Solution Overview

Problem

Miniaturized coil components face increased risk of cracking due to external forces when inclined on printed circuit boards, and there is a need to easily recognize inclination for proper mounting and stability.

Innovation Solution

A coil component design featuring a body with opposing surfaces, a support substrate, and recognition patterns that extend from one edge to another, allowing for identification of direction and inclination using high-precision cameras to distinguish between organic and metal materials, facilitating accurate mounting and reducing the risk of cracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the coil component is miniaturized, then the size is reduced, but the risk of cracking due to external force increases

Engineering Contradiction:

Improvesize of coil componentVSAvoidrisk of cracking

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by providing a support substrate embedded in the body that spans across the coil structure. This support substrate acts as a reinforcing element that prevents cracking before it occurs under external forces during mounting or operation, directly addressing the increased vulnerability of miniaturized components

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Volume of moving object

If the coil component is miniaturized, then the size is reduced, but the ease of recognizing inclination decreases

Engineering Contradiction:

Improvesize of coil componentVSAvoidease of recognizing inclination

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies local quality by placing recognition patterns at specific locations on the body surface, particularly at edge regions. These localized visual features provide inclination information without requiring the entire component to be larger, enabling easy recognition while maintaining miniaturization

Inventive Principle:

Principle #3Local quality

3Ease of operation

If a recognition pattern is added to identify mounting direction, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveease of identifying mounting directionVSAvoidcomplexity of coil component

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies color changes by using recognition patterns with different colors or reflectivity characteristics on the body surface. These visual differences provide clear mounting direction information without adding complex structural elements, maintaining simplicity while improving ease of operation

Inventive Principle:

Principle #32Color changes
