Solution Overview

Problem

Existing technologies fail to accurately visualize the up-down positional relationship of overlapping electronic components during mounting, making it difficult to detect errors in the mounting data.

Innovation Solution

An image data generation device that generates distinct visual aspects for overlapping electronic components based on their height positions, allowing operators to discern which components are mounted above or below each other, and highlights potential errors in positional relationships.

1Ease of operation

If multiple electronic components are displayed in the same aspect on the screen, then the display is simple and uniform, but the operator cannot determine the up-down positional relationship of overlapping components

Engineering Contradiction:

Improveease of determining up-down positional relationshipVSAvoiddisplay complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies color changes by displaying overlapping electronic components in different colors based on their up-down positional relationship. Specifically, components are displayed in a first color when they are in a first up-down position and a second color when they are in a second up-down position, enabling operators to visually distinguish the stacking order of components at a glance.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent applies asymmetry by displaying overlapping electronic components in different aspects ( orientations) according to their up-down positional relationship. Components in different stacking positions are rendered with different display aspects, creating an asymmetric visual representation that clearly indicates the hierarchical relationship between overlapping components.

Inventive Principle:

Principle #4Asymmetry

2Reliability

If height information is used to detect errors in overlapping components, then errors in the same layer can be detected, but errors in up-down positional relationships between different layers cannot be detected

Engineering Contradiction:

Improveerror detection capabilityVSAvoidinformation on up-down positional relationship

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces a visual display intermediary that translates height information and up-down positional relationships into graphical representations. By displaying overlapping components in different colors and aspects based on their positional relationships, the system provides an intuitive visual intermediary that reveals stacking order information without requiring operators to interpret raw height data.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback by providing visual information about the up-down positional relationships of overlapping components through color and aspect variations. This visual feedback enables operators to immediately understand the stacking order and identify potential errors in mounting data, allowing for real-time verification and correction.

Inventive Principle:

Principle #23Feedback

3Manufacturing precision

If components are displayed without visual differentiation, then the display process is simple, but operators cannot visually confirm correct mounting positions of overlapping components

Engineering Contradiction:

Improveaccuracy of mounting data verificationVSAvoidimage generation complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies color changes to differentiate overlapping electronic components based on their up-down positional relationships. Components are displayed in distinct colors according to their stacking positions, enabling operators to visually confirm correct mounting positions and detect potential errors in the manufacturing process.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent applies dimensionality change by representing three-dimensional stacking positions through two-dimensional visual differences in color and aspect. This allows the system to convey vertical positional information (height direction) through visual attributes on a flat display screen, enabling accurate verification of overlapping component positions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
