Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If data is collected through multiple different acquisition methods (QR code, Wi-Fi, BLE), then the quantity and variety of data increases, but the data formats become inconsistent and difficult to handle

Engineering Contradiction:

Improvequantity of dataVSAvoiddata format complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent creates a universal data structure that can accommodate multiple data acquisition methods (QR code, Wi-Fi, BLE) through a common format containing data ID, data value, and acquisition method identification. This universal structure allows diverse data sources to be handled uniformly, resolving the contradiction between data quantity and format complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter representation by introducing standardized data IDs and normalization processes. Instead of handling raw diverse formats, the system transforms data into a standardized parameter set (data ID, normalized value, acquisition method), making complex multi-source data manageable through parameter uniformity.

Inventive Principle:

Principle #35Parameter changes

2Loss of time

If data is transmitted frequently to ensure data freshness, then data utilization timeliness improves, but data waste increases due to redundant transmissions

Engineering Contradiction:

Improvedata utilization timelinessVSAvoiddata waste

Core Design Contradiction:

Loss of timeVSLoss of substance

Solution Approach 1:

The patent implements a feedback mechanism where the system determines transmission timing based on data type characteristics and changes in data values. The controller monitors data changes and selectively transmits only when necessary, preventing redundant transmissions while maintaining data freshness where needed.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent makes the transmission strategy dynamic by adjusting transmission frequency based on data type and change detection. Instead of fixed frequent transmission, the system adapts transmission timing to actual data characteristics, reducing waste while maintaining timeliness for critical data.

Inventive Principle:

Principle #15Dynamics

AI summary

A data processing device, a data processing method, or a non-transitory computer-readable storage medium storing a data processing program acquires first data that is data related to a vehicle by a preset first acquisition manner, acquires second data that is data related to an object other than the vehicle by a preset second acquisition manner, generates first standardization data including a first data ID and a first standard data value obtained by normalizing a value of the first data, and generates second standardization data including a second data ID and a second standard data value obtained by normalizing a value of the second data.
