Solution Overview

Problem

Current financial transaction cards, such as credit and debit cards, are often made of plastic and lack a status element, with metal cards being costly and difficult to manufacture and personalize, while also being non-biodegradable and environmentally unfriendly.

Innovation Solution

A transaction instrument comprising a blended composite of metal and biodegradable polymer, specifically a high-gravity compound, which is biodegradable in whole or part, offering a cost-effective and environmentally friendly alternative with enhanced weight and personalization capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If metal cards are manufactured to provide weight and status, then the weight and status element are improved, but the manufacturing cost and complexity increase significantly

Engineering Contradiction:
Improvecard weightVSAvoidmanufacturing cost
Core Design Contradiction:
Weight of moving objectVSEase of manufacture

Solution Approach 1:

The patent applies composite materials by combining biodegradable polymer with metal fillers (such as stainless steel, aluminum, or other metallic particles) to create a transaction card that has enhanced weight and status characteristics. This composite approach allows the card to achieve metal-like weight without the high manufacturing costs and complexity associated with solid metal cards, while also enabling biodegradability

Inventive Principle:
Principle #40Composite materials

2Weight of moving object

If metal cards are used to provide status element, then the status and weight are improved, but the personalization and embossing capabilities deteriorate

Engineering Contradiction:
Improvecard weightVSAvoidpersonalization capability
Core Design Contradiction:
Weight of moving objectVSEase of manufacture

Solution Approach 1:

The composite structure of biodegradable polymer matrix with metal fillers provides a material that combines the weight benefits of metal with the formability and personalization capabilities of polymer materials. The polymer matrix allows for easier embossing, laser engraving, and other personalization techniques compared to solid metal, while the metal fillers provide the desired weight and status element

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If traditional plastic cards are used, then the manufacturing cost is reduced, but the environmental friendliness deteriorates due to non-biodegradability

Engineering Contradiction:
Improvemanufacturing costVSAvoidenvironmental impact
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the card material by using biodegradable polymers (such as polylactic acid, polyhydroxyalkanoates, or starch-based polymers) instead of traditional non-biodegradable plastics. This parameter change maintains cost-effectiveness while fundamentally improving the environmental profile by enabling the card to biodegrade naturally, reducing long-term waste accumulation

Inventive Principle:
Principle #35Parameter changes

4Object-generated harmful factors

If biodegradable polymer is used alone, then the environmental friendliness is improved, but the weight and status element deteriorate

Engineering Contradiction:
Improveenvironmental impactVSAvoidcard weight
Core Design Contradiction:
Object-generated harmful factorsVSWeight of moving object

Solution Approach 1:

The patent combines biodegradable polymer with metal fillers to create a composite material that maintains the environmental benefits of biodegradability while adding weight and status characteristics. The metal fillers (such as stainless steel powder, aluminum powder, or other metallic particles) are dispersed within the biodegradable polymer matrix to increase the overall density and weight of the card, providing the desired status element without compromising the biodegradable nature of the base material

Inventive Principle:
Principle #40Composite materials
