Solution Overview

Problem

Automatic teller machines (ATMs) face challenges in efficiently reading various forms of information within limited installation spaces, requiring multiple data reading units which complicates the configuration and limits the placement of reading devices.

Innovation Solution

An ATM design incorporating a first reading sensor above a second reading sensor, where the first sensor reads display information and the second sensor reads storage information from the same medium, allowing for efficient acquisition of multiple information types in a compact space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple data reading units are provided to read various forms of information (display information and storage information), then the reading capability is improved, but the device configuration becomes complicated

Engineering Contradiction:

Improvereading capabilityVSAvoidconfiguration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple data reading units (first reading sensor for display information and second reading sensor for storage information) into a single integrated reading device. This merging approach allows the device to read various forms of information from the medium while maintaining a unified, less complex configuration, directly resolving the contradiction between reading capability and configuration complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple data reading units are provided to read various forms of information, then the reading capability is improved, but the installation space requirement increases

Engineering Contradiction:

Improvereading capabilityVSAvoidinstallation space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent employs a nested arrangement where the first reading sensor and second reading sensor are positioned at different heights (first sensor above, second sensor below) but both read from the same predetermined position on the medium. This nesting approach allows multiple reading functions to be compactly integrated, improving reading capability while minimizing the installation space required.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Volume of moving object

If reading devices are arranged in limited spaces, then the device size is reduced, but the placement options for reading devices are limited

Engineering Contradiction:

Improvedevice sizeVSAvoidplacement flexibility

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent utilizes the vertical dimension by arranging the first reading sensor above the medium and the second reading sensor below the medium at different heights. This three-dimensional arrangement allows multiple reading devices to be compactly integrated in a limited space while maintaining their respective reading functions, effectively resolving the contradiction between device size and placement flexibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An automatic teller machine includes: a first reading sensor that reads display information displayed on a medium at a predetermined position; and a second reading sensor that reads, from the medium at the predetermined position, storage information stored in the medium. The first reading sensor is disposed above the second reading sensor.
