Solution Overview

Problem

Existing movable apparatuses detect obstacles outside their actual path, leading to unnecessary collision avoidance processing and decreased operation efficiency.

Innovation Solution

An information processing apparatus that calculates a passing region through which the movable apparatus travels and sets an object detection range based on this region, using sensors like passive stereo cameras to detect only relevant obstacles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the detection range is widened to detect objects earlier, then the detection capability is improved, but the collision avoidance processing is performed unnecessarily frequently, causing delay in arrival at the destination

Engineering Contradiction:
Improvedetection capabilityVSAvoidarrival time at destination
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies local quality by differentiating the detection strategy based on spatial location. Objects within the passing region (where the movable apparatus actually travels) are detected with high priority, while objects outside this region are excluded from triggering collision avoidance processing. This selective detection approach maintains detection capability for relevant objects while avoiding unnecessary processing for irrelevant objects, thus resolving the contradiction between detection capability and arrival time.

Inventive Principle:
Principle #3Local quality

2Reliability

If obstacle detection is performed in all directions, then the safety is improved, but the operation efficiency decreases due to unnecessary collision avoidance processing

Engineering Contradiction:
ImprovesafetyVSAvoidoperation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements local quality by defining a passing region based on the movable apparatus's travel path and detecting objects only within this specific spatial zone. This approach ensures safety by detecting all objects that could potentially obstruct the path, while simultaneously improving operation efficiency by excluding objects outside the passing region from triggering collision avoidance maneuvers. The passing region is calculated considering the apparatus's position, orientation, and dimensions, creating a precise detection zone that balances safety and efficiency.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If the detection range is expanded to cover all potential obstacle areas, then the detection coverage is improved, but false alarms increase leading to unnecessary collision avoidance processing

Engineering Contradiction:
Improvedetection coverageVSAvoidfalse alarm rate
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent reduces false alarms by applying local quality through spatial filtering. Objects are detected and evaluated based on their position relative to the passing region. Only objects located within or intersecting the passing region are considered valid obstacles that require collision avoidance processing. Objects outside this region, even if detected by the sensor, are excluded from triggering avoidance maneuvers. This spatial discrimination maintains comprehensive detection coverage for relevant areas while eliminating false alarms from irrelevant detections.

Inventive Principle:
Principle #3Local quality
