Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If biometric data capture is performed using existing mobile terminals with assistant support, then data capture capability is achieved, but accessibility and convenience are limited due to requirement of trained personnel and expensive infrastructure

Engineering Contradiction:
ImproveAccessibility and convenience of biometric data captureVSAvoidRequirement for assistant and infrastructure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile terminal enables users to independently capture and verify their own biometric data through automated authentication and verification processes, eliminating the need for trained personnel or complex infrastructure. The device performs self-verification of biometric authenticity and automatically manages data capture without external assistance.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If autonomous biometric capture is implemented without assistant, then accessibility and convenience are improved, but trustworthiness and verification reliability may be compromised

Engineering Contradiction:
ImproveIndependent biometric data captureVSAvoidTrustworthiness of biometric data
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mobile terminal incorporates an automated verification unit that provides immediate feedback on the authenticity of captured biometric data. The system continuously monitors and verifies biometric characteristics in real-time, comparing them against stored reference data to ensure trustworthiness while maintaining autonomous operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary authentication and verification checks before finalizing biometric data capture. The verification unit pre-validates the authenticity of biometric characteristics during the capture process, ensuring reliability is established before the data is finalized and stored.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If expensive infrastructure and trained personnel are used for biometric capture, then verification reliability is ensured, but costs and device complexity increase

Engineering Contradiction:
ImproveVerification reliability of biometric dataVSAvoidInfrastructure and personnel requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the verification functionality from complex external infrastructure and integrates it directly into the mobile terminal. The verification unit is embedded within the device itself, removing the need for separate verification systems, trained personnel, or expensive external infrastructure while maintaining verification reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The invention relates to a mobile terminal (104) for capturing the biometric data (BD) of a user (112). The terminal comprises: - a data storage device (216) with an authorization certificate (BN) and an indication of a permissible period; - an authentication module (304); - a sensor (208, 210) for capturing the user's biometric data; - a watch (232); - a control unit (316) configured to automatically or semi-automatically capture the user's biometric data (BD) using the sensor only after successful mutual authentication of the user and the mobile terminal; - a verification unit (308) for automatically verifying the authenticity of the captured biometric data.The control unit is configured to store the captured biometric data in the data storage (216) in a protected form only if the captured biometric data is genuine according to the verification and if the current time recorded during biometric data capture falls within the permissible time period. The authentication module (304) is configured to authenticate an operator (106) to the mobile terminal using additional authentication data (AD3) assigned to the operator. The control unit is configured to allow the reading of the protected biometric data only in the event of successful operator authentication, in order to transfer the read biometric data to a security document (116).
