Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric identification equipment is installed on the door handle, then vehicle security is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvevehicle securityVSAvoidstructure modification

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a wireless relay device as an intermediary component that mediates between the existing vehicle electrical system and the biometric authentication system. This relay device, equipped with a relay communication module, receives authentication results from the mobile device carrier's biometric identification module and controls power supply accordingly, without requiring direct integration into the door handle structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the need for physical modification of mechanical door handle structures with a wireless communication-based solution. Instead of installing biometric sensors directly on the door handle, the system uses wireless communication protocols to transmit authentication data and control signals, eliminating mechanical installation complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If biometric identification equipment is installed on the door handle, then vehicle security is improved, but manufacturing cost increases

Engineering Contradiction:

Improvevehicle securityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The wireless relay device serves multiple functions: it acts as a communication interface, a power control switch, and an authentication decision-maker. By consolidating these functions into a single universal device that can work with various biometric authentication systems, the patent reduces overall system cost and simplifies manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses the mobile device carrier's existing biometric identification capabilities (fingerprint, face, iris recognition already present in smartphones) rather than requiring separate dedicated biometric hardware in the vehicle. This copying approach leverages existing technology to achieve security without additional expensive specialized equipment.

Inventive Principle:

Principle #26Copying

3Reliability

If biometric identification equipment operates continuously, then vehicle security is improved, but power consumption increases

Engineering Contradiction:

Improvevehicle securityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The wireless relay device operates in a periodic manner, activating only when authentication is needed. The relay communication module enters sleep mode during normal operation and wakes up only when power supply changes are required or when authentication events occur, significantly reducing overall power consumption compared to continuous operation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system leverages the mobile device carrier's existing processing power and biometric identification capabilities to perform authentication, rather than requiring the vehicle's system to continuously monitor and process biometric data. The vehicle's wireless relay device simply receives and acts on authentication results, minimizing its own power consumption.

Inventive Principle:

Principle #25Self-service
