Mobile Inspection Laser Planes for Irregular Object Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile scanning inspection systems with anti-collision bumper protection are inadequate for objects with irregular contours, as they only provide point protection and fail to prevent collisions with vehicles or inspection arms when encountering objects of varying heights and shapes.
Innovation Solution
A mobile scanning inspection system equipped with first and second laser inspection planes on either side of the inspection tunnel, which emit parallel laser beams to provide comprehensive plane protection, and a controller that issues alarm signals and stops the vehicle movement when an object exceeds preset sizes, allowing for zonal collision prevention and height-exceeding protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-collision bumper with travel switch is used, then collision protection for regular-shaped objects is achieved, but protection for objects with irregular contours fails
Solution Approach 1:
The patent transitions from point-based protection (bumper bar) to plane-based protection (laser inspection planes). By emitting laser planes that form two-dimensional protective surfaces on both sides of the inspection tunnel, the system achieves comprehensive coverage for objects with irregular contours, heights, and shapes that cannot be protected by traditional point-based bumpers.
Solution Approach 2:
The protection system is divided into multiple laser inspection devices positioned at different locations (first inspection device on cross arm, second inspection device on vertical arm). Each device emits laser planes that cover specific zones, creating a segmented but comprehensive protective network throughout the inspection tunnel.
2Device complexity
If single point protection with bumper bar is used, then simple collision detection is achieved, but comprehensive coverage for varying object heights and shapes is lost
Solution Approach 1:
The system expands from one-dimensional point protection to two-dimensional plane protection using laser beams. The laser inspection planes extend across the inspection tunnel, creating extensive coverage areas that can detect objects of varying heights and shapes while maintaining a relatively simple device structure.
3Reliability
If laser inspection planes are emitted on both sides of inspection tunnel, then comprehensive collision protection is achieved, but system complexity increases
Solution Approach 1:
The laser inspection devices serve multiple functions: they emit inspection laser planes for collision detection, and simultaneously provide zonal collision indication by dividing the inspection plane into multiple detection zones. This multi-functionality reduces the need for additional separate components while achieving comprehensive protection.
Solution Approach 2:
The inspection system is segmented into multiple functional zones within the laser planes, allowing each inspection device to cover specific areas. This segmentation enables comprehensive coverage through strategic positioning of a limited number of devices rather than requiring dense coverage throughout the entire tunnel.
