Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing passive activation systems in motor vehicles face inefficiencies in optimizing the transmission of requests to locate portable activation means, leading to increased complexity and resource usage, which can result in failed location processing due to excessive requests exceeding the capacity of the protocol driver.

Innovation Solution

The implementation of an intermediate management layer that receives, stores, and prioritizes requests based on predetermined priority and oldness criteria, grouping compatible requests and sending them as a single signal to the portable activation means, thereby reducing the software and send/receive resources required for location determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple use-case modules send location requests to the protocol driver simultaneously, then the system can process multiple functionalities, but the complexity of exchanges increases and transmission efficiency is limited

Engineering Contradiction:

Improvefunctionalities processingVSAvoidexchanges complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a management layer as an intermediary between use-case modules and the protocol driver. This management layer receives, prioritizes, and groups location requests before forwarding them to the protocol driver, thereby reducing the complexity of direct exchanges while maintaining the ability to process multiple functionalities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The management layer groups multiple compatible location requests into a single transmission to the protocol driver. By merging requests that can be processed together, the system reduces the number of exchanges and improves transmission efficiency while still supporting multiple functionalities.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If the number of location requests exceeds the protocol driver capacity, then more functionalities can be accessed, but location processing fails

Engineering Contradiction:

Improvefunctionalities accessVSAvoidlocation processing

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The management layer implements periodic processing of location requests by prioritizing them and grouping them into manageable batches that are sent to the protocol driver at controlled intervals. This ensures that the protocol driver is not overwhelmed while maintaining continuous functionality access.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The management layer performs preliminary prioritization and grouping of requests before they reach the protocol driver. By preparing requests in advance and organizing them according to priority criteria, the system ensures that critical location processing tasks are handled reliably even when the number of requests exceeds baseline capacity.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If requests are processed individually by use-case modules, then each module has autonomy, but software resources and send/receive resources are excessively consumed

Engineering Contradiction:

Improvemodule autonomyVSAvoidsoftware resources consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The management layer serves multiple use-case modules simultaneously, providing a universal service for request prioritization and grouping. This multi-functional approach allows individual modules to maintain autonomy while sharing common resource management capabilities, thereby reducing overall software resource consumption.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for transmitting in a passive activation system in a motor vehicle. Between each use-case module and a protocol driver an intermediate management layer is inserted that receives requests from the modules and stores them in a list according to oldness and priority ranking, selects a main request with the highest priority ranking, selects requests compatible with the main request, sends at least one grouped signal corresponding to the main and compatible requests to a portable activation device, receives back from the activation device at least one signal transmitted to the intermediate layer allowing the activation device to be located and then the location thereof to be sent to the case modules that sent the main request or a compatible request, and deletes the main and compatible requests from the list.
