Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the movement device holds complete map data for autonomous navigation in facilities with complicated structures, then navigation accuracy and space recognition capability are improved, but processing delay and power consumption increase due to increased computational load

Engineering Contradiction:
Improvespace recognition accuracyVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent divides the facility space into multiple management zones, each managed by a dedicated spatial information transmission device. The movement terminal only receives and processes spatial information for its current zone rather than the entire facility, segmenting the information processing task to reduce computational load and power consumption while maintaining accurate local navigation and space recognition capabilities

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides different levels of spatial information detail to different movement terminals based on their specific needs and current locations. Each terminal receives customized spatial information relevant to its current management zone, optimizing the balance between navigation accuracy and processing requirements for each device

Inventive Principle:
Principle #3Local quality

2Measurement precision

If the movement device holds complete map data for autonomous navigation in facilities with complicated structures, then navigation accuracy is improved, but processing delay occurs due to increased computational load

Engineering Contradiction:
Improvespace recognition accuracyVSAvoidprocessing delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent divides the facility space into multiple management zones, each managed by a dedicated spatial information transmission device. The movement terminal only receives and processes spatial information for its current zone rather than the entire facility, segmenting the information processing task to reduce computational load and processing delay while maintaining accurate local navigation and space recognition capabilities

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Spatial information for each management zone is pre-processed and stored in advance by the corresponding transmission device. When the movement terminal enters a zone, it receives pre-prepared spatial information immediately without requiring real-time processing of entire facility data, reducing processing delay while maintaining navigation accuracy

Inventive Principle:
Principle #10Preliminary action

3Reliability

If restriction information is provided to the movement device to control access to specific rooms, then security is improved, but the amount of information to be processed increases further

Engineering Contradiction:
Improvefacility securityVSAvoidinformation processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the necessary restriction information relevant to each management zone and provides it to the movement terminal when needed, rather than providing all facility-wide restriction data. This extraction approach maintains security control while reducing the complexity of information processing at the movement device

Inventive Principle:
Principle #2Taking out (Extraction)
