Solution Overview

Problem

Existing information processing systems for vehicle data require time-consuming searches within transmission frames to acquire vehicle information, making it inefficient for applications to find required data.

Innovation Solution

An information processing device that disassembles transmission frames into signals and stores their values in arrays, allowing for easier retrieval of vehicle information by referencing signal arrays rather than transmission frames, with additional elements for signal appearances and data classification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If applications reference transmission frames directly to acquire vehicle information, then the system maintains data integrity and completeness, but the search time and processing complexity increase significantly

Engineering Contradiction:
Improvesearch timeVSAvoiddata retrieval complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments transmission frame data into structured arrays organized by signal ID and reception sequence. Each array contains only relevant signal values, separating data by type and temporal order. This segmentation transforms the monolithic transmission frame structure into modular, easily searchable arrays, dramatically reducing search time while maintaining data integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-organizing transmission frame data into structured arrays before applications need to access them. The data is disassembled, categorized by signal ID, and stored in reception sequence order in advance, so that when applications need information, it is already in an optimized retrieval format, eliminating the need for time-consuming searches through raw transmission frames.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If the system stores all transmission frame data for complete information retrieval, then data completeness is maintained, but memory resource consumption increases

Engineering Contradiction:
Improvedata completenessVSAvoidmemory resource
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by organizing data arrays according to their specific characteristics - grouping by signal ID and arranging by reception sequence. Each array is tailored to store only the relevant data type with appropriate structure, rather than storing all data uniformly. This localized organization maintains complete information while optimizing memory usage through efficient data grouping and indexing.

Inventive Principle:
Principle #3Local quality

3Reliability

If the array size is set to accommodate maximum transmission frames, then overspill is prevented, but memory efficiency decreases when fewer frames are received

Engineering Contradiction:
Improvedata storage reliabilityVSAvoidmemory efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system implements dynamics by making the array structure adaptable to the actual number of received transmission frames. The arrays are configured with sufficient capacity to handle maximum expected frames, but only allocate and populate memory for the actual number of frames received. This dynamic approach ensures reliability by preventing overspill while maintaining memory efficiency by not allocating unnecessary memory when fewer frames are present.

Inventive Principle:
Principle #15Dynamics
