Solution Overview

Problem

Existing systems for managing electronic components in motor vehicles lack efficient methods to predict and manage resource consumption, leading to potential performance degradation and operational inefficiencies.

Innovation Solution

A method that involves predicting future resource consumption based on contextual data and past function implementations, comparing this consumption to a threshold, and restricting certain functions to prevent resource overload, thereby maintaining optimal performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple functions are implemented by the electronic component, then the functionality and versatility of the system is improved, but the resource consumption increases leading to potential performance degradation

Engineering Contradiction:
ImprovefunctionalityVSAvoidresource consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary prediction of future resource consumption by analyzing contextual data and past function implementations. This allows the system to determine which functions should be restricted before the resource threshold is exceeded, enabling proactive resource management rather than reactive control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the resource allocation parameters by comparing predicted consumption against a threshold and modifying function execution based on impact levels. This enables flexible adaptation of resource usage to maintain performance while supporting multiple functions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If functions are restricted to prevent resource overload, then performance degradation is prevented, but the functionality and operational capability is reduced

Engineering Contradiction:
Improveperformance stabilityVSAvoidfunctionality
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system applies different restriction strategies to different functions based on their impact levels on motor vehicle operation. Critical functions maintain full execution while non-critical functions are restricted, allowing differentiated quality of service rather than uniform restriction.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements partial restriction of functions rather than complete shutdown. By restricting only the necessary functions to bring resource consumption below the threshold, the system maintains adequate functionality while preventing performance degradation.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If resource consumption is monitored and managed proactively, then performance degradation is prevented, but the system complexity and management overhead is increased

Engineering Contradiction:
Improveperformance stabilityVSAvoidmanagement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system continuously monitors contextual data and past function implementations to predict future resource consumption. This feedback loop enables automatic adjustment of function execution based on predicted resource usage, simplifying management through automated decision-making.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The electronic component autonomously manages its own resource consumption by predicting future needs and self-adjusting function execution. This self-service capability eliminates the need for external management systems, reducing overall system complexity while maintaining performance stability.

Inventive Principle:
Principle #25Self-service
