Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional inspection tools (digital cameras, laser sensors) are used to identify object disposition, then geometric features can be detected, but the system requires additional tracking steps and repeated inspections for moving objects, reducing productivity
Solution Approach 1:
The system performs preliminary action by establishing a coordinate system and calculating the intersecting point of edges before the inspection process begins. This preliminary setup enables direct disposition determination without requiring subsequent tracking steps, thereby improving both measurement precision and productivity for moving objects
2Measurement precision
If fixtures are used to locate and hold the object during inspection, then object position can be maintained, but the fixtures are expensive, difficult to handle, and may not provide sufficient accuracy
Solution Approach 1:
The patent replaces the mechanical fixture system with an optical/electronic measurement system. Instead of using physical fixtures to locate and hold the object, the system uses sensors to detect edge positions and calculates the intersecting point to determine object disposition, eliminating the need for complex mechanical fixtures while improving accuracy
Solution Approach 2:
The system creates a digital representation of the object's geometric features by detecting edge positions and calculating the intersecting point within a coordinate system. This digital model serves as a virtual fixture, replacing physical fixtures and enabling accurate positioning without mechanical intervention
3Measurement precision
If the object moves during inspection, then continuous tracking is required to maintain accuracy, but this requires additional detection steps and may require repeating the inspection process
Solution Approach 1:
The system enables continuous disposition determination by establishing a reference coordinate system based on the intersecting point before movement occurs. This continuous reference framework allows the system to track moving objects without interrupting the inspection process, maintaining measurement precision while eliminating the need to repeat inspections

AI summary
A system for determining geometric disposition of an object within a coordinate system includes a processor and a sensor array. The sensor array includes a plurality of sensors oriented to scan a first edge and a second edge of an object for identifying a disposition of the first edge and the second edge within a coordinate system. The sensor array is electronically connected to the processor for signaling the identified disposition of the first edge and the second edge of the object within the coordinate system. The processor is programmed to calculate a location of an intersecting point of the first edge and the second edge. The processor calculates disposition of the object within the coordinate system from the calculated location of the of the intersecting point.
