual mechanical identification operations with an automated system comprising photo taking devices, electronic scales, contact position sensors, and a processor. This mechanical-to-automated substitution eliminates human labor in the identification process while maintaining system simplicity through standardized components.
3Measurement precision
If dimensional measurement and weighing are added to photo identification, then identification accuracy is improved to 100%, but device complexity increases
Solution Approach 1:
The patent designs components with multiple functions to reduce overall system complexity. The electronic belt scale serves both as a conveyor support and a weight measurement device. The contact position sensors simultaneously measure multiple dimensional parameters (inner diameter, outer diameter, width) during a single hub passage. This multi-functionality allows accurate identification without proportionally increasing device complexity.
Solution Approach 2:
The patent employs dynamic measurement where the contact position sensors are driven by servo motors to contact different positions of the moving hub during conveyance. This dynamic approach allows dimensional measurement without stopping the hub, integrating measurement functions into the existing conveyance process and avoiding additional complex stationary measurement structures.
