Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional chip placement methods in smartcards are ineffective in preventing chip removal and re-implantation, leading to increased risk of fraud and misuse.

Innovation Solution

A fraud prevention system that incorporates a chip pocket with a saw tooth milling pattern and a fraud prevention fluid, making it difficult to remove the chip and visibly or permanently marking the card if attempted, thereby reducing chip fraud.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional smooth milling patterns are used for chip placement, then manufacturing is simple and easy, but chip security is poor and chips can be easily removed

Engineering Contradiction:

Improvechip securityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies asymmetry by using a saw tooth milling pattern instead of a smooth symmetric pattern. The saw tooth pattern creates an uneven, asymmetric surface that mechanically interlocks with the chip, preventing easy removal while maintaining manufacturing feasibility through standard milling processes.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent utilizes curvature through the saw tooth pattern's geometric shape. The curved, angled surfaces of the saw tooth pattern create mechanical engagement with the chip, making removal difficult while allowing the pattern to be manufactured using conventional milling techniques.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Reliability

If chip pockets are made secure with complex patterns, then chip removal is prevented, but manufacturing cost and complexity increase

Engineering Contradiction:

Improvefraud preventionVSAvoidchip pocket structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The asymmetric saw tooth pattern provides effective fraud prevention through mechanical interlocking while maintaining relatively simple manufacturing. The pattern's geometry creates security without requiring complex multi-component structures, thus limiting the increase in device complexity.

Inventive Principle:

Principle #4Asymmetry

3Reliability

If fraud prevention fluid is added to the chip pocket, then tampering detection is improved, but device complexity and manufacturing steps increase

Engineering Contradiction:

Improvetampering detectionVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The fraud prevention fluid acts as an intermediary substance between the chip pocket structure and the chip. It provides tampering detection functionality by reacting to unauthorized removal attempts, while the fluid can be applied as a simple coating or injection step that integrates into existing manufacturing processes without major complexity increases.

Inventive Principle:

Principle #24Intermediary (Mediator)
