Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image-based determination is used to detect component presence, then visual inspection capability is provided, but detection accuracy deteriorates for certain component types
Solution Approach 1:
The patent introduces a component detecting sensor as an intermediary device to complement the imaging device. When the imaging device fails to accurately determine component presence (for certain component types), the system switches to or combines with sensor-based detection. This intermediary sensor provides an alternative detection mechanism that overcomes the limitations of pure visual inspection, thereby resolving the contradiction between visual inspection capability and detection accuracy.
2Device complexity
If a single determination method is used, then system complexity is reduced, but detection reliability deteriorates across varying component types
Solution Approach 1:
The patent implements a dynamic determination system that can switch between different detection methods based on component characteristics. The control device selects between image-based determination and sensor-based determination (or combines them) depending on the specific component type being detected. This dynamic adaptation allows the system to maintain high reliability across varying component types without requiring a permanently complex multi-method architecture for all scenarios.
3Device complexity
If camera-based detection is used for all components, then equipment simplicity is maintained, but detection accuracy worsens for components difficult to image
Solution Approach 1:
The patent creates a universal determination system that can handle diverse component types through multiple detection methods. The component supply device incorporates both an imaging device and a component detecting sensor, allowing the system to universally detect various component types (including those difficult to image) by selecting the appropriate method. This multi-functional approach maintains equipment simplicity through integrated control while achieving high detection accuracy across all component types.

AI summary
A component mounting machine includes an imaging device configured to image a supply position, to which a component is supplied from a component supply device, from above, a component detecting sensor configured to detect the component. A control device acquires component information related to the component supplied by the component supply device when a predetermined determination condition is established. Then the control device selects from multiple processing including first determination processing for determining presence or absence of a component shortage of the component supply device by determining presence or absence of the component at the supply position based on a captured image, and second determination processing for determining presence or absence of a component shortage of the component supply device by detecting the presence or absence of the component at the supply position by the component detecting sensor.
