Solution Overview

Problem

Existing communication systems for vehicles lack efficient distribution of communication resources between subfunctions, leading to suboptimal performance and failure to address errors effectively, as they do not account for the optimal distribution of resources or participation of all components in error resolution.

Innovation Solution

A method for distributing communication resources between subfunctions of a communication system for vehicles, which involves ascertaining resource requirements, checking availability, and dynamically adjusting resource allocation to provide restricted executability levels, ensuring optimal performance by throttling non-essential components when resources are limited.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If communication resources are allocated to all subfunctions at full capacity, then each subfunction can operate at optimal performance, but the system fails when resources are insufficient and cannot dynamically adapt

Engineering Contradiction:

Improvesystem performanceVSAvoidresource adaptation capability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic resource allocation by allowing subfunctions to switch between different executability levels based on available communication resources. The system continuously monitors resource availability and adjusts the operational level of subfunctions in real-time, transforming a static resource allocation system into a dynamic one that adapts to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of subfunctions by introducing multiple executability levels (first level with full functionality, second level with restricted functionality). When communication resources are insufficient, the system modifies parameters such as data transmission frequency, resolution, or processing depth to reduce resource consumption while maintaining essential functionality.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the system prioritizes error resolution by all components, then error detection and response improve, but communication resource consumption increases

Engineering Contradiction:

Improveerror resolution capabilityVSAvoidcommunication resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by enabling selective participation in error resolution. Not all subfunctions must operate at full capacity during error conditions - instead, the system identifies which subfunctions are critical for error detection and response, and allows non-critical subfunctions to operate at reduced functionality or be temporarily deactivated, thereby conserving communication resources.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements partial action by allowing subfunctions to provide restricted executability levels during error conditions. Rather than requiring all subfunctions to operate at full capacity for error resolution, the system enables essential error handling with partial functionality of non-critical subfunctions, reducing overall communication resource consumption while maintaining safety.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If communication resources are restricted for non-essential subfunctions, then essential functions can maintain performance, but overall system functionality is reduced

Engineering Contradiction:

Improveessential function performanceVSAvoidoverall system functionality

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments the system into essential and non-essential subfunctions, allowing differential resource allocation. Critical safety functions maintain full executability levels while non-essential functions operate at restricted levels or are deactivated, enabling the system to preserve essential performance while accepting reduced overall functionality during resource-constrained conditions.

Inventive Principle:

Principle #1Segmentation

AI summary

A method for distributing communication resources between subfunctions of a function, executable on two or more executability levels, of a communication system for a vehicle. The method includes ascertaining a communication resource requirement of the function on a first executability level, provided by subfunctions of the function; checking whether the communication resource requirement is able to be met with available communication resources; if not, determining at least one of the subfunctions that is able, with the available communication resources, to provide only a second executability level that is restricted in relation to the first executability level; distributing available communication resources between the two or more subfunctions comprising restricting the available communication resources for one or more other subfunctions that differ from the at least one subfunction, so that the two or more subfunctions provide the second executability level of the function following the restriction.
