Solution Overview

Problem

Existing biometric identification systems struggle to adapt automatically to individuals of different sizes and positions, such as standing or sitting, for secure and efficient capture of facial and fingerprint data.

Innovation Solution

A device with adjustable camera and fingerprint modules, controlled by a displacement mechanism, allows for independent height adjustment relative to a reference plane, forming a horizontal viewing axis for facial imaging and ergonomic support for fingerprint capture, using assignment data for personalized height settings based on individual size and position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device uses fixed positioning for camera and fingerprint sensor, then the device structure is simple, but it cannot adapt to persons of different sizes and positions

Engineering Contradiction:
Improveadaptability to different personsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustability by allowing the camera device and fingerprint sensor to be independently positioned along the vertical axis through a displacement device. This enables the device to adapt to different person heights and positions (standing or sitting) while maintaining a relatively simple overall structure through controlled mechanical movement rather than complete redesign.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent divides the device into independently adjustable modules: the camera device can be positioned separately from the fingerprint sensor along the vertical axis. This segmentation allows each component to be optimized for different persons without requiring complete reconfiguration of the entire device, balancing adaptability with structural simplicity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the camera and fingerprint device are adjusted independently, then adaptability to different persons is improved, but the device complexity increases

Engineering Contradiction:
Improveindividual adaptationVSAvoidadjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The displacement device serves multiple functions: it can adjust the camera device vertically, adjust the fingerprint sensor vertically, and potentially coordinate both adjustments. This multi-functionality reduces the need for separate adjustment mechanisms for each component, thereby limiting the increase in device complexity while maintaining individual adaptation capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If manual adjustment is used for each component, then adaptability is achieved, but the operation time increases

Engineering Contradiction:
Improveposition customizationVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements automated control where the controller automatically adjusts the camera device and fingerprint sensor to appropriate positions based on detection of the person's presence and characteristics. This self-service capability eliminates the need for manual adjustment by operators, achieving position customization while minimizing adjustment time through automated decision-making and actuation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms to detect person characteristics and automatically adjust component positions accordingly. The controller receives information about the person (such as height or position type) and uses this feedback to determine the optimal positioning of the camera and fingerprint sensor, enabling rapid adaptation without manual intervention.

Inventive Principle:
Principle #23Feedback

4Productivity

If automated detection and adjustment is implemented, then operation efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improveoperation efficiencyVSAvoidcontrol system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical adjustment with an automated control system that uses detection capabilities and electronic control to position the components. This substitution of mechanical manual operation with automated detection and control mechanisms improves operation efficiency while the complexity increase is managed through integration rather than multiplication of components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
