Innovation Solution

An extendable vehicle electronics system comprising a base unit and an extension module with a processor that processes input data to generate output data for transmission to the base unit, allowing for the integration of new sensors and functional blocks without replacing the base unit, using wireless communication and power transfer for flexibility and compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If the base unit is upgraded with new hardware components, then the hardware capabilities and processing power are improved, but the integration complexity and compatibility issues increase

Engineering Contradiction:
Improveprocessing powerVSAvoidintegration complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The system is divided into a base unit and separate extension modules. Each module contains specific electronic components (sensors, processors, transceivers) that can be independently developed, tested, and upgraded without affecting the base unit. This segmentation allows new hardware capabilities to be added while maintaining the original system's stability and reducing integration complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base unit is designed with universal interfaces (module locator, base data transceiver) that can accommodate multiple different types of extension modules. The system supports various sensor types (cameras, microphones, radar) and communication protocols through standardized connection mechanisms, enabling one base unit to work with multiple functional extensions without requiring custom integration for each component.

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

2Adaptability or versatility

If the base unit is replaced to add new functionality, then the hardware capabilities are improved, but the cost and disruption increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The base unit is pre-equipped with universal interfaces and communication protocols during manufacturing, preparing it in advance to accept various extension modules. This preliminary configuration of module locators and base data transceivers with standardized protocols enables future functionality upgrades without requiring base unit replacement, thereby reducing costs and disruption.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If higher resolution sensor components are integrated, then the measurement precision is improved, but the communication protocol compatibility and data format compatibility deteriorate

Engineering Contradiction:
Improvesensor resolutionVSAvoidprotocol compatibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The extension module acts as an intermediary between high-resolution sensors and the base unit. The module data transceiver within the extension module handles communication with the base data transceiver, translating and adapting data formats and protocols. This intermediary layer enables high-resolution sensors to communicate effectively with the base unit without requiring changes to the base unit's existing communication infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the multimedia unit provides updated services, then the user experience is improved, but the system becomes outdated more quickly

Engineering Contradiction:
Improveuser experienceVSAvoidsystem lifespan
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The system is designed to be dynamically upgradable through the extension module architecture. New services and functionalities can be added by installing new extension modules without replacing the entire base unit. This dynamic capability allows the system to evolve and adapt to changing user experience requirements while extending the operational lifespan of the base unit, preventing it from becoming outdated.

Inventive Principle:
Principle #15Dynamics
