Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual pre-setting is performed by users referring to layout information, then tracking can be performed according to store layout, but a lot of setup work is required

Engineering Contradiction:

Improvetracking accuracyVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The tracking device automatically acquires tracking information and determines feature points and sections without requiring user intervention. The system performs self-service by autonomously analyzing movement data and generating tracking configurations based on the monitoring region layout, eliminating manual setup work while maintaining tracking reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of the monitoring region and pre-determines feature points and sections before actual tracking begins. By pre-processing the spatial information and establishing tracking parameters in advance automatically, the system eliminates the need for manual pre-setting while ensuring tracking accuracy is maintained

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If manual pre-setting is performed by users, then tracking configuration can be customized, but the process is labor-intensive and prone to errors

Engineering Contradiction:

Improvetracking configuration flexibilityVSAvoidsetup complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical setup process with an automated information processing system. Instead of users manually configuring tracking parameters, the system uses acquisition units, feature point determination units, and section determination units to automatically process spatial information and generate tracking configurations, substituting human operation with automated computational processes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
