Solution Overview

Problem

Existing handheld biometric devices are not compact enough to efficiently capture biometric data and integrate with electronic devices for enhanced functionality, particularly in mobile operations.

Innovation Solution

A handheld device with a recess to accommodate an electronic device, such as a smartphone, allowing the device to be positioned below a biometric sensor for compact operation, featuring a sensor that can capture multiple skin areas and documents, with integrated electronics and wireless data transfer capabilities, and utilizing the smartphone's display for illumination and user guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the handheld device integrates electronic devices for enhanced functionality, then the functionality is improved, but the compactness deteriorates

Engineering Contradiction:

ImprovefunctionalityVSAvoidcompactness

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent implements a recess in the main body of the handheld device that temporarily receives an electronic device (such as a smartphone), allowing the electronic device to be nested within the handheld device structure. This enables enhanced functionality through integration with the electronic device while maintaining compactness when the electronic device is not in use, as the recess provides a built-in storage solution that does not permanently increase the device volume.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of moving object

If the electronic device is positioned below the sensor, then the compactness is improved, but the sensor illumination is worsened

Engineering Contradiction:

ImprovecompactnessVSAvoidsensor illumination

Core Design Contradiction:

Volume of moving objectVSIllumination intensity

Solution Approach 1:

The patent introduces a light guide as an intermediary component between the light source (display of the electronic device) and the sensor. The light guide efficiently directs and distributes light from the display to illuminate the sensor area, ensuring adequate illumination for biometric data capture while allowing the electronic device to be positioned below the sensor for compactness.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical illumination systems with the display of the electronic device as a light source. The display serves as both the user interface and the illumination source, eliminating the need for separate mechanical lighting components and enabling more compact positioning of the electronic device below the sensor.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the device is designed for one-handed operation, then the ease of operation is improved, but the device size is worsened

Engineering Contradiction:

Improveone-handed operationVSAvoiddevice size

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent segments the device into functional modules: a compact main body with sensor, a recess for electronic device, and integrated components. This segmentation allows the device to maintain a small form factor for one-handed operation while integrating additional functionality through the recess that temporarily receives the electronic device, effectively adding capabilities without permanently increasing size.

Inventive Principle:

Principle #1Segmentation
