Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual input operations are performed in the inspection device when substitute components are used, then the inspection device can be updated to recognize substitute components, but working efficiency is degraded and input mistakes may occur

Engineering Contradiction:

Improveinspection accuracyVSAvoidworking efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The inspection device automatically detects substitute components through image recognition and autonomously updates its component database without requiring manual operator input. The system serves itself by comparing captured images against known component patterns and automatically registering new substitute component types, thereby eliminating manual operations while maintaining inspection accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where the inspection device captures images of mounted components, compares them with database patterns, and uses the comparison results to automatically update the component database. This closed-loop feedback enables the system to learn and adapt to substitute components automatically, improving both reliability and productivity

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

Engineering Contradiction:

Improvecomponent substitution capabilityVSAvoidinput accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces manual mechanical input operations with an automated image recognition and processing system. The inspection device uses optical imaging and computer vision algorithms to automatically identify and register substitute components, eliminating the need for manual data entry and thereby removing the source of human input mistakes while maintaining adaptability to component substitutions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If automatic data update is implemented in the inspection device, then working efficiency is improved and input mistakes are reduced, but system complexity increases

Engineering Contradiction:

Improveworking efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The inspection device integrates multiple functions into a single system: it performs both the original inspection function and the additional function of automatically detecting and registering substitute components. By making the inspection device multi-functional, the system achieves automatic data update capability without adding separate dedicated systems, thereby limiting the increase in overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed are a component mounting line and a component mounting method where it is not necessary for an operator to perform an input operation in an inspection device when substitute components are used in a component mounting device. When substitute components are mounted in place of one type of components at the mounting positions on the substrate PB, a component mounting device 4 creates substitute component related data including information specifying the substrate PB on which substitute components are mounted and the mounting positions at which the substitute components on the substrate PB are mounted and information indicating the types of substitute components and transmits the substitute component related data to the post-mounting inspection device. The post-mounting inspection device 5 specifies the substrate PB on which the substitute components are mounted and the mounting positions at which the substitute components on the substrate PB are mounted on the basis of the substitute components related data received from the component mounting device 4 and changes image data 45 (inspection data) for the components P at the mounting positions at which the substitute components are mounted to data corresponding to the types of the substitute components.
