Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If permanently installed infrastructure sensors are used to generate environmental models, then comprehensive environmental coverage is achieved, but installation effort and system complexity increase significantly

Engineering Contradiction:
Improveenvironmental model accuracyVSAvoidinstallation effort
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent transforms the static sensor infrastructure into a dynamic system by deploying mobile reconnaissance units that can move throughout the environment. These units dynamically adjust their positions to capture environmental data from multiple locations, replacing the need for numerous fixed sensors while maintaining comprehensive coverage through coordinated movement patterns.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses neural radiance fields to create virtual copies of the physical environment. By capturing images from mobile reconnaissance units and processing them through NeRF algorithms, the system generates accurate 3D environmental models without requiring physical sensors at every location, thus reducing installation complexity while preserving measurement precision.

Inventive Principle:
Principle #26Copying

2Area of stationary object

If fixed camera grids are installed in high-bay warehouses to capture narrow aisles, then complete area coverage is achieved, but installation cost and maintenance complexity increase

Engineering Contradiction:
Improvecoverage areaVSAvoidinstallation cost
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The mobile reconnaissance units serve multiple functions: they capture images for environmental modeling, navigate autonomously through narrow aisles, and can be deployed or repositioned as needed. This multi-functionality replaces the need for dedicated fixed cameras in each location, reducing overall system cost while maintaining complete area coverage.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of static cameras fixed in grid patterns, the patent employs dynamic mobile units that can adapt their positions and orientations. These units move through narrow aisles and adjust their capture angles to cover areas that would require numerous fixed cameras, thereby reducing installation cost while preserving comprehensive coverage.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If mobile sensors are used instead of fixed infrastructure sensors, then installation effort is reduced and flexibility increases, but measurement consistency and coverage reliability may deteriorate

Engineering Contradiction:
Improvedynamic adjustment capabilityVSAvoidmeasurement consistency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where mobile reconnaissance units continuously report their positions, orientations, and captured images to a central system. This feedback enables real-time adjustments to navigation paths and capture strategies, ensuring that measurement consistency is maintained despite the mobile nature of the sensors. The system adapts to maintain reliable coverage based on incoming data quality and environmental conditions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces mechanical fixed sensor mounts with software-based autonomous navigation systems. Mobile reconnaissance units use computer vision, SLAM (Simultaneous Localization and Mapping), and path planning algorithms to maintain measurement consistency without physical infrastructure. This substitution provides flexibility while preserving reliability through intelligent software control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Speed

If numerous fixed sensors are deployed to capture dynamic environmental changes, then real-time monitoring capability is improved, but system complexity and power consumption increase

Engineering Contradiction:
Improvereal-time update rateVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent uses mobile reconnaissance units that dynamically move through the environment rather than maintaining numerous fixed sensor positions. This dynamic approach allows the system to concentrate sensing resources on areas with changing conditions, reducing overall power consumption while maintaining real-time monitoring capability through targeted data collection and efficient navigation.

Inventive Principle:
Principle #15Dynamics
