1Reliability

If subsurface scanning data is acquired and analyzed to identify hidden objects, then safety and efficiency are improved, but device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A ground penetrating radar system is introduced as an intermediary device between the construction vehicle and the hidden objects in the material pile. The radar system emits electromagnetic waves that penetrate the material, reflect off hidden objects, and provide subsurface scanning data. This intermediary enables non-contact detection of hidden objects, improving safety without requiring direct physical interaction with the material pile.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces reliance on mechanical sensing and operator experience with electromagnetic field-based detection. Instead of using mechanical probes or visual inspection, the ground penetrating radar uses electromagnetic waves to detect the presence, position, and characteristics of hidden objects. This substitution eliminates the need for physical contact and provides comprehensive subsurface information.

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

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The ground penetrating radar system performs preliminary scanning of the material pile before the construction vehicle begins operation. The system acquires subsurface scanning data in advance, allowing the vehicle to plan its operations based on pre-identified hidden objects and material characteristics. This preliminary action eliminates the need for trial-and-error operations and reduces downtime.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system processes subsurface scanning data to provide feedback about the material pile's structure, hidden objects, and potential hazards. This feedback information is used to adjust the construction vehicle's operations in real-time, optimizing efficiency by avoiding unnecessary maneuvers and ensuring safe operation. The feedback loop continues throughout the operation, adapting to changing conditions.

Inventive Principle:

Solution Approach 1:

The ground penetrating radar system enables the construction vehicle to self-detect and self-navigate around hidden objects without relying on operator experience. The system automatically acquires subsurface data, processes the information to identify hazards, and provides guidance for safe operation. This self-service capability eliminates the variability in operator performance and ensures consistent safety standards.
