Integrated Card Swiping Device with Single Slot

Solution Overview

Problem

Conventional POS machines that integrate magnetic stripe and chip card reading capabilities are bulky and inconvenient for carrying and use due to separate slots for each type of card.

Innovation Solution

An integrated card swiping device with a casing containing a circuit board, magnetic head, card reader, and card support that allows for both magnetic stripe and chip card insertion through a single slot, reducing space occupation and eliminating the need to distinguish between card types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate card slots are provided for magnetic stripe cards and chip cards, then both card types can be read, but the device volume increases and portability decreases

Engineering Contradiction:

Improvecard reading capabilityVSAvoiddevice volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent combines the magnetic stripe reading function and chip card reading function into a single integrated card slot. The card support structure integrates both the magnetic head and card reader components, allowing both card types to be processed through one unified interface rather than requiring separate slots.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single card slot is designed to accommodate both magnetic stripe cards and chip cards universally. The card support structure and positioning mechanism are configured to handle different card types through the same opening, making the device multi-functional without requiring separate dedicated slots for each card type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate card slots are provided for magnetic stripe cards and chip cards, then both card types can be read, but the device becomes inconvenient to carry and use

Engineering Contradiction:

Improvecard reading capabilityVSAvoidportability and usability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines the magnetic stripe reading function and chip card reading function into a single integrated card slot. The card support structure integrates both the magnetic head and card reader components, allowing both card types to be processed through one unified interface rather than requiring separate slots.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If an elongated card swiping slot is provided at the lateral side for magnetic stripe cards, then magnetic stripe reading is enabled, but the device structure becomes complex and bulky

Engineering Contradiction:

Improvemagnetic stripe reading capabilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the magnetic stripe reading function and chip card reading function into a single integrated card slot. The card support structure integrates both the magnetic head and card reader components, allowing both card types to be processed through one unified interface rather than requiring separate slots.

Inventive Principle:

Principle #5Merging (Combining)
