Solution Overview

Problem

Existing vehicle safety systems lack effective coordination between stability-regulating systems and secondary safety components to enhance passive safety capabilities during dangerous vehicle conditions.

Innovation Solution

An electronic interface is established to communicate and control secondary safety components, such as seat belt tighteners and seat adjusters, based on data from vehicle stability-regulating systems like ESC, to anticipate and prepare for potential accidents by transitioning between normal and safety conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stability-regulating systems and secondary safety components operate independently, then system reliability is maintained, but passive safety capabilities cannot be enhanced through coordination

Engineering Contradiction:

Improvesafety system reliabilityVSAvoidpassive safety capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines the stability-regulating system (active safety) with secondary safety components (passive safety) through an electronic interface, enabling them to operate as an integrated coordinated system rather than independent systems, thus enhancing passive safety capabilities while maintaining reliability

Inventive Principle:

Principle #5Merging (Combining)

2Object-affected harmful factors

If secondary safety components are activated immediately during dangerous conditions, then occupant protection is maximized, but system complexity and energy consumption increase

Engineering Contradiction:

Improveoccupant injury riskVSAvoidsafety system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The electronic interface monitors regulating variable data from the stability-regulating system and activates secondary safety components in advance of actual collision, when dangerous conditions are detected, allowing preparation time without requiring immediate activation during the critical moment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The electronic interface serves as an intermediary between the stability-regulating system and secondary safety components, coordinating their operation based on monitored vehicle conditions, thus managing system complexity through a centralized control mechanism

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the electronic interface is implemented as a separate device, then system modularity is improved, but device complexity increases

Engineering Contradiction:

Improvesystem modularityVSAvoidelectronic interface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electronic interface is designed to perform multiple functions: monitoring regulating variable data from the stability-regulating system, determining when dangerous conditions exist, and controlling secondary safety components, thus reducing the need for separate dedicated devices for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)
