Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device processes large amounts of data for evaluating multiple driving skill items, then the evaluation comprehensiveness is improved, but the hardware resource requirements increase and design flexibility decreases

Engineering Contradiction:
Improveevaluation comprehensivenessVSAvoidhardware resource requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the evaluation items into two categories: simple evaluation items (first plurality) and detailed evaluation items (second plurality). This segmentation allows the system to process different amounts of data selectively - basic evaluations use minimal data while comprehensive evaluations can access detailed metrics, thereby maintaining design flexibility while enabling comprehensive assessment when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of data processing volume based on evaluation type. For simple evaluation items, only essential travel data is processed, while for detailed evaluation items, additional detailed data is processed. This dynamic parameter adjustment reduces average processing load while preserving the capability for comprehensive evaluation when required.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the device outputs comments for numerous evaluation items, then the guidance effectiveness is improved, but the data processing load increases

Engineering Contradiction:
Improveguidance effectivenessVSAvoiddata processing load
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements partial action by selectively processing and outputting evaluation comments based on what is necessary for effective guidance. Not all evaluation items are processed to the same depth - simple items receive basic evaluation while detailed items receive comprehensive analysis only when needed. This partial processing approach maintains guidance effectiveness while reducing overall data processing load.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

Different evaluation items receive different levels of processing quality and detail. Simple evaluation items are processed with basic data while detailed evaluation items can access comprehensive data when needed. This local quality differentiation ensures that guidance is effective for each item's purpose without uniformly processing all items at maximum detail, thereby reducing total processing load.

Inventive Principle:
Principle #3Local quality
