Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional card making equipment is used to manufacture electronic cards with power sources and EMV chips, then manufacturing efficiency is improved, but quality control standards and protection of sensitive electronic components deteriorate

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidquality control standards

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The manufacturing process is divided into two distinct phases: a protective pre-lamination phase using specialized equipment that embeds electronic components in a protective core, and a finishing phase using conventional card making equipment. This segmentation allows sensitive components to be protected during critical operations while maintaining overall manufacturing efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Electronic components are embedded in the pre-lamination core before the card making process begins. This preliminary action ensures that sensitive components are already protected and positioned correctly before undergoing lamination and personalization, preventing damage during subsequent manufacturing steps.

Inventive Principle:

Principle #10Preliminary action

2Length of stationary object

If thin sheets are used to meet ISO thickness requirements, then card thickness compliance is improved, but protection of sensitive electronic components during manufacturing deteriorates

Engineering Contradiction:

Improvecard thicknessVSAvoidprotection of sensitive components

Core Design Contradiction:

Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

Electronic components are nested within a protective pre-lamination core structure. This nested arrangement allows thin overall card thickness to be achieved while providing internal protection for sensitive components during manufacturing processes.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

A protective pre-lamination layer is applied beforehand to cushion and protect sensitive electronic components during manufacturing. This preliminary protective layer absorbs mechanical stresses during lamination and handling while maintaining the required thin profile for ISO compliance.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If power source is kept on continuously to ensure electrical connection, then reliability of power supply is improved, but energy consumption and risk of damage during manufacturing deteriorate

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The electrical connection between power source and CPU is made dynamic rather than static. The connection is established temporarily during activation and personalization, then permanently configured after manufacturing. This dynamic approach allows reliable power supply when needed while minimizing energy consumption and damage risk during storage and manufacturing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The power source operates periodically rather than continuously - activated temporarily during manufacturing processes that require it, then switched off. This periodic operation ensures power availability when needed while reducing overall energy consumption and preventing damage from continuous operation during storage and transport.

Inventive Principle:

Principle #19Periodic action

AI summary

Antenna and power control electrical circuits are configured for use with an initialization antenna for activating and personalizing an electronic core for electronic cards. When the antenna receives an RF signal, it turns on the power and redirects additional signals to a CPU. If the signal is validated, personalization information can be downloaded or self-diagnostic QC software can be activated; if a signal is not validated, the control circuits are reset. Once initialization is completed, the antenna control circuit is deactivated, and the power control circuit electrically connects the batter to the CPU.
