Solution Overview

Problem

Traditional transaction cards are often too large, necessitating a reduction in size while maintaining functionality to save space in wallets.

Innovation Solution

Designing transaction cards with reduced dimensions, incorporating an identification chip and magnetic stripe on one section and a textured grip on another, allowing for compact sizing without compromising functionality, and using materials like thermoplastics or metal for durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If transaction cards are reduced in size, then space efficiency in wallets is improved, but functionality and compatibility with existing devices may be compromised

Engineering Contradiction:

Improvecard sizeVSAvoidfunctionality compatibility

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The card is divided into distinct functional sections: a first section containing the identification chip and magnetic stripe for payment functionality, and a second section with a textured grip for handling. This segmentation allows each component to be optimally positioned within the reduced card dimensions while maintaining all necessary functions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the card are assigned different properties: the first section has smooth surfaces for chip and magnetic stripe accessibility, while the second section has a textured grip for enhanced handling. This local differentiation ensures that each area serves its specific function effectively within the compact overall design.

Inventive Principle:

Principle #3Local quality

2Volume of moving object

If components are concentrated in one section, then card size is reduced, but ease of operation may be affected

Engineering Contradiction:

Improvecard sizeVSAvoidcomponent accessibility

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The card utilizes both longitudinal and lateral dimensions strategically. The first section spans the full width but is confined to a specific longitudinal region, while the second section occupies the remaining longitudinal space. This two-dimensional arrangement maximizes component accessibility within the reduced overall dimensions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Provided are compact transaction cards. In some approaches, a transaction card may include a body having first and second main sides, a first and second end perimeter perimeters, and first and second side perimeters, wherein a first axis extending between the first and second side perimeters defines a first section of the body and a second section of the body. The card may further include an identification chip along the first main side and a magnetic stripe along the second main side, wherein the magnetic stripe extends between the first and second side perimeters, and wherein the magnetic stripe and the identification chip are located on the first section of the body. The card may further include a textured grip along at least one of the first main side and the second main side, wherein the textured grip is positioned only on the second section of the body.
